In one revolution of the wheel, a point on the edge travels a distance equal to the circumference of the wheel.
The wheel has radius 1 ft, so its circumference is 2π (1 ft) = 2π ft.
Then the point has a linear speed of
(1/4 rev/s) * (2π ft/rev) = 2π/4 ft/s = π/2 ft/s
We are given the following inequality:
If we replace b = 2, we get:
Now we solve for "a" first by subtracting 8 on both sides:
Now we divide both sides by 6
Simplifying:
Therefore, for b = 2, the possible values of "a" are those that are greater than 1/3
Answer:
There are 8 boys for every 10 girls. This is 6 equal groups. Equal ratio
Step-by-step explanation:
Answer:
The answer is (h).
Step-by-step explanation:
When y = 2^x is shifted 4 units left, the x shifts 4 units to the left and x becomes (x+4). When the graph is shifted to units down, y has to be subtracted by 2.
The function becomes
y = 2^(x+4) -2.
Finally, you shift -2 to the same side as y.
This becomes
y+2 = 2^(x+4) which is (h)
