What is the common difference of the following arithmetic sequence?
100, 102, 104, 106,…
Answers
The common difference in the arithmetic sequence 100, 102, 104, 106,... is 2.
Arithmetic Sequence: 100, 102, 104, 106,...
Common Difference: The common difference in an arithmetic sequence is the constant value by which each term is increased or decreased. In this sequence, the common difference is 2 because each term increases by 2.
Calculation: 102 - 100 = 2, 104 - 102 = 2, 106 - 104 = 2, so the common difference is 2.

A ramp leading to the freeway overpass is 200 feet long and rises 37 feet. what is the measure of the angle formed between the ramp and the freeway?
Answers
First, we find the angle made between the ramp and the rise (dashed line). Let's denote this is angle α. We make use trigonometric functions like cosine. Cosine of an angle is equal to the ratio of its adjacent side to the hypotenuse. In equation form:
cos α = 37/200, where α is the angle of inclination of the ramp
cos α = 0.185
α =cos^-1(0.185)
α = 79.34°
Next, let's denote the unknown angle as angle β. When you add the right angle and angle α, the sum would be angle β. Therefore,
β = 90° + 79.34°
β = 169.34°
A ramp leading to the freeway overpass is 200 feet long and rises 37 feet. The measure of the angle formed between the ramp and the freeway is
[tex]\mathbf{ \theta = sin^{-1} \Big ( \dfrac{37}{200} \Big)}[/tex]
From the information given:
The measure of the angle formed θ between the ramp and the freeway overpass can be determined by using the sine angle which is:
[tex]\mathbf{sin \theta = \dfrac{opposite}{hypotenuse}}[/tex]
[tex]\mathbf{sin \theta = \dfrac{37}{200}}[/tex]
[tex]\mathbf{ \theta = \dfrac{1}{sin} \Big( \dfrac{37}{200}\Big)}[/tex]

If y = f(x), and y = a f(x) is a vertical stretch or compression, a > 1 causes the graph to be stretched vertically by a factor of a.
Answers
A vertical stretch in the context of graphing functions occurs when the function is multiplied by a positive constant greater than 1, resulting in the graph being stretched vertically by that factor without affecting the y-intercept.
A vertical stretch occurs when we multiply the function by a positive constant greater than 1. For example, if we have y = a f(x) and a is greater than 1, this results in the graph being stretched vertically by a factor of a. This type of transformation doesn't affect the y-intercept since the behavior of the graph at x=0 remains unchanged. Multiplying the independent variable by a constant such as 1/2 would result in a horizontal stretching or compression, but this is different from the vertical stretching effect we are discussing here.
Additionally, suppose the vertical stretch factor is a natural number. In that case, we can think of the stretched function as being the sum of the original function added to itself repeatedly that number of times. This additive property also extends to the derivative, as the derivative of the vertically stretched function is the original derivative multiplied by the stretch factor. This is known as the vertical stretch property in the context of derivatives and calculus.

What does it mean for an equation to have no solution or infinitely many solutions?
PLEASE GIVE ME A DETAILED RESPONSE AS IM TAKING MODULE 7 ALGEBRA DBA TOMORROW AT 7PM
Answers
If an equation has infinitely many solutions, all equations of x will make the equation true. For example, x+1=1+x.
No-Solution implies an inconsistent equation, while infinitely many solutions indicate a condition that holds true for any value of variable.
When an equation has No-Solution, it means that there is no value of variable that satisfies equation. In other words, equation represents an inconsistent condition, and solution set is empty. For example, equation 2x + 5 = 2x + 7 has no solution because the variable x cancels out, leaving an inconsistency (5 ≠ 7),
When an equation has infinitely many solutions, it means that any value of variable will satisfy equation. The equation represents a condition that is always true, regardless of chosen value.
For example, the equation x + 5 = x + 5 has infinitely many solutions because any value of x will make the equation true (such as x = 1, x = 2, x = 3, and so on).

