I've read all of them carefully.
A calculator won't help you do 1-4.
It might be a little bit useful for 5 and 6, but only slightly. If you know your math then you shouldn't have any trouble with those either.
Answer:
x = 25
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is
x - 8 = × 34 = 17 ( add 8 to both sides )
x = 25
Answer:
(y-3) = 2(x-1)
Step-by-step explanation:
Point slope form is
(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line
(y-3) = 2(x-1)
Answer:
18.66 ft/s
Step-by-step explanation:
The distance between you and the elevator is given by:
The rate of change for the distance between you and the elevator is given by:
Applying the chain rule:
Therefore, at x=300 and y = 500, dy/dt is:
The elevator is descending at 18.66 ft/s.
