algol13

Answer:

x=2 and y= -1

Step-by-step explanation:

substitute x value in equation 2

2(5y+7)+4y=0

10y+14+4y=0

14y = -14

y= -1

here,

x= 5(-1)+7

x= -5+7

x=2

\bf 5sin(2x)=3cos(x)\qquad \qquad  sin(2\theta)=2sin(\theta)cos(\theta)\qquad thus&#10;\\\\&#10;5[2sin(x)cos(x)]=3cos(x)\implies 10sin(x)cos(x)=3cos(x)&#10;\\\\&#10;10sin(x)cos(x)-3cos(x)=0\impliedby \textit{taking common factor}&#10;\\\\\\&#10;cos(x)[10sin(x)-3]=0\implies &#10;\begin{cases}&#10;cos(x)=0\to &\measuredangle x=cos^{-1}(0)&#10;\\\\&#10;sin(x)=\frac{3}{10}\to &\measuredangle x = sin^{-1}\left( \frac{3}{10} \right)&#10;\end{cases}

A cone with a radius of 6 cm and a height of 8 cm has the same volume as a cylinder with a height of 6 cm. What is the radius
babunello [35]

Answer:

The radius of the cylinder is 4 cm.

Step-by-step explanation:

Given:

radius of cone = 6 cm

height of the cone = 8 cm

height of cylinder = 6 cm

We need to find the radius of cylinder.

Solution:

First we will find the volume of cone.

Volume of cone is one third time square of radius times height times π.

framing in equation form we get;

Volume of cone = \frac{1}{3}\pi r^2h = \frac{1}{3}\pi\times 6^2\times 8 \approx 301.44 \ cm^3

Now Volume of cylinder is given by square of radius times height times π.

framing in equation form we get;

Volume of cylinder = \pi r^2h=18.84r^2

Now it has been given that;

Volume of cone is equal to Volume of cylinder.

so we can say that

18.84r^2=301.44

Dividing both side by 18.84 we get;

\frac{18.84r^2}{18.84}=\frac{301.84}{18.84}\\\\r^2\approx16

Taking square root on both side we get;

\sqrt{r^2}=\sqrt{16}  \\\\r=4\ cm

Hence the radius of the cylinder is 4 cm.
