can the vertex also be a solution of a graphed parabola?

Answer:

(11√3)/3

Step-by-step explanation:

In order to solve for the variable, you will need to use a trig function. In this case, you will need to use the trig function tangent.

Tan = opposite/adjacent

⇒ Tan 30° = x/11

⇒ 11 · Tan 30° = x

⇒ (11√3)/3 = x

Answer:

50.24 in.

Step-by-step explanation:

Step 1: Define/explain/formula.

To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.

Definitions:

[tex]a=\pi r^2(3.14*radius*radius)[/tex]

Step 2: Solve.

The radius of this circle is 4.

Now, we simply plug the numbers into the formula.

[tex]\pi4^2(3.14*4*4)=50.24[/tex]

Step 3: Conclude.

Therefore, the area of this circle is 50.24 in.

Answer:

[tex] \tan(180 \degree + 30\degree) - 2 \tan(180\degree - 30\degree) \\ = \frac{ \sin(210\degree) }{ \cos(210\degree) } - 2 \frac{ \sin(150\degree) }{ \cos(150\degree) } \\ = \frac{ - 0.5}{ - \frac{ \sqrt{3} }{2} } - 2 \frac{0.5}{ - \frac{ \sqrt{3} }{2} } \\ = \frac{0.5 + 1}{ \frac{ \sqrt{3} }{2} } \\ = 0.693 \\ = ln(2) [/tex]

Answer:

77 this answer is rounded to the nearest tenth

Step-by-step explanation:

The formula for the are of a circle is A=πr² so thats π7² which is equaled to about 153.9 since this is a semicircle you'd divide that by two giving you 76.96902.

The area of the semi-circle with the radius of 4.1 mm, round to the nearest tenth is 52.8 mm²

The area of the semi-circle will be calculated by the formula -

Area = 1/2πr², where r is the radius of the circle.

Keep the values in formula to find the value.of area of semi circle

Area = 1/2×3.14×4.1²

Performing multiplication on Right Hand Side of the equation to find the area of the semi-circle

Area = 52.78 mm²

Round off the nearest tenth

Area = 52.8 mm²

Thus, the area of semi-circle with mentioned radius is 52.8 mm².

Step-by-step explanation:

Answer:

(-3, 5)

Step-by-step explanation:

parallelograms and relatively even shapes, so how ever far apart the bottom two vertices are apart is how far apart you would space the top ones. simply add the x coordinates absolute values (meaning ignore negative values for now) 6+0=0. 6 Units away from 3( top vertex is (3,7)) would be -3. for the y coordinates you gotta look at y coordinates of the top vertex and bottom right vertex. they're ten units apart. go ten up from -5( because the bottom left vertex is (-6,-5) and you get 5. so overall (-3,5) would be the last vertex

Answer:

(-3,5)

Step-by-step explanation:

Since parallelograms are relatively even shapes, the distance between the bottom two vertices determines the distance between the top two. Simply add the absolute values of the x coordinates (meaning ignore negative values for now) 6 + 0 = 0 -3 is 6 units away from 3 (top vertex is (3,7)). Look at the y coordinates of the top vertex and bottom right vertex for the y coordinates. They're separated by ten units. Since the bottom left vertex is (-6,-5) and you get 5, go ten up from -5.

The equation is (5 x 2) - (5 + 5) = 20

The given equation can be solved by performing the operations within the parentheses first.

First, 5 x 2 = 10, then 5 + 5 = 10.

Then, the next step is to subtract the second set of parentheses from the first set, 10 - 10 = 0.

Finally, we can see that 0 + 20 = 20.

In this equation, the operation of multiplication and addition are used and the final value is 20.

The value of x in this problem is 2.

Our given algebraic equation is 2.5 ( 6x - 4 ) = 10 + 4 ( 1.5 + 0.5x) and in this, we have to find the final value of x.

Use the transposing method to isolate the variable x and then solve for it.

distribute brackets on both sides of the equation.

= 2.5*6x - 2.5*4 = 10 + 4*1.5 + 4*0.5x

= 15x - 10 = 10 + 6 + 2x

collect terms in x to the left side and numeric values to the right side.

