Answer:
1. 1800 square cm.
2. See below
3. 45000 square cm.
Explanation:
Part 1
The dimensions of the drawing are 36cm by 50cm.

Part 2
Given a scale factor, k
If the area of the scale drawing is A; then we can find the area of the actual board by multiplying the area of the scale drawing by the square of k.
Part 3

Therefore, the area of the actual drawing will be:
A: -15/5 degrees Celsius
B: -15/5=3 degree Celsius
every 5 weeks it change -15°c
so each week it changes -3°c
Answer:
option C is best.
Step-by-step explanation:
y=a(x-h)^2+k
y-k=a(x-h)^2y
y-k/(x-h)^2=a
C because the most shown value is 24
