Natalie launches a toy rocket from a platform. The graph below shows the height of the rocket ℎ h in feet after t seconds.

Answers

Answer 1

The x-coordinate (or t-coordinate) of the vertex is 1.5 seconds and represents the time at which the rocket reaches its maximum height. The y-coordinate (or h-coordinate) of the vertex is 334 feet and represents the maximum height reached by the rocket.

Describe Function?

A function is a mathematical relationship that describes how one quantity (the output or dependent variable) depends on one or more other quantities (the inputs or independent variables).

A function can be thought of as a machine that takes in input values, applies a set of rules or operations to them, and produces an output value. The input values can be any set of numbers or other objects that the function is defined for, and the output values can be any set of numbers or objects that the function can produce.

To find the x-coordinate (or t-coordinate) of the vertex, we can use the formula:

x = -b / (2a)

where a is the coefficient of the squared term, b is the coefficient of the linear term, and x represents the time at which the rocket reaches its maximum height. The equation of the parabolic function that models the height of the rocket is:

h = at² + bt + c

where h is the height of the rocket at time t.

We can use the coordinates of the points on the parabola to find the values of a, b, and c:

(0, 260): 260 = a(0)² + b(0) + c, so c = 260

(2, 324): 324 = a(2)² + b(2) + 260, so 4a + 2b = 64

(6.5, 0): 0 = a(6.5)² + b(6.5) + 260, so 42.25a + 6.5b = -260

We can solve this system of equations to find the values of a and b:

4a + 2b = 64

42.25a + 6.5b = -260

Multiplying the first equation by 3.25 and subtracting from the second equation, we get:

42.25a + 6.5b - 13a - 6.5b = -260 - 208

29.25a = -468

a = -16

Substituting a = -16 into the first equation, we get:

4(-16) + 2b = 64

b = 48

Therefore, the equation of the parabolic function is:

h = -16t² + 48t + 260

The x-coordinate (or t-coordinate) of the vertex is:

t = -b / (2a) = -48 / (2(-16)) = 1.5

The x-coordinate (or t-coordinate) of the vertex is 1.5 seconds and represents the time at which the rocket reaches its maximum height.

To find the y-coordinate (or h-coordinate) of the vertex, we can substitute t = 1.5 into the equation of the parabolic function:

h = -16(1.5)² + 48(1.5) + 260 = 334

Therefore, the y-coordinate (or h-coordinate) of the vertex is 334 feet and represents the maximum height reached by the rocket.

A cylinder fits perfectly inside a box. The width of the cylinder is 3 feet, and the space between
the cylinder and the box is filled with 15 gallons of oil, taking up 75% of the space. What is the
height of the box in feet?

Answers

The height of the box must be at least 2.9111 feet.

Define volume of the cylinder

The volume of the cylinder is given by the formula V = πr²h, where r is the radius of the cylinder and h is its height.

Since the width of the cylinder is 3 feet, the radius is 1.5 feet.

The volume of the oil is 15 gallons, which is equivalent to 0.2 cubic feet. We know that this volume of oil takes up 75% of the space between the cylinder and the box, so the total space between the cylinder and the box is 0.2 / 0.75 = 0.2667 cubic feet.

Since the cylinder fits perfectly inside the box, the volume of the box is equal to the volume of the cylinder plus the space between the cylinder and the box. Therefore, we have:

Volume of box = Volume of cylinder + Volume of oil

Volume of box = πr²h + 0.2667

Substituting the values we have:

Volume of box = π(1.5)²h + 0.2667

Volume of box = 7.0686h + 0.2667

To find the height of the box, we need to isolate h. We know that the volume of the box must be greater than or equal to the volume of the cylinder, so we can set up the inequality:

Volume of box ≥ Volume of cylinder

πr²h + 0.2667 ≥ πr²(3)

h + 0.0889 ≥ 3

h ≥ 2.9111

Therefore, the height of the box must be at least 2.9111 feet.

The density of gold is given as 5×2^2 grams/cm³, which means that one cubic centimeter of gold has a mass of 5×2^2 grams.

