Sinusoidal equations are trigonometric functions involving sine and cosine functions. Graphically, they look like wave patterns having amplitudes and periods. The general form of a sinusoidal equation is
y = A sin(Bx + C) + D
where
A = amplitude
B = frequency
C = shift on starting angle
D = shift of wave on the y-axis
From the given problem, A = 1 and D = 3. There is no value for C because there is no mention of any shift in angle. About the frequency, you can obtain this by getting the reciprocal of the period. Thus, B = 2/π. The complete equation is
y = sin(2x/π) + 3
Each of them should pay $7.77 because I added the total from the movie and the snack and got $23.31. Since there is three friends, I divided $23.31 by 3 and got $7.77.
Part 1) <span>What is the maximum volume of a square pyramid that can fit inside a cube with a side length of 18 cm?
we know that
[volume of a square pyramid]=(1/3)*b</span>²*h
where
b is the length side of the square base-----> 18 cm (is equal to the length side of cube)
h is the height---------> 18 cm (is equal to the length side of cube)
[volume of a square pyramid]=(1/3)*18²*18----> 1944 cm³
the answer Part 1) is
c. 1,944 cm³
Part 2) <span>Find the volume of the cylinder in terms of Pie. The diagrams are not drawn to scale.
</span>
volume of a cylinder=pi*r²*h
for r=2.2 m
h=12 m
volume of a cylinder=pi*2.2²*12-----> volume=58.08*pi m³
the answer Part 2) is
58.08*pi m³
I think the answer is, r= C/2<span>π</span>
Answer:
18+30 = 48
6(3+10) = 78
so they're not equal
Step-by-step explanation:
to be equal we have to change 6(3+10) to 6(3+5)
18+30 = 48
6(3+5) = 48
now they're equal
