The given triangle is a right triangle

<h3>The length and slope</h3>

The coordinates are given as:

D (0,n), E(m,n), F(m,0)

The length is calculated using:

$l=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2$

So, we have:

$DE=\sqrt{(0-m)^2 + (n-n)^2} = m$

$DF=\sqrt{(0-m)^2 + (n-0)^2} = \sqrt{m^2 + n^2$

$EF=\sqrt{(m-m)^2 + (n-0)^2} = n$

The slope is calculated using:

$m = \frac{y_2 -y_1}{x_2 - x_1}$

So, we have:

$DE = \frac{n -n}{0- m} = 0$

$DF = \frac{n -0}{0- m} = -\frac nm$

$EF = \frac{n -0}{m- m} = \mathbf{unde fined}$

<h3>The coordinates of the midpoints</h3>

This is calculated using

$m = 0.5 * (x_1 + x_2, y_1 + y_2)$

So, we have:

$DE = 0.5 * (0 + m, n+ n)=(0.5m, n)$

$DF = 0.5 * (0 + m, n+ 0)=(0.5m, 0.5n)$

$EF = 0.5 * (m + m, n+ 0)=(m, 0.5n)$

<h3>The type of triangle</h3>

In (a), we have:

<u>Lengths</u>

$DE= m$

$DF = \sqrt{m^2 + n^2$

$EF= n$

<u>Slope</u>

$DE = 0$

$DF = -\frac nm$

$EF = \mathbf{unde fined}$

The sides are not equal.

However, the 0 and the undefined slope implies that the triangle is a right triangle because the sides are perpendicular

It should be noted that the triangle cannot be graphed because the coordinates are not numeric

A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.M.

Tasya [4]

Answer:

<h2>2.55gallons.min</h2>

Step-by-step explanation:

given that the initial time before pumping is 3:40 p.M.

after pumping the time reads 3:44, hence he use 4 min to fill his tank

time taken=4 min

also given is that had pumped 10.2 gallons

the capacity of tank= 10.2gallon

Then the average rate of pump is

average rate= capacity of tank/time taken

average rate= 10.2/4min

average rate=2.55gallons.min

This is a radical equation

riadik2000 [5.3K]

To solve for p, square both sides and move the equation to one side is equal to zero. Then factor. I chose -2 and -5 because -2 x -5 = 10 and -2 + -5 = -7. After factoring, solve p-5=0 and p-2=0. When one of those equals zero then the equation (p-5)(p-2)=0 is true.

90+31= 121
3x-1+121=120
3x+120=180
-120
3x=60
Divide by 3 on both sides
X=20
