Answer:
y = 1x + 6
Step-by-step explanation:
y = 1x + b
-1 = 1(-7) + b
-1 = -7 + b
6 = b
Answer:
75°
Step-by-step explanation:
In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.
In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5
We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105
x is the supplement of 105. 180-105=75
Answer:
The population in 2015 will be 165 million.
Step-by-step explanation:
The exponential growth formula is given by:
Where:
a: is the initial population
r: is the rate of increase
Δt: is the time
With the initial information we can find the rate:
Using logarithm:
Using exponential:
Now, we can find the estimated population in 2015:
Therefore, the population in 2015 will be 165 million.
I hope it helps you!
Yes. If you can express it as a fraction (=ratio) then it is rational. 0.8 is the same as 8/10.
