Write the equation of the graph obtained when the graph of y=1/x is compressed vertically by a factor of 0.25, translated 4 unit
NARA [144]

Answer:

y=\frac{0.25}{x-4}+3

Step-by-step explanation:

Notice that we are requested to perform three transformations in order: first a vertical compression (of the variable "y"), second a horizontal shift (affecting therefore the horizontal variable "x"), and lastly a vertical translation (affecting the variable "y")

1) Recall that a vertical compression by a factor 0.25 involves multiplying the full function y(x) by the factor 0.25:

y=0.25 * \frac{1}{x} \\y=\frac{0.25}{x}

2) the horizontal translation of 4 units to the right involves subtracting 4 from the variable "x":

y=\frac{0.25}{x-4}

3) the vertical translation 3 units up involves adding 3 to the full expression for "y":

y=\frac{0.25}{x-4}+3

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a​ single-strand electric
Luden [163]

Answer:

since the total amount of wire is not given, I looked for a similar question:

  • you have 800 yards of wire at your disposal

since we need to only calculate 3 sides of the land plot, our perimeter will be:

L + 2W = 800

area = L x W

L = 800 - 2W

now we replace:

area = (800 - 2W) x W = 800W - W²

we can write a quadratic equation:

area = -W² + 800W

the vertix of W = -b/2a

the coefficients of our quadratic equation are: -2 and 8

the vertix of W = -800 / (2 x -2) = -800 / -4 = 200 yards

width = 200 yards

length = 800 - (200 x 2) = 400 yards

maximum area enclosed = 200 x 400 = 80,000 sq yards

Beverly needs to make a container in the shape of a rectangular prism that holds 1000 in3 of liquid. The height of the container
anastassius [24]
Given:
volume = 1,000 in³
height = 10 in

1,000 in³ / 10 in = 100 in² Area.

100 in²

Length     Width        Surface Area of the Rectangular prism
100 in          1 in                       2,220 in²
  50 in          2 in                       1,240 in²
  25 in          4 in                          780 in²
  20 in          5 in                          700 in²
  

Surface area = 2(wl + hl + lw)

The best dimension is 20 inches by 5 inches by 10 inches. It has lesser surface area than other dimensions. Thus, it can save more materials.
