Answer:
The equation that matches the function shown is option;
C. 
Step-by-step explanation:
The given graph of the function is a sinusoidal graph
The values of 'x' and 'y' coordinates at the maximum, x-intercept and minimum points are given as follows;
x,
y
0
0
π
1
2·π
0
3·π
-1
4·π
0
We note that sin(π/2) = 1, sin(π) = 0 sin(3·π/2) = -1, and sin(4·π/2) = sin(2·π) = 0
Therefore;
y = the sine of half the x-value
Which is presented as follows;
.

Answer:
The answer is A and D.
Step-by-step explanation:
Acute angles are angles that are less than 90°.
0° < θ < 90°.
So by looking at the diagram, any angles that are smaller than a L-shaped(90°) are all acute angle.
m<1=23
m<2=90
m<3=67
m<4=113
m<5=67
the square means it is 90° so 2 is 90°.
all of the angles combined equals 360 so.
360-67-90= 203
since there is a straight line splitting down the middle. m<4=180-67=113
so m<4=113
now you would go 360-67-113-90=90 so
m<1 + m<3 =90
180-90-67=23.
m<1=23
360-67-23-90-113=67
m<3=67
