Find the coordinates of P(a,b) whose ordinate is twice as much as abscissa and sum of coordinates is -12.

ser-zykov [4K]

Answer:

P(- 4, - 8 )

Step-by-step explanation:

The abscissa is the x- coordinate and the ordinate is the y- coordinate.

Here b = 2a , thus

a + 2a = - 12

3a = - 12 ( divide both sides by 3 )

a = - 4

and b = 2a = 2 × - 4 = - 8

P(- 4, - 8 )

Use cylindrical coordinates. Find the volume of the solid that lies within both the cylinder x2 y2

Sedaia [141]

Answer:

hello your question is incomplete here is the complete question

Use cylindrical coordinates Find the volume of the solid that lies within both the cylinder x^2 + y^2=16 and the sphere x^2 + y^2 + Z^2= 81

Answer : $\frac{4 \pi }{3} [729 - 65\sqrt{65} ]$

Step-by-step explanation:

The given data

cylinder = x^2 + y^2 = 16

sphere = x^2 + y^2 +z^2 = 81

from the given data the solid is symmetric around the xy plane hence we will calculate half the solid volume above the plane then multiply the sesult by 2

Note : we are restricting our attention to the cylinder x^2 + y^2 = 16 and also finding the volume inside the sphere which gives bound on the z-coordinate as well

the r parameter goes from 0 to 4

jeyben [28]

Answer:

The answer is "0.9258201 or $\bold{ \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}}$ ".

Step-by-step explanation:

$\to P= 30 \ \%\\\\ \to x= 18 \\\\ \to n=50\\\\\\\hat p= \frac{x}{n} = \frac{18}{50} = 0.36 \\\\\bold{Formula:}\\\\X= \frac{\hat p -p}{\sqrt{\frac{p \times (1-p)}{n}}}\\\\$

$= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times (1-0.3)}{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.21}{50}}}\\\\= \frac{0.06}{\sqrt{0.0042}}\\\\= \frac{0.06}{0.064807407}\\\\= 0.9258201$
