Answer:
(a + b) = 8x +4
(a - b) = -2x +16
(a * b) = 
Step-by-step explanation:
We have been given the functions;
a(x) = 3x + 10 and b(x) = 5x − 6
Part A:
(a + b) = a(x) + b(x) # we simply add the two given functions
(a + b) = 3x + 10 + 5x − 6
(a + b) = 8x + 4
Part B:
(a - b) = a(x) - b(x) # we simply subtract the two given functions
(a - b) = (3x + 10 ) - (5x − 6)
(a - b) = 3x + 10 -5x +6
(a - b) = -2x + 16
Part C:
(a * b) = a(x)*b(x)
# we simply find the product of the two given functions
(a * b) = (3x + 10)*(5x − 6)
(a * b) = 
Surface area of a cone is (pi×r×l) + (pi×r^2)
So (3.14×7×17)+(3.14×7^2)=527.52yd^2
Answer:
We can use the <u>tan trig ratio</u> to calculate the steepness of each run.
The side <em>opposite</em> the angle is the <em>vertical </em>distance of each path.
The side <em>adjacent </em>to the angle is the <em>horizontal </em>distance of each path.
(see attached diagram)

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
