Answer:
45.8
Step-by-step explanation:
We need to find the surface area for this entire figure!
We can see that this is a pyramid here - we must find the area of the 3 triangles and the base triangle at the bottom.
The 3 triangles building up the pyramid are all equal to each other.
To find the area of a triangle, use 

Round to the nearest tenth: 45.75 -> 45.8
Answer:
x = 3.7
Step-by-step explanation:
Apply trigonometric function to find x
Reference angle = 24°
Opposite = x
Hypotenuse = 9
This, apply SOH:
Sin 24 = Opp/Hyp
Sin 24 = x/9
9 × Sin 24 = x
3.66062979 = x
x = 3.7 (nearest tenth)

1)
f (2)=2.2^2-3.2-7
f (2)=8-6-7
f (2)= -5
2)
f (2)=2.2^2-3.2+7
f (2)=8-6+7
f (2)=9
It’s -5, always look at your rise and run, they will help!
