If d = 20 and C = 20π, then r = 10.
If d = 26 and C = 26π, <span>then r = 13.
</span>If r = 1/2 and C = π, <span>then d = 1.
</span>If r = 7 and C = 14π, <span>then d = 14.
</span>If r = 6 and C = 12π, <span>then d = 12.
</span>If r = 50 and C = 100π, then d = 100.
*Note, r= 1/2×d or d=2×r
Answer:
Step-by-step explanation:
Anything going from lower left to upper right is a positive slope.
The lines are not easily seen. My best estimate is that one point is (2,5)
Use the two points you are sure of.
(0,-1) and (1,2)
Givens
- x1 = 0
- x2 = 1
- y1 = - 1
- y2 = 2
Formula
m = (y2 - y1)/(x2 - x1)
Solution
m = (2 - - 1) / (1 - 0)
m = 3/1
m = 3
Answer:
1 < x < 4 . . . . {x | x < 4 <u>and</u> x > 1}
Step-by-step explanation:
We want to write the answer as a compound inequality, if possible. As it is written, we can solve each separately.
x + 1 < 5
x < 4 . . . . . . . subtract 1
__
x -4 > -3
x > 1 . . . . . . . add 4
So, the solution is ...
(x < 4) ∩ (x > 1) . . . . . . the intersection of the two solutions
As a compound inequality, this is written ...
1 < x < 4
