Answer:

11.) n + 7 = 18

31.) n - 9 = 22

7.) 5 · m = 35

50.) m/5= 10

15.) 18 + s = 33

17.) 40 - s = 23

3.) 27 = 9 · s

6.) 18/s = 3

5.) m + m + 12 = 22

2.) m + 14 = 18 - m

Answer:

a) r(t) = 0.783t radians

b) h(t) = 30cos(0.783*t) feet

Step-by-step explanation:

The situation is depicted in the picture attached

<h3>(see picture) </h3>

Since the angular speed is constant, to find an expression for the angle r(t) in radians we just cross-multiply using the fact that 1 min = 60 seconds

4.7 radians __________ 60 seconds

r(t) radians ____________ t seconds

$\large \displaystyle\frac{4.7}{r(t)}=\displaystyle\frac{60}{t}\Rightarrow r(t)=(4.7/60)t \Rightarrow\\\\\boxed{r(t)=0.783t\;rad}$
