Explanation: $21 / $7=3 boxes
The gievn equation is ,

where t is the time in seconds and h is the no.of hamburgers assembled.
put h = 2 in equation (1).

blank A assembles 2 hamburges in 22.6 seconds.
put h = 3 in equation (1)

blank B assembles 3 hamburgers in 33.9 seconds.
put h = 5 in equation (1)

blank C assembles 5 hamburgers in 56.5 seconds.
put h = 8 in equation (1)

blank D assembles 8 hamburgers in 90.4 seconds.
It shouldn't be too tough to find one of those, seeing that there are
an infinite number of them.
To create one, take any integer, positive or negative, and multiply it by itself.
Here are a few to put you in the mood:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, ...
784, 841, 900, 1024, 1225, 1600, 2500, 3600, 4900, 10000, 1 million, ...

t(99)= -2.89
Step-by-step explanation:
-To places after the decimal point is equivalent to rounding off to the nearest hundredth.
-To round off to the nearest hundredth, we check the thousandths digit:
- If the thousandths digit is less than5, we round down to the previous hundredth.
- If the thousandths digit is greater than 4, we round up to the next hundredth:
Hence,
