You are asking for the condition needed for the 
<span>two segments to be perpendicular to each other. </span>

<span>If the slope of one segment is m, then the slope of a perpendicular segment would be -1/m </span>

<span>this means that m2 = -1/m and so m2 x m = -1 </span>

<span>If you look carefully at your choices, the 3rd answer involves the two slope and has the -1. It's </span>
<span>the correct answer.</span>

The condition that seems to fit the bill in regards to, two line segments to be actually perpendicular to one another is "C" or the third choice (x3, y3). Now the obvious question is to how one gets to this conclusion? Now if one considers one segment to be equal to "m", then the perpendicular segment to it would be "-1/m". This also means
m^2 = -1/m
m^2 * m = -1
This actually proves that "C" is the correct answer.

Damon buys lumber worth $562. He gets a 20% contractor's discount. The sales tax is 6%. His credit gives him 2% off. How much do
Virty [35]

Answer: 629.44

Step-by-step explanation:

562 times .2 = 112.4 that’s the 20% discount. 562-112.4 = 449.6 times 1.4 = 629.44

You have an account that starts at $2500 with an interest rate of 3.25% compound yearly. How much is in the account after 10 yea
SSSSS [86.1K]

Answer:3,312.50

Step-by-step explanation:1. We assume, that the number 2500 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 2500 is 100%, so we can write it down as 2500=100%.

4. We know, that x is 3.25% of the output value, so we can write it down as x=3.25%.

5. Now we have two simple equations:

1) 2500=100%

2) x=3.25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

2500/x=100%/3.25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
