A Ferris wheel has a diameter of 56 ft. how far will a rider travel during a 4-minute ride if the wheel rotates once every 20 se
Luba_88 [7]
First calculate the circumference. Usually this is the diameter times pi, but since we are told to estimate pi, the circumference equals 56 * 22/7 or 176 feet.
In 4 minutes, 4 * 60 = 240 seconds pass. In this time, a 20 second period will occur 240/20 = 12 times.
So we know that the rider rotates 12 times and each rotation takes them 176 feet, meaning that they will travel 12 * 176 =  2112 feet

dezoksy [38]
If D is the midpoint of GH, then GH equals 2(DH) = 16
16 = 4x - 1
4x = 17
x = 17/4

Which is the same as adding a number to itself?
tankabanditka [31]

Answer:

Multiplication with 2.

Step-by-step explanation:

In this question, we have to find the operation which is equivalent to adding a number to itself.

The operation is multiplication with 2.

If a number is multiplied with 2, then the operation is equivalent to adding a number to itself.

For example, if you multiply the number x with 2, the result is 2x and again if you add x with x, you will get the same result as 2x. (Answer)

What the domain and range is for the function f(x) = x2 + 4x - 21.
prisoha [69]

Answer:

Step-by-step explanation:

Please use " ^ " to denote exponentiation:  f(x) = x^2 + 4x - 21.

This function has a graph which is a parabola that opens up.

Its vertex is found by completing the square:

x² + 4x + 4 - 4 - 21, or

 (x + 2)² - 25

Comparing this to the standard equation

 (x - h)² + k, we see that h = -2 and k = -25.

Thus, the vertex (and the minimum of this function) is (-2, -25).

Thus, the range is [-25, ∞ ).  This being a polynomial function, it has no restrictions on the domain:  the domain is (-∞, ∞ )
