Step-by-step explanation:
Answer:
<u>First blank:</u> 2. Extrapolation
<u>Second blank:</u> 2. 69
Step-by-step explanation:
Extrapolation should be used because the point (x, y) is further than the points included in the table, that is, the x-coordinate will be greater than 12 when y = $0
Replacing y = 0 into the equation, we get:
0 = -115.9x + 8,007.30
115.9x = 8,007.30
x = 8,007.30/115.9
x = 69
sin 8 x = 2 sin 4x cos 4x =
= 2 * 2 sin 2x cos 2x cos 4 x =
= 4 * 2 sin x cos x cos 2x cos 4x =
= 8 sin x cos x cos 2x cos 4x ( correct )
Look at the dots for each week and see how much money was in the account.
Week 1 was 10, week 2 was 30, this means he saved 20
Week 5 was at 50, week 6 was at 80, this means he saved 30, which was the most.
The answer is 5 & 6.
