Answer:

Statements 1, 3, and 5

1) Two rays joined at the same end point form an angle.

3) A continuous section of the circumference of a circle is a circular arc.

5) A circle is the locus of all points a fixed distance from a given center point.

Step-by-step explanation:

Statement 2 is false because it says that intersecting lines that form right angles are <u>parallel</u> lines.  Actually, intersecting lines that form right angles are perpendicular lines.

Statement 4 is false because it says that lines that never intersect of cross each other are <u>perpendicular</u>.  Actually, lines that never intersect or cross each other are parallel.

Solve the equation for the given variable 11=−4x+3
bekas [8.4K]

Answer: x=-2

Step-by-step explanation:

Given

11=-4x+3

Subtract 3 on both sides

11-3=-4x+3-3

8=-4x

Divide -4 on both sides

-4x/-4=8/-4

<h2>x=-2</h2>

What is the solution to the system of equations? 3x-6y=-12 " " x-2y=10 Use the substitution method to justify that the given sys
Thepotemich [5.8K]

The two lines in this system of equations are parallel

Step-by-step explanation:

Let us revise the relation between 2 lines

  • If the system of linear equations has one solution, then the two line are intersected
  • If the system of linear equations has no solution, then the two line are parallel
  • If the system of linear equations has many solutions, then the two line are coincide (over each other)

∵ The system of equation is

3x - 6y = -12 ⇒ (1)

x - 2y = 10 ⇒ (2)

To solve the system using the substitution method, find x in terms of y in equation (2)

∵ x - 2y = 10

- Add 2y to both sides

∴ x = 2y + 10 ⇒ (3)

Substitute x in equation (1) by equation (3)

∵ 3(2y + 10) - 6y = -12

- Simplify the left hand side

∴ 6y + 30 - 6y = -12

- Add like terms in the left hand side

∴ 30 = -12

∴ The left hand side ≠ the right hand side

∴ There is no solution for the system of equations

∴ The system of equations represents two parallel lines

The two lines in this system of equations are parallel

The original square has the area (8 in)^2 = 64 in^2.

If we mult. this area by 36, we get the area of a larger square 2304 in^2.

The new side length is sqrt(2304 in^2), or 48.  In other words, the original square has side length 8 in, but the 'new' square has side length 48 in.

The half-life of a certain radioactive material is 83 hours. An initial amount of the material has a mass of 67 kg. Write an exp
Anvisha [2.4K]

Answer:

  • Initial amount of the material is 67 kg
  • Hal-life is 83 hours

<u>The required equation is:</u>

  • m(x) = 67 * (1/2)^{x/83}, where m- remaining amount of the radioactive material, x - number of hours

<u>After 5 hours the material remains:</u>

  • m(5) = 67 * (1/2)^{5/83} = 64.260 (rounded)
