Suppose that you want to model the height of a rider on a Ferris wheel as a function of time. The amplitude of the function you use as a model should be equal to which of the following?a. the area of the Ferris wheel
b. the circumference of the Ferris wheel
c. the diameter of the Ferris wheel
d. the radius of the Ferris wheel
Answers
Answer: d. the radius of the Ferris wheel
Step-by-step explanation:
We now that the amplitude is the vertical distance between a peak or a valley and the equilibrium point.
Thus in the case of Ferris wheel the amplitude should be the difference between the peak(highest) and equilibrium point or equillibrium point and valley(lowest) points .
i.e. it should be half of the diameter of the circle. Since half of diameter of a circle is equals to radius.
Therefore, the amplitude of the function you use as a model should be equal to the radius of the Ferris wheel.

Answer:
B. The axis of symmetry is x=1.
F. The vertex is (1, 7).
G. The y-intercept is (0, 10).
Step-by-step explanation:
A graph of the function is helpful sorting this out.
_____
For quadratic ax² +bx +c, the axis of symmetry is x=-b/(2a). Here, that is ...
x = -(-6)/(2·3)
x = 1 . . . . axis of symmetry
This is also the x-coordinate of the vertex. The y-coordinate of the vertex can be found by evaluating the expression for this value of x:
3·1² -6·1 +10 = 7
so the vertex is (1, 7).
__
The y-intercept is the constant, the value of the function when x=0. Here, that is 10, so the coordinates of the y-intercept are (0, 10).

If the jar has $1.55 worth of dimes and nickels in a jar. There are 23 coins in the jar then there are 8 dimes and 15 nickels in the jar.
The total value of dimes and nickels in the jar is $1.55.
There are 23 coins in the jar.
d + n = 23 ...(1)
The total value of dimes and nickels is $1.55
0.10d + 0.05n = 1.55 ..(2)
Now, we need to solve this system of equations to find the values of "d" and "n."
We can use substitution or elimination method to solve it. Let's use the substitution method:
From Equation 1, we can rewrite it as: d = 23 - n
Now, substitute this value of "d" in Equation 2:
0.10(23 - n) + 0.05n = 1.55
2.30 - 0.10n + 0.05n = 1.55
Combine like terms:
-0.05n = 1.55 - 2.30
-0.05n = -0.75
Now, divide by -0.05:
n = -0.75 / -0.05
n = 15
Now that we have the value of "n" (nickels), we can find the value of "d" (dimes) from Equation 1:
d = 23 - n
d = 23 - 15
d = 8
Hence, there are 8 dimes and 15 nickels in the jar.
