II. Ferris Wheel The height of a chair on a Ferris wheel follows the equation y =5.7sin(0.31x)+ 7.9 , where y is the height (in meters) and x is the time (in seconds). Where necessary round all answers to 2 decimal places
a) What is the maximum height the Ferris wheel reaches?
b) What is the minimum height the Ferris wheel reaches?
c) How long does it take the Ferris wheel to make 1 complete cycle?
d) How high is the Ferris wheel after 12.5 seconds?
e) In the during the first rotation of the Ferris wheel, at what time(s) does the it reach 10 m?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
