Answer: 1008 revolutions
Step-by-step explanation:
1 revolution is equal to
To find how many revolutions the wheel makes, you must divide the distance traveled in the race between the circumference of the wheel
You must first convert 62.8318 in to meters.
We know that 1 inch is 0.0254 meters
Then
Finally The wheel made 1008.21 revolutions
Answer:
The red line is g(x)
Step-by-step explanation:
* To solve this problem you must to know some fact about
transformation
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
- A vertical stretching is the stretching of the graph away from
the x-axis
• if k > 1, the graph of y = k•f (x) is the graph of f (x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each of its y-coordinates by k.
• if k should be negative, the vertical stretch or compress is
followed by a reflection across the x-axis.
* Now lets solve the problem
- g(x) = -1/2f(x + 2)
# x + 2 ⇒ means the graph moved 2 units to the left
# -1/2 ⇒ means the graph has vertical compressed followed
by a reflection across the x-axis, then multiply
each y-coordinate by -1/2
- The graph of f(x) intersects x-axis at point (3 , 0)
∴ The point will be (1 , 0) on g(x)
- The graph of f(x) intersects y-axis at point (0 , -6)
∴ The point will be (-2 , 3) on g(x)
* Look to the graph
# The red line is g(x)
# The blue line is f(x)
- To check your answer
# The equation of f(x) is f(x) = 2x - 6
∵ g(x) = -1/2f(x + 2)
∴ g(x) = -1/2[2(x + 2) - 6] = -1/2[2x + 4 - 6] = -1/2[2x - 2] = -x + 1
* g(x) intersect x-axis at point (1 , 0) and y-axis at point (0 , 1)
