The height of an acrobat who jumps from a trampoline to a large mat on the ground can be modeled by f(x)=-8x^2+16x+10, where x is the time in seconds after the acrobat jumps.

How high is the trampoline off the ground?

Find the maximum height of the acrobat and the time it takes to reach this height.

what about the answer with the numbers y=16x^2+20x+4?

Is it:

A. The function is linear

B. The function is linear at some points and nonlinear at other points

C. Not enough info given to decide

D. The function is nonlinear

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
