Answer: 40 questions
Step-by-step explanation:
set it up as an equation
38/x = 95/100
cross multiply
95x=3800
solve for x
x=40
We have to evaluate cos(2θ), knowing that θ is in the first quadrant and in standard position P(u,v) = (3,4).
We can picture this as:
We can write the relation:

We now look at the identities to find cos(2θ):

There are many identities for cos(2θ), but this is expressed in the information we already know, so we can solve as:

Answer: cos(2θ) = -7/25
Hello there!
We've already given the formula so I will not be adding it here.
We are also given that π = 3 for this problem.
r is defined as 'radius'
Radius is a point from center to one of endpoints.
Look at the image, the radius is given as 7cm.
From the information we gathered:
Substitute in the formula.

Cancel 3 out.

Evaluate 7^3

Multiply

Therefore, the volume is 1372.
