The surface area of hemisphere is given by:
Where r is radius of hemisphere.
We are given diameter = 250 ft.
We know that radius = half of diameter.
Radius of dome = 1/2 (250) = 125 ft.
Now let us plug the value of radius in the formula,
Surface Area of dome = 98125 square foot.
Answer:
B
Step-by-step explanation:
A square bracket means that the endpoint is included.
(f + g)(x) = (x + 4)^2 + 3
The range is the y value and the 3 is included. There is only 1 answer that shows that and that is B. The minimum value is 3 and it is included in the range.
The upper value of the range is undefined. It is not included in the value for the range. That leaves you with a round bracket for the upper value of the range. A compound statement of all of this is 3 ≤ y < ∞
The representation of the compound statement is B
Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15

Csc^2x-cot^2x=1
Here is why
csc^2x=1+cot^2x
so:
1+cot^2x-cot^2x=1
1=1