To find the mass of 8 × 25 cm³ of gold, we need to first find the total volume of gold:

Total volume = 8 × 25 cm³ = 200 cm³

Now we can use the density of gold to find the mass:

Mass = Density × Volume

Mass = (5×2^2 grams/cm³) × 200 cm³

Mass = 5 × 4 × 200 grams

Mass = 4000 grams

Therefore, the mass of 8 × 25 cm³ of gold is 4000 grams.

In the figure shown, m∠2 is 16 more than 3 times m∠1. Find the measure of each angle.

PLEASE LOOK AT PICTURE BELOW!!!!!! SHOW WORK PLEASEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

m∠1 = 41°

m∠2 = 139°

Step-by-step explanation:

Set variables:

1. ∠1 = x

2. ∠2 = y

Make first equation:

It says "m∠2 is 16 more than 3 times m∠1."

So let's convert that into an equation:

y = 16° + 3x

Now, by looking at the photo, we can tell that its a straight line, which is equal to 180°

Derived from that, we can get m∠1 + m∠2 = 180°, which in other "words" is x + y = 180°.

Great, now we have our 2 equations, and we just have to solve.

Equations:

1. y = 16° + 3x

2. x + y = 180°

Let's substitute what we have for y into the second equation:

x + (16° + 3x) = 180°

Solve:

(We can take out parentheses because it's a "+" sign)

Combine like terms:

4x + 16° = 180°

Subtract 16° from both sides

4x = 164°

Isolate x by dividing both sides by 4

x = 41°

Substitute:

Now that we have x = 41°, we can substitute that in for the equation - "y = 16° + 3x"

New Equation:

y = 16° + 3(41°)

Solve:

Multiply 3 and 41°, which is 123°

y = 16° + 123°

Simplify:

y = 139°

Reminder:

m∠1 = x

m∠2 = y

Therefore,

m∠1 = 41°

m∠2 = 139°

Hopefully this helps!

(If you want, please mark me brainliest tomorrow)

Answer:

Basically, a straight line is equal to 180 degrees. If angle 2 is 16 more than 3 times angle 1, we get the equation of y = 16 + 3x. Put them together and you get x + 16 + 3x = 180. Then you just solve, and get x = 41. Then you put x in for the other equation and get y = 139.

Which play would you choose to be on your team and why?

Answers

For Bob: Mean =10.13,MAD = 2.66,Median =10.5 ,IQR = 5.5,Q1 = 8,Q3 = 13.5

for alan :Mean =7.25,Median = 7.5,IQR = 10,Q1 = 4,Q3 = 14

How to find mean ?

For Bob:

Mean = (8+15+10+10+10+15+7+8+10+9+12+11+11+13+7+8+9+9+8+10+11+14+11+10+9+12+14+14+12+13+5+13+9+11+12+13+10+8+7+8) / 38 = 10.13

MAD = 2.66 (calculated using the median of Bob's data)

To calculate the median and quartiles for Bob's data, we need to first sort the data in ascending order:

5, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11, 12, 12, 13, 13, 13, 14, 14, 15, 15

Median = (10+11) / 2 = 10.5

Q1 = median of the first half of the data = (8+8) / 2 = 8

Q3 = median of the second half of the data = (13+14) / 2 = 13.5

IQR = Q3 - Q1 = 13.5 - 8 = 5.5

Therefore, for Bob:

Median = 10.5

IQR = 5.5

Q1 = 8

Q3 = 13.5

For Alan:

Mean = (2+3+4+5+7+10+12+14+15+16) / 10 = 7.25

MAD = 2.81 (calculated using the median of Alan's data)

Median = 7.5 (calculated as the average of the 5th and 6th value in Alan's sorted data)

Q1 = 4

Q3 = 14

IQR = Q3 - Q1 = 14 - 4 = 10

Therefore, for Alan:

Median = 7.5

IQR = 10

Q1 = 4

Q3 = 14

To determine if there are any outliers, we can use the following formula:

Outliers = data points outside the range [Q1 - 1.5(IQR), Q3 + 1.5(IQR)]

For Bob:

Lower outlier bound = 8 - 1.5(5.5) = -0.25

Upper outlier bound = 13.5 + 1.5(5.5) = 24.25

There are no outliers in Bob's data.

For Alan:

Lower outlier bound = 4 - 1.5(10) = -11

Upper outlier bound = 14 + 1.5(10) = 29

There are no outliers in Alan's data.

