Answer:
Correct option is (C).
Step-by-step explanation:
Because in figure,
°.°point B is fixed at plane.
.°.Center is B.
& °.° Image is enlargement.
.°. scale factor will be greater than 1
Now,
scale factor = A'B'/AB
= 24/6
= 3
So correct option is (C).

So, here we have an exponential function.
Remember that an exponential function has the form:
Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that
So,
For city B:
But something different happens with city C. This is not an exponential function, this is a linear function.
So,
Answer:
1. x=3
2. x=-8
3. x=-11
Step-by-step explanation:
Area of a rectangle: length x width
Therefore: 2 x 3 = 6
6ft^2
6ft = 72 inches
The area of the poster is 72in^2
x + (-13) = -5
x - 13 = -5
x = -5 + 13
<u>x</u><u> </u><u>=</u><u> </u><u>8</u>
