12. Find the distance between points P(-1, 2) and Q(-3, 4).

marusya05 [52]

Answer:

D=2.82

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

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

Where

$(x_1,y_1) = (-1,2)$

$(x_2,y_2) = (-3,4)$

Replacing these values in the distance formula

$D =\sqrt{(-1-(-3))^2+(2-4)^2}$

$D =\sqrt{(-1+3)^2+(-2)^2}$

$D =\sqrt{(2)^2+4}$

$D =\sqrt{4+4}$

$D =\sqrt{8}$

$D= 2.8284$

Hence the Distance is 2.82 units

Write the equation of a line that is parallel to y=6x and that passes through the point (-7,1)

Anna35 [415]

Answer:

so y=6x+43

Step-by-step explanation:

Slope is 6, so using y=mx+b

1=6(-7)+b, b = 43

so y=6x+43

Ivan is painting 3 walls in his living room. Each wall measures 9 3/4 feet tall by 14 1/4 feet wide. Ivan needs to estimate the

Alenkinab [10]

Answer:

The estimated area is $416\frac{13}{16}\ ft^{2}$

Step-by-step explanation:

we know that

To estimate the area that Ivan will paint , calculate the area of one wall and then multiply by 3

step 1

Convert the dimensions to an improper fractions

$9\frac{3}{4}\ ft=\frac{9*4+3}{4}=\frac{39}{4}\ ft$

$14\frac{1}{4}\ ft=\frac{14*4+1}{4}=\frac{57}{4}\ ft$

step 2

Find the area of one wall

$(\frac{39}{4})*(\frac{57}{4})=\frac{2,223}{16}\ ft^{2}$

step 3

Multiply the area of one wall by 3

$(3)*\frac{2,223}{16}=\frac{6,669}{16}\ ft^{2}$

step 4

Convert to mixed number

$\frac{6,669}{16}=\frac{6,656}{16}+\frac{13}{16}=416\frac{13}{16}\ ft^{2}$
