Answer:

<h2>The temperature remains constant from 11AM to 2PM.</h2>

Step-by-step explanation:

When we study a piecewise function, it's characterized by having different behaviours in its intervals.

In this case, the function is linear in every interval given. So, when the line is upwards, it meas the function is increasing. In this case increases from the beginning to 11AM.

Then, the function has a horizontal line, which means there's no change at all in the temperature from 11AM to 2PM. In other words, the temperature is constant during this time, because the line is horizontal.

At last, the temperature decreases, because it has a line that is going down.

Therefore, according to the graph, the temperature remains constant from 11AM to 2PM.

Maria's height while jumping on a a trampoline can be modeled by the equation h=-16t^2+18t+5. Where t=time in seconds and h=heig

Vadim26 [7]

Answer:

10.06 ft

Step-by-step explanation:

Maria's maximum height will occur when her velocity reaches zero (0). This means that she has stopped ascending and is about to begin descent.

The equation for the height reached by Maria on the trampoline is given as:

$h=-16t^2+18t+5$

To find her maximum height, we first have to find the time it will take her to get to that height and corresponding velocity (zero).

Her velocity can be found by differentiating her height i.e. dh/dt:

$v = \frac{dh}{dt} = -32t + 18$

Therefore, when v = 0:

$0 = -32t+ 18\\\\=> 32t= 18\\\\t = 18 / 32 = 0.5625 secs$

It takes her 0.5625 seconds to get to her maximum height.

Therefore, her height at that time (0.5625 seconds) is:

$h=-16(0.5625)^2+18(0.5625)+5\\\\h = -16 * (0.3164) + 10.125+5\\\\h = -5.0624 + 15.125\\\\h = 10.06 ft$

Therefore, her maximum height is 10.06 ft.
