The average low temperature for January was 40 °F - 100%.
The average low in February was x °F - 27% lower, that is 100%-27%=73%.
Write a proportion:

Answer: the average low in February was 29.2 °F.

Determine the inequality of the region
The inequality of a region of a sphere is determined using:

Substitute 5 for r


Solving further: <em>The question says only the upper hemisphere is considered.</em>
This implies that:

<em>So, the equation is:</em>


Answer:
(i)
shifted left side by 5 units
(ii)
vertically stretch by 3 units
(iii)
shifted vertically downward by 2 units
Step-by-step explanation:
we are given

we can also write as

we can factor out 9

Firstly, we will identify parent function

step-1:
We can see that there is x+5 in place of x
so, f(x) will be shifted left side by 5 units
step-2:
3 is multiplied to sqrt
so, it is vertically stretch by 3 units
step-3:
-2 is added to y-value
so, it is shifted vertically downward by 2 units
