Hi There!
----------------------------------
Question 2:
Obviously the right equation for this question is Point Slope Form.
Point Slope Form: y - y1 = m(x - x1)
y1 = -1
x1 = 3
m = 2
Question 2 Answer: y + 1 = 2(x - 3)
Question 3:
Again use point slope form.
Find Slope:
7 - 1 = 6
-2 - 1 = -3
6/-3 = -2
Question 3 Answer: y - 1 = -2(x - 1)
Hope This Helps :)
We have been given a function . We are asked to find the formula which gives the x-coordinates of the maximum values for given function.
We know that cosine function oscillates between and 1 that is minimum value of cosine is and maximum value is .
We also know that and after period of cosine is . This means after every , we will get to .
So maximum of cosine is , where n is an integer.
Therefore, our required formula is , where,
Answer:
Circumference=2πr or πd
So:
3.14 × 6cm
=18.84cm
1/1 I think I hope this helps
