3 0

Answer:

Step-by-step explanation:

l=8

\theta=288 \pi /180=72\pi /45=8\pi /5\\\theta=\frac{l}{r} \\r=\frac{l}{\theta}=8 \times 5/(8 \pi )=5/\pi \approx 1.59

In triangle ABC, a=7, b=3 and cos C = 1/2. The value of c is
aalyn [17]

Answer:

Correct option: 2 -> sqrt(37)

Step-by-step explanation:

To solve this problem, we just need to use the law of cosines. This law is used to find the third side of a triangle, when we have the two other sides and the angle between them.

The equation of the law of cosines is:

c^2 = a^2 + b^2 - 2 * a * b * cos(C)

So, we have that:

c^2 = 7^2 + 3^2 - 2 * 7 * 3 * (1/2)

c^2 = 49 + 9 - 21

c^2 = 37

c = sqrt(37)

Correct option: 2

Since 1972 the US. inflation rate has averaged 4.8 % per year . Use the approximate doubling time formula to estimate the doubli
Artemon [7]

Answer:

14  3/4 years

Step-by-step explanation:

Let's assume compound inflation.  The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t    Find t, the time required for prices to double.

Then:

2   =  1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048)   =   14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.
