(Quadratics) find the maximum of -16x^2 + 64x +8

Mathematics

Answer:

The max of this function is 72.

Step-by-step explanation:                                    -b

The x-coordinate of the vertex is given by x = ---------

                                                                               2(a)

which in this case is x = 2.

The value of -16x^2 + 64x +8 at x = 2 is f(2) = 72.

The max of this function is 72.

F(2)=20(1.25)^x<br> STEP BY STEP
Nezavi [6.7K]
F(2) = 20(1.25)^x

f(2) = 20(1.25)^2 - plug in 2 to x

f(2) = 20(1.5625) - calculate 1.25^2

f(2) = 31.25 - simplify

The area of a rectangle in 24 units. A diagonal drawn from one corner to another divides the rectangle into two right triangles.
nlexa [21]

Answer:

12 sq u

Step-by-step explanation:

Ⓗⓘ ⓣⓗⓔⓡⓔ

Well, assuming the shaded triangle is one of those two triangles, its area would be 12 sq u.

Why? Because its length would be the same as the retances, as would its height, and to find the area of a triangle, you'd do L*H/2 which would be 24/2=12 sq u

6) Parking lot A charges $19.00 to enter the parking lot plus $1.50 per hour
Olegator [25]

Answer:

4 Hours.

Step-by-step explanation:

You would set this up as an equality where x represent hours

19.00 + 1.50x = 14+2.75x

You then get the x on one side by subtracting 14 from both sides and 1.50x from both sides.

5 = 1.25x

Divide both sides by 1.25 to x by itself.

4 = x
