Artist 52 [7]

Answer:

(x, y) -------- ( -x,-y)

Rule : Rotation center (0,0) , angle of rotation 180° or -180°

Step-by-step explanation:

The vertices of the object and image have coordinates at ;

D(-4,2), --------D'( 4,-2 ),

E (-1,3), --------E'( 1,-3 ),

F (-1,-3),--------F'(1,3),

G (-3,-4),------G'( 3,4 ),

You notice that after the rotation ;

( x, y )-------change to (-x,-y),

This rule is rotation center origin angle 180°

BRAINLIEST to wherever gets this correct

schepotkina [342]

Answer:

$300\pi$ cubic feet

Step-by-step explanation:

Let r be the radius of cone and h be the height of cone.

Radius of cylinder=r

Height of cylinder=h

Volume of cone= $100\pi ft^3$

We have to find the volume of cylinder.

We know that

Volume of cone= $\frac{1}{3}\pi r^2 h$

$100\pi=\frac{1}{3}\pi r^2 h$

$r^2 h=300$

Volume of cylinder= $\pi r^2 h$

Using the formula

Volume of cylinder= $\pi (300)=300\pi ft^3$

Hence, the volume of cylinder= $300\pi$ cubic feet

Solve nonhomogenous equation: x"+4x=cost

motikmotik

Answer:

$x(t) = Acos 2t + B sin 2t+\frac{cost}{3}$

Step-by-step explanation:

Given is a non homogeneous second degree equation as

$x"+4x=cost$

Auxialary equation is

$m^2+4 =0\\m = 2i, -2i$

Hence general solution is

x = Acos 2t + B sin 2t

Particular integral is = $\frac{cost}{D^2+4}$

Since t has coefficient 1, we substitute

$D^2 =-1\\PI = \frac{cost}{-1+4} =\frac{cost}{3}$

Hence full solution is

$x(t) = Acos 2t + B sin 2t+\frac{cost}{3}$
