Answer:
(b) Ingrid’s claim is correct, but her steps are incorrect
Step-by-step explanation:
As nearly as we can tell from the problem statement, Ingrid's table looks like the one attache. We have highlighted the incorrect steps.
Step 3 should read ...
0·cos(y) -(-1)·sin(y) = sin(y) . . . . . . . . . sin(-π/2) = -1
Step 4 should read ...
0 + sin(y) = sin(y)
So, Ingrid's conclusion is correct, but her steps are incorrect.
The distance that Kirsten and Molly need to bike on their third day is obtained by subtracting the sum of the distances they have traveled after two days from the length of the entire route.
distance left = 156 miles - (64 miles + 45 miles)
= 47 miles
Thus, Kirsten and Molly need to bike 47 miles on their third day.
Entire distance is
25/2(1+1/4+(1/4*1/2))
=25/2(1+1/4+1/8)
=25/2(8/8+2/8+1/8)
=25/2(11/8)
=275/16
=17 3/16 miles [assuming you need fractions as answers]
2.2367 , therefore to the nearest hundredth it would be 2.237
