We have been given a parent function
and we need to transform this function into
.
We will be required to use three transformations to obtain the required function from
.
First transformation would be to shift the graph to the right by 4 units. Upon using this transformation, the function will change to
.
Second transformation would be to compress the graph vertically by half. Upon using the second transformation, the new function becomes
.
Third transformation would be to shift the graph upwards by 5 units. Upon using this last transformation, we get the new function as
.
Answer:
42.4
Step-by-step explanation:
1) use this formula of Area of the triangle:

2) using the formula described above:
A=0.5*14*11*0.55≈42.4 (mm²)
800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
