Answer:
Using SohCahToa we know it will be opposite over adjacent, opposite being the side across from theta and adjacent being the side next to theta, Using Toa we know it will be opposite over adjacent so the answer will be 6/2sqrt5
If they wants you to simplify more than you cant have a sqrt on the bottom so to fix this you will multiply the top and bottom by sqrt5 leaving you with 6sqrt5/ 2*5 or 6sqrt5/15
hope this helped
Yes, f(x) = 16 - 7x is a linear function because there are no exponents and the rate of change (which is the slope) only adds or subtracts a certain number each time.

If x is meant to equal the square footage of the house then we can substitute 1900 for x.
y = 0.074(1900) + 50.48
y = 140.6 + 50.48
y = 191.08
If y is meant to equal square footage then substitute 1900 for y.
y = 0.074x + 50.48
1900 = 0.074x + 50.48
1900 - 50.48 = 0.074x
1849.52 = 0.074x
1849.52/0.074 = x
24,993. 51 = x
1.68 / 3 = 0.56 per can
2.45 / 5 = 0.49 per can
the 5 cans for 2.45 is better because it is cheaper per can.
