Answer:

y = -3x + 14

Step-by-step explanation:

y=x/3−1

The slope of the perpendicular line is the reciprocal of the given equation.

Given is 1/3x. Perpendicular slope is m=-3x

Substitute the perpendicular slope and the point (4,2) in an equation

y = mx + b

2 = -3(4) + b

2 = -12 + b

Find b by isolating

b = 2+12

b = 14

Substitute the slope -3x and b=14 to find the equation of the line.

y = mx + b

y = -3x + 14

<h3>Answer: Choice D.  12,600 feet</h3>

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

Explanation:

We have two similar triangles here, so we can set up the proportion below to solve for x

5200/(5200+6500) = 5600/x

5200/11700 = 5600/x

5200x = 11700*5600 .... cross multiply

5200x = 65,520,000

x = (65,520,000)/(5200)

x = 12,600 which shows why the answer is choice D

side note: 12,600 ft = 2.386 miles approximately

Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)
Naddika [18.5K]

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

suppose the circumference of a crop circle is 150.7968 hectometers (hm) what's the radius of the circle? (usett=3.1416)​
gulaghasi [49]

Answer:

The radius of the circle is 24\ hm

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=2\pi r

In this problem we have

C=150.7968\ hm

\pi=3.1416

substitute and solve for r

150.7968=2(3.1416)r

r=150.7968/(2(3.1416))=24\ hm
