Find the equation of a plane that is perpendicular to the vector −4i⃗ −4j⃗ −k⃗ and passing through the point (−2,−5,5)

vredina [299]

hello ....

the equation of a plane that is ; ax+by+cz +d =0

the vector perpendicular to this plane is : V(a,b,c)

in this exercice ; a = -4 b= -4 c = -1

then: the equation of a plane that is ; -4x-4y-z +d =0

but the plane passing through the point (−2,−5,5) :

-4(-2)-4(-5)-(5) +d =0

23+d =0

d =-23

the equation of a plane is : -4x-4y-z-23 =0

The complex polygon below represents the layout of a parking lot. Find the area of the parking lot in square meters.

alukav5142 [94]

Answer:

The area of the parking lot is: 144cm^2

Step-by-step explanation:

Given

See attachment for polygon

Required

The area of the parking lot

The attached plot has 6 congruent triangles with the following dimension;

$Base = 6cm$

$Height = 8cm$

$Area = \frac{1}{2} * Base * Height$

$Area = \frac{1}{2} * 6cm * 8cm$

$Area = 24cm^2$

The area of the 6 triangles is:

Area = 6 * Area of 1 triangle

$Area = 6 * 24cm^2$

$Area = 144cm^2$

A particle is moving with the given data. Find the position of the particle. v(t) = 1.5√t , s(4) = 14.

Leto [7]

Answer:

$s(t) = t^{\frac{3}{2} } +6$

Step-by-step explanation:

given that a particle is moving with velocity given by the function v(t)

We have to find the position of the particle

$v(t) = 1.5\sqrt{t}$

Since v is the derivative of s, we can find s by integrating v wrt t

$s(t) = \int v(t) dt \\=\int 1.5\sqrt{t} dt\\=1.5 *\frac{2}{3} t^{\frac{3}{2} } +C$

where C is the arbitrary constant of integration.

Use the fact s(4) = 14

$s(t) = 1.5 *\frac{2}{3}* t^{\frac{3}{2} } +C\\s(4) = 1.5 *\frac{2}{3}*4^{\frac{3}{2} } +C=14\\8+C=14\\C = 6$

So position of particle at time t is given by

$s(t) = t^{\frac{3}{2} } +6$
