Answer:
f(2) = 1
Step-by-step explanation:
f(x) where x = 2
we plug this into the function named f(x) and solve with the value plugged in
f(2) 1/2(2) = 1
6(m + 2 + 7m)
A. 6m + 12 + 42m AND 48m + 12
B. 6(m + 2 + 7m) is equivalent to 6m + 12 + 42m because it's just simplified I just distributed.
6(m + 2 + 7m) (Given)
6m + 12 + 42m (distribute)
C. 6(m + 2 + 7m) is equivalent to 48m + 12 because it's just simplified I just distributed and then combined like terms:
6(m + 2 + 7m) (Given)
6m + 12 + 42m (distribute)
48m + 12 (combine like terms)
If the required rate is gallons per minute, then its obvious from the question, that the rate of filling the pool is 10 gallons per minute, and its obviously a constant number.
But for the rate to be in gallons per hour, then
1 minute corresponds to 10 gallons
so
1 hour corresponds to 10x60 = 600 gallons
hence
rate (gallons per hour) = 120,000/600 = 200 gallons per hour.
which is again a constant number.
Answer: x = 21

Answer:
Step-by-step explanation:
This is a right angled triangles and the summation of the other two angles must equal 90°
OR you can also say that the summation of all the angles in a ∆ must give us 180°
Therefore (2x+14) + (4x-26) = 90°
Expanding... By collecting all like terms, we have
2x+4x+14-26-90 = 0
6x - 102° = 0
Therefore, 6x = 102
x = 102/6
x = 17°
