What is the distance between (1, -4) and (1, 18​
Annette [7]
<h3>Answer: 22 units</h3>

=====================================================

Explanation:

You can use the distance formula

d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{ (1-1)^2 + (-4-18)^2}\\\\d = \sqrt{ (0)^2 + (-22)^2}\\\\d = \sqrt{ 22^2}\\\\d = 22\\\\

----------------

A shorter method is to subtract the y coordinates and apply absolute value

So either |-4-18| = |-22| = 22

Or, |18 - (-4)| = |18+4| = |22| = 22

This method only works because the x coordinates are the same. We can also use this method if the y coordinates were the same with the x coordinates being different.

Find the Area of the figure below, composed of an isoceles trapezoid and one
MAVERICK [17]

Answer:

the total area is 15.6 square units

Step-by-step explanation:

hello,

you can  find the total area  dividing the shape into two known shapes

total area= area of the trapezoid +area of the semicircle

then          

step one

find the area of the isosceles trapezoid using

A=\frac{a+b}{2}*h

where

a is the smaller base

b is the bigger base

h is theheight

A is the area

let

a=2

b=5

h=4

put the values into the equation

A=\frac{a+b}{2}*h\\A=\frac{5+2}{2}*4\\A=3.5*4\\A=14

Step two

find the area of the semicircle

the area of a circle is given by

A_{c}=\pi  \frac{d^{2}}{4}\\

but, we need the area of  half circle, we need divide this by 2

A_{semic}=\frac{ \pi \frac{d^{2}}{4}}{2}\\A_{semic}= \pi \frac{d^{2}}{8}

now the diameter of the semicircle is 2, put this value into the equation

A_{semic}= \pi \frac{2^{2}}{8}\\\\A_{semic}= \pi \frac{1}{2}\\ A_{semic}=\frac{\pi }{2}\\

find the total area

total area= area of the trapezoid +area of the semicircle

total\ area= 14+\frac{\pi }{2} \\total\ area=15.6

so, the total area is 15.6 square units

Have a good day.
