Seven times the quotient of x and 9 added to 2
gives
25. What is x?

A' will be (-3,9)  B' will be (4,6) and C' will be (-5,-1). t are the coordinates of the vertices of aa'b'c' for the reflection rg.

A pair of numbers that specify where a point is situated on a coordinate plane using the horizontal and vertical separations from the two reference axes. usually represented by a pair of x-values and y-values (x,y).

In this problem, basically you have three points and 6 straight lines(4 described in the problem and x and y axis) in a 2-D plane. You have to find the reflection of these three points with respect to these 6 lines one by one.

Points are:

A(9,-3)

B(6,4)

C(-1,-5)

Case 1:

Line is X-axis  i.e.  y  =  0.

If you take reflection about x-axis then you can observe that the x - co-ordinate will remain same while y-co-ordinate will change its sign.

So A' will be (9,3), B' will be (6,-4) and C' will be (-1,5)

Case 2:

Line is y-axis  i.e.  x = 0

Here the analogy will remain same except here the y - co-ordinate will remain same and x - co-ordinate will change ite sign.

So, A' will be (-9,-3)  B' will be (-6,4) and C' will be (1,-5).

Case 3:

Reflection about line "m"  i.e.  x = -5

This is a vertical line. Suppose the point whose reflection is to be found about is line is at a perpendicular distance of "k" from the line on right side, then its reflection will be "k" distance on the left from this line on the same horizontal line. So y-co-ordinate will not change.

For A(9,-3), it is at a distance of 14 units from the line on the right side so its reflection will be 14 units on the left with same y - co-ordinate. So its x - co-ordinate will be -5-14  =  -19

So A' will be (-19,-3)

Similarly for B,  B' will be (-16,4) and C' will be (-9,-5).

This graph will help you understand better.

The red line is x  =  -5.

The case for line y = 1 and y = -2 will be similar.

Case 5:

Reflection about the line y  =  x

photos are attached .............

So, A' will be (-3,9)  B' will be (4,6) and C' will be (-5,-1).

We can use these two observations to find the reflection of any point about any line:

(i) The midpoint of the given point and the reflection point will lie on the given line about which the reflection is to be found.

(ii) The product of slope of given line and the line joining the given point and the reflection point is -1.

The measures of the interior and exterior angles ∠1, ∠2, ∠3, ∠4, ∠5, ∠7, ∠8, and ∠9 are 90°, 90°, 90°, 122°, 58°, 58°, 148°, 32°, and 148°, respectively.

We are given a triangle. One of the angles is 122 degrees, as shown in the diagram. We need to find all the interior and exterior angles. The vertically opposite angles are equal. The angle ∠4 is vertically opposite to the given angle. So, ∠4 = 122°. The angle ∠5 and the given angle form a linear pair. So, the angle ∠5 = 180° - 122° = 58°. The angle ∠6 is vertically opposite to the angle ∠5. So, the angle ∠6 = 58°. The angles ∠1, ∠2, and ∠3 are angles made by coordinate axes that are perpendicular to each other. So, the angles ∠1 = ∠2 = ∠3 = 90°. Now we use the angle sum property of a triangle. The sum of all the interior angles of a triangle is 180°. So, we can write the equation : ∠6 + ∠1 + ∠8 = 180°. So, ∠8 = 180° - (∠6 + ∠1) = 180° - (58° + 90°) = 180° - 148° = 32°. The angles ∠8 and ∠9 form a linear pair. So, ∠9 = 180 - 32° = 148°. The angle ∠7 is vertically opposite to the angle ∠9. So, the angle ∠7 = 148°.

The perimeter of the given rectangle is 16r-14s centimeters.

Let width be represented by=w

Let length be represented by=l

Let perimeter be represented by=p

Then,

l=(r-5s)centimeters (Given in the question)

while w=(7r-2s)centimeters (Given in the question)

The formula for the perimeter of a rectangle= 2(l+b)

where l is the length while b is the breadth of the rectangle.

On putting values in the equation:

p=2(l+b)

p=2(l+w)

p=2[(7r-2s)+(r-5s)]

on opening the bracket 2 is multiplied by both terms.

p=2(7r-2s)+2(r-5s)

p=(2x7r-2x2s)+(2xr-2x5s)

p=(14r-4s)+(2r-10s)

p=14r-4s+2r-10s

p=14r+2r-4s-10s

p=14r+2r-(4s+10s)

p=14r+2r-(14s)

p=16r-(14s)

Thus,

p=16r-14s centimeters

The perimeter of the given rectangle is 16r-14s centimeters.

