-70
Some actually if it were y=mx+b then it would be the opposite. It would turn positive but I don’t think this one turns like that. I think it’s just -70
Answer:
A 4955.30
Step-by-step explanation:
A = P ( 1+i) ^ t
where A is the amount in the account
P is the principal
i is the interest rate
and t is the time in years
A = 4000(1+.055)^4
A = 4000(1.055)^4
A = 4955.2986025
Rounding to the nearest cent
A = 4955.30
Answer:
![A = \frac{r}{2}C](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Br%7D%7B2%7DC)
Step-by-step explanation:
Given
Shape: Circle
Required
The area and the circumference (relationship)
This implies that, we write an expression that relates the area and the circumference.
Circumference is calculated as:
![C = 2\pi r](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r)
Area is calculated as:
![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2)
The area can be rewritten as:
![A = \frac{2\pi r^2}{2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B2%5Cpi%20r%5E2%7D%7B2%7D)
Further rewrite as:
![A = \frac{r}{2}*2\pi r](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Br%7D%7B2%7D%2A2%5Cpi%20r)
Recall that:![C = 2\pi r](https://tex.z-dn.net/?f=C%20%3D%202%5Cpi%20r)
So, the expression becomes
![A = \frac{r}{2}*C](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Br%7D%7B2%7D%2AC)
![A = \frac{r}{2}C](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7Br%7D%7B2%7DC)
The slope goes downwards and that means its a negative slope.
slope means rises over run. and with the facts that we know, it gives us m=-15/24
