What is the y-intercept of y 5x 10?

Answers

The y-intercept of y = 5x − 10 is -10.

If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.

The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, c, represents the y-coordinate of the point where the graph of the line intersects the y-axis.

Now, if we equate the standard slope-intercept form of the equation with the given equation, we get

y = mx + c

y = 5x - 10

m = 5 and c = -10

As we know the c is the y-intercept which is equal to -10.

You are standing next to a table and looking down on a record player sitting on the table. Take the spindle (axis of rotation) to be the center of your coordinate system and the y axis to be perpendicular to the side of the player you are standing next to. Long-playing records revolve 3313 times per minute. You put a small blob of clay at the edge of a record that has a radius of 0. 15 m, positioning the clay such that it is at its greatest value of y at t = 0.

Answers

Answer:

a) The rotational speed of the clay: 3.45 rad/s.

b) The value of A in the equation of motion: 0.15 m.

c) The value of ϕi: 90° or π/2 rad.

Given that;

Revolution per minute( rpm) is = 33( 1/3) =  100/3

The frequency ( f) is= 100 / 3(60) = 0.55 Hz

a) Rotational speed W = 2πf

we substitute

W = 2π × 0.55

W = 3.45 rad/s

So, the rotational speed of the clay is  3.45 rad/s.

b) given equation; y(t)=Asin(ωt+ϕi)

given that radius = 0.15 m

y(t)=(0.2)sin(ωt+ϕi)

So, the value of A in the equation of motion is 0.15 m.

c) since y(t) has the maximum value at t =0

so at t=0

y(0) = (0.15)sin(ω(0)+ϕi)

= 0.15sin(ϕi)

this gives maximum value when ϕi = 90°

so,

y(0) = (0.15)sin(ω(0)+ϕi)

= 0.15sin(90°)

= 0.15

So, the value of ϕi is 90° or π/2 rad.

The formula to find the position of an image is x = (width of the canvas - width of the image)/2 and y = (height of the canvas - height of the image)/2.

1. First, calculate the width of the canvas by subtracting the x-coordinate of the right side of the canvas from the x-coordinate of the left side.

2. Then, calculate the height of the canvas by subtracting the y-coordinate of the top side of the canvas from the y-coordinate of the bottom side.

3. Next, calculate the width of the image by subtracting the x-coordinate of the right side of the image from the x-coordinate of the left side.

4. Then, calculate the height of the image by subtracting the y-coordinate of the top side of the image from the y-coordinate of the bottom side.

5. Finally, calculate the x-coordinate of the position of the image by dividing the width of the canvas by two and subtracting the width of the image from that result.

6. Calculate the y-coordinate of the position of the image by dividing the height of the canvas by two and subtracting the height of the image from that result.

Therefore, the formula for finding the position of an image is x = (width of the canvas - width of the image)/2 and y = (height of the canvas - height of the image)/2.

A linear equation in one variable is an equation in which the highest power of the variable is 1. A linear equation in one variable can be written in the form of y = mx + b, where m is the slope and b is the y-intercept. The graph of a linear equation in one variable is a straight line.

In the given problem, the rental cost of a mid-sized car from Eliana's Rentals can be represented by the equation:

y = 60 + 6x (where y is the total cost and x is the number of days)

The rental cost of a mid-sized car from Arcadia Rent-a-Car can be represented by the equation:

y = 30 + 12x (where y is the total cost and x is the number of days)

At some point, renting from either one of the companies would cost the customer the same amount, so we can set both equations equal to each other and solve for x:

60 + 6x = 30 + 12x

Solving for x:

30 = 6x

Lisa makes $30 for 4 hours of babysitting. Write an equation to represent her earnings, e, relative to the number of hours, h, that she works. Assume the relationship is proportional.

Answers

Answer: e = 7.5*h

Step-by-step explanation: The relationship between Lisa's earnings, e, and the number of hours, h, that she works is proportional. This means that the ratio of e to h is constant. One way to represent this relationship is through an equation of the form:

e = k*h

where k is a constant of proportionality. In this case, we know that Lisa earns $30 for 4 hours of babysitting, so we can use this information to find the value of k:

30 = k*4

k = 30/4 = 7.5

So the equation that represents Lisa's earnings, e, relative to the number of hours, h, that she works is:

e = 7.5*h

Where e is the earnings and h is the number of hours and 7.5 is the constant of proportionality.

