Answer:
The sine and cosine are equal for 45 degrees.
Choose the triangle that has a 45-deg angle.
The question is incomplete. The complete question is :
A sine function that has an amplitude of 16 units, a period of 5 units,a vertical displacement of 3 units up and a phase shift of 2.5 units left. Graph this function and show each step.
Solution :
The standard form of the sine function is
y = a sin (bx - c) + d
Here given :
Amplitude, a = 16
Period :
⇒ 
Phase shift : 

∴ 
The vertical displacement : d = 3 units up
Now substituting a, b, c and d values in the standard form gives :


The graph is attached below.

Step-by-step explanation:
Answer:
a. If a polygon is a rectangle, then it is a square
False
b. If a polygon has four 90 degree angles, then it is a rectangle
True
c. If the formula for a shape's area is base time height, it is a rectangle
False
Known :
Rectangular 1 :
l1 = 12 in
w1 = 6 in
h1 = 12 in
Rectangular 2 :
l2 = 18 in
w2 = 8 in
h2 = 10 in
Asked :
Volume = ...?
Answer :
V = V rectangular 1 + V rectangular 2
= (l1 × w1 × h1) + (l2 × w2 × h2)
= (12 × 6 × 12) + (18 × 8 × 10)
= 864 + 1.440
= <u>2</u><u>.</u><u>0</u><u>3</u><u>4</u><u> </u><u>in</u><u>³</u>
So, the volume of the figure is 2.034 cubic inches.
