Answer:

A. because if you take 265,000 and multiply by 5,880,000,000,000 you will get 1,558,200,000,000,000,000 and put into scientific notation is 1.5582 X 10E18 (which means to the power of 18) which makes the answer A. also I know I'm late I was stumped myself and decided to actually apply myself and look at me now

Answer:

x intercept of CD = 17

Step-by-step explanation:

We are given a line AB with its end coordinates. and Another line segment CD which is perpendicular to AB. We have the coordinates of C , and we are asked to find the x intercept of line CD.

For that we need to find the equation of CD

we have coordinates of C , and hence if we have slope of CD we can find equation of CD

Slope of CD can be determine with the help of slope of AB as CD⊥ AB

So, the slope of CD $mCD = -\frac{1}{mAB}$
