Answer:
x ≈ - 1.28
Step-by-step explanation:
Using the rule of logarithms
x = n ⇔ x = 
Given
ln(x + 4) = 1 , then
x + 4 =
( subtract 4 from both sides )
x =
- 4 = - 1.28 ( to the nearest hundredth )
Multiply it out.
I believe the answer would be 15x^2 - 20x.
However, functions is not my forte.
Soooo
yeah
Answer:
radius=7.5, diameter=13
Step-by-step explanation:
diameter is the length across a circle through the middle, and it is given in the picture. radius is half of the diameter
Using the empirical rule 68% would fall within one standard deviation of the mean.
The standard deviation is given as 2 inches and the mean is 49 inches.
Since it is only one standard deviation find the lower number by subtracting the standard deviation from the mean and find the higher number by adding the standard deviation to the mean.
49 - 2 = 47
49 + 2 = 51
68% would be between 47 inches and 51 inches tall.
