The given formula is a sinusoidal equation. 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 cos(Bx + C) + D

where

A = amplitude
B = frequency
C = shift on starting angle
D = shift of wave on the y-axis

Thus, can pattern out that A=1, B=5, C=0 and D=0 in the given equation. The SI unit of frequency is Hertz (Hz) or 1/second. Hence, the frequency of the function is 5 Hz.

The radius of the circle is increasing at a rate of 2 meters per minute and the sides of the square are increasing at a rate of

Lunna [17]

Answer:

Change in area=24 $\pi$ -48

Step-by-step explanation:

Let s will be the side of square and r will be the radius of circle.

Then two given conditions are

1)dr/dt=2 m/s

2)ds/dt=1 m/s

Area enclosed=(Area of square)-(Area of circle)

Area of square= $s^{2}$

Area of circle= $\pi r^{2}$

Area enclosed= $(\pi r^{2})-s^{2}$

dA/dt=2 $\pi$ r(dr/dt)-2s(ds/dt)

At s=24,and r=6

dA/dt=2( $\pi$ )(6)(2)-2(24)(1)

Change in area=24 $\pi$ -48

A complete table with values for x or y that make this equation true:3x+y=15

Andreyy89

Answer:

Step-by-step explanation:

The given equation is: $3x+y=15$ ,

Now, putting x=2 in above equation,

$3(2)+y=15$

$y=15-6=9$

Now, put y=3 in the given equation,

$3x+3=15$

$3x=12$

$x=4$

Putting x=6,

$3(6)+y=15$

$y=15-18$ $y=-3$

Putting x=0,

$0+y=15$

$y=15$

Putting x=3,

$3(3)+y=15$

$y=15-9$

$y=6$

Putting y=0,

$3x+0=15$

$x=5$

Putting y=8,

$3x+8=15$

$3x=7$

$x=\frac{7}{3}$
