Answer:
x = -2
Step-by-step explanation:
you have to multiply to remove the fraction, then set equal to 0
and solve.
<u>Given:</u>
The given function is 
We need to determine the reflection of f(x) over the x - axis
<u>Reflection over x - axis:</u>
The translation rule to reflect over the x - axis is given by
Reflecting the function over the x - axis, we get;
Multiplying -1 to both sides of the equation, we have;
This can be written as
Hence, the reflection of the function over the x - axis is
Thus, Option A is the correct answer.
I know that just the answer is not enough. You need to understand why and how. So I will explaing the steps.
First you need to state the equation that represents the function.
Investment is $200 and interest rate is 5%, y is the amount of money after x periods.
Note that after 1 period the amount of money is 200 plus 5% interest, which is 200 + 5%(200) = 200 (1 +5%) = 200 (1 + 0.05) = 200 (1.05)
After 2 periods the amount is 200(1.05)*(1.05) = 200 (1.05)^2
After 3 periods the amount is 200 (1.05)^3
And now you can deduce that after x periods y = 200 (1.05)^x
You can then analyze the function to predict the shape and critical points of the graph.
The answers are based in the initial value and the increasing factor.
The initial value is when x = 0, which yields to y = 200 (1.05)^0 = 200*1 = 200
And the increasing factor is 1.05 because any value is the previos one times 1.05.
Then the answer is the first option. The initial value is 200 and the graph increases by a factor of 1.05 per 1 unit increase in time.
Answer:
The answer to your question is Area = 50.27 m²
Step-by-step explanation:
Data
Area = ?
Diameter = 8 m
π = 3.1416
Formula
Area = πr²
Process
1.- Find the length of the radius
radius = diameter/2
- Substitution
radius = 8/2
- Result
radius = 4 m
2.- Find the area of the circle
Area = (3.1416) (4)²
Simplification and result
Area = (3.1416) (16)
Area = 50.27 m²
