Answer:
r = 6 m
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
Substitute in what we know
37.68 = 2 * 3.14 * r
37.68 = 6.28 r
Divide each side by 6.28
37.68/6.28 = 6.28 r/6.28
6 = r
Answer: x = 0.421053y+5.263158
Step-by-step explanation:
x = 0.421053y+5.263158
The slope is 6 because x/y or rise/run and in x equal +1 which is positive 1 and y equal +6 which is positive 6... then you divide y by x which will be 6 divided 1 or 6/1 and that’s how it’s 6 :)
<u>Answer</u> : The demonstration is below :)
Step-by-step explanation :
<u>We use Pythagoras' </u><u>theorem </u><u>:</u>
- In the triangle ABC we have :
AB² = AC² - BC² = 15² - 9² = 144 = 12²
- In the triangle ABD we have :
DB² = AD² - AB² = 13² - 12² = 5²
cos(a) = BD/AD = 5/13
Answer:
-35
Step-by-step explanation:
when over the x-axis you change the y value to the opposite from neg. to positive or positive to negative
