Find the equation of the line perpendicular to -9x+4y=8 that contains the point (9,7)

Answers

Answer:

[tex]\[y=-\frac{4}{9}x+11\][/tex]

Step-by-step explanation:

Equation of the given line is [tex]\[-9x+4y=8\][/tex]

Slope of the line = [tex]\[\frac{9}{4}\][/tex]

Slope of the perpendicular line  = [tex]\[-\frac{4}{9}\][/tex]

Equation of the line perpendicular to the given line is [tex]\[y=mx+c\][/tex]

[tex]\[y=-\frac{4}{9}x+c\][/tex]

But this line passes through (9,7)

Substituting the values in the equation:

[tex]\[7=-4+c\][/tex]

=> [tex]\[c=7+4=11\][/tex]

So the overall equation of the parallel line is given by [tex]\[y=-\frac{4}{9}x+11\][/tex]

The trigonometric form of a complex number is unique - True or false?

Answers

Answer with explanation:

let, Z= a + i b,be a complex number.

Where, a = r cos A

 b= r sin A

[tex]a^2 + b^2=(r cos A)^2 +(r sin A)^2\\\\ a^2 + b^2=r^2(cos^2 A+sin^2 A)\\\\ a^2 + b^2=r^2\\\\r=\sqrt{a^2 + b^2}[/tex]

[tex]Z=r cos A + i r sin A\\\\Z=r(cos A + i sin A)\\\\ Z=re^{iA},\text{Where}, e^{i\alpha }=cos \alpha +i sin\alpha[/tex]

Now, if we replace A, by, 2 kπ + A,in the above equation,where k is any positive integer,beginning from ,0.k=0,1,2,3,4,....

Where do the following graphs intersect? Show how you can find the intersection point algebraically.

1) y-2x=3
2) y-3= x^2

Answers

Solve equation (1) for y
y-2x = 3
y-2x+2x = 3+2x
y = 2x+3

Plug that into equation (2)
y - 3 = x^2
2x+3 - 3 = x^2
2x = x^2

Get everything to one side
2x = x^2
2x-2x = x^2-2x
0 = x^2-2x
x^2-2x = 0

Now factor and use the zero product property to find the solutions for x
x^2-2x = 0
x(x-2) = 0
x = 0 or x-2 = 0
x = 0 or x = 2

If x = 0, then y is...
y = 2x+3
y = 2(0)+3
y = 3
So (x,y) = (0,3) is one solution of the system. This is one point where the graphs intersect.

If x = 2, then y is...
y = 2x+3
y = 2(2)+3
y = 4+3
y = 7
So (x,y) = (2,7) is another solution to the system. This is another point where the graphs intersect.

See the attached image for a visual. The two curves cross at point A and point B
A = (0,3)
B = (2,7)

A parabola has a focus of F(2, -0.5) and a directrix of y=-1.5 P(x,y) represents any point on the parabola, while D(x, -1.5) represents any point on the directrix.

What are the steps required to find the equation of the parabola?

Answers

The sketch of the parabola is attached below

We have the focus [tex](a,b) = (2, -0.5)[/tex]
The point [tex]P(x,y)[/tex]
The directrix, c at [tex]y=-1.5[/tex]

The steps to find the equation of the parabola are as follows

Step 1
Find the distance between the focus and the point P using Pythagoras. We have two coordinates; [tex](2, -0.5)[/tex] and [tex](x,y)[/tex].
We need the vertical and horizontal distances to find the hypotenuse (the diagram is shown in the second diagram).
The distance between the focus and point P is given by
[tex] \sqrt{ (x-a)^{2}+ (y-b)^{2} } [/tex]

Step 2
Find the distance between the point P to the directrix [tex]c[/tex]. It is a vertical distance between y and c, expressed as [tex]y-c[/tex]

Step 3
The equation of parabola is then given as 
[tex] \sqrt{ (x-a)^{2}+ (y-b)^{2} } [/tex]=[tex]y-c[/tex]
[tex] (x-a)^{2}+ (y-b)^{2}= (y-c)^{2} [/tex] ⇒ substituting a, b and c
[tex] (x-2)^{2}+ (y--0.5)^{2} = (y--1.5)^{2} [/tex]
[tex] (x-2)^{2}+ (y+0.5)^{2}= (y+1.5)^{2} [/tex]⇒Rearranging and making [tex]y[/tex] the subject gives

3. How many different "words" can be made from the given word by re-arranging the letters?

a) VECTOR

B) TRUST

Answers

1. 

