A section of a water tube ride at an amusement park can be modelled by the function h(t)=−0.002t^4 +0.104t^3 −1.69t^2 +8.5t +9

where t is the time, in seconds, and h is the height, in metres, above the ground. When will the riders be more than 15 m above the ground?

d is the answer

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
