Answer:
Step-by-step explanation:
Given
At maximum height
Required
Select which of the options is true
At the maximum height of an upward projectile, the final velocity (v) is always equal to 0.
i.e.
Other parameters such as initial velocity (u), acceleration (a or g) are not 0.
Hence:
(c) answers the question
Given:
The vertex of a triangle MNP are M(-4, 6), N(2, 6), and P(-1, 1).
The rule of dilation is:
The image of triangle MNP after dilation is M'N'P'.
To find:
The coordinates of the endpoints of segment M'N'.
Solution:
The end points of MN are M(-4, 6) and N(2, 6).
The rule of dilation is:
Using this rule, we get
And,
The endpoints of M'N' are M'(-6, 9) and N'(3, 9).
Therefore, the correct option is B.
Answer: The required solution is
Step-by-step explanation:
We are given to solve the following differential equation :
where k is a constant and the equation satisfies the conditions y(0) = 50, y(5) = 100.
From equation (i), we have
Integrating both sides, we get
Also, the conditions are
and
Thus, the required solution is