Assume the people A, B, C, D and E are sitting in a row.

since there are 5 positions, they can sit in 5*4*3*2*1=120 ways.

consider 1 certain sitting position, for example ABCDE, that is B has A to his right, C to his left. D has C to his right and E to his left. And so on.

the positions 

ABCDE
BCDEA
CDEAB
DEABC
EABCD

while in a row are different positions, in a round table they are the same thing.

(read the letters starting from A, and when the letters finish, continue reading from the beginning of the row. They all read "ABCDE")

This means that any arrangement in a round table, is converted to 5 arrangements in a row.

So there are in total  [tex] \frac{5!}{5}=4*3*2*1=24 [/tex] arrangements of 5 people around a table.

2. check picture.

Consider the case where A is at (2, 2) and B is at (5, 6)

A can move to B through 3 horizontal units to the right, we call them E (for East) and 4 vertical units up, which we call N (for north).

the total path is 7 units.

it can be done in several ways, for example:

ENNNENE (the red path shown in the figure)
NNEEENN (the black path shown in the figure)

In total there are 
[tex] \frac{7!}{3!*4!}= \frac{7*6*5*4!}{3!*4!}= \frac{7*6*5}{3!}= 35 [/tex] paths.

Remark: 7! is the number of arrangements if the letters were different. We divide by 3! because of the 3 E's and 4! because of the 4 N's. 

Another possibility could be A'(3, -5), B'(8,-3).

From A' to B' we go by a total of 5 E and 2 N, so there are 

[tex] \frac{7!}{2!*5!}= \frac{7*6*5!}{2!*5!}= \frac{7*6}{2}= 42 [/tex] paths in total.
there is one more possibility
[tex] \frac{7!}{1!(6!)}=7 [/tex]

C.

a) consider the letters {V,E,C,T,O,R}

we can form 6*5*4*3*2*1=720 words, as the first digit can be any of the 6 letters, combined with 5 for the second letter and so on.

b) the difference with a is that we have 5 letters and we have 2 T.

we have in total 5*4*3*2*1=120 arrangements of these letters, if the 2 T's were considered as separate.

consider the arrangements:

[tex]T_1RUST_2[/tex] and [tex]T_2RUST_1[/tex].

We read bth as just TRUST, but the permutation formula 5*4*3*2*1 considers these as 2 different.

this is why we need to divide 120 by 2, to get the actual number of words that can be formed. So the number is 60.

Raquel and Van live in two different cities. As part of a project, they each record the lowest prices for a gallon of gas at gas stations around their cities on the same day. Raquel’s data reflect a mean price of $3.42 with a standard deviation of 0.07. Van’s data reflect a mean price of $3.78 with a standard deviation of 0.23. Which statement is true about their gas-price data? Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78. Van’s data are most likely closer to $3.42 than Raquel’s data are to $3.78. Raquel’s data are most likely closer to $3.78 than Van’s data are to $3.42. Van’s data are most likely closer to $3.78 than Raquel’s data are to $3.42.

Answers

the standard deviation shows the dispersion (how close) of the data. Therefore the correct statement is A:
- Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

Answer:

Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

Step-by-step explanation:

We know that a standard deviation is a measure that is used to find the amount of dispersion or variation of the data set.If standard deviation is low this means that the data points tends close to the mean of the data set.while a higher standard deviation means that the data values are spread to a greater range.

Hence, form the given information we may imply that:

Raquel’s data are most likely closer to $3.42 than Van’s data are to $3.78.

( Since, the standard deviation of Raquel's data is low which is 0.07 as compared to Van's data ( which is 0.23).

Hence, the Raquel's data will tend close to the mean which is $ 3.42. )

The height of the tree maintaining the given ratio is 23.54 feet.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

Don height = 6 feet

His shadow = 13 feet

The ratio of height to shadow = 6/13

Tree height = x (let's say)

There will be only on solution if either of these conditions is met:

the given angle is opposite the longest sidethe triangle is a right triangle (the ratio of the side opposite the angle to the other given side is equal to the sine of the angle)

Step-by-step explanation:

Consider the SSA geometry with the angle placed in standard position at the origin and its adjacent given side (the second side of SSA) extending along the +x axis. Draw a circle having a radius equal to the length of the first side of SSA, centered on the vertex between the two segments on the +x axis.

