Answer:

the y intercept is -2

Step-by-step explanation:

the y intercept is always the value on the end

Answer slope-intercept form is y = mx+ b y = m x + b, where m m is the slope and b b is the y-intercept. y = mx +b y = m x + b Find the values of m m and b b using the form y = mx+b y = m x + b.

Answer:

x = 8.7

Step-by-step explanation:

The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:

8 = 12

We can simplify this down to

2 = 3

Now that we have this proportion we can apply it to Lines AE and EC

2(13) = 3x

26 = 3x

8.67 = x

Therefore x is equal to 8.67 (or 8.7 rounded)

Check:

8/12 = 0.6667

8.6667/13 = 0.6667

Since both are the same, the answer is correct.

I hope this helps!!

Given:

Consider the given statement is

[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]

To prove:

The given statement.

Solution:

We have,

[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]

Taking LHS, we get

[tex]LHS=\sqrt{\sec^2\theta+\text{cosec}^2\theta}[/tex]

[tex]LHS=\sqrt{\dfrac{1}{\cos^2\theta}+\dfrac{1}{\sin^2\theta}}[/tex]

[tex]LHS=\sqrt{\dfrac{\sin^2\theta+\cos^2\theta}{\sin^2\theta\cos^2\theta}}[/tex]

[tex]LHS=\sqrt{\dfrac{1}{\sin^2\theta\cos^2\theta}}[/tex]            [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]

[tex]LHS=\dfrac{1}{\sin\theta\cos\theta}[/tex]

[tex]LHS=\dfrac{\sin^2\theta+\cos^2\theta}{\sin\theta\cos\theta}[/tex]            [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]

[tex]LHS=\dfrac{\sin^2\theta}{\sin\theta\cos\theta}+\dfrac{\cos^2\theta}{\sin\theta\cos\theta}[/tex]

[tex]LHS=\dfrac{\sin\theta}{\cos\theta}+\dfrac{\cos\theta}{\sin\theta}[/tex]

[tex]LHS=\tan \theta+\cot \theta[/tex]

[tex]LHS=RHS[/tex]

Hence proved.

Answer: 12.1 ft

Step-by-step explanation:

A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.

c² = a² + b²

Where:

c = hypotenuse

a = base

b = Height

c² = 11² + 5²

c² = 121 + 25

c² = 146

c = √146

c = 12.1 ft

35 miles I'm not sure I think my phone is glitching out on the question because It is in a weird format

The approximate distance from the ranger's current position to the tree is 0.652 miles.

To solve this problem, we can use trigonometry and create a diagram based on the given information.

Let's assume the ranger's starting position (marked A) is the origin (0,0) on a coordinate plane, and she walks along the river to position B. We need to find the distance between the ranger's current position and the tree.

Based on the information provided:

The tree is sighted about 60 degrees north of east from position A.

The tree is sighted at 40 degrees north of west from position B.

Now, let's calculate the coordinates of position B. Since each unit on the map is 1 mile, we can assign coordinates (x, y) to position B.

At position B, we can break down the distance into the horizontal and vertical components:

The horizontal distance from A to B is the same as the horizontal distance from B to the tree.

The vertical distance from A to B is the same as the vertical distance from B to the tree.

Let's denote the horizontal distance as d h and the vertical distance as d v.

From position A, we have:

Horizontal component: d h = d * cos(60°)

Vertical component: d v = d * sin(60°)

From position B, we have:

Horizontal component: d h = d * cos(40°)

Vertical component: d v = d * sin(40°)

Since both d h and d v are the same at position B, we can set up the following equation:

d * cos(40°) = d * cos(60°)

Simplifying the equation, we have:

cos(40°) = cos(60°)

To solve for d, we can divide both sides by cos(40°):

d = cos(60°) / cos(40°)

Using a calculator or trigonometric table, we can find the values of cos(60°) and cos(40°):

cos(60°) ≈ 0.5

cos(40°) ≈ 0.766

Substituting these values:

d ≈ 0.5 / 0.766

Calculating the result:

d ≈ 0.652

Therefore, the approximate distance from the ranger's current position to the tree is 0.652 miles.

The solution to the system of equation y = 2x - 4 and y = 3/2x - 2 is (4, 4).

Graphical solutions of a system of equations are way of finding the intersection points of all the equations given.

A system with two or more than two equations has a solution only when they have a common intersection point.

Given are two equations of a line they are,

4x - 2y = 8⇒ - 2y = - 4x + 8 ⇒ y = 2x - 4 and y = 3/2x - 2.

The intersection of these two lines are (4, 4) and hence it is the solution

Answer: the third one

Step-by-step explanation:

Answer:

no solution

Step-by-step explanation:

Given

- 2(v - 2) = - 3 - 2v ← distribute left side

- 2v + 4 = - 3 - 2v ( subtract 4 from both sides )

- 2v = - 7 - 2v ( add 2v to both sides )

0 = - 7 ← not possible

This indicates the equation has no solution
