ANSWER THIS AND GET A BRAINIEST . thank youu - 10 points
crimeas [40]

Answer:

18; 1h30m; 15

Step-by-step explanation:

<u>Part A:</u>

James traveled 45km, you can tell because that is where he stops.

It took him from 2pm to 4:30pm.

You can find this info on the x axis.

That means 45km took him 2.5 hours.

45/2.5=18

James travels 18km per hour.

<u>Part B:</u>

The stop is indicated by the flat part in the graph. This is because when he stops, the distance he is away from home is not changing.

His stop is from 4:30pm to 5pm.

This means that his stop is 1 hour and 30 minutes.

<u>Part C:</u>

James had to travel 45km to get back home. (45-0)

It took him from 5pm to 8pm.

This means that on his journey back, 45km took him 3 hours.

45/3=15

James travels 15km per hour.

The function h(t)=-4.87t^2+18.75t is used to model the height of an object projected in the air, where h(t) is the height in met
rodikova [14]
Looking at the graph you can see that the domain of the function is:
 [0, 3.85]
 To find the range of the function, we must follow the following steps:
 Step 1)
 
Evaluate for t = 0
 h (0) = - 4.87 (0) ^ 2 + 18.75 (0)
 h (0) = 0
 Step 2) 
 find the maximum of the function:
 h (t) = - 4.87t ^ 2 + 18.75t
 h '(t) = - 9.74 * t + 18.75
 -9.74 * t + 18.75 = 0
 t = 18.75 / 9.74
 t = 1.925051335
 We evaluate the function at its maximum point:
 h (1.925051335) = - 4.87 * (1.925051335) ^ 2 + 18.75 * (1.925051335)
 h (1.93) = 18.05
 The range of the function is:
 [0, 18.05]
 Answer:
 
Domain: [0, 3.85]
 Range: [0, 18.05]
