Answer:
A = 80π
Step-by-step explanation:
Area of a circle is A = πr²
Area of the the largest circle - Area of the smaller circle = the shaded part.
Largest circle - Area of the smaller circle = Shaded part of circle
A = π(12)² - A = π(8)²
144π - 64π = 80π
X is any number smaller than 8, or X<8. A positive integer could be 7, 6, 5, 4, 3, 2, 1, or 0.
Answer:
B
Step-by-step explanation:
Each histogram section represents all values from the left value, to the right value of each section (i.e the section after 10 represents all values from 10 to 20).
If we break all the weights into categories by this principle, with frequencies in parenthesis, we get;
0-10: (0)
10-20: (0)
20-30: 21, 24 (2)
30-40: (0)
40-50: 42, 47 (2)
50-60: 54, 56 (2)
60-70: 65 (1)
70-80: 72 (1)
80-90: 83, 86 (2)
90-100: (0)
with these numbers, we know for certain that the correct answer is B
Answer:
Step-by-step explanation:
We have been given that a polynomial function 
models the motion of a roller coaster. Every root of the polynomial represent when the roller coaster is at the ground level.
In order to find all the potential values of x when roller coaster is at the ground level, we find the zeroes of the polynomial by factoring it as shown below:
The zeroes of this polynomial occur when either or 
.
The equation have no real solutions. Therefore, the only time when the roller coaster is at the ground is at
