Question

David tracks his calories burned while training for a meet. The number of calories he burns is expressed by the function c(t) = 704t, where t is the number of hours spent swimming.

To burn more calories, David wears flippers while he swims. The number of calories he burns while wearing flippers is expressed by the function b(c) = 1.3c, where c is the number of calories burned while swimming without flippers.

Which of the following composite functions expresses the calories, as a function of time, David burns while swimming with flippers?

Answer 1

b[c(t)] = 915.2t
b[c(t)] = 705.3t
c[b(t)] = 915.2t
c[b(t)] = 705.3t

Answer 2

what level of math is this?

Answer 14

If c(t)=704t, then what does c equals?

Answer 15

The calories burned

Answer 16

yes, but what is it equals in terms of value(number)

Answer 17

704

Answer 18

Yes that is correct.
And since b(c)=1.3c
b is 1.3 also

Answer 19

We would get 915.2t, right?

Answer 20

Using both of this,
b[c(t)] =?
c[b(t)] =?
Tell me what you get.

Answer 21

Yes 915.2t
Since it says calories as function of time, it means calories and time are related and depend on each other.
c(t)=704t, so the more time, the more calories burnt, therefore it is b[c(t)]=915.2t

Answer 22

Thank you!!

Answer 23

Yea, no problem!