If the team needs a more consistent player with a higher median and narrower IQR, Bob might be a better choice. On the other hand, if the team needs a player who can potentially score more points, Alan might be a better choice as his mean is higher.

A 5 m ladder reaches 4.7 m up a wall. What angle does the ladder make with the wall?

Answers

The ladder makes an angle of approximately 19.94 degrees with the wall.

Calculating the angle of the ladder up on the wall

We can use trigonometry to solve for the angle between the ladder and the wall.

Let's call the angle we're looking for "theta" (θ). We can use the cosine function, which is defined as the ratio of the length of the adjacent side to the length of the hypotenuse side of a right triangle, to solve for theta:

cos(θ) = opposite/adjacent

So we have:

cos(θ) = 4.7/5

We can use a calculator to solve for theta:

cos(θ) = 0.94

Take the arc cos

θ ≈ 19.94 degrees

Therefore, the ladder makes an angle of approximately 19.94 degrees with the wall.

The probability that none of the four unrelated Caucasian people in the U.S. have AB- blood is approximately 0.9606 or 96.06%.

The problem states that the probability that a Caucasian person in the U.S. has AB- blood is 1%. This means that the probability of a Caucasian person not having AB- blood is 1 - 0.01 = 0.99.

The problem asks to find the probability that none of the four unrelated Caucasian people have AB- blood. Since we are assuming that the blood types of the four people are independent, we can multiply the probabilities of each person not having AB- blood to find the probability that none of them have AB- blood.

Using the multiplication rule of probability, we can calculate the probability of no AB- blood as:

P(No AB- in 4) = P(Not AB-) * P(Not AB-) * P(Not AB-) * P(Not AB-)

P(No AB- in 4) = 0.99 * 0.99 * 0.99 * 0.99

P(No AB- in 4) = 0.9606

Therefore, the probability that none of the four unrelated Caucasian people in the U.S. have AB- blood is approximately 0.9606 or 96.06%. This means that there is a high likelihood that none of the four people have AB- blood.

Step-by-step explanation:

If 50% of the album is empty, then 50% of the album is filled with stamps.

So, the total number of stamps that the album holds is 500, and half of that (50%) is filled with stamps, which is:

500 * 50% = 250 stamps

Each page holds 5 stamps, so the number of pages filled with stamps is:

A portfolio has a value P(E, S), so that the value P is a function of E, the price of a Euro in Canadian dollars, and S, the level of the TSX stock index. Presently the portfolio is worth $207,000, while a Euro is $1.50 Canadian, and the index is S = 18,000. If the partial derivatives of P have values ∂P ∂E = 80,000, and ∂P ∂S = −20, what approximately will the portfolio value be if the price of a Euro goes down by 0.07 and the stock index goes down by 629?

Answers

Answer:

The new value of the portfolio would be $207,000 - $18,180 = $188,820

Step-by-step explanation:

Using the first-order partial derivatives, we can calculate the approximate change in the portfolio value due to changes in E and S using the formula:

ΔP ≈ ∂P/∂E * ΔE + ∂P/∂S * ΔS

where ΔE is the change in the price of a Euro and ΔS is the change in the TSX stock index.

Given that ∂P/∂E = 80,000 and ∂P/∂S = -20, and the changes ΔE = -0.07 and ΔS = -629, we can plug in the values and get:

ΔP ≈ 80,000 * (-0.07) + (-20) * (-629)

≈ -5,600 - 12,580

≈ -18,180

Therefore, the portfolio value is expected to decrease by approximately $18,180 if the price of a Euro goes down by $0.07 and the TSX stock index goes down by 629 points. The new value of the portfolio would be $207,000 - $18,180 = $188,820.

a circulat region has a population of about 360,000 people and a population density of about 1415 people per square mile . find the radius of the region

Answers

To find the radius of the circular region, we need to know its area. We can use the formula for the population density:

Population density = Population / Area

Rearranging the formula to solve for the area, we get:

Area = Population / Population density

Substituting the given values, we have:

Area = 360,000 / 1415 = 254.78 square miles

The formula for the area of a circle is:

Area = πr^2

Solving for the radius, we get:

r = √(Area / π)

Substituting the calculated area, we have:

r = √(254.78 / π) ≈ 9.02 miles

Therefore, the radius of the circular region is approximately 9.02 miles.

