For the function given, state the middle line: ƒ(t) = 3 cos(π t − 1).

1 answer:

5 0

The amplitude is 3 since y = A cos (B ) + C
The vertical shift is C = 0 and B = π t - 1 ( horizontal frequency and shift )
This means that the graph oscillate between -3 and 3.
The middle line is y = 0.

Find the volume of the cylinder in terms of pi.

Allushta [10]

Answer:

$\large\boxed{V=81\pi\ in^3}$

Step-by-step explanation:

The formula of a volume of a cylinder:

$V=\pi r^2H$

r - radius

H - height

We have r = 3in and H = 9in. Substitue:

$V=\pi(3^2)(9)=\pi(9)(9)=81\pi\ in^3$

The area of tapazuim is 400 cm 2 the distance between the parallel sides is 16 cm.if one of the parralel sides is 20 cm,find the

german

the other parallel side is 30 cm

Step-by-step explanation:

here's the solution :-

let the other parallel side be x

now,

=》Area of trapezium =

$\frac{1}{2} \times sum \: of \: parallel \: sides \times height =》[tex] \frac{1}{2} \times (x + 20) \times 16 = 400$

=》( x + 20 ) × 8 = 400

=》x + 20 = 400 ÷ 8

=》x = 50 - 20

=》x = 30

so length of other parallel side = x = 30 cm
