Answer:
both are equal is 0
Step-by-step explanation:
After substituting, the answer is 0 to both
 
        
             
        
        
        
158.71 rounded to the nearest ten dollars would be $160.00
 then to estimate 10% since 10% starts with a 1, just remove the zero from both numbers
 so 160 becomes 16
 the tip would be $16

The answer is -2,686
let me tell you why !
the answer would be negative, since the parachutist is descending. so 158 × 17 = 2,686
make that negative.

Chain rule:
if
y=y(u) and u=u(x)
The dy/dx=(dv/du)(du/dx)
In our case
y=arcsin(u)
u=sin(x)
dy/du=1/√(1-u²) = 1/√(1-sin²x)
du/dx=cos x
dy/dx=cos x /√(1-sin²x)
Answer: dy/dx=cos x /√(1-sin²x)
