Question 1 of 10 Freya is training for a track race. She starts by sprinting 200 yards. She
gradually increases her distance, adding 5 yards a day for 21 days.
Which explicit formula models this situation?
O A. an = 21 + (n - 195
O B. an=200+ (n-1)5
O C. an-5+ (n - 1,200
D. an-200 + (n - 1921

4400

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

answer is 8 r5

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
