Answer:
7. A = π
8. A = 6.25π
9. A = 16π
Step-by-step explanation:
When you have a bunch of similar problems that all use the same formula, it is usually convenient to solve the problem in generic terms, then put in the specific numbers.
You are asked to find A, and you are given the formula ...
To rewrite this as an equation for A, you divide by its coefficient, 4π.
If you like, you can go one step further, replacing C with kπ. Now, you have ...
__
7. k=2, A=(2^2)/4·π
A = π
__
8. k=5, A=(5^2)/4·π
A = (25/4)π
A = 6.25π
__
9. k=8, A=(8^2)/4·π
A = 16π
Answer: d. The vertical scale is too narrow. It needs to be a wider range, such as 0 to 100.
Step-by-step explanation:
The vertical scale is indeed too narrow. It needs to have a wider range that will enable a person who is looking at the graph, better compare the results shown because the magnitude of the number will be more apparent.
A range such as 0 to 100 would be ideal for this and would present the information in such a way that when a person looks at the graph, they understand the relative difference between the percentages who agreed with the court decision.
Answer:
Step-by-step explanation:
f(x) = 2x + 5
f(-6)= 2(-6) + 5 = -12 + 5 = -7
