Step-by-step explanation:
Answer:
B
r=9.7
C=60.95
Step-by-step explanation:
Given diameter of 19.4
r = d/2
19.4/2
r=9.7
C= 2(pi)r
2(pi)(9.7)
60.95 = C
Answer:
2,880 people
Step-by-step explanation:
Week 1: 3,000 cases
Week 2: 0.4 * 3,000 = 1,200. 1,200 + 3,000 = 4,200
Week 3: 0.4 * 4,200 = 1,680. 1,680 + 4,200 = 5,880
5,880 - 3,000 = 2,880
Answer:
The height of the new cones will be 16.5 inches.
Step-by-step explanation:
We know that,
The volume of a cone is,
Where, r is the radius of the cone,
h is the height of the cone,
In the original cone,
r = 22 inches,
h = 66 inches,
Thus, the volume would be,
Also, for the new cone,
r = 44 inches,
Let H be the height,
So, the volume of the new cone would be,
According to the question,
Hence, the height of the new cones will be 16.5 inches.
We will find the inverse of the given functions:
y = x + 2 / x-2
(x-2) y = x + 2
-2y + xy = x + 2
-2y + xy = x + 2
x (y - 1) = 2 + 2y
x (y - 1) = 2 (y + 1)
x = 2 (y + 1) / (y - 1)
f (x) ^ - 1 = 2 (x + 1) / (x - 1)
The inverse is different.
f (x) = x + 1 / x-1
y = x + 1 / x-1
(x-1) y = x + 1
-y + xy = x + 1
x (y - 1) = 1 + y
x (y - 1) = (y + 1)
x = (y + 1) / (y - 1)
f (x) ^ - 1 = (x + 1) / (x - 1)
The inverse is the same.
Answer:
f (x) = x + 1 / x-1
f (x) ^ - 1 = (x + 1) / (x - 1)
f (x) = f (x) ^ - 1
