We are given with the expression y<span> = b cos t + t2 sin t and is asked to differentiate the function in terms of t. Based in the power law and law of products, we apply these to the given expresssion. the derivative is y' = -b sin t + t^2 * (cos t) + sin t * 2t. This is equal to </span>y' = sin t (-b +2t) + t^2 cos t.
Answer:
The length on the blueprint for an actual length of 65 feet is 
Step-by-step explanation:
Given:
Scale of the blueprint is 
Length of one side of the house is 65 feet.
Now, as per given data;
1 foot in actual =
on the blueprint.
Therefore, using unitary method, we can find find the length on the blueprint for an actual length of 65 feet by multiplying 65 and
. Therefore,
Length on the blueprint for 65 feet is given as:

Therefore, the length on the blueprint for an actual length of 65 feet is 
9/18 or 50% if you toss the coin because when you toss 1 coin you get a 1/2 chance of getting tails. Do that nine times and you get 9/18
