Answer:
9 days.
Step-by-step explanation:
We first subtract the amount already done from the total needed.
<em>10 - 1 = 9.</em>
Next, we take the remainder and divide it by the amount being made per day to get our final answer.
<em>9 / 1 = </em><em>9</em>.
The answer is 9 days.
Saying arccos(-√2/2) is the same as saying cos(x)=-√2/2. This is one the trigonometric values you should have memorized if you are taking a a trig class. In order to get √2/2, x must be equal to 45° or pi/4. But since it is a negative √2/2, the answer would be -45°or -pi/4.
There are technically multiple answers to this, but since you weren't given a range for the answers, I would stick with -45°.
Hope this helps
