We are given with the expression <span> (1 - cos x) / (x^2)</span><span> and asked to evaluate the expression to limit as theta approaches zero. In this case, we substitute first zero. cos infinity is 1. The answer is zero over zero. This is indeterminate so we derive the terms according to L'hopital's rule. The derivative is sin x /2x. sin infinity is 1. 1/infinity is equal to zero. Hence the answer is zero.</span>
What do you think the answer is? Tell me and I will help you some more! :)
Answer:
path area =379.94ft^2
Step-by-step explanation:
Total radius = 11 feet.
Area = Pi x r^2
Area = Pi x 11^2
Area = Pi x 121
Area = 379.94 ft^2
Answer:
28.57%
Step-by-step explanation:
Given data
Initial cost =$28
Final cost =$36
Required
The percentage change in cost
Percent change =final - initial/initial*100
Substitute
Percent change =36-28/28*100
Percent change =8/28*100
Percent change =0. 2857*100
Percent change =28.57%
(15a^4 - 30a^5 )/5a^2
= 5a^2(3a^2 - 6a^3) / 5a^2
= 3a^2 - 6a^3
or
= - 6a^3 + 3a^2
