. Correct option is D) 113.0 ft² .
<u>Step-by-step explanation:</u>
Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:
We know that area of circle = , We have following parameters as
So , Area of circle is
⇒
⇒
⇒
⇒
On Rounding off
⇒
Therefore , . Correct option is D) 113.0 ft² .
<u>Answer:</u>
Initial value: 250
Decay
Decay rate: 11%
Initial value: 40
Growth
Growth rate: 11%
<u>Step-by-step explanation:</u>
The function we have on the left of the table is:
<u>Initial value</u> (when x = 0):
y = 250 (initial value)
Growth or Decay: 0.89 < 1 so decay
Decay rate: (1 - 0.89) * 100 = 11%
Function on right side:
<u>Initial value</u> (when x = 0):
y = 40 (initial value)
Growth or decay: 1.11 > 1 so growth
Growth rate: (1.11 - 1) * 100 = 11%
Answer:
(-1,-1)
Step-by-step explanation:
finding y
-6x + 5y = 1
+ (6x + 4y = -10)
---------------------------
9y = -9
y = -1
finding x
-6x + 5(-1) = 1
-6x - 5 = 1
+ 5 = +5
-6x = 6
x= -1
