Step-by-step explanation:
I guess it means we need to calculate the height of the green dot on the bicycle wheel that moves as the wheel turns by a certain radial distance.
since the circumference of a circle is 2×pi×r, the circumference for a circle with radius = 1 is simply 2×pi (ft in this case).
pi/2 = 90° or a quarter rotation.
pi = 180° or a half rotation.
3×pi/2 = 270° or 3 quarter rotation.
2×pi = 360° or a full rotation.
the height starts at 6ft, and can go up 2 more ft (the diameter of the wheel) to 8 ft.
so, the table is
0 6
pi/2 7 (6+1)
pi 8 (6+2)
3×pi/2 7 (6+2-1)
2×pi 6 (6+2-2) back to the starting height
so,
a = 6
b = 7
c = 8
d = 7
e = 6
The other way is to use a very accurate ruler, and measure the
distance between the two points on the paper. Alternatively, if
you have it on the computer, you can blow up the image on the
screen and measure it very precisely.
If you don't want to measure it, and you want to use the coordinates
of the points to calculate it, then any method you use is going to boil
down to the Pythagorean Theorem.
Z= 9
U just divide one side by another where both numbers r in and u do the same with z
A=6d-g because to be able to get the 6 on the other side you have to multiply 6 on both sides. Then you would have to subtract g to get it on the other side. This causes the gs on the original side to eliminate
I found the exponential function.
C = 10.5(1.194)^t
The definition of an exponential function is this:
"If b is any number such that b > 0 and b ≠ 1 then an exponential function is a function in the form, f(x) = b^x , where b is called the base and x can be any real number"
Using the description, the answer is a.) B is 1.194 ; it is a growth factor.
B is identified as a growth factor because it is more than 1. If it had been less than 1, it would have been a decay factor.
