Answer:

The answer is \sqrt{20}.

Step-by-step explanation:

Use the Pythagorean Theorem.  

2^{2} + 4^{2} = c^{2} \\4+16 = c^{2} \\\sqrt{20} = c

<h3>Answer: sqrt(20)</h3>

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

Explanation:

Count out the spaces, or use subtraction, to find the horizontal side BC is 2 units long. Similarly, you'll find the vertical side AC is 4 units long.

Use the pythagorean theorem to find the length of segment AB.

a^2 + b^2 = c^2

2^2 + 4^2 = c^2

4 + 16 = c^2

20 = c^2

c^2 = 20

c = sqrt(20)

We stop here since it matches with choice B.

-----------------

Optionally, we can simplify like so

sqrt(20) = sqrt(4*5)

sqrt(20) = sqrt(4)*sqrt(5)

sqrt(20) = 2*sqrt(5)

What is the equation of a line perpendicular to the line y=(4/9)x-2 that passes through the point (4,3)?
Hoochie [10]
<span>y=(4/9)x-2
This is in slope intercept form (y=mx+b), where m is the slope. 
A perpendicular line will have the opposite reciprocal of the slope.
So if the slope here is 4/9, then the perpendicular line's slope will be -9/4.

Now that you have the slope (-9/4) and a point (4, 3), you can use the point-slope formula to find the equation.
y - y</span>₁ = m(x - x₁)
y - 3 = (-9/4)(x - 4)
y - 3 = (-9/4)x + 9
y = (-9/4)x + 12

So the answer will be:
C. <span>y= -(9/4)x+12</span>

A pencil costs $0.60 plus sales
lord [1]

Answer: 5%

Step-by-step explanation:

To find the sales tax, find the difference between before and after tax:

0.63 - 0.60 = 0.03

To find the percentage, divide the difference by the cost of the product:

0.03/0.60 = 0.05

Multiply by 100 to find percent sales tax:

0.05 x 100 = 5%
