Answer:
m = 
Step-by-step explanation:
I'm assuming by m, you mean the slope.
You have two points. (-11, 5) and (2, -4)
- m = change in y-value ÷ change in x-value
1) Substitute in the points.
m = 
2) Solve.
So, the slope would equal
.
1. 22: 154 (divide 154 by 22)
1:7
if the figures are similar the ratio's of side lengths must be the same
12:b
multiply 12 by 7 to get side b
b = 84
Choice C
2: 1: 25 is the scale factor
6:tree
we need to multiply by 25
6*25 = 150
Choice C
Answer:
(See explanation and attachment below for further details)
Step-by-step explanation:
The parabola must satisfy the following conditions:


The expression for the x-intercepts are, respectively:
x = -3
![4 = C\cdot [(-3)^{2} - 2\cdot k\cdot (-3)+k^{2}]](https://tex.z-dn.net/?f=4%20%3D%20C%5Ccdot%20%5B%28-3%29%5E%7B2%7D%20-%202%5Ccdot%20k%5Ccdot%20%28-3%29%2Bk%5E%7B2%7D%5D)

x = 5
![4 = C\cdot [5^{2}-2\cdot k \cdot (5)+k^{2}]](https://tex.z-dn.net/?f=4%20%3D%20C%5Ccdot%20%5B5%5E%7B2%7D-2%5Ccdot%20k%20%5Ccdot%20%285%29%2Bk%5E%7B2%7D%5D)

By equalizing both expressions:



And,


The equation of parabola is:

Answer:
The population of the world is 200 times of the population of Canada.
Step-by-step explanation:
Given that,
Canada's population = 
The population of world = 
We need to find how many times larger is the population of the world compared to Canada's population. It can be solved as follows :

So, the population of the world is 200 times of the population of Canada.
