The answer is B because scientific notation always has the decimal point after the first digit from the left and the power is always the number of decimal places between where the decimal originally is (in this case the very end) and where you place it.
Answer:
600 m
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m.
Since the tires revolve 15 times per second, this means every second the tires travel 15 m.
This means that in 40 seconds, the tires travel
15(40) = 600 m.
Answer:
d) 100 feet
Step-by-step explanation:
The x value of the vertex (highest point in this case) is found via -b/2a:
-80/-32 = 2.5
Plug 2.5 into the function:
h(2.5) = -16(2.5)² + 80(2.5)
= - 100 + 200 = 100
I don't have a lot of experience with chance, but there are 2 odd numbers before 4, 1 and 3, so it would be 2 out of 6 or 33.3 continuing percent.
