Answer:

[tex]\frac{4}7[/tex]

Step-by-step explanation:

Just as a reminder, to find the ratio of 2 numbers, you divide the first by the second, and to divide 2 fractions, you multiply the dividend by the reciprocal of the divisor.

In this case, that would be:

[tex]\frac{\frac{4}{5}}{\frac{7}{5}}[/tex]

[tex]= \frac{4}{5} \cdot\frac{5}{7}[/tex]

=[tex]\frac{4}7[/tex]

Answer:

If you're multiplying then the answer would be  B.

Step-by-step explanation:

If you multiply two negative numbers, your product would be positive.

If you multiply 1 positive and 1 negative then your product will be negative.

Point :

Parallel lines have same slopes.

_________________________________

[tex]6x + 5y = 11[/tex]

Subtract sides -6x

[tex] - 6x + 6x + 5y = - 6x + 11[/tex]

[tex]5y = - 6x + 11[/tex]

Divided sides by 5

[tex] \frac{5}{5}y = \frac{ - 6}{5}x + \frac{11}{5} \\ [/tex]

[tex]y = - \frac{6}{5}x + \frac{11}{5} \\ [/tex]

Look :

This is the slope-intercept of the given line. We know that the coefficient of x is the slope of the linear functions in slope-intercept form.

Thus the slope of the line which we want is :

[tex]slope = - \frac{6}{5} \\ [/tex]

_________________________________

We have following equation to find the point-slope form of the linear functions.

[tex]y - y(given \: point) = (slope) \times (x - x(g \: p) \: ) \\ [/tex]

Now just need to put the slope and the coordinates in the above equation.

[tex]y - ( - 8) = - \frac{6}{5} \times (x - ( - 2) \: ) \\ [/tex]

[tex]y + 8 = - \frac{6}{5}(x + 2) \\ [/tex]

To find the slope-intercept form of the above equation we need to take the y alone and then simplifies the equation.

Look :

[tex]y + 8 = - \frac{6}{5}x - \frac{12}{5} \\ [/tex]

Subtract sides by -8

[tex]y + 8 - 8 = - \frac{6}{5}x - \frac{12}{5} - 8 \\ [/tex]

[tex]y = - \frac{6}{5}x - \frac{12}{5} - \frac{40}{5} \\ [/tex]

[tex]y = - \frac{6}{5}x - \frac{52}{5} \\ [/tex]

This is what we want...

_________________________________

Now we must Check the equation by using the given point :

[tex]( - 8) = - \frac{6}{5}( - 2) - \frac{52}{5} \\ [/tex]

[tex] - 8 = \frac{12}{5} - \frac{52}{5} \\ [/tex]

[tex] - 8 = \frac{ - 52 + 12}{5} \\ [/tex]

[tex] - 8 = \frac{ - 40}{5} \\ [/tex]

[tex] - 8 = - 8[/tex]

So the equation is right.

Answer:

C. 128 in²

Step-by-step explanation:

We know that the opposite sides of rectangles are congruent, so 8 = 2x. If we divide 8 by 2 and 2x by 2, we get x = 4.

Now, the area of a rectangle is l × w, where l = length and w = width. The dimensions of this rectangle are 8 and 16, so 8 × 16 = 128 in².

Answer:

[tex]\displaystyle \boxed{y = -3} \\ \boxed{\pi} \\ \boxed{N/A} \\ f(x) = \boxed{-2cot\:(x + \frac{\pi}{2}) - 3}[/tex]

Step-by-step explanation:

[tex]\displaystyle f(x) = Acot(Bx - C) + D \\ \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{\pi}{B} \\ Amplitude \hookrightarrow |A| \\ \\ \\ Vertical\:Shift \hookrightarrow -3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-\frac{\pi}{2}} \hookrightarrow \frac{-\frac{\pi}{2}}{1} \\ Wavelength\:[Period] \hookrightarrow \frac{\pi}{2} \\ Amplitude \hookrightarrow N/A[/tex]

OR

[tex]\displaystyle f(x) = \boxed{2tan\:x - 3} \\ \\ f(x) = Atan(Bx - C) + D \\ \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{\pi}{B} \\ Amplitude \hookrightarrow |A| \\ \\ \\ Vertical\:Shift \hookrightarrow -3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{\pi}{2} \\ Amplitude \hookrightarrow N/A[/tex]

