0.32 with the 2 repeating as a fraction

Answer:

Supplementary to x is a 90° angle (right angle) which means that both x and the right angle will have to equal 180 degrees:

90 + x = 180

-90        -90

x = 90°

Let's find the angle measure that is supplementary to y.

A 5 sided shape is equal to 540 degrees (you could find this by using the formula: (n - 2) x 180 where n is the number of sides)

so given interior angles:

90 + 80 + 98(supplementary to angle 82 degrees) + 136 + 136(two equal angle measures in the polygon that are missing)

= 540(which is correct), so now we know the two missing angles, 136, besides the angle supplementary to 82 degrees.

136 is supplementary to y so:

136 + y = 180

-136       -136

y = 44°

Answer:

17 rows

Step-by-step explanation:

We know that f(x) = 2x² - 10x models the total number of spaces and x models the number of rows.

Since we are given the total number of spaces of 408. We let f(x) = 408

2x² - 10x = 408

Now we solve as a quadratic, subtract 408 to both sides

2x² - 10x - 408 = 0

Divide 2 on both sides

x² - 5x - 204 = 0

We look for terms that multiply to -204 and add to -5.

Those terms are -17 and 12

x² - 17x + 12x - 204 = 0

x(x-17) + 12(x-17)

(x+12)(x-17)

x = -12 x = 17

We can not have -12 rows but we can have 17 rows.

17 rows is the answer.

Answer:

Step-by-step explanation:

We see that the triangle is isosceles as the two sides of it are 6.

In an isosceles triangle, you have two sides that are the same and two angles that are the same.

The two congruent angles will be opposite to the congruent sides.

So, we know that both angles must be x.

The Angles of a triangle add up to 180 degrees.

2x + 58 = 180

2x = 122

x = 61 ddegrees

Solution:

We know that:

We can see that the two lines of the triangle are equivalent.

This means that:

Equation created: 58 + x + x = 180

Simplify the LHS.

Subtract 58 both sides.

Divide 2 both sides.

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the cosine graph, if you plan on writing your equation as a function of sine, then by all means, go for it, but be careful and follow what is explained here. Now, as you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 100sin\:\frac{\pi}{50}x + 100,[/tex] in which you need to replase "cosine" with "sine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the cosine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the sine graph [photograph on the right] is shifted [tex]\displaystyle 25\:units[/tex]to the right, which means that in order to match the cosine graph [photograph on the left], we need to shift the graph BACKWARD [tex]\displaystyle 25\:units,[/tex]which means the C-term will be negative, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{-25} = \frac{-\frac{\pi}{2}}{\frac{\pi}{50}}.[/tex]So, the sine graph of the cosine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 100sin\:(\frac{\pi}{50}x + \frac{\pi}{2}) + 100.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [220, 100],[/tex]from there to [tex]\displaystyle [120, 100],[/tex]they are obviously [tex]\displaystyle 100\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 100.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 100,[/tex]in which each crest is extended one hundred units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

The graph of cosine function is to model the ride of your chosen rider.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Let us assume that,

Function is,

f(x) = sin(x)

The curve of the sine function crosses the y-axis at the origin, heads up to y = 1 at x = π/2 and down to y = -1 at x = 3π/2.

Domain: (-∞, ∞)

Range: [-1, 1]

For f(x) = cos(x)

The curve of the cosine function crosses the y-axis at (0, 1) which is its maximum, heads down to y = -1 at x = π then heads up again.

Domain: (-∞, ∞)

Range: [-1, 1]

Antoine and Adriane begin their journey at the top of the Ferris wheel.

After one revolution, they will again be at the top of the wheel.

If the wheel starts when time t = 0 seconds, and they begin their journey at the top of the wheel (the maximum point), the most appropriate graph to model their ride is the graph of the cosine function since it is at its highest point when x = 0.

Question :-

Answer :-

Explanation :-

As per the provided information in the given question, we have been given that a Rectangle has the Length as 15 cm and it's Breadth is given 20 cm . And, we have been asked to calculate the Area of Rectangle .

For calculating the Area of Rectangle , we will use the Formula :-

[tex] \bigstar \: \: \boxed {\sf {Area \: of \: Rectangle = Length \times Breadth}} [/tex]

Therefore , by Substituting the given values in the above Formula :-

⇒ Area of Rectangle = Length × Breadth

⇒ Area of Rectangle = 20 × 15

⇒ [tex] \textbf {\textsf {Area of Rectangle = 300 cm²}} [/tex]

[tex] \underline {\rule {180pt} {4pt}} [/tex]

The area of the given rectangle.

[tex]area = length \times width[/tex]

[tex]a = 15 \times 20[/tex]

[tex]a = 300 \: {cm}^{2} [/tex]

Therefore, the area of the given rectangle is 300 square centimeters.

The value of the function f(g) after simplifying and putting 2 in place of x is -20 and the value of f(g(2)) is 418.

When a function is written inside the another function, then such function is called the composite function.

The first function given in the problem is,

[tex]f(x) = x^2 - x - 2[/tex]

The second function given,

[tex]g(x) = - 6x - 8[/tex]

To find out the value of g(2), put the 2 on place of variable x in the above equation as,

[tex]g(2) = - 6(2) - 8\\g(2)=-12-8\\g(2)=-20[/tex]

The composite function f(g(x)) can be given as,

[tex]f(g(2))= (-20)^2 - (-20) - 2\\f(g(2))=418[/tex]

Thus, the value of the function f(g) after simplifying and putting 2 in place of x is -20 and the value of f(g(2)) is 418.
