Answer:

minor arc

Step-by-step explanation:

Minor arc is shortest arc. It measures less.

Major arc is the longest arc. It measure more than minor arc.

Semicircle is the half of the circle

Here blue arc AB is the minor arc

Red arc AB is the major arc

Blue arc measures less than red arc

Answer:

N = 52 * (9/7)^(t/1.5)

Step-by-step explanation:

This problem can be modelated as an exponencial problem, using the formula:

N = Po * (1+r)^(t/1.5)

Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.

In our case, we have that N is the final number of branches after t years, Po = 52 branches, r = 2/7 and t is the number of years since the beginning (in the formula we divide by 1.5 because the rate is defined for 1.5 years)

Then, we have that:

N = 52 * (1 + 2/7)^(t/1.5)

N = 52 * (9/7)^(t/1.5)

Given sin b = .88 find angle b in radians

Rama09 [41]

$sin^{-1}0.88=61.642\ degrees$
There are pi radians in 180 degrees. Therefore to convert degrees to radians we need to divide by 180 and multiply by pi, as follows:
$\frac{61.642}{180}\times \pi=1.076\ radians$
