Answer:

x = 6

Step-by-step explanation:

Givens

There are 3 sides. All are equal to (4x - 3)

Their sum = 63

Formula

3(4x - 3) = 63

Solution

3(4x - 3) = 63 Divide by 3
12x - 9 = 63 Add 9 to both sides
12x = 63 + 9
12x = 72 Divide by 12
x = 72/12

x = 6 Answer

The distance from the ground of a person riding on a Ferris wheel can be modeled by the equation d equals 20 times the sine of t

kodGreya [7K]

We have the function d, representing the distance from the ground of a person riding on a Ferris wheel:

$d(t)=20\sin (\frac{\pi}{30}t)+10$

If we consider the position of the person at t = 0, which is:

$d(0)=20\sin (\frac{\pi}{30}\cdot0)+10=20\cdot0+10=10$

This position, for t = 0, will be the same position as when the argument of the sine function is equal to 2π, which is equivalent to one cycle of the wheel. Then, we can find the value of t:

$\begin{gathered} \sin (\frac{\pi}{30}t)=\sin (2\pi) \\ \frac{\pi}{30}\cdot t=2\pi \\ t=2\pi\cdot\frac{30}{\pi} \\ t=60 \end{gathered}$

Then, the wheel will repeat its position after t = 60 seconds.

Answer: 60 seconds.

Reflection over the x-axis, vertical shift scale factor 3, horizontal translation LEFT 3 units(opposite since there are parenthesis), vertical translation down 7 units.
