Let, the total number of students in school that ride the bike to school be "x"
Now,
Using ratio and proportion, we get,
So, out of 800 students, 125 ride their bike to school.
Answer:
the value of x is 12, the answer is C, x = 12
Answer:
To create function h, function f was translated 2 units to the right, translated 4 units down and reflected across the y-axis.
Step-by-step explanation:
Since f(x) = x^3 is transformed to h(x) = -(x+2)^3-4, by
1. Adding 2 to x in x³ to give f'(x) = f(x + 2) = (x + 2)³.
2. We now translate f(x + 2) down by subtracting 4 from f(x + 2) to give
f''(x) = f'(x) - 4 = f(x +2) - 4 = (x + 2)³ - 4.
3. We now reflect f'(x) across the y-axis by multiplying (x + 2)³ by -1 to get
h(x) = -(x + 2)³ - 4.
28 + (3x -2) + 28 = 6x
28+ (3x -3x -2) + 28 = 6x - 3x
28+ (-2) + 28 = 3x
28 - 2 + 28 = 3x
26 + 28 = 3x
54 = 3x
18 = x
C) 12pi
Circumference is pi x diameter or 2 x pi x radius
