Which of the following steps is included in the construction of a perpendicular line through a point on a line?

Molodets [167]

Answer:

Connect arcs that are above the original line with a straightedge ⇒ 2nd

Step-by-step explanation:

* Lets revise how to construct a perpendicular line through a point

on the line

- Given: line AB and point P lies on it

1. Place your compass pin at P and draw an arc of any size below

AB that crosses the line twice at points C and D

2. Stretch the compass to a larger distance

3. Place the compass pin on point C and draw a small arc above

the line

4. Without changing the distance of the compass place the

compass pin on point D and draw another small arc intersects

the small arc from C at point E

5. Using a straightedge, to join P which is on the original line and E

which is the intersection point of the two small arcs above the

original line, then PE is perpendicular to AB at E

- From the steps up the step is including in the construction of a

perpendicular line through a point on a line is:

Connect arcs that are above the original line with a straightedge

* Remember:

- The step of Connect arcs that are above and below the given line

with a straightedge is in the construction a perpendicular from a

point off the line

- The step of Create arcs on either side of a point that is off the

given line is in the construction of a perpendicular bisector

of a line

- The step of Create a copied angle by using the first two lines as the

original angle in the construction of the parallel lines

Let W be part of the solid sphere of radius 4, centered at the origin, that lies above the plane z = 2. Set up an integral in cy

andriy [413]

Answer:

V = ∫∫∫rdrdθdz integrating from z = 2 to z = 4, r = 0 to √(16 - z²) and θ = 0 to 2π

Step-by-step explanation:

Since we have the radius of the sphere R = 4, we have R² = r² + z² where r = radius of cylinder in z-plane and z = height² of cylinder.

So, r = √(R² - z²)

r = √(4² - z²)

r = √(16 - z²)

Since the region is above the plane z = 2, we integrate z from z = 2 to z = R = 4

Our volume integral in cylindrical coordinates is thus

V = ∫∫∫rdrdθdz integrating from z = 2 to z = 4, r = 0 to √(16 - z²) and θ = 0 to 2π

Which equation shows a valid step in solving /2x-6+2x+6=0?

AfilCa [17]

An equation which shows a valid step that can be used to solve the given mathematical equation is $(\sqrt[3]{2x - 6})^3 = (-\sqrt[3]{2x + 6})^3$

<h3>What is an equation?</h3>

An equation simply refers to a mathematical expression that can be used to show the relationship existing between two (2) or more numerical quantities.

In this exercise, you're required to show a valid step which can be used to solve the given mathematical equation. Since both equations are having a cube root, the first step is to take the cube of both sides.

Take the cube of both sides, we have:

$\sqrt[3]{2x - 6} + \sqrt[3]{2x + 6} = 0\\\\(\sqrt[3]{2x - 6})^3 + (\sqrt[3]{2x + 6})^3 = 0^3\\\\(\sqrt[3]{2x - 6})^3 = (-\sqrt[3]{2x + 6})^3$