The measure of the angle ∠ABD is calculated as 138° from the given data and figure.

The total of a triangle's three internal angles is 180 degrees, according to the angle sum property. When the values of the other two angles are known, the angle sum property is utilized to compute the measure of an unknown interior angle.

SAS stands for Side-Angle-Side Similarity. If the proportion of the two sides of one triangle is the same as the proportion of the two sides of another triangle, and the angle inscribed by the two sides of both triangles is equal, two triangles are said to be similar. 

Given: ΔACD and ΔBCD are isosceles.

          AD ≅ AC

          BD ≅ BC

         ∠BAC = 18°

         ∠BDC = 48°

We need to determine the measure of  ∠ABD.

Since,   AD ≅ AC

∠DAB = ∠BAC = 18°

Since, BD ≅ BC

∠BDC = ∠BCD = 48°

By triangle's angle sum property,

∠BDC + ∠BCD + ∠DBC = 180°

48° + 48° + ∠DBC = 180°

∠DBC = 84°

Also, ∠ABD = ∠ABC  [By SAS rule of ΔABD + ΔABC]

From the figure we can see that,

∠DBC + ∠ABD + ∠ABC = 360°

84° + 2∠ABD = 360°  [∵ ∠ABD = ∠ABC]

2∠ABD = 276

∠ABD = 138°

Therefore, the measure of the angle ∠ABD is calculated as 138° from the given data and figure.

In this exercise we have to use the knowledge of depth to be able to calculate the depth that is being seen by the telescope, in this way we can say that:

45 feet deep

First, knowing that the formula for the parabola is:

4py=x²

Now P is the distance from the vertex to the focus or to the directrix which is equal to 20, we can say that:

4(20)y=x²

80y=x²

80y=x²

80y=60²

80y=3600

y=45

Answer:

75ft

Step-by-step explanation:

We can let the parabola open upward......so we will  have the form

4a ( y - k)  =  (x - h)^2

The distance from the vertex to the focus =  20   = a

We can let the vertex be   ( 80, 30)

So we have the form

4(20) ( y- 30)  = (x - 80)^2   simplify

80 ( y - 30)  = ( x - 80)^2

Since the diameter  is 120 ft...the radius is 60 ft.....so we can let one point on the parabola be   ( 80 + 60 , a) =

(140 , a)......where a  is the height of the dish....so we have that

80 ( a - 30) = (140 - 80)^2

80 ( a - 30)  = (60)^2

80 ( a - 30) = 3600      divide both sides by  80

a -  30 =  45      add 30 to both sides

a = 75 ft  = the height of the dish

To make this chart, I used the heigths:

• Mercedario: 6770m

• Misti, Volcán: 5820m

• Pular: 6230m

• Sajama: 6520m

• Talima: 5220m

Look at the chart below:

a) Remember that the coordinates for any given point in the cartesian system have two components, one in the X axis and the secon one in the Y axis. (X,Y)

The coordinates for P and Q are:

P (b,a)

Q(d,e)

b) If you have the formula for the function, you'll se that to determine the value on the Y axis for a given value of X you have to replace that value in the formula. This means that Y= f(x).

In this example the value of Y for X=b is equal to a, so f(b)= a

c) For f(x)=e, you have to identify the value of x that croses to Y=e, in this grapfic that value is d

d) f(z)=c and f(x)=z

If you watch the graphic, c is in the y-axis, this means that the x value of its coordinate is zero. So z=0

Now for f(x)=z, this means that you have to find the value of x when the value of Y is zero. To determine this value you have to see where the function crosses the X-axis.

The function crosses the X-axis in point h, so when f(x)= z, x=h

e) If f(b)=-f(d) this means that both |b| and |d| are equal, you can express it as:

b=-d

The radius of the circular field with area 14400 square feet is 67.7ft

A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.

The radius of a circular field with an area of 14400 square feet can be calculated by the formula:

Area of a circle(A) = [tex]\pi r^{2}[/tex]

where A = 14400[tex]ft^{2}[/tex]

[tex]\pi[/tex] = constant which is 3.142

A = [tex]\pi[/tex][tex]r^{2}[/tex], where A = area of circle , r = radius

divide both sides by c

A/[tex]\pi[/tex] = [tex]r^{2}[/tex]

[tex]r^{2}[/tex] = A/[tex]\pi[/tex]

r = [tex]\sqrt{\frac{A}{\pi } }[/tex]

Substitute the values of A and [tex]\pi[/tex]

r = [tex]\sqrt{\frac{14400}{3.142} }[/tex]
