Answer:
68
Step-by-step explanation:
m7 + m8 = Straight line = 180
So, m7 = 180 - 112 = 68
Answer:
![log_372 = 3.8928](https://tex.z-dn.net/?f=log_372%20%3D%203.8928)
Step-by-step explanation:
Given
![log_38 = 1.8928](https://tex.z-dn.net/?f=log_38%20%3D%201.8928)
Required
Evaluate ![log_372](https://tex.z-dn.net/?f=log_372)
We have:
![log_372 = log_3(8 *9)](https://tex.z-dn.net/?f=log_372%20%3D%20log_3%288%20%2A9%29)
Apply law of logarithm
![log_372 = log_38 +log_39](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2Blog_39)
Express 9 as 3^2
![log_372 = log_38 +log_33^2](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2Blog_33%5E2)
Evaluate the exponents
![log_372 = log_38 +2log_33](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2B2log_33)
.
So:
![log_372 = log_38 + 2 * 1](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2B%202%20%2A%201)
![log_372 = log_38 + 2](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2B%202)
Substitute ![log_38 = 1.8928](https://tex.z-dn.net/?f=log_38%20%3D%201.8928)
![log_372 = 1.8928 + 2](https://tex.z-dn.net/?f=log_372%20%3D%201.8928%20%2B%202)
![log_372 = 3.8928](https://tex.z-dn.net/?f=log_372%20%3D%203.8928)
The distance of a door knob from the floor is about one hip I guess
Compounded depreciation formula:
A = P(1 - r)ⁿ , where P = original price, r= rate of depreciation, n = number of years and A = actual value (after depreciation):
A= $8000(1 - 11%)⁵ = 8000(0.89)⁵ = 4,467.24 ≈$4,467
Answer:
A. The rate is -2 each hour
B. It is decreasing, as the hours increase, the gallons decrease
