Step-by-step explanation:

Step 1: Define

Point (0, 9)

Point (10, 5)

Step 2: Find midpoint

Step-by-step explanation:

Hey there!

Given points are: (0,9) and (10,5)

Then;

Using midpoint formula;

[tex](x,y) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]

Put all values.

[tex](x,y) = ( \frac{0 + 10}{2} , \frac{9 + 5}{2} )[/tex]

Simplify it.

[tex](x,y) = (5,7)[/tex]

Therefore, the midpoint is (5,7)

Answer:

wat 12?

Step-by-step explanation:

Answer:

wat 12????????????????????????

Answer:

Step-by-step explanation:

It is solved for C unless you C = 5/9 * F - 32*5/9

C = 5/9F - 17.8

=================

If you mean F, then Multiply both sides by  9/5

9/5 * C = F - 32

9/5  * C + 32 = F

=====================

A quick way to do this is to multiply by 2 and add 32

F = 2*C + 30

My wife, an American, always had to do this when she heard the daily temperatures in Canada.

first multiply both sides by 9/5 to get:

9/5C= F -32

Add 32 to both sides and transpose to get:

F=9/5C + 32

these are the formulas to translate between Fahrenheit and Celsius temperatures

Fahrenheit and Celsius meet at - 40 degrees

that is - 40 Fahrenheit = - 40 Celsius    

So alternitive formulas for the conversations can be written:

F=9/5 (C+40) - 40

C=5/9 (F+40) - 40

Answer:

18 white flowers

Step-by-step explanation:

We are given ratio:

Red : White

2 : 3

If Sally used 12 red flowers, how many white flowers will she use?

Let the number of white flowers Sally uses be represented by x

This is calculated as:

2/3 = 12/x

Cross Multiply

2 × x = 3 × 12

x = 3 × 12/2

x = 18 white flowers

Therefore, if Sally used 12 red flowers, the number of white flowers will she use is 18 white flowers.

Answer:

[tex]VW = 33[/tex]

Step-by-step explanation:

See attachment for complete question

Given

[tex]VY = 4x - 1[/tex]

[tex]VW = 5x + 3[/tex]

[tex]Perimeter = 112[/tex]

Required

Determine the length of VW

Perimeter is calculated as:

[tex]Perimeter = 2 * (Width + Length)[/tex]

This gives:

[tex]Perimeter = 2 * (VW + VY)[/tex]

Substitute values for VW, VY and Perimeter

[tex]112 = 2 * (4x - 1 + 5x + 3)[/tex]

Collect Like Terms

[tex]112 = 2 * (4x + 5x -1 +3)[/tex]

[tex]112 = 2 * (9x +2)[/tex]

Divide through by 2

[tex]56 = 9x + 2[/tex]

Collect Like Terms

[tex]9x = 56 - 2[/tex]

[tex]9x = 54[/tex]

[tex]x = 54/9[/tex]

[tex]x = 6[/tex]

Substitute 6 for x in [tex]VW = 5x + 3[/tex]

[tex]VW = 5 * 6 + 3[/tex]

[tex]VW = 30 + 3[/tex]

[tex]VW = 33[/tex]

Answer:

Congruent

Step-by-step explanation:

Answer:

An=A1+(n-1)d

A1 is first term, An is nth term, n is number of term, and d is common difference

therefore

A4=35, A1= -17

A4=A1+(4-1)d

35= -17+3d

35+17=3d

52=3d

52/3=3d/3

14=d

common diffrence(d)=14

An= -17+(n-1)14

An= -17+14n-14

An= -31+14n

An= 14n-31

A14 term, means n=14

From An=A1+(n-1)d

A14= -17+(14-1)14

= -17+(13×14)

= -17+182

= 165.

Therfore, the 14th term is 165.

2. A sequence has a CR of 4/5 and its eighth term (a8) is (393216/3125). What is its general equation? Its 3rd term?

solution

common ratio(r)=4/5

eighth term(G8)=393216/3125

From Gn= G1r^(n-1)

G8 means n=8

G8=G1r^(n-1)

393216/3125=G1(4/5)^(8-1)

393216/3125=G1(4/5)^7

G1=(393216/3125)/(4/5)^7

G1=600

The first term is given by G1=600

The General equation is given by

The General equation is given by Gn= 600(4/5)^(n-1)

3rd term (G3)

G3= G1(4/5)^(3-1) where n=3,

=600(4/5)^2

=600(16/25)

=384

Therefore, the 3rd term is given by G3= 384.

Step-by-step explanation:

The distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function d(t) = 500t represents the number of miles traveled in t hours.

Plug t = 3.5 hours in the equation of the function.

d(3.5) = 500(3.5)

d(3.5) = 1,750.0 miles

Thus, the distance is 1,750.0 miles if a Boeing 737 airplane travels about 500 miles per hour option (D) is correct.

Answer:

Step-by-step explanation:

This is really a sloppy diagram. You have to know if the base of the triangle is 5 or 10.

It is 5. So the area of 1 of the triangles is 1/2 * b * h

b = 5

h = 8.7

Area = 1/2 * 8.7 * 5 = 21.75

There are 4 such triangles. The total area = 4 * 21.75 = 87 sqr in

Answer:

Fifteen is a factor of the number because both 3 and 5 are prime factors.

Step-by-step explanation:

The computation is shown below:

The cube of 2 is

= 2^3

= 8

The square of 3 is

= 3^2

= 9

Now if we multiplied the 3 digits that it would be

= 8 × 9 × 5

= 360

As we know that the 15 is a factor of 360

Therefore the first option is correct

i.e.

Fifteen is a factor of the number because both 3 and 5 are prime factors.

x2 = 1

x1 = -9

y1 = 2

then plug everything into the equation

Given:

The set of points.

To find:

Which set of points represents a function?

Solution:

A set of points represents a function if there exist a unique y-value for each x-value.

It option A, the set of points is

{(1,-2), (3,-5), (3,-2), (5,-7), (7, -8)}

This is not a function because there exist two y-values y=-5 and y=-2 for x=3.

It option B, the set of points is

{(0,1),(1,−3),(2,−5),(3,−7),(4,−9)}

This is a function because there exist a unique y-value for each x-value.

It option C, the set of points is

{(−1,1),(−1,3),(−1,5),(−1,7),(−1,9)}

This is not a function because there exist five y-values y=1,3,5,7,9 for x=-1.

It option D, the set of points is

{(−4,0),(−3,−1),(−3,1),(0,−2),(0,2)}

This is not a function because there exist two y-values y=-1 and y=1 for x=-3.

Therefore, the correct option is B.
