Answer:
a) Find the value of the function when x = -2
b) we get f(-2)=65
Step-by-step explanation:
We are given the function f(x)=6(8-x)+5
a) What does the notation f(-2) mean?
The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x = -2
b) What is the value of f(-2) ?
We need to find the value of f(-2)

Put x = -2

So, we get f(-2)=65
Add 3 and 9 together divided by 2 ....u should get 6
Answer:
49.132 m²
Step-by-step explanation:
Area of a triangle=1/2(base×height)
Area=1/2(6×8)
Area=24 m²
Now
Area of semi circle=πr²/2
Area=(3.14)(8÷2)²/2
Area=(3.14)(4)²/2
Area=(3.14)(16)/2
Area=50.265/2
Area=25.132 m²
Now
Total area=area of triangle+semi-circle
Total area=24+25.132
Total area=49.132 m²
Answer:
216 cm^2
Step-by-step explanation:
Alright, first lets knock out the rectangle. This would be found by doing L * H. For the length it would be 14. For the height, it would be 12.
14 * 12 = 168
Next with the triangle, it has a length, or "base" of 8 and the same height of 12. For a triangle, do (B * H) / 2 as the formula.
(8 * 12) / 2
96 / 2
48
Now, combine these two values to get the total:
168 + 48 = 216 cm^2
All done!
