Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.
i.e.
<span>B. Original is a function; inverse is a function </span>
SinB = cosC = AC / BC = 8/10 = 4/5;
tgB = ctg C = AC/AB = 8/6 = 4/3, because we use T. Pitagora for calculating AB;
sinC = cosB = AB/ BC = 6/10 = 3/5;
tgC = ctgB = AB/ AC = 6/8 = 3/4.
You have to multiply 8 and 2 1/2 which is 20. Then divide 20 and 200. Then you get 10 and that is your answer.
Do you know what the answer choices are?
Answer:
The line is 
.
Step-by-step explanation:
Given:
Point and slope (0,0) and 2/3.
Now, to determine the line.
Here the point is:
And the slope is:
Now, putting the formula and substituting the value from above to determine the line:
Therefore, the line is .
