Answer:The value of the expression increases as r decreases.
Step-by-step explanation:
To find : What happens to the value of the expression as r decreases?
Given Expression: 80-2r
We check for different value of r as decreasing order,
r 80-2r
5 80-10=70
4 80-8=72
3 80-6=74
2 80-4=76
1 80-2=78
As r decreases the value of expression increases.
Therefore, the value of the expression increases as r decreases.
Hope this helps!
Answer:
32 and 56?
Step-by-step explanation:
32 and 56 are related to 8.
32=8x4
56=8x7
A. x=3/2
D. x=1/2
Solve for x over the real numbers:
4 x^2 - 8 x + 3 = 0
The left hand side factors into a product with two terms:
(2 x - 3) (2 x - 1) = 0
Split into two equations:
2 x - 3 = 0 or 2 x - 1 = 0
Add 3 to both sides:
2 x = 3 or 2 x - 1 = 0
Divide both sides by 2:
x = 3/2 or 2 x - 1 = 0
Add 1 to both sides:
x = 3/2 or 2 x = 1
Divide both sides by 2:
Answer: x = 3/2 or x = 1/2
Answer:
- 3
Step-by-step explanation:
Using the law of logarithms
x = n ⇔ x = 
let
(
) = n
(
) = n, then
= 
Since bases are the same on both sides then equate the exponents
⇒ n = - 3 → (4)
Area = 200.96 cm^2
r = square root of area / 3.14
radius r = 7.9967778595084
