Answer:
Step-by-step explanation:
Alright, lets get started.
Lets split the given graph in three parts.
First part: 0 to 30 minutes
We can see between this period, 0 to 30 minutes, the distance from home keeps increasing. It means from 0 to 30 minutes, Eli is moving towards the library.
Second part: 30 to 120 minutes
between 30 to 120 minutes,the distance from home does not changes. It means during this period, Eli is at the library.
Third part : 120 minutes to 135 minutes
Between 120 to 135 minutes, the distance from home is decreasing.
It means Eli is returning home in that period.
It means, at 120minute, Eli started her bicycle , home from the library. Hence option (b) : Answer
Hope it will help :)
F (x) = 5(4) ^x Is the right answer
Answer:
The resulting three-dimensional object will be a cone
Step-by-step explanation:
Plot the figure to better understand the problem'
we have
a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1)
The draw in the attached figure
we know that
When rotating a a right triangle about a leg, the three dimensional figure formed is a cone
The radius of the cone will be equal to the base of right triangle and the height of the cone will be equal to the height of the triangle
so
The radius of the cone will be equal to 2 units and the height of the cone will be 3 units
see the attached figure to better understand the problem
Answer:
Step-by-step explanation:
d(t)=-2t^2+9t+18
calculate the derivate : f'(t) = - 4t+9
f'(t) = 0 : - 4t+9= 0 so t = 9/4
the maximum value is f(9/4) = ....... continue
Answer:
y = -x + 4
Step-by-step explanation:
y + 2 = -x - 1
y = - x - 1 - 2
y = -x - 3
Point: (-2,6)
Slope -1
y-intercept: 6 - (-1)(-2)
= 6- 2 = 4
