Answer:
A = 157 in^2
Step-by-step explanation:
First, we need to get the radius, we can do this by dividing our given diameter by 2.
20/2 = 10
Now, we have our radius of 10 inches.
Formula for Area of a Semi Circle: (1/2)(pi(r^2)
Input values.
(1/2)(3.14(10^2)
Solve.
(1/2)(3.14(100)
(1/2)(314)
1/2(314) = 157
Finally, we have our result which is 157 inches^2.
Answer:
Step-by-step explanation:
f(x) = (1/2) *6^x = 2^-1 * 2^x *3^x
y= 2^ (x-1) * 3^x
Domain represents all values that x can have and is all real numbers
Range all values that y can have and is y > 0 ( all real numbers that are positive)
The y-intercept is the point where the graph intersects the y-axis so x=0 there
y = 2^(0-1) *3^0 = 1/2 *1 = 1/2
the asymptote is at y= 0
Answer:
V = π × 4² × 16
Step-by-step explanation:
The formula for the volume of a cylinder is
V = πr²h
Data:
r = 4 in
h = 16 in
Calculation:
V = πr²h = π × 4² × 16
Slope = (Y2 -Y1) ÷ (X2 -X1)
Slope = (1 -7) / (10 -1)
Slope = -6 / 9 = -0.6666666666666666
The answer is going to be A.) -2
