Answer:
The function given is:
P(x) = 15x² + 350x - 2000
or
y = 15x² + 350x - 2000
Interchange x and y:
x = 15y² + 350y - 2000
x = (y√15)² + 2(y√15)(45.19) + (45.19)² - (45.19)² - 2000
x = ( y√15 + 45.19)² - 4042.14
( y√15 + 45.19)² = x + 4042.14
Take square root:
y√15 + 45.19 = (√(x + 4042.14))
y√15 = (√(x + 4042.14)) - 45.19
The minimum value of x, for which function is defined and real, is x= -4042.14
Hence, the range of inverse is x ≥ -4042.14
Answer:
x= -13
Step-by-step explanation:
x + 6 = -7
Subtract 6 from both sides of the eqaution
x+6 - 6= -7 -6
Simplify
x+6 - 6= -7 -6
x= -7 -6
Subtract the numbers
x= -13
Answer:
Area = 24 in.²
Step-by-step explanation:
Area of the parallelogram = base × height
base = 6 in.
height = h = ?
Use pythagorean theorem to find h
Thus:
h² = 5² + 3²
h² = 25 - 9
h² = 16
h = √16
h = 4 in.
Plug the values into the formula for area of parallelogram
Area = 6 × 4
Area = 24 in.²
Fast shuttle : 5 + 0.25m
steady shuttle : 2 + 0.50m
when will they be equal.....so set them equal and solve for m, the number of miles
5 + 0.25m = 2 + 0.50m
5 - 2 = 0.50m - 0.25m
3 = 0.25m
3 / 0.25 = m
12 = m <=== so they will cost the same at 12 miles
