6 cans of paint for a total of 90 dollars spent
I multiplied 120 by .20 to get 24 and subtracted it from 120 to get the amount that still has to be painted which is 96.
96 divided by 16 is 6 which is the number of cans of paint needed to paint the rest. Then just multiply by the cost (15$) and the answer is 90$

If f(x) = 7x2 - 4x, what is the value<br> of f(2)?<br> F -8<br> J 17<br> G 2<br> K 20<br> H 6
kow [346]

Answer:

K 20

Step-by-step explanation:

f(x) = 7x2 - 4x

f (2) = 7 (2)^2 - 4(2)

= 28 - 8

= 20

Since they replaced the x inside f(x) with 2, just do that the same to the right side, change all x into 2

Lauren dove into a swimming pool from a 15 foot high diving board with an initial upward velocity of 8 feet per second find the
slamgirl [31]
It will take Lauren 1.25 seconds to hit the water.

With the given information, we can write the following quadratic equation.

h=-16t^2+8tt+15

Now, just use the quadratic formula to solve the equation.

You will get 1.25 and -0.75 as the zeros of the equation (where Laruen hits the water).
Only 1.25 makes sense in the context of this problem.
