Answer:
Cost A = 125 + 50t
Cost B = 200 + 25t
Step-by-step explanation:
he makes 90 dollars and wasted 34 so he has 56 left
n=m+4
<h3>step-by-step explanation:</h3>
given formula,
n=3m-2l
and,
l=m+2
here in this question We have to substitute the values of "l" in the formulae
we get,
n=3m-2(m+2)
n=3m-2m+4
n=m+4
so if we complete the process correctly we get n=m+4
Answer:
Step-by-step explanation:
The point of closest approach is on a line perpendicular to the zip line
perpendicular lines have negative reciprocal slopes, so the perpendicular line has slope (8/3)
y = (8/3)x + b
adding our known point (3, 16)
16 = (8/3)3 + b
b = 8
y = (8/3)x + 8
now find where the two lines intersect by solving two equations with two unknowns
y = (-3/8)x + 8
as the two lines have a common y intercept of 8, that is the common point
(0, 8)
The distance from (0, 8) to (3, 16) is
d = √((3 - 0)² + (16 - 8)²) = √73 = 8.5440037453...
d = 8.5 ft
