How to solve for z 6-1/2z=2/3

sergey [27]

6 - 1/2z = 2/3
Steps
First, subtract 6 from both sides
6 - 1/2z - 6 = 2/3 - 6
Then, simplify
-1/2z = -16/3
Then, multiply both sides by -2
(-1/2z) (-2) = (-16/3) (-2)
Then, simplify
z = 32/3

Which of these points is the closest to the point (7, 1) ?

pantera1 [17]

Step-by-step explanation:

Solution

The general equation of the plane passing through (2,5,−3) is

a(x−2)+b(y−5)+c(z+3)=0 .........(1)

Now, this plane passes through B(−2,−3,5) and C(5,3,−3).Then we have

a(−2−2)+b(−3−5)+c(5+3)=0

⇒−4a−8b+8c=0

⇒−a−2b+2c=0 ..........(2)

a(5−2)+b(3−5)+c(−3+3)=0

⇒3a−2b=0 ..........(3)

Solving (2) and (3) we get

0+4

6−0

2+6

⇒

=λ(say)

⇒a=4λ,b=6λ,c=8λ

Substituting the values of a,b and c in (1), we get

4λ(x−2)+6λ(y−5)+8λ(z+3)=0

⇒4(x−2)+6(y−5)+8(z+3)=0

⇒4x+6y+8z−14=0

⇒2x+3y+4z−7=0

This is the equation of the plane determined by the points A(2,5,−3),B(−2,−3,5) and C(5,3,−3)

Now, the distance of this plane from the point (7,2,4) is

∣(2×7+3×2+4×4)−7∣

4+9+16

∣(14+6+16)−7∣

4+9+16

∣36−7∣

units.

Thus, the distance between the point (7,2,4) and the plane 2x+3y+4z−7=0 is

units.

The height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 24π cubic units. What is the hei

Ira Lisetskai [31]

Answer:

<h2>6 units</h2>

Step-by-step explanation:

Let, Radius = r units

Height ( h ) = 3r units

Volume ( V ) = 24π units³

Now,

Let's find the height of the cylinder:

$\pi {r}^{2} h \: = 24\pi$

${r}^{2} (3r) = 24$

Calculate the product

$3 {r}^{3} = 24$

Divide both sides of equation by 3

$\frac{3 {r}^{ 3} }{3} = \frac{24}{3}$

Calculate

${r}^{3} = 8$

Write the number in the exponential form with an exponent of 3

${r}^{3} = {2}^{3}$

Take the root of both sides of the equation

$r = 2$

Replacing value,

Height = 3r

$= 3 \times 2$

Calculate

$= 6 \: units$

Hope this helps..

Best regards!!