What is the 30-60-90 right triangle?The 30-60-90 triangle is known as a special right triangle because its angles have a unique ratio of 1:2:3. Furthermore, the hypotenuse is twice the length of the shorter leg, and the larger leg is √3 times the length of the shorter leg.
For the given right-angled triangle, we can use the 30-60-90 rule. The 30-60-90 triangle is known as a special right triangle because its angles have a unique ratio of 1:2:3. Furthermore, the hypotenuse is twice the length of the shorter leg, and the larger leg is √3 times the length of the shorter leg.
Therefore, we can write,
PQ = 2(RQ)
8 = 2(RQ)
RQ = 4
PR = (RQ)√3
PR = 4√3
Hence, the length of the side PR in ΔPQR is 4√3 units.

I hope this helps!
The solution to the equation is y = 2 + 2x.
We have,
To solve the equation 6x - 3y = -6 for y, we can isolate the term with y by performing the following steps:
Start with the equation: 6x - 3y = -6.
To isolate the term with y, subtract 6x from both sides of the equation:
6x - 3y - 6x = -6 - 6x.
This simplifies to: -3y = -6 - 6x.
Next, divide both sides of the equation by -3 to solve for y:
(-3y) / -3 = (-6 - 6x) / -3.
This simplifies to: y = 2 + 2x.
Therefore,
The solution to the equation is y = 2 + 2x.

Answers
The formula for this is: a^2 + b^2 = c^2
So let the first side or a be .19
and the second side be .28
and now we are looking for c which is the missing side
.19^2 + .28^2 = c^20.0361 + 0.784 = .1145
get the square root of .1145
√.1145 = it is approximately 0.34
get the total distance by adding three sides
= .34 + .19 + .28
= 0.81
The total distance covered by her is 0.81 miles.
Given thatAlyssa is jogging near Central Park.
She runs along 65th Street for about 0.19 miles, turns right, and runs along Central Park West for about 0.28 miles.
She then turns right again and runs along Broadway until she reaches her starting point.
We have to determine
How long is her total run to the nearest hundredth of a mile?
According to the question
She runs along 65th Street for about 0.19 miles, turns right, and runs along Central Park West for about 0.28 miles.
Alyssa's route can be considered a right triangle with legs of length 0.19 and 0.28 (hundredths).
The total distance run is determined by using the Pythagoras theorem.
What is the Pythagorean theorem?Pythagorean theorem states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Therefore,
The distance run by her is,
[tex]\rm x^2 = (0.19)^2 +(0.28)^2\\\\ x^2=0.0361 + 0.784\\ \\ x^2 = .1145\\ \\ x= \sqrt{.1145} \\\\ x= 0.34[/tex]
Therefore,
The total distance covered by her is,
= .34 + .19 + .28
= 0.81 miles
Hence, the total distance covered by her is 0.81 miles.

Answers
Let m(BAE)=m(ACD)=α
(BAE and ACD are congruent, since they are alternate interior angles, or Z angles)
Let m(ABE)=β.
So in triangle ABE, the measures of the angles are 90, α and β degrees.
This means that m(BCE)=β, since the 2 other angles of triangle BCE are 90 and α degrees.
thus, we have the similarity of triangles ABE and BCE,
so the following rations are equal:
[tex] \frac{AB}{BC} = \frac{BE}{CE} = \frac{AE}{BE} [/tex]
so
[tex] \frac{AB}{BC} = \frac{x}{5} = \frac{8}{x} [/tex]
so
[tex]\frac{x}{5} = \frac{8}{x}[/tex]

Answer: Hello!
In the figure, Q and P are on opposite ends of the circle, and the same is for R and S, which means that the line that connects Q and P, or R and S, divides the circle in two equal halves. From this, we know that the angle between QoP is 180°, and the same for the angle RoS = 180°.
We also know that the angle RoP = 125°, then the angle between Q and R is the same as the angle between Q and P minus the angle between R and P.
this is : QoR = QoP - RoP = 180° - 125° = 55°
then QoR and RoP are supplementary angles, wich means that the addition adds up to 180°.
And is easy to see that the angles SoQ and PoS are reflexes of RoP and QoR respectively, then:
SoQ = 125° and PoS = 55°, where this angles also are supplementary.
