The question is in the picture below, if you could show all your work so i can see how to do it, that would be appreciated.

m∠R = 27.03°

Solution:

Given In ΔQRP, p = 28 km, q = 17 km, r = 15 km

To find the measure of angle R:

Law of cosine formula for ΔQRP:

Substitute the given values in the above formula.

Switch the given equation.

Subtract 1073 from both side of the equation.

Divide by –952 on both sides.

Hence m∠R = 27.03°.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
