CAN SOMEONE PLEASE HELP ME? 13. Problem of the Matthew chapter determines that the braking distance, in meters, from a moving car at about 100 km / h corresponds roughly at d = -2.8 t - 5)^2+ 70, where t is the time elapsed, in seconds.

a) Determine the reciprocal of this function. What does it represent in the context of the question?

b) In this context, what should be the domain and image of function and its reciprocal?

c) Compare the distance traveled during each of the first three intervals 20 s from the start of braking.

i thinks A

Step-by-step explanation:

the answers is A I had this

c

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
