HELP ASAP PLSSSSSSSSSSSS
ludmilkaskok [199]

Answer:

f = .39

Step-by-step explanation:

d (v) = 2.15 v^2 / (64.4 f)

v = 40

d = 138

substitute these in

138 = 2.15 (40)^2 / (64.4 *f)

simplify

138 = 2.15 (*1600) / (64.4 *f)

138 = 3440 / (64.4 *f)

multiply each side by 64.4f

138 * 64.4 f = 3440

8887.2 f = 3440

divide by 8887.2

8887.2 f /8887.2= 3440/8887.2

f=.38707

to the nearest hundredth

f = .39

7. Expand and reduce A(x). Then calculate A(x) for x=1.<br> A (x) = (3x – 3)(3x + 2)
SashulF [63]

Given:

The function is

A(x)=(3x-3)(3x+2)

To find:

The simplified form of A(x) and value of A(x) at x=1.

Solution:

We have,

A(x)=(3x-3)(3x+2)

A(x)=(3x)(3x)+(3x)(2)+(-3)(3x)+(-3)(2)

A(x)=9x^2+6x-9x-6

A(x)=9x^2-3x-6

Putting x=1, we get

A(1)=9(1)^2-3(1)-6

A(1)=9-3-6

A(1)=9-9

A(1)=0

Therefore, the simplified form of A(x) is A(x)=9x^2-3x-6 and the value of A(x) at x=1 in 0.
