Identify the sequence graphed below and the average rate of change from n = 1 to n = 3. coordinate plane showing the point 2, 10
Katena32 [7]

Answer:

  • geometric sequence with initial value 20 and common ratio 1/2
  • average rate of change on [1, 3] = -7.5

Step-by-step explanation:

(a) The given points have sequential values of x and values of y that are each 1/2 the value before. The common ratio tells us the sequence is a geometric sequence.

(b) The first given point is (2, 10), so extrapolating backward, we determine the previous point to be ...

... (2-1, 10/(1/2)) = (1, 20)

Thus, we have enough information to determine the average slope between n=1 and n=3.

... (difference in y)/(difference in n) = (5 -20)/(3 -1) = -15/2 = -7.5

BRAINLIESTT ASAP! PLEASE HELP ME :)<br><br> Solve for x in the figure below. Show your work.
nikdorinn [45]

Answer:

x = 19°

Step-by-step explanation:

we can see from observation that 22° and (3x+11)° are complementary. I.e they add up to 90°

hence

22 + (3x+11) = 90

22 + 3x+11 = 90

33 + 3x = 90   (divide both sides by 3)

11 + x = 30  (subtract 11 from both sides)

x = 30 - 11

x = 19°

andrew-mc [135]
Since there are greater costs to farming organically, organic produce is more expensive for consumers. The total cost to produce an organic crop relates directly to the price consumers pay for it.
