Answer:

The equation is 3x -5 + 10x -7 = 180°

Step-by-step explanation:

These angle are a linear pair. Linear pair are two angles that are adjacent and their sides are opposite rays, or the two angles form a straight angle = 180°

The equation is 3x -5 + 10x -7 = 180°

Answer:

What’s a reasonable domain for V(x)=x(11-2x)(17-2x)

Answers

Answer:

(-∞ , ∞)  -∞ < x < ∞

Step-by-step explanation:

function has no domain constraint

The domain of the expression is all real numbers except where the expression is undefined.

The given function is v(x)=x(11-2x)(17-2x).

What is domain and range of the function?

The B and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Interval Notation:(−∞,∞)

Set-Builder Notation:{x| x∈ R}

Therefore, the domain of the expression is all real numbers except where the expression is undefined.

Answers

Answer:

10 feet tall

Step-by-step explanation:

(Triangle problem was answered in a previous question)

So like before, we have a ratio: 1.5inches:2.5feet

We have a starting value as well: 6 inches

All we have to do is convert from inches to feet (not with a real life equation, but with the given equation)

To begin, dvide 6 by 1.5

6inches/1.5inches = 4 (The units canceled out during division)

Not multiply by the ratio:

4 * 2.5feet = 10 feet (It takes the units in feet)

Therefore, the tree is actually 10 feet tall.

What is the value of x which proves that the runways are parallel? What is the measure of the larger angle?

Answers

Answer:

118°

Step-by-step explanation:

When two parallel lines are cut by a tranversal, then the exterior angles are supplimentary and the corresponding angles are congruent.

Therefore the angle above (15x - 17)° is also (5x + 17)° and the angle below (5x + 17)° is also (15x - 17)°.

Angles on a straight line adds up to 180°. So to know the measure of the larger angle we must both equations and equal it to 180° to find x in order to know the larger angle.

(5x + 17) + (15x - 17) = 180

5x + 15x + 17 - 17 = 180

20x = 180

20x/20 = 180/20

x = 9°

Nkw let's substitute x = 9 into the equations

5x + 17 =

5(9) + 17 =

= 62°

15x - 17 =

15(9) - 17 =

= 118°

Both equations should add up to be 180°.

Therefore the measure of the largest angle is 118°.

Which of the following rational algebraic equation is transformable to a quadratic equation?​

Answers

Answer:

Option A

Step-by-step explanation:

Possible options are A and B as the other two have no variables in their denominators and the numerators are of degree 1.

Now, option A, it has two different denominators involving the variable s. If you multiply all the terms by the product of the two  8s(s + 2), then you get a quadratic equation.

The option B. If you perform same operation, multiply all the terms by m(m + 1) this will result in degree 3 polynomial, which is a cubic equation but not the quadratic.

So the only option is A

Just when did warp change from an imaginary.technology to an actual theory studied by real-life scientists? The answer is 1994, whenMiguel Alcubierre, a college physics student at the time, worked out the math.9 To understand Alcubierre's discovery, we need to talk a little more about AlbertEinstein After publishing his theory of special relativity in 1905, Einstein moved to a biggertheory: general relativity. Built on a set of "field equations"-formulas describing spaceand time that can have different solutions, depending how you use them-generalrelativity showed that space is like a fabric that's warped by gravity.10 Solving the Einstein field equations in his own way, Alcubierre found that a tiny.area of space in front of a ship could be compressed, while an area of space behindthe ship is expanded. This would generate a "warp bubble" that could move faster thanlight, carrying the ship inside like an ocean wave carries a surfer. Imagine that the wavecarrying the surfboard did not come from the wind, but instead were generated by anengine on the surfboard itself, and you'll understand the concept of warp drive11 Concepts are great, but can we learn to actually squeeze and stretch space like theSpandex of our workout pants?
