Write the equation of the line in slope intercept form equation of the line in slope intercept form is blank

Answers

Answer:

y=70x+20

Step-by-step explanation:

Okay so the slope is determined by having two points on the line in this case one of them is (0,20) and (2,160), you're going 140 up and 2 over so the slope would be [tex]\frac{140}{2}[/tex] which equals 70 so thats how you get m, to get b you simply put the y interecept which is at 20.

Plugs those numbers together you get y=70x+20 which is intercept form.

. If you walk around a circular path TWICE, and the circle has a diameter of 100 m, how far did you walk in TOTAL?

Answers

The total distance traveled was 638.3m.

How to calculate the distance traveled?

To calculate the perimeter of a circle we perform the following operations:

We must keep in mind that the radius of a circle is equal to half the diameter, so the radius of this circle is 100m divided by 2.

100m ÷ 2 = 50m

So the radius of this circle is 50m.

Subsequently, to find the perimeter of the circle we apply the following formula:

2 × π × radius of the circle = perimeter of the circle.

2 × 3.14 × 50 = 314.15m

According to this operation, the distance traveled in one lap would be 314.15m. So in two turns it would be:

314.15m × 2 = 638.3m

Answer:

1) A- 95

Step-by-step explanation:

1) 50 + 35+x = 180

85 +x = 180

x = 180- 85

2x - x + 7 = x + 3 + 4

Answers

Answer:0

Step-by-step explanation:

Simplifying

2x + -1x + 7 = x + 3 + 4

Reorder the terms:

7 + 2x + -1x = x + 3 + 4

Combine like terms: 2x + -1x = 1x

7 + 1x = x + 3 + 4

Reorder the terms:

7 + 1x = 3 + 4 + x

Combine like terms: 3 + 4 = 7

7 + 1x = 7 + x

Add '-7' to each side of the equation.

7 + -7 + 1x = 7 + -7 + x

Combine like terms: 7 + -7 = 0

0 + 1x = 7 + -7 + x

1x = 7 + -7 + x

Combine like terms: 7 + -7 = 0

1x = 0 + x

1x = x

Solving

1x = x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.

1x + -1x = x + -1x

Combine like terms: 1x + -1x = 0

0 = x + -1x

Combine like terms: x + -1x = 0

0 = 0

Simplifying

0 = 0

The solution to this equation could not be determined.

Rhombus

It can't be a pentagon because it only has four sides.

Properties of the shapes:

Rectangle - quadrilateral with two sets of congruent opposite sides and four right angles.

Rhombus - quadrilateral with four congruent sides.

Square - quadrilaterals with all properties of rectangles and rhombi.

Parallelogram - rectangles, rhombi, and squares are parallelograms.

This shape satisfies the properties of a square, meaning it is also a rectangle, rhombus, and parallelogram.

Distance between star from the sun is d = 4124966.128 AU

What is Trigonometry?

Trigonometry is the branch of mathematics that deals with particular angles functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle.

The astronomical unit distance between the star and the Sun can be calculated using the trigonometric function.

As per the given data:

distance from Earth to the Sun (P) = 1 AU

θ = 0.00001389 degrees

From tanθ:

tanθ = P/B

{P = perpendicular and B = base}

From the diagram:

tanθ = 1/d

tan(0.00001389) = 1/d

d = 1/tan(0.00001389)

d = 4124966.128 AU

The separation between the sun and the star is d = 4124966.128 AU.
