Answer: c is perpendicular to y = -5x - 2

Explanation: The slope of a perpendicular line is an opposite reciprocal of the original slope/line. (Basically switch the numerator and denominator and the sign. In this case, the slope is -5/1x. It’s opposite reciprocal is 1/5x.)

You can take a look at my notes for further clarification. Hope this helps!

A grain distributor can process 14.6 tons of grain an hour.How much can the distributor process in 8.75 hours?
andrezito [222]
Hi there! For this question, all you have to do is multiply the two numbers. 14.6 tons are processed every hour. With this rate, we can find the amount processed in 8.75 hours. Multiply decimals like you do regular numbers. 14.6 * 8.75 is 127.75. There. The grain distributor can process 127.75 tons of grain in 8.75 hours.

In a right triangle, the length of the hypotenuse is 20 inches and the length of one leg is 15 inches. What is the length of the
VikaD [51]
Solutions 

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

<span>Given 

</span><span>In a right triangle, the length of the hypotenuse is 20 inches and the length of one leg is 15 inches. 

</span>c^2 = 20 in &#10;

&#10;a^2 = 15 in
<span>
</span>&#10;b^2 = Unknown 

------------ Calculations 
<span>
</span>b^2 = c^2 - a^2  

b^2 = c^2(20) - a^2(15) 

b^2 = 400 - 225 

b^2 = 175 

b =  \sqrt{175} 

b = 13.2287565553 &#10;
