What Is The Equation Of The Circle?

Answers

Answer 1

Answer: C: (x - 4)² + (y+2)² = 25

Step-by-step explanation:

The formula for a circle is: (x - h)^2 + (y - k)^2 = r^2

Using this, the formula should be:

C: (x - 4)² + (y+2)² = 25

O y = -x + 10
O y = 10x + 1
O y=-10x - 9
O y=-5x - 9

Answers

Answer:

y = -5x + 9.

Step-by-step explanation:

Lets look for the relation between x and y.

Try the first one:

When x = -2, y = -(-2) + 10 = 12  

In the table y = 1 so its not this one.

Number 2:

x = -2, y = 10(-2) + 1  = -18 - Not thios one

Number 3:

When x = -2, y = -10(-2)  - 9 = 11

Not this one

Number 4:

y = -5(-2) - 9 = 1

This is the one.

Check again with x = 0:

When x = 0, y = -5(0) - 9 = -9.

Step-by-step explanation:

You got 91% of the questions right out of 175. In math words, this is saying that:

[tex]\frac{91}{100}*175=x[/tex]

[tex]x=159.25[/tex]

So, you got 175 - 159 = 15.75 questions wrong. The decimal could be from getting only part of a question wrong. So you got partial credit for one question

8x<=8

Okay, so,

5x < -3x + 8
(NOTE: The less than or equal to sign is represented as a less than sign since I am typing on a phone :P)

You can add three to both sides to even out the expression like so:

8x < 8

A balloon archway has been ordered for decorating the high school gym for a 1950's
style prom. The archway will contain 417 balloons, each holding 1.1 liters of helium.
Each balloon has a mass of 0.027 grams when empty, and all the string and fixings
that hold the balloons together total another 36 grams. If helium has a density of
0.1785 grams per liter, what is the mass of the entire archway.

Answers

We will see that the total mass of the entire archway is M = 129.1578g

What is the mass of the entire archway?

We know that each ballon weighs 0.027 grams for the plastic.

Now, we also need to remember the relation:

mass = density*volume.

Here, the density of helium is 0.1785 g/L

And the volume of each ballon is 1.1 L, then the mass of helium in each ballon is:

m = (0.1785 g/L)*(1.1 L) = 0.1964 g

Then the total mass of each ballon is:

M = 0.1964 g + 0.027g = 0.2234g

And there are 417 ballons, so the total mass (also adding the 36 grams for the strings) is:

Mass = 417*0.2234g + 36g = 129.1578g

Find the axis of symmetry and
the
vertex of the graph of y = 3x^2
-18x + 17

Answers

Answer:

vertex: (3, -10)

axis of symmetry:  x = 3

Step-by-step explanation:

Vertex form of a quadratic equation:  [tex]y=a(x-h)^2+k[/tex]

(where (h, k) is the vertex)

Rewrite the given equation in vertex form by completing the square.

Given equation:

[tex]y=3x^2-18x+17[/tex]

Add 10 to both sides:

[tex]y+10=3x^2-18x+27[/tex]

Factor RHS:

[tex]y+10=3(x^2-6x+9)[/tex]

[tex]y+10=3(x-3)^2[/tex]

Subtract 10 from both sides:

[tex]y=3(x-3)^2-10[/tex]

Therefore, the vertex is (3, -10)

The axis of symmetry is the x-value of the vertex.  
Therefore, the axis of symmetry is x = 3.

Answer:

Axis of symmetry: x = 3

Vertex: (3, -10)

Step-by-step explanation:

y = 3x² - 18x + 17

Axis of symmetry formula: x = [tex]\sf{\frac{-b}{2a}}[/tex]

a = 3b = -18

[tex]\sf x={\frac{-b}{2a}}\implies \textsf{Substitute -18 for b and 3 for a}\\\\\sf\ x={\frac{-(-18)}{2(3)}}\implies\textsf{multiplying 2 negatives makes a positive}\\\\\sf\ x={\frac{18}{6}}\implies \textsf{divide}\\\\\ \boxed{\sf x=3}\implies \textsf{axis of symmetry}[/tex]

Now, substitute 3 for x in your original equation to find the value of y:

y = 3x² - 18x + 17

y = 3(3)² - 18(3) + 17 <== exponents first

y = 3(9) - 54 + 17 <== multiply

y = 27 - 54 + 17 <== subtract

y = -27 + 17 <== add

y = -10

Vertex: (3, -10)

The GRE is an entrance exam that many students are required to take in order to apply to graduate school. In 2014, the combined scores for the Verbal and Quantitative sections were approximately normally distributed with a mean of 310 and a standard deviation of 12.

What is the probability that a randomly selected score is greater than 334? Write your answer as a decimal

Answers

Using the normal distribution, it is found that there is a 0.0228 probability that a randomly selected score is greater than 334.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 310, \sigma = 12[/tex]

The probability that a randomly selected score is greater than 334 is one subtracted by the p-value of Z when X = 334, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{334 - 310}{12}[/tex]

Z = 2

Z = 2 has a p-value of 0.9772

1 - 0.9772 = 0.0228.

0.0228 probability that a randomly selected score is greater than 334.

Answers

Answer:

Hello! Here are your answers for Part A:

4(x + 6) - 11 = 25 is a multi-step equation.

-1/2(2/3a - 4) = 1/2a - 7 is an equation with rational coefficients.

y - 23 = 8 is a one-step equation.

-3m - 2 = -17 is a two-step equation.

For Part B:

Find the common denominator -

x/2 - 7 = 4

x/2 + 2(-7)/2 = 4

Combine the fractions with the common denominator -

x/2 + 2(-7)/2 = 4

x + 2(-7)/2 = 4

Multiply the numbers -

x + 2(-7)/2 = 4

x - 14/2 = 4

Multiply all terms by the same value to eliminate fraction denominators -

x - 14/2 = 4

2 * x - 14/2 = 2 * 4

Cancel multiplied terms that are in the denominator -

2 * x - 14/2 = 2 * 4

x - 14 = 2 * 4

Multiply the numbers -

x - 14 = 2 * 4

x - 14 = 8

Add 14 to both sides -

x - 14 = 8

x - 14 + 14 = 8 + 14

Simplify -

x - 14 + 14 = 8 + 14

x = 8 + 14

x = 22

The solution to this equation is 22. 6 is NOT a solution.

This cost will be depreciated straight-line to zero over the project's three-year life, at the end of which the sausage system is estimated to have zero value. The project has no impact on net working capital. Each year during its three year life, the new system will increase the firm’s Sales by $455,000 and its Operating Cash Flow by $123,300.

$35,389

$1,136,217

Answers

Based on the net cashflow over the three year life, the NPV that Sausage Hut will realize is -$17,891.

What is the Net Present Value?

First find the present value of the increased cashflows. As it is a constant amount of $123,300, we can treat it as an annuity.

Present value = Amount x (Present value of annuity interest factor, 9%, 3 years)

= 123,300 x 2.5313

= $312,109.29

The net present value is:
= Present value of cashflows - Amount invested

= 312,109.29 - 330,000

= -$17,890.71

= -$17,891.