Here is all the information you will need. Now, what you need to know is that ALL tangent, secant, cosecant, and cotangent functions have NO amplitudes. Also, keep in mind that although this IS a tangent graph, if you plan on writing your equation as a function of cotangent, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle f(x) = 2cot\:x - 3,[/tex]in which you need to replase "tangent" with "cotangent", then figure the appropriate C-term out that will make the graph horisontally shift and map onto the tangent 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 graphs, we can tell that the cotangent graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{2}\:unit[/tex]to the right, which means that in order to match the tangent graph [photograph on the left], we need to shift the graph BACKWARD [tex]\displaystyle \frac{\pi}{2}\:unit,[/tex]which means the C-term will be negative, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{-\frac{\pi}{2}} = \frac{-\frac{\pi}{2}}{1},[/tex]but we are NOT YET DONE. Although we shifted the graph back into position, remember, cotangent is graphed in REVERCE, so we need to insert a negative in front of the amplitude term, and with that, the cotangent graph of the tangent graph, accourding to the horisontal shift, is [tex]\displaystyle f(x) = -2cot\:(x + \frac{\pi}{2}) - 3.[/tex]Now, with all that being said, we can move forward. To find the period in this case, you need to take a look at the distanse between each vertical asymptote. Now, accourding to this graph, the vertical asymptotes are at [tex]\displaystyle -\frac{\pi}{2} = x\:and\:\frac{\pi}{2} = x.[/tex]From here, you will then find the distanse between these asymptotes by simply perfourming the operation of Deduction, and doing that will give you [tex]\displaystyle \boxed{\pi} = \frac{\pi}{2} + \frac{\pi}{2}.[/tex]So, the period of this function is [tex]\displaystyle \pi.[/tex]Now, you will instantly get the jist of the horisontal shift by looking at the above formula. Just keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to what is given to you inside those parentheses. Finally, the midline is the centre of your graph, also known as the vertical shift, which in this case is at [tex]\displaystyle y = -3.[/tex]

Well, that just about wraps it up. Now that everything has been explained, you should understand it better. If you still have questions, do not hesitate to comment any you have.

The quantity of paint required to paint the platform is 3 gallons.

The space occupied by any two-dimensional figure in a plane is called the area. Here we have three shapes a triangle, a rectangle and a parallelogram.

Given that the attached figure represents a platform in an auditorium. The crew needs to paint it green. One gallon of paint will cover 40 square yards. One gallon of paint will cover 40 square yards.

The area of the platform is,

Area = (3x2) + 2 ( 7x 2 ) + ( 4 x 2 )2 + 3(6) + ( 5 x 3 ) + ( 4 x 3 ) + ( 2 x 3 ) + ( 7 x 3 )

Area = 6 + 28 + 16 + 18 + 15 + 12 + 6 + 21

Area = 122 square yards.

The quantity of paint required will be calculated as,

Q = 122 / 40

Q = 3 gallons

Answer:

The explicit formula is [tex]a_n=15(\frac{4}{5})^{n-1}[/tex].

Step-by-step explanation:

First, we need to find the common ratio. We know this is a geometric sequence because the decrease from one term to the next is not a constant number.

To find the constant ratio, we can take the [tex]2^{nd}[/tex] term and divide by the [tex]1^{st}[/tex] term:

[tex]\frac{2nd}{1st}=\frac{12}{15}=\frac{4}{5}[/tex]

So, our common ratio is [tex]r=\frac{4}{5}[/tex].

We already know our initial term, [tex]a_0[/tex] is 15, so we get:

[tex]a_n=a_0(r)^{n-1}\\a_n=15(\frac{4}{5})^{n-1}[/tex]

The volume of the rectangular prism is the amount of space in the prism

The volume of the rectangular prism is x^3+8x^2+19x+12 cubic inches

The given parameters are:

Base area = x^2+5x+4

Height = x + 3

The volume is then calculated as:

Volume = Base area * Height

So, we have:

Volume = (x^2+5x+4) * (x + 3)

Expand

Volume = x^3+5x^2+4x + 3x^2+15x+12

Collect like terms

Volume = x^3+5x^2+ 3x^2+4x +15x+12

Evaluate the sum

Volume = x^3+8x^2+19x+12
