1. A~ 2r^2 + 15r-50
2. B~ k^2 - 4k+3
Answer:
y=1/7.50x+40
Step-by-step explanation:
I doubled checked myself on desmos and it worked. You start at 40$ because you pay that no matter what. For each one they buy the price goes up by 7.50$.
You could use sine to find it
sin45 = 8/m
m = 8/sin45
The temperature rose, which means it increased. An increase is a positive value, so add a plus sign in front of the number: +4
A decrease is a negative value, so add a negative sign in front of the value: -19
Answer:
.88
Step-by-step explanation:
We can use this equation:
Where:
- N is the increase factor (N=512)
- R is the reduce factor (R=8)
- D is the dimension
We just need to solve it for D
.88
Therefore the dimension will be 3
I hope it helps you!
