14. Evaluate the following logarithms.
a. log base 3 of 13
b. log base 5 of 2

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
