Do the functions have the same concavity? f(x)=-x^2+40x+120f(x)=−x 2 +40x+120f, left parenthesis, x, right parenthesis, equals, minus, x, squared, plus, 40, x, plus, 120

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

2

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
