Preston have to get some correct and some incorrect answers.
0.6666 (repeating) x 0.75 = 0.5
0.6666 (repeating) / 0.75 = 0.8888888 (repeating)
Answer:
So, gradient is 2.
Step-by-step explanation:
Here Let's take points (3,4) and (4,6)
so
gradient(m) = (y2-y1)/(x2-x1)
= (6-4)/(4-3)
= 2/1
Remember that x =r cos theta and y = r sin theta. Thus,
x + y = r (cos theta + sin theta) = 4, or
r (cos theta + sin theta) = 4, or
4
r = -------------------------------
cos theta + sin theta
