On a coordinate plane, a parabola opens up. It goes through (negative 7.5, 4), has a vertex of (negative 3, negative 9), and goe

morpeh [17]

Answer:

f(-3) = -9.

Step-by-step explanation:

The equation of the curve in vertex form is:

f(x) = a(x + 3)^2 - 9 a is positive as the parabola opens up.

It passes through the point (1.5, 4), so

4 = a(1.5 + 3)^2 - 9

20.25a = 13

a = 13/20.25

a = 0.6420.

So the equation of the graph is

0.6420(x + 3)^2 - 9.

f(-3) = 0.6420(-3 + 3)^2 - 9

= 0.642*0 - 9.

= -9.

The area of a rectangle is 99 ft^2, and the length of the rectangle is 7 more than double the width. Find the dimensions of the

Sergio039 [100]

Answer:

width =5.5ft

length =18

Step-by-step explanation:

w=x

L=2x+7

area=w*L

99 = x(2x+7)

$99=2x^{2} +7x$

$2x^{2} +7x-99=0$

$2x^{2} +18x-11x-99=0$

2x(x+9)-11(x+9)=0

(2x-11)(x+9)=0

2x-11=0

2x=11

x=11/2

x=5.5

L=2x+7=2*5.5+7=11+7=18
