Answer:
1
Step-by-step explanation:
Slope = Change in y/ Change in x
= (9-7)/(9-7)
= 2/2
Please, use the symbol " ^ " to denote exponentiation. At first I had no idea what you meant by 3r2.
You are using the approx. formula A = 3 r^2 to find the area.
The given radius is 4.3 inches. Subst. this value for r in the above equation.
Find A (keeping in mind that it's an approximation).
Answer:
Step-by-step explanation:
Answer:
false because you would multiply 5×the number of options so 5×4=20
Answer:
The relationship B is different than the other three, because it has a different proportionality constant.
Step-by-step explanation:
All available options show direct relationships, which are defined as follows:

(1)
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Proportionality constant, dimensionless.
We proceed to use the following strategy based on the proportionality constant, that is:

A different relationship must indicate a different proportionality constant:
Option A (
,
)


Option B (
,
)


Option C (
,
)


Option D (
,
)


The relationship B is different than the other three, because it has a different proportionality constant.
