ANSWER
3) b
EXPLANATION
Given that:

and

Recall that the sine and cosine functions are equal for complementary angles.
This implies that,


Each day his study time is increasing. Find a common denominator, in this case 8
1/4 = 2/8
5/8 = 5/8
1 = 8/8
So he went from
2/8 to 5/8 to 8/8 which is an increase of 3/8 each day. If this pattern continues Thursday would be 11/8 and Friday 14/8.
14/8 = 1 6/8 = 1 3/4 hours
(an hour and 45 minutes)
Answer:
9 m³
Step-by-step explanation:
The formula for calculating the volume (V) of a cuboid is
V = depth × width × height
= 1.8 × 2.5 × 2 = 9 m³
