Answer:
Option D.
Step-by-step explanation:
The area of the circular bases is:
Where
is the radius of the circle
Then
The area of the rectangle is:
Where
b is the width of the rectangle and 
is the length
Then the area of the rectangle is:
Finally the total area is:
2nd one is the correct one I think
Answer:
-9
Step-by-step explanation:
you'd add 2 to the -11 which would equal -9 and leave you with x=-9
When we have two arcs in a circle, one larger and one smaller, one will be called the minor arc and the other the minor arc.
The name of the arc depends on its size, for example, given the following green and yellow arcs, the green, which is smaller, will be the minor arc:
Therefore, the larger arc is always called Major arc, not minor arc.
The statement is False.
Answer: False
Answer:
x = 11, -1
Step-by-step explanation:
First, let's identify what the quadratic formula is:
x = [-b ± √(b² - 4(a)(c))] / 2
Our equation is written in standard form:
ax² + bx + c = 0
x² - 10x - 11 = 0
Let's plug in what we know.
x = [-(-10) ± √((-10)² - 4(1)(-11))] / 2
Evaluate the exponent.
x = [-(-10) ± √(100 - 4(1)(-11))] / 2
Simplify the negatives.
x = [10 ± √(100 - 4(1)(-11))] / 2
Multiply.
x = [10 ± √(100 + 44)] / 2
Simplify the parentheses.
x = [10 ± √(144)] / 2
Simplify the radical (√)
x = [10 ± 12] / 2
Evaluate the ±.
x = [10 + 12] / 2
x = [22] / 2
x = 11
or
x = [10 - 12] / 2
x = [-2] / 2
x = -1
Your answers are x = 11, -1
Hope this helps!
