we are given that
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.
The explicit formula that models this situation is
we have been asked to find how far does she sprint on day 21?
Substitute the value of n=21 in the given explicit formula we get
Simplify we get
Hence the correct option is A.
205 yards is my answer now
306 square meters.
Divide the shape into 2 rectangles.
Lets do the one that is sticking to the top first.
The area is 6 * 15, which is 90.
Lets do the second rectangle. The area is:
27 * 8, which is 216.
Add them all up (90 + 216), which is 306.
