The function of f(x)=8√x gives the speed in feet per second (ft/s) of a free falling object after it has fallen x feet (ignoring

Juliette [100K]

Answer:

c. 55.4 ft/s

Step-by-step explanation:

Speed of the object is represented by the function:

$f(x)=8\sqrt{x}$

where x represents the number of feet the object has fallen. We have to find the speed of the object after it has fallen 48 feet. This means we have to find f(x) for x = 48. Substituting x = 48 in above equation we get:

$f(48)=8\sqrt{48}\\\\ =8\sqrt{16 \times 3}\\\\ =8\sqrt{4^{2} \times 3}\\\\ = 8 \times 4 \sqrt{3}\\\\ =32\sqrt{3}\\\\ = 32 \times 1.732\\\\ = 55.4$

Thus, rounded to nearest tenth, the speed of the object after it has fallen 48 feet would be 55.4 ft/s

What is an equation of the line that passes through the points (−5,6) and (7, 6)

enyata [817]

Answer:

y = 6

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-5, 6) and (7, 6). Substitute:

$m=\dfrac{6-6}{7-(-5)}=\dfrac{0}{12}=0$

The slope m = 0. Therefore it's a horizontal line y = a.

In the given points we have y = 6.
