Answer:
19.625 feet²
Step-by-step explanation:
Max diameter = 5 feet
Radius = 2.5 feet
Area = 3.14×2.5² = 19.625 feet²
P(-2) = a*(-2)^3 = -8*a, right? :) Then -8*a=64==> a = 64/(-8)=-8. So, the last one!
Answer:
3/1 is the <u>ans</u>
Step-by-step explanation:
here y is in 3
and x is in 1
so proportonality will be 3/1
The two lines will intersect at the point (2, 3).
We can find this by setting the two equations equal to eachother, as the point at which they intersect is the point where they share the same x and y value. First, we have to get both equations in the form y = mx + c, so:
-x - y = -5
+ y
-x = -5 + y
+ 5
y = -x + 5
Now we can set -x + 5 equal to x + 1 and solve to find the x coordinate:
-x + 5 = x + 1
+ x
5 = 2x + 1
- 1
4 = 2x
÷ 2
2 = x
With the x coordinate, we can substitute it in to one of the equations and find our y coordinate:
y = 2 + 1 = 3
So the final answer is (2, 3).
I hope this helps!
-x + 5 = x + 1
