One line passes through the points \blueD{(-3,-1)}(−3,−1)start color #11accd, (, minus, 3, comma, minus, 1, ), end color #11accd
mart [117]

Answer:

The lines are perpendicular

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are the same

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

Remember that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

<em>Find the slope of the first line</em>

we have the points

(-3,-1) and (1,-9)

substitute in the formula

m_1=\frac{-9+1}{1+3}

m_1=\frac{-8}{4}

m_1=-2

<em>Find the slope of the second line</em>

we have the points

(1,4) and (5,6)

substitute in the formula

m_2=\frac{6-4}{5-1}

m_2=\frac{2}{4}

Simplify

m_2=\frac{1}{2}

<em>Compare the slopes</em>

m_1=-2

m_2=\frac{1}{2}

Find out the product

m_1*m_2=(-2)(\frac{1}{2})=-1

therefore

The lines are perpendicular

Iteru [2.4K]

Answer:

C=0,10E+5

Step-by-step explanation:

La respuesta es que la expresión que indica el costo mensual "C" en función de la energía "E" consumida es:

C=0,10E+5

Esto teniendo en cuenta que se indica que hay una tarifa fija de $5 por mes y que a esto se debe sumar el resultado de multiplicar la energía consumida por el valor del kilowatt-hora.

The diagram shows the dimensions of a teepee. Find the volume of the building to the nearest cubic unit. Use 3.14 for pi.
LekaFEV [45]
The volume of a cone uses the following formula:

V =  \pi r^{2} \frac{h}{3}

Our diameter is 20 feet, so divide this by 2 to find the radius:

20 \div 2 = 10

We now have all of our values need to fill in the formula. Plug in these values:

\pi = 3.14, r = 10, h = 17

3.14 * 10^{2} *  \frac{17}{3}

3.14 * 100 * 5.67

314 * 5.67 = 1780.38

The volume of the cone is 1780 cubic feet.
