Answer:

y = 0.5cos(4(x+π/2)) -2

Step-by-step explanation:

The centerline of the oscillation is at -2, so only the 2nd and 4th choices are viable.

The multiplier of x is computed from (2π)/period. One period is π/2, so the multiplier of x is ...

... 2π/(π/2) = 4 . . . . . matching the 2nd selection.

The horizontal offset in the second equation (π/2) is of no consequence, as it is one full period of the function.

The peak-to-peak amplitude of the oscillation is 1 unit, so the multiplier of the cosine function (which usually has a peak-to-peak value of 2 units) is 0.5. Every offered answer has that characteristic.

The appropriate choice is the 2nd one:

... y = 0.5cos(4(x+π/2)) -2

Answer:

24.5

Step-by-step explanation:

Year 2000 would be 1, so year 2016 would be 17

Your equation is 1.5x - 1, and since we have x = 17, we simply plug it in:

1.5(17) - 1

25.5 - 1

24.5 is our estimated population using the line of best fit.

Your city is having a sneaker convention! A pair of Ground Morgans is 20% less expensive than a pair of Elite Butterflies, Elite

Amanda [17]

Answer:

Ground Morgans are 52% the price of Floating Jumps.

Step-by-step explanation:

A pair of Ground Morgans $GM$ is 20% less expensive than a pair of Elite Butterflies $EB$ , this means

$GM= 0.8 EB$ (GM is 80% the price of EB's)

Elite Butterflies $EB$ are 30% more expensive than Cloud Trainers $CT$ 's, this means

$EB =1.3 CT$ (EM's is 130% the price of CT's)

Cloud Trainers $CT$ are 50% less expensive than Floating Jumps $FJ$ , this means

$CT=0.5FJ$ (CT is 50% the price of FJ)

Now, if we want the price of Ground Morgans in terms of Floating Jumps, then, since EB = 1.3 CT,

$GM=0.8 (1.3CT)$

and since CT = 0.5F, we have

$GM = 0.8(1.3(0.5FJ))$ .

Simplifying we get

$\boxed{GM =0.52FJ}$

Ground Morgans are 52% the price of Floating Jumps.
