Given: f(x) = 3x² -5x + 4

To find f(-2), simply substitute x = -2 in function f(x).

f(-2) = 3(-2)² -5(-2) + 4

f(-2) = 12 + 10 + 4

f(-2) = 26

Answer: 26

Answer:

Part 1) The length of the new rectangle is $87.5\ ft$

Part 2) The area of the new rectangle is $4,375\ ft^{2}$

Step-by-step explanation:

we know that

If two rectangles are similar, then the ratio of its corresponding sides is proportional

step 1

Find the length of the new rectangle

Let

L-----> the length of the new rectangle

$\frac{50}{20}=\frac{L}{35}\\ \\ L=50*35/20\\ \\L=87.5\ ft$

step 2

Find the area of the new rectangle

we know that

The area of the rectangle is

$A=LW$

we have

$L=87.5\ ft$

$W=50\ ft$

substitute

$A=(87.5)(50)=4,375\ ft^{2}$

Answer:

Step-by-step explanation:

For a. the 14.7 represents the pressure that the air puts on you all the time.

For b. the d represents the depth you go under the surface of the water.

For c. we have to solve p(d) when d = 8:

p(8) = 14.7 + 0.445(8) so

p(8) = 14.7 + 3.56 and

p(8) = 18.26 psi
