Step-by-step explanation:
Given f(x) then f(x - 2) represents a horizontal translation of f(x) shifted 2 units to the right, thus
The marked points on f(x) → f(x - 2) are
(0, 0 ) → (2, 0 )
(2, 4 ) → (4, 4 )
(3, 9 ) → (5, 9 )
Let the distance of the first part of the race be x, and that of the second part, 15 - x, then
x/8 + (15 - x)/20 = 1.125
5x + 2(15 - x) = 40 x 1.125
5x + 30 - 2x = 45
3x = 45 - 30 = 15
x = 15/3 = 5
Therefore, the distance of the first part of the race is 5 miles and the time is 5/8 = 0.625 hours or 37.5 minutes
The distance of the second part of the race is 15 - 5 = 10 miles and the time is 1.125 - 0.625 = 0.5 hours or 30 minutes.
A = 1/2bh...for h
multiply both sides by 2
2A = bh
now divide both sides by b
(2a)/b = h