There are three possibilities for the way this circle intersects the other ray of the angle (the ray that is not the x-axis):

the first side is as long or longer than the second side, so there is one point of intersection (one solution to the triangle, purple in the attachment)the first side is just long enough to be tangent to the other ray, so there is one point of intersection (one solution to the triangle, green in the attachment)the first side is between these lengths, so intersects the other ray in two places, giving two solutions to the triangle, red in the attachment.

A point on an ellipse is 11 units from one focus and 7 units from the other. What is the length of the major axis?

P is a point on the ellipse
A and B are the foci (or focus)

The length of major axis is given by either VA+AW or AP+BP
One useful fact to know that AP+BP is constant wherever the point P is on the ellipse

We know that the distance of the point 'P' from one focus is 11 units and from the other focus is 7 units, so we know the length of AP and BP.

Hence, the length of major axis is 11+7=18 units

Answers

Projectile motion is characterized by a motion that has two vector forces: the velocity along the x and y directions. As a result, the motion follows an arc-shaped direction. These two directions are actually independent of each other. 

There are already derived equations for this so it is already convenient. However, your given equation for range is incomplete. The correct equation is:

R = v₀²sin2θ/g

where
R = 140 ft
v₀ = 120 ft/s
g = 32.2 m/s²

Substituting the values,

sin 2θ = Rg/v₀²
sin 2θ = (140)(32.2)/(120²)
sin 2θ = 0.313
2θ = sin ⁻¹ (0.313)

Conjecture for interior angles of complex polygons

Answers

The best way to do this is to draw out a few polygons and divide them into triangles, then add up the angles. If you start with a square, then a pentagon, then a hexagon, then a heptagon, by the time you get to an octagon, you will see a pattern and can make your inference. Remember that to make an inference is to come to a conclusion based on your observation. So grab a piece of paper and a pencil and start drawing!! You will probably find that they actually did you for this in the Geometry textbook:)

Final answer:

The conjecture for interior angles of complex polygons involves using the formula (n-2)×180 degrees for regular polygons and more complex considerations for 3D shapes like pentagonal bipyramids or square antiprisms. As the number of sides increases, calculations become more intricate and the interior angles can approach 180 degrees in very large polygons.

Explanation:

The question involves making a conjecture for the interior angles of complex polygons. A commonly used theorem related to this is that the sum of the interior angles of a polygon can be found using the formula (n-2)×180 degrees, where n is the number of sides in the polygon. For instance, to find the sum of the interior angles of a pentagon (a polygon with five sides), we calculate (5-2)×180 degrees = 540 degrees. As the number of sides increases, our calculations can become more complex, especially when dealing with non-regular polygons (where the sides and angles don't all have the same length/measure).

When considering the interior angles of complex geometries like a pentagonal bipyramid or a square antiprism, it's essential to recognize that their interior angles may involve multiple planes and hence cannot be calculated using the simple 2D polygon interior angle sum formula. These shapes involve three-dimensional calculations and often require advanced geometry or trigonometry to dissect into understandable components.

Considering large numbers of sides and complex figures, the interior angle measures can approach different limits. For example, as the number of sides I becomes very large, the interior angle measures can become very close to 180 degrees, which is suggested by the idea that for a polygon with infinitely many sides (approaching a circle), each interior angle would be 180 degrees.

A rectangular flower garden has area 32 square feet. if the width of the garden is 4 feet less than the length, what is the perimeter, in feet, of the garden?

Answers

To determine the perimeter of the rectangular flower garden, we need to know the measurement of the sides of the rectangle so we have to know the length and the width. The given measurements are the area, and the relation of the width and the length. From these, we generate equations to calculate the width and the length. We do as follows:

Area = Length x Width

where length = x ft
           width = x - 4 ft
           area = 32 ft^2

32 = x (x -4)
32 = x^2 - 4x

Solving for the positive value of x, 

x = 8 ft = length
width = x -4 = 8 - 4 = 4 ft

Perimeter = 2(length) + 2(width) = 2(8) + 2(4) = 24 ft

The perimeter of the garden is 24 feet.

(06.06) Which of the following demonstrates the Commutative Property of Multiplication? 3(4a − 2) = 12a − 6 3(4a − 2) = (4a − 2) ⋅ 3 12a − 6 = (4a − 2) ⋅ 3 (3 ⋅ 4a) − 2 = 3(4a − 2)

Answers

commutative property of multiplication states : a * b = b * a...so basically, u can move the numbers around and it will still equal the same thing
3(4a - 2) = (4a - 2) * 3 <==
Commutative means you can reverse the order  without affecting the result of the multiplication:-   a*b = b*a.
so its the second option:-

3(4a - 2) = (4a - 2).3
