Answer:

if there is no equation given with the problem, then all you do is read the y coordinate value corresponding to 25 mins and 40 mins.

here f(25) looks yo be 7 and f(40) looks yo be 20.

Make a conjecture about the rules these patterns follow.

Step-by-step explanation:

1) 3, 6, 9, 12, 15

6 - 3 = 9 - 6 = 12 - 9 = 15 - 2
Each term is 3 more than the previous term.

2) 9, 3, 1, 1/3, 1/9

3/9 = 1/3 = (1/3)/1 = (1/9)/(1/3) = 1/3
Each term is 3 times less then the previous term.

3) a, c, e, g, i, k, m

a = 1, c = 3, e = 5, g = 7, i = 9, k = 11, m = 13
Each letter is 2 places right from the previous letter of English alphabet

4) 0, 5, -2, 3, -4, 1, -6

5 - 0 = 5, -2 - 5 = -7
3 - (-2) = 5, -4 - 3 = -7
1 - (-4) = 5, -6 - 1 = - 7
Each odd numbered term is 7 less than the previous term, each even numbered term is 5 more than the previous term

5) 4, 8, 16, 32, 64, 128

8/4 = 16/8 = 32/16 = 64/32 = 128/64 = 2
Each term is twice the previous term

6) 0.1, 0.01, 0.001, 0.0001

0.1/0.01 = 0.01/0.1 = 0.001/0.01 = 0.0001/0.001 = 0.1
Each term is 10 times less than the previous term

Find the length of AC. (Need help asap)

Ivan

AB is a diameter so radius of circle is 24/2 = 12

Now AC = 2π *12 * (150/360) ≈ 31.42

PLEASE HELP ME WITH THIS!!

<h3>Answer: Choice D. (6,12)</h3>

Explanation:

The translation $(x,y) \to (x+1,y-1)$ tells us to add 1 to the x coordinate and subtract 1 from the y coordinate.

For point R(1,5) we'll arrive at R'(2,4) after applying that translation or shifting mentioned. We have moved the point 1 unit to the right and 1 unit down.

Now apply the dilation with a scale factor of 3, centered at the origin. Basically it means we triple each coordinate. We'll go from R'(2,4) to R''(6,12)
