Identify PR rounded to the nearest tenth. Please help asap!!

kicyunya [14]

Trigonometric Functions:

$S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}$

$Sine\frac{Opposite}{Hypotenuse} Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}$

You have the angle and the adjacent. You need to find the hypotenuse (PR). Therefore, you use cos.

$Cos(26)=\frac{13}{H}$

Rearrange the formula to find H (PR):

$H = \frac{13}{Cos(26)}$

Disregarding wind resistance the distance a body falls from rest varies directly as th squares of the time it falls if a skydive

Firdavs [7]

Answer:

The skydiver will fall 1600 ft in 10 seconds.

Step-by-step explanation:

<u>Distance a body falls from rest varies directly as the squares of the time it falls </u>

Let distance = s

time = t

Therefore , s = k $\times t^{2}$

Given, the body falls 64 ft in 2 seconds.

Substituting in above equation,

64 = k $\times (2)^{2}$

64 = k $\times (4)$

k = $\frac{64}{4}$

k = 16 ft/ $s^{2}$

We have to find how much he will fall in 10 seconds.

s = k $\times t^{2}$

s = $16 \times 10^{2}$

s = $16 \times 100$

s = 1600 ft
