Answer:
A. 8 ft
B. 660 times
Step-by-step explanation:
A. Finding the circumference:
The formula for the circumference is
C = πD where D is the diameter
We are given D = 2.5, and to use π = 3.14, so plug those values in...
C = π(2.5) = (2.5)(3.14)
C = 7.85, which rounds to 8 (the nearest whole number)
B. How many times will it rotate in one mile.
Divide 5,280 by 8 to see how many times the tire will rotate (each time it rotates once the tire travels 8 ft)
5,280/8 = 660
2 over 3 plus 5 equals 5 and 2 over 3
Answer:
They can`t cross because the slopes are the same.
Since the first equation isn`t simplified, I`ll simplify it.
-x + 4y = -8
4y = x - 8
<u>y = x - 2</u>
After both are simplified, both slopes will be positive 1x. That means the lines are parallel and never cross. I`m sorry if this wasn`t much help, but that is the only answer I can think of. If there is not other option than placing a real answer, than I wouldn`t know how to solve this, sorry.
If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate
.
We have

Expand the numerator using the binomial theorem, then simplify and compute the limit.

In general, the derivative of a power function
is
. (This is the aptly-named "power rule" for differentiation.)
