Question

select the correct answer from each drop - down menu. let ( d(t) ) be the total number of miles joanna has cycled, and let ( t ) represent the number of hours before stopping for a break during her ride. ( d(t)=12t + 20 ) so, ( d(4)=square ). this means that after (square), joanna (square).

Explanation:

Step1: Substitute t = 4 into d(t)

We have the function \( d(t) = 12t + 20 \). To find \( d(4) \), we substitute \( t = 4 \) into the function.
\( d(4)=12\times4 + 20 \)

Step2: Calculate the value

First, calculate \( 12\times4 = 48 \). Then, add 20 to it: \( 48+20 = 68 \).
This means that after 4 hours, Joanna has cycled 68 miles.

Answer:

For \( d(4) \), the value is 68. The first drop - down (after "d(4) =") should be 68. The second drop - down (after "after") should be "4 hours". The third drop - down (after "Joanna") should be "has cycled 68 miles".
