What is the midpoint of the segment shown below ?

umka21 [38]

Hey there! :)

Answer:

(5, 1/2)

Step-by-step explanation:

Recall that the midpoint formula is:

$(x_m, y_m) = (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Plug in the point values to solve for the midpoint:

$(\frac{5+5}{2}, \frac{-3+4}{2} )$

Simplify:

$(\frac{10}{2}, \frac{1}{2})$

(5, 1/2) is the midpoint.

A rectangular piece of cardboard that is 7 inches by 20 inches has squares of length x inches on a side cut from each corner.

adoni [48]

Answer:

The remaining area in the form of a polynomial function $A(x)= 140-4x^2$ where 0 < x < 3.

Step-by-step explanation:

Breadth of rectangular piece of cardboard = 7 inches

Length of rectangular piece of cardboard = 20 inches

Area of cardboard = $Length \times Breadth$

Area of cardboard = $20 \times 7$

Area of cardboard = $140 in^2$

Squares of length x inches on a side cut from each corner.

Length of square = x

Area of 1 square = $Side^2 = x^2$

Area of 4 squares = $4x^2$

Area of remaining portion $A(x)= 140-4x^2$

So, the remaining area in the form of a polynomial function $A(x)= 140-4x^2$ where 0 < x < 3.