= 15x - 2x = 10 + 6 + 10

= 13x = 26

= x = 26/13 = 2

Therefore the final value of x in this equation will be 2.

There are several ways to make a graph to compare two sets of data, but one common method is to use a line graph.

The steps to create a line graph to compare two sets of data:

Organize the data: Arrange the data into two columns, one for each set of data. Each column should have a label at the top to indicate what the data represents.

Choose a scale: Decide on an appropriate scale for the x- and y-axes that will allow you to clearly display the data. The x-axis should represent the categories being compared, and the y-axis should represent the values of the data.

Plot the data: Using the chosen scale, plot the data points for each set of data on the graph. Use different colors or symbols for each set of data to make it easy to distinguish between the two.

Add a title: Give the graph a title that describes what the graph is showing.

Add a legend: Add a legend to the graph to indicate what each set of data represents.

Add labels: Label the x- and y-axes to indicate what they represent.

By following these steps, you can create a clear and informative line graph that allows you to easily compare two sets of data.

Other types of graph that can be used to compare two sets of data are bar charts, scatter plots, and stacked bar charts. The choice of graph depends on the type of data you have, and what you want to compare or highlight.

area = 6.25

Step-by-step explanation:

Every square has four equal sides. If we know one side is 2.5, then all sides are 2.5.

2.5*4 = 10

To find the area of a square you multiply the height and length. Since all sides of a square are the same, you just multiply 2.5 with itself.

2.5*2.5=6.25

The three steps which Patel could use to solve the quadratic equation include the following:

A. 8(x² + 2x + (2/2)²) = -3 + 8.

B. x = -1 ±√5/8

E. 8(x² + 2x) = -3.

In order to solve the given quadratic equation, we would use the completing the square method as follows;

Separating the variables in the quadratic equation from constant, we have the following;

8x² + 16x + 3 = 0

8x² + 16x = -3

By factorizing the common variables in the quadratic equation from constant, we have the following;

8(x² + 2x) = -3 (step 1).

By completing the squares in the brackets and then balancing the expression on the right-hand side, we have the following;

8(x² + 2x + (2/2)²) = -3 + 8 (step 2).

8(x² + 2x + 1) = -3 + 8

8(x + 1)² = 5

Dividing both sides of the quadratic equation by 8, we have the following;

(x + 1)² = 5

Taking the square root of both sides of the quadratic equation, we have the following;

(x + 1) = ±√5/8

x = -1 ±√5/8 (step 3).

At this rate, the ratio or proportion of red balloons to the total balloons, the number of red balloons out of 48 is 6.

Proportion describes the two or more ratios equated to each other.

Proportions are depicted as fractional values in decimals, fractions, or percentages.

In this situation, we equate the ratio or proportion of red balloons to the sample to determine the number that will likely be red.

The total number of balloons thrown in a water balloon fight = 6,960

The number of the balloons that are red = 870

The proportion of the red balloons to the total = 0.125 or 12.5% (870/6,960)

Answer:

(- 1, 9 )

Step-by-step explanation:

6x - y = - 15 → (1)

x + 2y = 17 → (2)

multiplying (1) by 2 and adding to (2) will eliminate y

12x - 2y = - 30 → (3)

add (2) and (3) term by term to eliminate y

13x + 0 = - 13

13x = - 13 ( divide both sides by 13 )

x = - 1

substitute x = - 1 into either of the 2 equations and solve for y

substituting into (2)

- 1 + 2y = 17 ( add 1 to both sides )

2y = 18 ( divide both sides by 2 )

y = 9

solution is (- 1, 9 )

Answer:

7/15

Step-by-step explanation:

number of favorable outcomes (red jelly beans) = 7

number of total outcomes (total jelly beans) = 7 + 2 + 6 = 15

probability of red = number of favorable outcomes/number of total outcomes = 7/15

The probability of getting a red jelly bean is 7/15

Total number of jelly beans in the jar (sum of all the jelly beans): 7+6+2= 15

Total number of red jelly beans: 7

Therefore, the probability of getting a red jelly bean= number of red jelly beans/ total number of jelly beans
