Antoine pulls a weight attached to a spring below its resting, or equilibrium, position. When Antoine releases the weight, it oscillates above and below its equilibrium position as shown in the table. The displacement of the weight from its equilibrium position, d(t), in centimeters, is modeled by a cosine function, where t represents time, in seconds. t 0 0.015625 0.03125 0.046875 0.0625 0.078125 0.09375
d(t) -20 -14.14 0 14.14 20 14.14 0

At which interval is the weight above its resting position? HINT: It's not C.

A. (0, 0.03125)
B. (0.03125, 0.09375)
C. (0.046875, 0.078125)
D. (0.03125, 0.0625)

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
