We are given
A computer downloads a 5-minute video at a constant rate
and we know that
slope is rate of change of date per unit time
and it is changing at a constant rate
so, that constant rate will be slope
and we know that that rate is speed of downloading
so, slope is speed of downloading...........Answer
One side of the cube has area 3.2^2 = 10.24 m^2
There are 6 sides so the answer is 6 * 10.24 = 61.44 m^2
The x-coordinate of our midpoint = 3
The x-coordinate of Y = 0
k = x-coordinate of Z
3 = (0 + k) / 2
Multiply both sides by 2
6 = k + 0
Simplify
6 = k
The y-coordinate of our midpoint = 3
the y-coordinate of Y = 5
w = y-coordinate of Z
3 = (w + 5) / 2
Multiply both sides by 2
6 = w + 5
Subtract 5 from both sides
1 = w
For problem #17, Z(6, 1)
Let's do problem 18 now.
The x-coordinate of our midpoint = 5
The x-coordinate of Y = -1
k = x-coordinate of Z
5 = (k + (-1)) / 2
Multiply both sides by 2
10 = k + (-1)
Simplify the right side
10 = k - 1
Add 1 to both sides
11 = k
The y-coordinate of our midpoint = 9
The y-coordinate of Y = -3
w = y-coordinate of Z
9 = (w + (-3)) / 2
Multiply both sides by 2
18 = w + (-3)
Simplify the right side
18 = w - 3
Add 3 to both sides
21 = w
For problem #18, Z(11, 21)
So you add and subtract and multiple
35% of $70 =
= 35% * $70
= 0.35 * $70
= 24.5
The markup is $24.50.
