Mathematics

Given:

Equation of line is y=\dfrac{1}{4}x-7.

The perpendicular line passes through (-2,-6).

To find:

The point slope form of perpendicular line.

Solution:

We have,

y=\dfrac{1}{4}x-7

On comparing this equation with y=mx+b, we get

m=\dfrac{1}{4}

Slope of given line is \dfrac{1}{4}.

Product of slopes of two perpendicular of the lines is -1.

So, Slope\times \dfrac{1}{4}=-1

Slope=-4

Slope of required line is -4 and it passes through (-2,-6). So, the point slope form is

y-y_1=m(x-x_1)

where, m is slope.

y-(-6)=-4(x-(-2))

y+6=-4(x+2)

Therefore, the correct option is A.

Answer:

r = -189

Step-by-step explanation:

Let's make it easy,

-13=r/9+8

r/9 = -13-8

r/9 = -21

r = -21 × 9

r = -189

Pleaaaaaaaaaaaaaaaaaaase help meeeeee<br><br><br>i this correct
erma4kov [3.2K]

Answer:

15.3 miles.

Step-by-step explanation:

Area of trapezoid is given by = 1/2*( sum of parallel side) height

Given area of trapezoid = 221.85 sq. miles

Length of parallel sides = 19 miles and 10 miles.

Sum of parallel sides = 19 miles + 10 miles = 29 miles.

Plugging the above values in formula for area of trapezoid we have

Area of trapezoid is given by = 1/2*( sum of parallel sides) height

221.85 = 1/2 (29) height

=> 221.85* 2 = 29* height

=> 443.7 = 29* height

=> 443.7/29 =  height

=> height = 15.3

Thus, height is 15.3 miles.
