This should be simple, add the Amounts of snow for the first week
4.32 + 6.86 = 11.18
-------------------------------------------------------
The subtract the amounts of snow from each week
11.18 - 7.89 = 3.29
----------------------------------------
C.) 3.29 is your answer
Dilation involves changing the size of a shape
<h3>How to determine the relationship between the trigonometry ratios</h3>
From the question, we understand that:
The dilation of triangle XYZ gives triangle ACB
This means that, the following are corresponding points
- Points X and A
- Points Y and C
- Points Z and B
The above means that:
The relationships between the trigonometry ratios of both triangles are:
cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>How to determine the measures of segments AC and AB</h3>
In (a), segments XY and XZ corresponds to the segments AC and AB
So, the product of the lengths of XY and XZ and the scale factor will result in the lengths of AC and AB,
i.e.
AC = 2 * XY and AB = 2 * XZ

The given equation is 
where h is the height, in feet, of a ball and t is the time, in seconds.
<u>Part a: The height of the ball when t = 2 seconds:</u>
The height of the ball above the ground 2 seconds after it is released can be determined by substituting t= 2 in the equation , we get;
Simplifying the terms, we get;
Thus, the height of the ball after 2 seconds is 100 feet.
<u>Part b: The height of the ball when t = 4 seconds:</u>
The height of the ball above the ground 4 seconds after it is released can be determined by substituting t = 4 in the equation , we get;
Simplifying the terms, we get;
Thus, the height of the ball after 4 seconds is 68 feet.
