(a) write down two numbers from the list that add up to -9

Answer:

y = 4x - 27

Step-by-step explanation:

Parrel lines have the same slope

Point-Slope Form:

(6, -3)

y - y1 = m(x - x1)

y - (-3) = 4(x - 6)

y + 3 = 4x - 24

 - 3         -3

y = 4x - 27

Hope this helps!

This shows that both functions have the same y-intercept

Given the following functions as shown:

f(x) = -x^2 + 2x + 1

g(x) = 2^x

The y-intercept occurs at x = 0

For f(x) =  -x^2 + 2x + 1

f(0) =  -0^2 + 2(0) + 1

f(0) = 1

For the g(x),  the y intercept is caculated as:

g(0) = 2^0
g(0) = 1

This shows that both functions have the same y-intercept

The factorization of [tex]9x^2 - 81[/tex] is given 9(x-3)(x+3). Therefore, (c) is the correct option.

Factorization is the method of simplification of algebraic expressions which contains variables and constants into form that can not be divided into further factors.

To factorize, we first check if any variable or constant can be taken common. Next we check for algebraic identities.

Given in the question,

[tex]= 9x^2 - 81\\\\= 9(x^2 - 9)\\\\=9(x^2-3^2)\\\\=9(x-3)(x+3)[/tex]

identity used : [tex](a^2-b^2) = (a-b)(a+b)[/tex]

Step-by-step explanation:

The first step is to calcuate inside perthenses .

The second step is to find value of expontents.

The third step is to add then subtract.

The fourth step is to multiply.

Answer:

307/500

Step-by-step explanation:

307 is a prime number.

The way to find this out is to take 0.614 and multiply it by 1,000 because then it will be a natural number. 0.614*1,000=614.

now you take 614/1,000 because that's what you multiplied it by and simplify it.

614/2 and 1,000/2=307/500 and this cannot be simplified any more than this because 307 is a prime number.

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:

4.0 cm

Step-by-step explanation:

The volume of the frustum is the volume of the full cone (with height y + 7) minus the volume of the upper smaller cone (with height y).

Formula:

volume of cone = (1/3)πr²h

For the full cone:

r = 8 cm

h = y + 7

volume of cone [in cm³] = (1/3)π(8²)(y + 7)

volume of cone [in cm³] = (1/3)π(64)(y + 7)

volume of cone [in cm³] = (64π/3)(y + 7)

For the upper cone:

volume of cone = (1/3)πr²h

volume of cone = (1/3)π(4²)y

volume of cone = (16π/3)y

For the frustum:

volume = volume of full cone - volume of upper cone

volume = (64π/3)(y + 7) - (16π/3)y

volume = 64πy/3 + 448π/3 - 16πy/3

volume = 48πy/3 + 448π/3

Now we solve for y:

48πy/3 + 448π/3 = 670.2

50.265y + 469.144 = 670.2

50.265y = 201.056

y = 4.0

There is no value of x that makes the equation be true since an absolute value can never be negative.

[tex]\displaystyle y = 100sin\:(\frac{\pi}{50}x + \frac{\pi}{2}) + 100 \\ y = 100cos\:\frac{\pi}{50}x + 100[/tex]

Step-by-step explanation:

[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 100 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-25} \hookrightarrow \frac{-\frac{\pi}{2}}{\frac{\pi}{50}} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{100} \hookrightarrow \frac{2}{\frac{\pi}{50}}\pi \\ Amplitude \hookrightarrow 100[/tex]

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]

Given information:

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.

Step-by-step explanation:

24: 18

Divide each side by 6

24/6 : 18/6

4 : 3

Answer: 4:3

Step-by-step explanation: so firstly we will see the common factors of 24 and 18.

the factors of 24 is 1, 2, 3, 4, 6, 8, 12, 24

the factors of 18 is 1, 2, 3, 6, 9, 18

we can see that the common factors are 1, 2, 3, 6

so the largest common factor is 6

so you divide 24 by 6 and that will give you 4

then you divide 18 by 6 and it will give you 3

so 24:18 simplify =4:3

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.
