Answer:

The provided statement is TRUE.

Step-by-step explanation:

The function f is an expression in variable x.

The entire expression can either be denoted by f (x) or y.

For instance consider the quadratic expression:

f (x) = ax² + bx + c

≡ y = ax² + bx + c

So, on computing the value of f (2), it implies that we are computing the value of y for x = 2.

Thus, the provided statement is TRUE.

If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.

shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

$h(t) = -16t^2 + 144$

When will the object hit the ground?

It hits the ground after t seconds, and t is found when $h(t) = 0$ . So

$h(t) = -16t^2 + 144$

$0 = -16t^2 + 144$

$16t^2 = 144$

$t^2 = \frac{144}{16}$

$t^2 = 9$

$t = \sqrt{9}$

$t = 3$

3 seconds, so the correct answer is given by option a.

To cover a rectangular region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?

L=length=15.5 ft; W=width; A=area=>170.5 sq ft

L*W=>170.5 sq ft Divide each side by L

W=>170.5 sq ft/L

W=>170.5 sq ft/15.5 ft=>11 feet
