Find the equation of a line that passes through the point (4,2) that is perpendicular to the line y=4/3 x

Mathematics

Mrac [35]3 years ago

Answer:

y=\frac{3}{4}x-1

Step-by-step explanation:

Since we're looking at perpendicular lines, the slope of the new line is the reciprocal of the original line.

So the slope of our new line is \frac{3}{4}

So far, we are looking at y=\frac{3}{4} x+b

Now we need to find the b value by plugging in the given point.

2=\frac{3}{4}(4)+b\\  2=3+b\\ b=-1

So the final equation is y=\frac{3}{4}x-1

Which of the following statements about the number line is true?
nadya68 [22]
d. Numbers get smaller as you move to the left on the number line.

And conversely when the number moves along to the right it increases by interval of typically 1. Why does this happen? Because this phenomenon is the illustration of how number are ordered and hierarchical. Integers can better explain the numbers beyond 0. The existence of the negative numbers which is obviously less in value than the real numbers 1 , 2 , 3 and so on.

A cone has a volume 12 pie cubic inches it’s height 4 inches what is the radius?
insens350 [35]

Answer:

<h2>r = 3 in</h2>

Step-by-step explanation:

The formula of a volume of a cone:

V=\dfrac{1}{3}\pi r^2H

r - radius

H - height

We have V = 12π in³ and H = 4 in. Substitute:

12\pi=\dfrac{1}{3}\pi(r^2)(4)\qquad\text{multiply both sides by 3}\\\\36\pi=4\pi r^2\qquad\text{divide both sides by}\ 4\pi\\\\9=r^2\to r=\sqrt9\to r=3
