Answer: The area is approximately 314 ft^2
Step-by-step explanation:
Well if the diameter is 20 feet then the radius will be 10 because the radius is half the diameter, and to find the area of a circle, you use the formula
A= where A is the area and pi times the radius squared.
We will represent pi by 3.14
A= 3.14* 10^2
A= 3.14 * 100
A = 314

Answer:
d. -4.4
Step-by-step explanation:
We know that log (a/b) = log a - log b
Since log a = 1.2 and log b = 5.6 , we can substitute these values into the equation.
log (a/b) = 1.2 - 5.6
= -4.4
Answer:
y = -3x + 8
Step-by-step explanation:
First, find the slope of the equation.
delta y/ delta x = (-4-11)/(4-(-1)) --> -15/5
The slope is -3
y = -3x + b
To find b, input the values of one of the ordered pairs
Using (4,-4) :
-4 = -3(4) + b
-4 = -12 + b
8 = b
The final equation is y = -3x + 8
