Answer:
1.) Domain: [-2, 1] Range: [1, 2] 2.) Domain: [-1, 2] Range: [-2, 2]
Step-by-step explanation:
The bus stop method is just like division.
Ex
137÷5=
1.) 5 goes into one zero times so there is a zero on top.
2.) 5 goes into 13 two times, so after the zero there is a 2.
3.) 5 goes into 37 seven times so there is a 7 after the 2.
4.) There is a 2 left and five can't go into school therefore that is a remainder.

Answer:
<u>Andre’s neighbor pays him $ 10 each week to mow the lawn </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Cost of Andre's dad gift = $ 40
Weekly donation to the food bank = $ 2
Number of weeks to save $ 40 = 5
2. How much does Andre’s neighbor pay him each week to mow the lawn?
Let's calculate this amount, this way:
Weekly payment = [Cost of the gift + (Weekly donation * Number of weeks to save)]/Number of weeks
Replacing with the real values we know:
Weekly payment = [40 + (2 * 5)]/5
Weekly payment = 50/5 = 10
<u>Andre’s neighbor pays him $ 10 each week to mow the lawn </u>
cos(2<em>θ</em>) + sin²(<em>θ</em>) = 0
Half-angle identity:
cos(2<em>θ</em>) + (1 - cos(2<em>θ</em>))/2 = 0
Simplify:
2 cos(2<em>θ</em>) + 1 - cos(2<em>θ</em>) = 0
cos(2<em>θ</em>) = -1
Solve for <em>θ</em> :
2<em>θ</em> = arccos(-1) + 2<em>nπ</em>
2<em>θ</em> = <em>π</em> + 2<em>nπ</em>
<em>θ</em> = <em>π</em>/2 + <em>nπ</em>
where <em>n</em> is any integer.
