Donna will win because she eats 4.4 pies per minute and Joe eats 4 pies per minute.
Pie eaten by Donna: 11 pies / 2.5 minute = 4.4 pies per minute
Pie eaten by Joe: 10 pies / 2.5 minute = 4 pies per minute

You want to find the height of a tower used to transmit cellular phone calls. You stand 100 feet away from the tower and mesure

nevsk [136]

Answer:

84 feet to the nearest foot.

Step-by-step explanation:

We have a right angled triangle with adjacent side (A) = 100 and you want to find the height of the tower, the opposite side (O).

A = 100 , O = ? so we need the tangent , (from SOH-CAH-TOA).

tan 40 = O/ 100

O = 100 tan 40

= 83.9 feet.

MrRissso [65]

Answer:

C and F were correct by B is NOT 3 it is 1/3.

In order for 8^B to equal to 2 then it must be 8^1/3

B = 1/3

C = 16

F = 4,096

For the given quadratic equation convert into vertex form, find the vertex and find the value for x=6 Y=-2x^2+2x+2

Serga [27]

Answer:

Part 1) The vertex is the point (0.50,2.50)

part 2) $y=-58$

Step-by-step explanation:

we have

$y=-2x^{2} +2x+2$

Part 1) Convert into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-2=-2x^{2} +2x$

Factor the leading coefficient

$y-2=-2(x^{2} -x)$

Complete the square. Remember to balance the equation by adding the same constants to each side

$y-2-0.50=-2(x^{2} -x+0.25)$

$y-2.50=-2(x^{2} -x+0.25)$

$y-2.50=-2(x-0.50)^{2}$

$y=-2(x-0.50)^{2}+2.50$ -----> equation in vertex form

The vertex is the point (0.50,2.50)

Part 2) Find the value of y for x=6

substitute the value of x in the equation

$y=-2(6)^{2} +2(6)+2$

$y=-72 +12+2$

$y=-58$
