Answer:

Step-by-step explanation:

Tracey Earns in week= $102.45

Tracy=2x-12.45

102.45=2x-12.45

2x= 102.45+12.45

2x=114.90

x= 114.90/2

x=$57.45

Kayla earns 57.45 dollars

The equation is n = (102.45 + 12.45) x 2.

And Kayla earns $229.8.

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given:

In a week, Tracey earns $12.45 less than twice the amount Kayla earns. Tracy earns $102.45.

Let n be the amount Kayla earns.

Then,

Kayla earns,

n = (102.45 + 12.45) x 2

n = $229.8

Therefore, Kayla earns $229.8.

Answer:

C

Step-by-step explanation:

In translating graphs of functions, we can follow 2 rules:

1. The graph of  [tex]f(x)+a[/tex] is the graph of  [tex]f(x)[/tex] shifted a units UP VERTICALLY and the graph of   [tex]f(x)-a[/tex] is the graph of  [tex]f(x)[/tex] shifted a units DOWN VERTICALLY.

2. The graph of  [tex]f(x+a)[/tex]  is the graph of   [tex]f(x)[/tex]  shifted a units to the LEFT HORIZONTALLY and the graph of  [tex]f(x-a)[/tex]  is the graph of  [tex]f(x)[/tex]  shifted a units RIGHT HORIZONTALLY.

If we understand the 2 rules above, we clearly know that f(x+2) will be a horizontal shift to the LEFT, of course, with respect to the function  [tex]f(x)=x^3[/tex]. Looking at the answer choices, C is right.

x(x^3/x + x^2/x + -6x/x)

x(x^2 + -6)

x(x - 2)(x + 3)

Answer:

x(x + 3)(x - 2)

Step-by-step explanation:

Factor out x from each term

= x(x² + x - 6)

To factor the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x - term (+ 1)

The factors are + 3 and - 2, since

+ 3 × - 2 = - 6 and + 3 - 2 = + 1, hence

x² + x - 6 = (x + 3)(x - 2)

---------------------------------------

x³ + x² - 6x = x(x + 3)(x - 2) ← in factored form

Answer:

145°

Step-by-step explanation:

The angle is 90°+55°=145°

Answer: 145°

Step-by-step explanation:

The angle of straight lines is always 180°, so I took 180 and subtracted 55 from it, and then 90 to get 35. I got 90 because the x and y axis are perpendicular to each other, and the angle between perpendicular lines is always 90. 35° is the angle of the small un marked section to the left of the circles, so to get the angle of the circle-like line, I did 180-35 to get 145°.

Answer:

$2280

Step-by-step explanation:

I see you've already found part a, which is to find the amount of interest earned. The next part is easy, to find the balance of the account after four years, just add the interest you've found back to the principal (the original size of the account or loan). $2000 + $280 equals $2280.

The interest earned on the account is $280. The balance of the account after 4 years is $2280.

To find the interest earned on the account, we use the formula for simple interest:

I = PRT

where:

Substituting the given values:

I = $2000 * 3.5/100 * 4 = $280

To find the balance of the account, we add the interest earned to the principal:

Balance = P + I = $2000 + $280 = $2280

Answer:

[tex](2,200\pi +8,000)\ ft^{3}[/tex]

Step-by-step explanation:

we know that

The volume of the figure is equal to the volume of cube plus the volume of the cylinder

step 1

Find the volume of the cube

The volume of the cube is equal to

[tex]V=b^{3}[/tex]

we have

[tex]b=2(10)=20\ ft[/tex] ----> the length side of the cube is equal to the diameter of the cylinder

so

[tex]V=20^{3}=8,000\ ft^{3}[/tex]

step 2

Find the volume of the cylinder

The volume of the cylinder is equal to

[tex]V=\pi r^{2} h[/tex]

we have

[tex]r=10\ ft[/tex]

[tex]h=42-20=22\ ft[/tex]

substitute

[tex]V=\pi (10)^{2} (22)[/tex]

[tex]V=2,200\pi\ ft^{3}[/tex]

step 3

The volume of the figure is equal to

[tex](2,200\pi +8,000)\ ft^{3}[/tex]

The volume of the figure = volume of oblique cylinder + volume of cube = 2,200π + 8,000 cubic feet.

Volume of oblique cylinder = πr²h [radius of cylinder = r].

The volume of the figure = volume of oblique cylinder + volume of cube = πr²h + s³

Given the following:

Plug in the values into πr²h + s³:

The volume of the figure = π(10²)(22) + 20³

The volume of the figure = 2,200π + 8,000 cubic feet.

Step-by-step explanation:h=2 A/b meaning h=2 67.5/9

Answer:

h = 15 meters

Step-by-step explanation:

The area of a triangle is determined by its height multiplied by its base.

The equation is A = 1/2*bh.

Plugging in the numbers gives us 67.5 = 1/2*9h.

Dividing by 4.5 in both sides gives us that h = 67.5/4.5 = 15 meters.

Answer:

option C is the correct answer

Step-by-step explanation:

The trigonometric equation you are using has a general form

y = A* tan w*(x - r)

A is the amplitude of the function

w is the frequency rad/s

r  is the phase shift

In your case

A = -2

Equation: $21.50•n=c

Answer:

7

Step-by-step explanation:

This is an equation of an ellipse of the form:

[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]

Where a and b are the minor and major intercepts, given a<b

In this question, a<b and a = 3 and b = 7

The distance from the center to the major intercept is b, thus the distance we are seeking for is 7

Answer:

b = 7 units.

Step-by-step explanation:

The given equation of the ellipse is

[tex]\frac{x^{2} }{9} +\frac{y^{2} }{49}=1[/tex]

As we know in an ellipse  [tex]\frac{x^{2} }{a^{2} }+ \frac{y^{2} }{b^{2}}=1[/tex]

a will be major axis and b is the minor axis when ( a > b )

In the given equation 49 > 9 ⇒ b² > a²

so major axis will be = √49

                                  = 7

Therefore, distance from center to the major intercept is b = 7 units.

Answer:

The product of the slopes of line a and line is -1.

Perpendicular lines a and b intersect at a right angle, or 90 degrees. This is independent of whether they are increasing or decreasing, or their steepness on a graph.

The statement about lines a and b that is true when they are perpendicular is that they form a 90-degree angle with each other. The concept of perpendicularity in geometry refers to lines, planes, or surfaces that intersect at a right angle.

Terms like increasing or decreasing line or the steepness of a line do not apply here as they pertain to the slope of the line in the context of a graph, which is distinct from the concept of perpendicularity.

For example, saying line A is a decreasing line while line B is an increasing line, does not describe their perpendicular relationship. Instead, they intersect or meet at a right angle (90 degrees), proving their perpendicular nature.

To find the slope of a line passing through the origin and a point, use the formula slope = (y2 - y1)/(x2 - x1). For a line passing through origin and the point (-8,-5), the slope is 5/8.

The topic at hand revolves around the concept of slope and the algebra of straight lines. The slope is calculated by finding the change in y (vertical axis) over the change in x (horizontal axis). To find the slope of a line passing through the origin and the point (-8,-5), use the formula slope = (y2 - y1)/(x2 - x1).

In this case, the origin is point (0,0) and the given point is (-8,-5). So to find the slope, we substitute these values into the slope formula: slope = (-5 - 0)/(-8 - 0) = 5/8. Therefore, the slope of the line passing through the origin and the point (-8,-5) is 5/8.

The slope of a line, denoted by m, represents the rate of change between the vertical and horizontal components of two points on the line.

To find the slope of a line passing through the origin and intersecting the point (-8, -5), we can use the slope formula. The slope formula is given by: m = (y2 - y1) / (x2 - x1).

Plugging in the values from the given point gives: m = (-5 - 0) / (-8 - 0)

The area of a rectangle with length 4x^3 and width 5 is expressed as the monomial 20x^3 by multiplying the length and width.

To express the area of a rectangle as a monomial when given the length and width, we simply need to multiply these two dimensions together. In this case, the rectangle has a length of 4x^3 and a width of 5. The area (A) of a rectangle is given by the formula A = length * width.

So, the area of this rectangle can be calculated as:

A = 4x^3  * 5

Now, we multiply the numerical coefficients (4 and 5) and then combine them with the variable part:

A = (4 * 5) x^3

A = 20x^3

This expression, 20x^3, represents the area of the rectangle as a monomial

p(x) * r(x) = ab^x * cd^x
