Answer:

y = -1/2x +1/2

Step-by-step explanation:

Point B is 4 up and 2 over from point A. So, the midpoint will be 4/2 = 2 up and 2/2 = 1 over, at (1, 0).

The ratio of rise to run between A and B is ...

m = rise/run = 4/2 = 2

The perpendicular line will have a slope that is the opposite reciprocal of this, -1/2.

Then the point-slope equation for the perpendicular bisector is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y -0 = -1/2(x -1) . . . .line with slope -1/2 through point (1, 0)

y = -1/2x +1/2 . . . . simplified to slope-intercept form

Store display volume of each cube shaped box is 125 cubic inches of the display has six layers of boxes how high is the display

Doss [256]

Answer:

30 inches

Step-by-step explanation:

We know that the formula for calculate the volume of a cube is:

∨=8³

Where "s" is the length of each side.

Since the volume of each cube-shaped box is 125 cubic inches, we can find "s":

125 in³=8³

∛125 in³=8

8=5 in

We know that the display has six layers of boxes, then , to calculate the height of the display, we can multiply the value of "s" obtained before by 6.

Then:

height= (5 in)(6)=30 in

Answer:

1. y= 25400(1 + 0.11)^x

2. 2019

Step-by-step explanation:

1. y = a(1 + r)^x

(exponential growth formula :

a = initial value (the amount before measuring growth or decay)

r = growth or decay rate (usually represented as a percentage and expressed as a decimal)

x = number of time units that have passed)

y= 25400(1 + 0.11)^x

so in 1 year, in 1996, we would say

y=25400(1+0.11)^1

y=25400(1.11)

y=28194

2. I found the answer by plugging in numbers into x

with x = 24

y= 25400(1+0.11)^24

y= 310874

so in 24 years, the population will surpass 302438 which would be 1995+24= 2019