Sure, to calculate the future value of the investment, we can use the formula:

FV = P(1 + r/n)^(n*t)

Where:

FV = Future Value
P = Principal (initial investment)
r = Annual interest rate
n = Number of times the interest is compounded per year
t = Number of years

In this case, P = $1500, r = 8.5%, n = 1 (compounded annually), and t = 14 years.

Plugging in these values to the formula, we get:

FV = 1500(1 + 0.085/1)^(1*14)
FV = 1500(1.085)^14
FV = $4,497.60

Therefore, the investment will be worth approximately $4,498 after 14 years (rounded to the nearest dollar).

A circle with equation (x + 2 )^2 + (y – 3 )^2 = 16 is graphed on the coordinate plane. Which represents the line of tangency at the point (–6, 3)?

Answers

The line of tangency at the point (–6, 3) is x = -6. So, the correct option is (b).

What is tangent?

In geometry, the tangent is a trigonometric function that relates to the angles and sides of a right triangle. Specifically, the tangent of an angle in a right triangle is the ratio of the length of the side opposite the angle to the length of the adjacent side.

To find the line of tangency to a circle at a given point, we need to first find the slope of the radius that passes through that point, and then take the negative reciprocal of that slope to get the slope of the tangent line.

Given the circle equation: (x + 2)² + (y - 3)² = 16, we can see that its center is at the point (-2, 3) and its radius is 4.

To find the slope of the radius passing through the point (-6, 3), we can use the point-slope formula:

(y - y1) = m(x - x1)

where m is the slope of the radius, and (x1, y1) is the center of the circle (-2, 3). Plugging in the values, we get:

(y - 3) = m(x + 2)

Substituting the point (-6, 3) into the equation, we get:

(3 - 3) = m((-6) + 2)

0 = -4m

m = 0

So the slope of the radius is 0. To find the slope of the tangent line, we take the negative reciprocal of the slope of the radius:

slope of tangent line = -1/0 = undefined

Since the slope of the tangent line is undefined, it must be a vertical line passing through the point (-6, 3). Thus, the line of tangency at the point (-6, 3) is the vertical line x = -6.

Lori is selling crafts at a show. She pays $43.20 for the table rental. She sells 18 items. Every item is the same price and Lori makes a total profit of $25.20. Part A Select all the equations that will yield the correct value for the sale price x of each item. 43.20 = 18x − 25.20 43.20 = 18x + 25.20 25.20 = 18x − 43.20 25.20 = 18x + 43.20 Part B What is the cost x of each item in dollars?

Answers

Answer:

43.20 = 18x + 25.20

x = $1.00

Step-by-step explanation:

43.20 - 18x = 25.20

43.20 = 25.20 + 18x

Solve for x:

18x = 43.20 - 25.20

18x = 18

x = 18/18 = $1.00

1 ) Finding the difference 4/9 - ⅖:

We require a common denominator to subtract fractions. The least frequent multiple of 9 and 5 in this example is 45. So we'll recast both fractions with 45 as the denominator:

[tex]\frac{4}{9} = \frac{20}{45} \\\frac{2}{5} = \frac{18}{45}[/tex]

Now we can subtract:

[tex]\frac{20}{45} - \frac{18}{45} = \frac{2}{45}[/tex]

Therefore, the difference between 4/9 and ⅖ is 2/45.

How will you find if the fraction is terminating or repeating?

Examine the prime factors of the denominator when the fraction is in its simplest elementary form to determine if it will have a terminating or repeating decimal. The decimal will end if they are made up of 2s and/or 5s.

2) calculating the quotient 2/9 / ⅚:

Fractions are divided by multiplying the first fraction by the reciprocal of the second fraction. So:

2/9 ÷ ⅚ = 2/9 x 6/5

Before multiplying, we can simplify:

2/9 x 6/5 = 12/45

And here's another example:

12/45 = 4/15

As a result, the quotient of 2/9 56 is 4/15.

3) Writing each terminating decimal as an integer quotient:

(a) 0.437 = 437/1000

(b) 8.2 = 82/10 = 41/5

4) Choosing whether each rational number will result in a repeated or terminating decimal:
