A Ferris wheel rotates around in 30 seconds. The maximum height above the ground is 55 feet, and the minimum height above the ground is 5 feet. Which function models the height as a function of t in
seconds?
f(t) = 25 sin 15 + + 30
f(t) = 25 sin 2t +30
f(t)
25 sin 60x + 30
f(t) = 30 sin it + 25

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

he kicked it up? is this the answer ?

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
