<u>Step-by-step explanation:</u>
Input x = 13, y = 84, r = 85 into the trig functions:
Answer:
X=5
Step-by-step explanation:
X^2=4^2+3^2
X^2=25
X=5
Answer:
6:7
Step-by-step explanation:
divide both sides by 7...
19 - 2 = 17 17 - 4 = 13 number = 13
AB is divided into 8 equal parts and point C is 1 part FROM A TO B, so the ratio is 1:7, with C being 1/7 of the way. The ratio is k, found by writing the numerator of the ratio (1) over the sum of the numerator and denominator (1+7). So our k value is 1/8. Now we need to find the rise and the run (slope) of the points A and B.
. That gives us a rise of -4 and a run of 12. The coordinates of C are found in this formula:
. Filling in accordingly, we have
which simplifies a bit to
. Finding common denominators and doing the math gives us that the coordinates of point C are
. There you go!
