Answer:

Step-by-step explanation:
Given

Required
Determine the inverse function b(a)
Write A(b) as a

Swap a and b


Divide both sides by 7

Maka a the subject

Swap a and b again

Hence:

First, find the area of the whole square.
Area= Base times height= 48 times 96 = 4608
Next, find the area of ONE circle. The diameter is 12, so the radius would be 6
A=πr sqaured= 3.14 times 6 squared = 113.04
Next multiply by 3, since there are 3 circles.
113.04 times 3 =339.12
Subtract this value from the total area (4608)
4608-339.12=4268.88
ANSWER: 4268.88
-2x-3=-7
<em>add 3 to both sides</em>
-2x=-4
<em>isolate x by diving both sides by -2</em>
Answer: x=2

Answer:
5/9 m/min
Step-by-step explanation:
The depth of the water is 2/5 of the depth of the trough, so the width of the surface will be 2/5 of the width of the trough:
2/5 × 2 m = 4/5 m
Then the surface area of the water is ...
A = LW = (18 m)(4/5 m) = 14.4 m²
The rate of change of height multiplied by the area gives the rate of change of volume:
8 m³/min = (14.4 m²)(h')
h' = (8 m³/min)/(14.4 m²) = 5/9 m/min
