When you board a Ferris wheel moving counter-clockwise at a constant rate, your feet are 5 feet off the ground. At the highest point of the ride, your feet are 65 feet above the ground. It takes 120 seconds for the ride to complete one full revolution. Select the correct options that create the correct function to model this situation, where t is time elapsed in seconds since you got on and his height above the ground in feet. h(t) = d ta sin or cos) (bt) d = [ Select] + [ Select] [ Select] a sin or cos == [ Select] [ Select]​

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
