Since opening night, attendance at Play A has increased steadily, while attendance at Play B first rose and then fell. Equations

Y_Kistochka [10]

Answer:

On 5th day and 13th day Attendance was equal for both plays and it was

231 for each .

Step-by-step explanation:

In order to find same attendance ,we need plug both equation equal

-x^2+26x+126 = 8x+191

-x^2+26x-8x+126-191 = 0

-x^2 +18x-65 =0

multiplying both sides by -1 ,we get

x^2 -18x+ 65 =0

(x-5) (x-13) =0

x =5 and x =13

On 5th day and 13th day attendance was same.

And attendance can be obtained by plugging x =5 in either of equation

y = 8(5)+191

= 40 +191

= 231

In the diagram,

forsale [732]

Answer:

Probability that the measure of a segment is greater than 3 = 0.6

Step-by-step explanation:

From the given attachment,

AB ≅ BC, AC ≅ CD and AD = 12

Therefore, AC ≅ CD = $\frac{1}{2}(\text{AD})$

= 6 units

Since AC ≅ CD

AB + BC ≅ CD

2(AB) = 6

AB = 3 units

Now we have measurements of the segments as,

AB = BC = 3 units

AC = CD = 6 units

AD = 12 units

Total number of segments = 5

Length of segments more than 3 = 3

Probability to pick a segment measuring greater than 3,

= $\frac{\text{Total number of segments measuring greater than 3}}{Total number of segments}$

= $\frac{3}{5}$

= 0.6

What is the surface area of a square prism with sides that measure 8 units?

V125BC [204]

Answer:

The surface area of square prism = 384 units squared

Step-by-step explanation:

Explanation:-

Given the square prism side 'a' = 8 units

The surface area of square prism = 2 a² + 4 a h

Given square prism length , width and height also equal identical sides

The surface area of square prism = 2 a² + 4 a h

= 2(8)² + 4 (8)(8)

= 2(64) + 4(64)

= 384 units squared

Final answer:-

The surface area of square prism = 384 units squared

PLEASE HELP!! Write an equation of g(x) that represents an exponential base “e” parent function with the following transformatio

Montano1993 [528]

Answer:

$g(x) = 12 {e}^{ - x - 7}$

Step-by-step explanation:

The parent function is

$g(x) = e {}^{x}$

First it is asked to reflect over the y axis so using the rule

$g(x) = g( - x)$

Our function looks like

$g(x) = e {}^{ - x}$

Then we are asked to shift the equation to the right 7. When shifting to the right or move the x axis, instead of adding 7 we would want to subtract 7 since the x axis is the independent variable and we must respect the y axis which is the dependent so using the rule

$g(x) = g(x - h)$

When subtracting a 7 it looks like now

where h is the number we move . Now we are asked to apply a vertical stretch of 12. Since vertical stretch refers to the y axis, we are just going to multiply the function by 12 using the rule

$g(x) = a \times g(x)$

where a is the vertical stretch. So now it would look like

$g(x) = 12 {e}^{ - x - 7}$
