Answers

Answer 1

1/10  fraction of the circumference of the circle .

What is arc?

An arc is any straight line that connects two locations. The term "arc length" refers to an arc's length. An ordered pair of adjacent vertices is referred to as a graph arc in a graph.

                        Any section of the circle's circumference (other than the entire curve) is referred to as an arc.

C = 2πr

C - circumference of a circle

r - radius of a circle

r =  4

Then

C = 2π • 4 = 8π

Writing the fraction:

e) m = [tex]\frac{2}{3}[/tex] , b = -4

What do you mean by equation of line?

A line equation is an algebraic representation of a set of points that together form a line in a coordinate system. A number of points that together form a line of axes, represented as a set of variables x,y, form an algebraic equation called the line equation.

Slope intercept form of the line is y = mx - b where m is the slope of the line and b is the x-intercept

a) y = 2x + 3

On comparing the equation with y = mx - b, we get m = 2 , b = -3

b) 2y = -3x -4

⇒ y = [tex]\frac{-3x}{2}[/tex] - 2

On comparing the equation with y = mx - b, we get m = -3/2 , b = -2

Person B pays $33.93 to download 4 individual songs and 3 albums. Write a system of linear equations that represents this situation. How much does the website charge to download a song? an entire album???

Answers

Answer:

1/ y= -3x + 12.96

2/ $9.99 for an entire album & $0.99 for a song

Step-by-step explanation:

We know that the

The amount charged for downloading individual songs = x dollars

And the amount charged for downloading an entire album = y dollars

Let's write a function for person A first

6x + 2y = 25.92

Solve, and we will get

y = -3x + 12.96

Now to person B

4x + 3y = 33.93

Putting the value of y from the first equation in the second

4x + 3(12.96 - 3x) = 33.93

- 5x = - 4.95

x = $0.99

Then we take

y = 12.96 - 3x

= 12.96 - 2.97

= $9.99

Which equation choice could represent the graph shown below?

Answers

The function representing the graph is f(x) = (x + 5)²(x - 3)². The correct option is (a).

What is a function?

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

The given graph of the function cuts x axis at (-5,0) and (3,0) and y axis at (0,225) respectively.

Since the zeros of a function is the point at which it cuts the x-axis, the zeros at of the given functions are -5 and 3.

Which implies that the factors are (x + 5) and (x - 3) respectively.

The given factors are valid for options (a) and (d).

Now, at x = 0 f(x) should be 225.

It can be checked for both the options as follows,

(a) f(x) = (x + 5)²(x - 3)²

=> f(0) = (0 + 5)²(0 - 3)²

           = 5² × -3²

What in math is a rate?

A rate is a unique ratio where the two words are expressed in several units. For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. This ratio compares two dissimilar units: ounces and cents

A = A(r(t))

The chain rule can be used to resolve this kind of issue.

Rate of area change:
