$39.99. It is on sale for 30% off.
The taxes are 16%. What is the sale
price of the skateboard including taxes?
A student says, “$39.99 – 30% discount
+ 16% taxes is the same as calculating
$39.99 – 14%.”
Is the student’s reasoning correct?

Answer:

267,168 inches

Step-by-step explanation:

If your box is a rectangular prism or a cube, the only information you need is the box's length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated as V = l x w x h.

Volume = L × W × H

Where,

Volume = 22 inches × 12 inches × 1012 inches

Volume = 267,168 inches

So, her cooler can hold 267,168 inches of ice

The transformation that takes place on the parent function ( f (x) = log (x) ) to achieve the graph of g(x)=log(-3x+9)+4  can be described as a reflection across the y-axis. Then you horizontally shrink a factor of three; shift three units to the right, and shift four units upwards.

Step 1: The parent graph is to be translated 3 units to the right side to achieve: y = log (x-3)

2. Shrink the graph by a factor of three by multiplying x by three:

⇒ y = log 3(x-3)

3. Reflect the function y = log 3(x-3) across line -3 = x to achieve:
y = -3(x-3)

4. Translate the function y = log 1-3(x-3) four units upwards to achieve

y = log (-3 + 9) +4

well, the tell-tale part in the points will be the coordinates, hmmm now, the x-coordinate for both points is the same, well, that simply means is a vertical line.  Check the picture below.

By the Law of Sines,

[tex]\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \sin B=\frac{b \sin A}{a} \\ \\ =\frac{244\sin 37.8^{\circ}}{229} \\ \\ B \approx 37.42^{\circ}, 142.58^{\circ}[/tex]

Of these, only 37.42° is a possible value of B (sum of angles of a triangle is 180°).

So, we have that:

[tex] a=229, b=244, A=37.8^{\circ}, B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]

Angles of a triangle add to 180°, so:

[tex]C=180^{\circ}-A-B=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)

[/tex]

Using the Law of Sines again,

[tex]\frac{c}{\sin C}=\frac{a}{\sin A} \\ \\ c=\frac{a \sin C}{\sin A} \\ \\ =\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}}[/tex]

So, there is one possible triangle, where:

[tex]a=229 \\ \\ b=244 \\ \\ c=\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}} \\ \\ A=37.8^{\circ} \\ \\ B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right) \\ \\ C=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]

n is the number of chirps per minute.

Step-by-step explanation:

The equation y = 2x² - 12x + 23 describes the function graph that includes a vertex at (3, 5) and passes through the point (5, 13).

The vertex of a parabolic equation is at the point and the vertex form is y = a(x - h)2 + k, where a, h, and k are constants (h, k).

Find the function whose graph has the vertex at (3, 5) and passes through the point in the question (5, 13).

Assuming it to be a parabolic function, we know that a parabolic equation's vertex form is y = a(x - h)2 + k, where a, h, and k are constants, and the vertex is located at the position (h, k).

As the vertex of the necessary function is at the position (3, 5), we may substitute h = 3 and k = 5 to obtain the following equation in the above equation:

y = a(x - 3)² + 5

Now that we know that the graph passes through the point (5, 13), we can change the original equation to read:

13 = a(5 - 3)² + 5,

or, 13 = 4a + 5,

or, 4a = 13 - 5 = 8,

or, a = 2.

We obtain the following from the equation y = a(x - h)2 + k by inserting a = 2, h = 3, and k = 5:

y = 2(x - 3)² + 5,

alternatively, y = 2(x² - 6x + 9) + 5,

alternatively, y = 2x² - 12x + 18 + 5,

Alternatively, y = 2x² - 12x + 23.

As a result, the function graph with the vertex at (3, 5) and the point of intersection (5, 13) yields the equation y = 2x² - 12x + 23.

Answer:

width=x

length=5x

area= 300ft2

area=lxb

300=5x(x)

300=5x^2

x^2=60

x=7.74

7.74(5)=38.7

dimensions are 38.7ft by 7.74 ft

Please mark as brainliest

Step-by-step explanation:

the area of a rectangle is

length × width = 300 ft²

length = width + 5

(width + 5) × width = 300

width² + 5×width = 300

width² + 5×width - 300 = 0

the general solution to such a quadratic equation is

width = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 5

c = -300

width = (-5 ± sqrt(5² - 4×1×-300))/(2×1) =

= (-5 ± sqrt(25 + 1200))/2 =

= (-5 ± sqrt(1225))/2 = (-5 ± 35)/2

width1 = (-5 + 35)/2 = 30/2 = 15 ft

width2 = (-5 - 35)/2 = -40/2 = -20 ft

negative lengths for an actual object don't make sense, so width = 15 ft is our solution.

length = width + 5 = 15 + 5 = 20 ft

The unknow angles are as follows:

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.

Therefore,

m∠4 = 72 degrees

Hence,

m∠1 + m∠4 = 180 (angle on a straight line)

m∠1 = 180 - 72

m∠1 = 108 degrees

m∠2 = m∠4 (vertically opposite angles)

Vertical angles are the angles formed when two lines intersect each other. Vertical angles are congruent.

Therefore,

m∠2 = 72 degrees

m∠5 = m∠1 (corresponding angles)

Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.

m∠5 = 108 degrees.

m∠7 = m∠5(vertically opposite angles)

m∠7 = 108 degrees

m∠8 = m∠2 (alternate exterior angles)

Alternate exterior angles are congruent.

m∠8 = 72 degrees

Answer: y = -3x + 6

Step-by-step explanation:

If it is perpendicular to the line -3x + 2, then it's slope should also be -3.

The standard form of a line is y = mx + b. As our slope is -3, we have that our line is y = -3x+b. Now, let's put the given point into the line. x = 3 and y = -3, so -3 = -3*3 + b. Hence, b = -3+9 = 6. The equation of the line is y = -3x + 6.

Answer:

-1/4 Abs(x+12) + 10

Step-by-step explanation:

The vertex form of an absolute function is of the form
y = a|x -h| + k   here |x-h| is the absolute value
where (h, k) are the coordinates (x, y) of the vertex

The vertex is given as (-12, 10)

So h = -12, k = 10

Plugging these in we get the vertex form as

y = a|x - (-12)| + 10

y = a|x + 12| + 10

All it remains is to find a

Given point (4, 6) as a point on the graph, plug these values
y = 6 = a|4 + 12| + 10

6 = a|16| + 10

6 = 16a + 10      since absolute value of a positive number is the number

Switch sides
16a + 10  = 6

Subtract 10 from both sides:
16a + 10 - 10 = 6 - 10
16a = -4
a = -1/4

So the equation of the function is
y = -1/4|x + 12| + 10

The second point is not needed to derive the function equation but let's use it to verify our calculated equation

Point (-8, 9)
Plug x = -8,  into y = -1/4|x + 12| + 10

=> y = -1/4|-8+12| + 10
=> y = -(1/4)·4 + 10

=> y = -1 + 10

= y = 9 which matches with the y -coordinate of the second point

So everything looks cool

Final Solution
-1/4 Abs(x+12) + 10

Graph A, and graph C could not possibly be density curves for a continuous random variable if they were provided with the right scale.

A symbol (often a letter) used in algebra to represent an unknowable numerical value in an equation. Variables can have a wide range of values, which is why they are called variables. Thus, a variable can be thought of as a quantity that can take on different values depending on the circumstances of a given issue. As the program executes, we may store, modify, and access this data thanks to variables. All types of information can be stored in variables.

Four graphs of different nature as options.

We are required to find a graph that is not a continuous variable.

In mathematics, a continuous function is a function such that a continuous variation of the argument induces a continuous variation of the value of the function.

Continuous lines are those lines that when decreased, decrease with continuity and when increased, increase with continuity.

Given that,

When we observe graph A, graph C. In these graphs, the value of the function keeps increasing and decreasing a lot and is not in continuity.
