Answer:
g'(10) = 
Explanation:
Since g is the inverse of f ,
We can write
g(f(x)) = x <em> </em><em>(Identity)</em>
Differentiating both sides of the equation we get,
g'(f(x)).f'(x) = 1
g'(10) = 
--equation[1] Where f(x) = 10
Now, we have to find x when f(x) = 10
Thus 10 = 
+ 2
= 8
x = 
Since f(x) = + 2
f'(x) = -
f'() = -4 × 4 = -16
Putting it in equation 1, we get:
We get g'(10) = -
C) The weight of the object on planet A will be less than the weight of the object on planet B.
This happened because: when gravitational pull of a planet is weak, an object will weigh less as a result of less gravity forcing it down to the ground.
Anything can happen once. You want to be able to show consistency and have more people confirm your answer
Explanation:
h=((usinx)^2)/2g
12.7=((usin(19))^2)/(2×9.8)
(12.7×2×9.8)=(usin(19))^2
248.92=(usin(19))^2
usin19 =√248.92 =15.78
U =15.78/(sin19)
=48.46m/s----> speed
