the height h (in feet) of an object thrown vertically upward from a tower 144 feet tall is given by h=144+128t-16t², where t mea

Musya8 [376]

It takes 9 seconds to hit the ground.

Setting the equation equal to 0, we have:
0 = 144 + 128t - 16t²

Factoring out the GCF, we have
0 = 16(9 + 8t - t²)

Factoring out -1, we have:
0 = -16(-9 - 8t + t²)

In standard form, this is
-16(t² - 8t - 9) = 0

This is easily factorable; -9(1) = -9 and -9+1 = -8:
-16(t-9)(t+1) = 0

Using the zero product property, we know either t-9=0 or t+1=0; therefore t=9 or t=-1. Since negative time makes no sense, t=9.

Answer:

sin(B) = 12/13

cos(B) = 5/13

tan(B) = 12/5

csc(B) = 13/12

sec(B) = 13/5

cot(B) = 5/12

Step-by-step explanation:

If ABC is a right triangle, assuming that ∠C = 90°, then the segment AB =13 is the hypotenuse and the other two sides are:

$BC = 5\\AC = \sqrt{13^2 - 5^2}\\AC = 12$

The six trigonometric functions of angle B are:

$sin(B) =\frac{AC}{AB}= \frac{12}{13}\\cos(B) = \frac{BC}{AB} =\frac{5}{13}\\tan(B) = \frac{AC}{BC} =\frac{12}{5}\\\csc(B) =\frac{1}{sin(B)}= \frac{13}{12}\\sec(B) = \frac{1}{cos(B)} =\frac{13}{5}\\cot(B) = \frac{1}{tan(B)} =\frac{5}{12}\\$
