Answer:
2nd graph above the one you chose
Answer:
<em>The answer is (B).</em>
Step-by-step explanation:
A). y = f(x) = 6(x - 2) + 3 ⇔ y = 6x - 12 + 3 ⇔ 6x = y + 9 ⇔ x =
g(x) =
is inverse function of f(x) and ≠
- 3
<em>B).</em> y = f(x) =
- 3 ⇔ 4y = 5x - 12 ⇔ x =
g(x) =
is inverse of f(x)

Exact Area = 1200 - 300pi square cm</h3><h3>
Approximate Area = 257.522203923062 square cm</h3>
Work Shown:
The area of the rectangle is 40*30 = 1200 square cm
Note how we have 4 circles along the horizontal dimension which is 40 cm, so each diameter is 40/4 = 10 cm, and the radius is 10/2 = 5 cm
Each circle has an area of pi*r^2 = pi*5^2 = 25pi
There are 4*3 = 12 circles, so the circle areas combine to 12*25pi = 300pi
Using a calculator, we find that 1200 - 300pi = 257.522203923062 approximately. Round this however you need to.
<D = 180 - <B - <C
<D = 180 - 83 - 42
<D = 55
answer
C. 55
The formula to working out the exterior angle of a polygon is this:
360 divided / (number of sides)
So, let’s use this formula to work out the answer.
360 / 7 = 51.4 to the nearest decimal place
