Answer:
degree measure of arc AB = 120°
length of arc AB = 40π/3 in.
Step-by-step explanation:
arc AB has the same measure as its central angle. So, arc AB = 120°
120 is 1/3 of 360, Therefore, the length of arc AB is 1/3 of the circumference.
Therefore, the
length of arc AB = 1/3πd = 1/3π(40) =
= 40π/3 in.
Let log5 125 = x
Removing log you get 5^x = 125
Rewrite 125 as 5^3
Now 5^x = 5^3
x = 3
Answer:
(2, –3) is a solution to the system of linear equations.
Step-by-step explanation:
3x - y = 9
4 x + y = 5.
Add the equations
7x = 14
x = 2
Substitute it back into either original equation to find x
3(2) - y = 9
6 - y = 9
y = -3
4(2) + y = 5.
8 + y = 5
y = -3
x = 2
y = -3
(2, -3)
(2, –3) is a solution to the system of linear equations.
0.08 plus 0.3 is 0.38 because the “0.08” is in the tenths place not the single digit place so “0.3” is really 0.30 and then u add the 0.08
