Answer:
See graph
Step-by-step explanation:
We want to graph
on the interval 
We need to plot some few points












This will give us one cycle.
We then use the pattern to complete the graph on the interval

Answer:
There are 120 1st graders at Sierra Elementary School this year
Step-by-step explanation:
Let n represent the total number of 1st graders at Sierra Elementary School
Since 45% of all 1st graders at Sierra Elementary School are female students and this year there are 54 female 1st graders, 45% of n is equal to 54
→ n(
) = 54
→ 45n = 5400
→ n = 120
Answer:
D. 161°
Step-by-step explanation:
m<2 is congruent to m<4, m<1 is congruent to m<3 by properties of a parallelogram
to find x:
4x-17=3x-8
x-17=-8
x=9
m<4=3(9)-8=19
so, m<4=19°
m<2 =19°
to find m<1:
the interior angles of a parallelogram add up to 360°
360-2(19)=2x
2x=360-38
2x=322
x=161°
m<1=161°
Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.
Let's change 0.02 into a percentage.
This means that every year, her investment will earn a <em>2% simple interest.</em>
