Notice that the two semicircles have a radius of 10/2=5 and that their area is simply the area of a complete circle with a radius of 5. In the center you have a rectangle that is 10 by 8. So the total area is:
A=pr^2+xy
A=25p+80 m^2
A≈158.53 which is:
A≈158.5 m^2 (to the nearest tenth of a m^2)
The function f(x)=4sin(2πx) is a sinusoidal function
The graph of the function f(x)=4sin(2πx) is graph (c)
<h3>How to determine the graph of the function f(x)=4sin(2πx)?</h3>
The parent function of a sine function is
f(x) = sin(x)
The function f(x)=4sin(2πx) implies that the parent function f(x) = sin(x) has been horizontally and vertically stretched
So, the graph of the function f(x)=4sin(2πx) would have a higher amplitude and shorter period than its parent function
Hence, the graph of the function f(x)=4sin(2πx) is graph (c)

Answer:
B. 4.0 liters
Step-by-step explanation:
1 can = 0.4 l
10 cans = 0.4l x 10
0.4l x 10 = 4l
10 cans = 4l
“10 more that” means “add 10 to something”
“twice” means “multiply something by 2”
Use “x” or another variable for “a number”
Twice a number: 2*x or 2x
10 more than twice a number: add 10 to 2x
Answer: 2x+10