Alternatively, you can write the equation as e = 30/4 * h = 7.5 * h

This equation tells us that for every hour that Lisa babysits, she earns $7.5.

What triangle is formed when the sides are 5/12 13?

Answers

The triangle formed when the sides are 5, 12, 13 is a right-angled triangle. The Pythagorean theorem can be used to verify this.

From Pythagorean theorem, it can be said that, the square of hypotenuse side is equal to the sum of other two sides of a right angled triangle.

Let AB, CA and BC be the sides of a right triangle. CA is the hypotenuse side, AB and BC are the base and height sides of the right triangle. The equation can then be expressed as,

CA² = AB² + BC²

Now, let us check this rule for the above given sides of the triangle.

Longest side² = Sum of squares of other two sides

13² = 12² + 5²

169 = 144 + 25

169 = 169

Thus, the sides 5 cm, 12 cm and 13 cm can form a right-angled triangle.

____relate the side lengths of a right triangle to an acute angle

Answers

Sine function relates side lengths of a right triangle to an acute angle.

In a right triangle, the side lengths are related to the acute angles through the trigonometric functions. The side opposite the acute angle is related to the angle through the sine function, the side adjacent to the acute angle is related to the angle through the cosine function, and the hypotenuse is related to the angle through the tangent function.

More specifically, if θ is an acute angle in a right triangle and a and b are the lengths of the side opposite and adjacent to the angle respectively, and c is the length of the hypotenuse, we have:

sin(θ) = a/c

cos(θ) = b/c

tan(θ) = a/b

Thus, we can use these functions to find the length of any side of the right triangle if we know the measure of one of the acute angles and the length of one of the other sides.

what is sequence ?

A collection of numbers, or "terms," is referred to as a sequence. Examples of terms include 2, 5, and 8. Some sequences can be made endlessly long by taking advantage of a particular pattern they follow. Use the example of 2,5,8 and add 3 to continue the series. There are formulas that demonstrate where to look for words within a sequence. A collection of objects that are in some order is known as a sequence in mathematics (or events). It resembles a set in that it has pieces (also called elements or terms). the act of placing two or more items in a logical order. Chronological.

How to solve factor by grouping. Step by step.

Answers

solving factor by grouping, The final factored form of the expression is n(n + 3) - 10.

What is factor?

A factor is a number that divides into another number exactly with no remainder. For example, the factors of 8 are 1, 2, 4, and 8.

What is factor by grouping?

Factor by grouping is a method of factoring polynomials, which is used to find the common factors in an expression. The idea is to group the terms of the polynomial in such a way that the common factors can be factored out of them. In other words, it is a way to simplify an algebraic expression by finding common factors among the terms and then grouping them together. For example, the polynomial 2x^2 + 6x can be factored by grouping as (2x^2 + 6x) = 2x(x + 3). This is the most common way to factor a polynomial with four terms.

To solve the problem "factor by grouping" for the expression "n^2+3n-10", you can follow these steps:

Write the expression in the form of (n^2 + An + B) + (Cn + D)

(n^2 + 3n - 10) = (n^2 + 3n) + (-10)

Factor out the greatest common factor (GCF) of the terms in the first set of parentheses.

(n^2 + 3n) = n(n + 3)

Factor out the GCF of the terms in the second set of parentheses, if possible. In this case, there is no GCF.

Combine the factored expressions from step 2 and step 3 to get the final factored form.

n(n + 3) + (-10)

The final factored form of the expression is n(n + 3) - 10.

Barry draws the model below and it says it proves that 1,243 divided 3 = 481. What mistake does Barry make?

Answers

Barry mistakes that dividing 1,243 by 3 would yield 481. This is not the case, because 1243/3 = 414.33.

The mistake that Barry made is that he most likely used simple long division method, but forgot to carry over the decimal number.

Another mistake could be the misreading of the problem, thinking that the 1,243 is the quotient, while in reality it is the dividend.

The Persians landed in the plains near Athens. As their army greatly outnumbered that of the Greeks, the Greeks hoped to find aid from nearby Sparta. A long-distance runner named Pheidippides was sent from Athens to Sparta to request help, but the Spartans were not able to send more soldiers at the time. Regardless, the Greeks were still able to win the battle. Centuries later, legend developed that a runner had been sent from the battle to Athens after the Greek victory. After reaching Athens, the runner proclaimed, "We are victorious!" and then fell to the ground and died. This legendary story is the inspiration for the modern long-distance runs that are performed today.This passage refers to the events of which battle during the Persian Wars? A.
