Answer:

The average rate of change is 7.

Step-by-step explanation:

We are given the function:

[tex]f(x)=2x^2+x+5[/tex]

Which represents the number of jars of pickles, y (in tens of jars), Denise expects to sell x weeks after launching her store.

We want to find the average rate of change over 1 ≤ x ≤ 2.

Essentially, we want to find the slope over f(1) and f(2).

Thus, first evaluate the two endpoints:

[tex]f(1)=2(1)^2+(1)+5=2+1+5=8[/tex]

And:

[tex]f(2)=2(2)^2+2+5=8+2+5=15[/tex]

This gives us the two points (1, 8) and (2, 15).

Then the average rate of change will be the slope between the two:

[tex]\displaystyle m=\frac{15-8}{2-1}=7[/tex]

With units, this means that over the first and second week, Denise sold on average 70 jars of pickles per week.

Answer:

Roses = x = 4

Carnations = y = 12

Daisies = z = 8

Step-by-step explanation:

The bouquet was made up of roses, carnations, and daisies.

Let us represent:

Roses = x

Carnations = y

Daisies = z

Melanie gave her mother a bouquet of 24 flowers.

Hence,

x + y + z = 24...... Equation 1

There were twice as many daisies as roses.

z = 2x

There were three times as many carnations as roses.

y = 3x

Therefore, we substitute 2x and 3x for z and y respectively in Equation 1

x + y + z = 24...... Equation 1

x + 3x + 2x = 24

6x = 24

x = 24/6

x = 4 roses

Solving for y

y = 3x

y = 3 × 4

y = 12 Carnations

Solving for z

z = 2x

z = 2 × 4

z = 8 Daisies

How many of each kind of flower was in the bouquet?

Therefore,

Roses = x = 4

Carnations = y = 12

Daisies = z = 8

Melanie gave her mother a bouquet of 24 flowers which has three kinds of flowers

The number of roses in the bouquet  = 4

The number of carnations in the bouquet  = 12

The number of daises in the bouquet  = 8

Melanie gave her mother a bouquet of 24 flowers.

The  bouquet was made up of roses, carnations, and daisies.

Let there be x roses

Let there be y carnations

Let there be z daises in the bouquet

So the total number of flowers  in the bouquet is given by equation (1)

[tex]\rm x +y + z = 24........(1)[/tex]

There were twice as many daisies as roses.

So

[tex]\rm z =2x ....(2)[/tex]

Also , There were three times as many carnations as roses

[tex]\rm y = 3x ........(3)[/tex]

From equations (1) , (2) (3) we get

[tex]\rm z \; and \; y \; from \; (2)\; and \; (3)\; in\; (1) \; we\; get \\x + 2x +3x = 24\\6x = 24\\x= 24/6\\x = 4[/tex]

So

The number of roses in the bouquet  = 4

The number of carnations in the bouquet  = 12

The number of daises in the bouquet  = 8

Kepler-452b has a probable mass five times that of Earth, and its surface gravity is nearly twice as Earth's, though calculations of mass for exoplanets are only rough estimates. If it is a terrestrial planet, it is most likely a super-Earth with many active volcanoes due to its higher mass and density.Step-by-step explanation:

If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and  If they are each rotated 270° about the origin, they will remain parallel are true statements.

Coordinate geometry (or analytic geometry) is defined as the study of geometry using the coordinate points.

Parallel lines are coplanar infinite straight lines that do not intersect at any point.

Among the given statements the following are true.

If they are each rotated 180° about the origin, they will not remain parallel.

If they are each translated 7 units to the left, they will remain parallel.

If they are each rotated 270° about the origin, they will remain parallel.

Hence, If they are each rotated 180° about the origin, they will not remain parallel, If they are each translated 7 units to the left, they will remain parallel and  If they are each rotated 270° about the origin, they will remain parallel are true statements.

Answer:B=7a

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

5a = 540            [ all interior angles r equal to 540 as "(n-2)x 180  (Interior                                           ____________________________________________angle poperty )]

a= 540/5 = 108   (one interior angle)

x + a = 180                      (linear pair)

x= 180 - a

x = 180 - 108 = 72

One exterior angle = x = 360 / 5 = 72        ( 360 by the number of sides )

Answer:

  x = 3.6

Step-by-step explanation:

It can be helpful to write down corresponding sides and their measures.

  AB = 5, PQ = 6

  BC = 3, QR = x

  CD = 2, RS = 2.4

  DA = 4, SP = 4.8

Then you can look for easy ways to find x. You can tell from this table that all of the values in PQRS are 6/5 = 1.2 times the corresponding values in ABCD.

Then ...

  QR = 1.2×BC = 1.2×3

  QR = x = 3.6

_____

Other ways you can figure x are ...

  x/BC = PQ/AB

  x = (BC)(PQ/AB) = 3(6/5) = 3.6 . . . . the method we used

__

  x/RS = BC/CD

  x = 2.4(3/2) = 3.6

__

  x/SP = BC/DA

  x = 4.8(3/4) = 3.6

Angle O=64

Side n=16.68902(round if needed)

We are given

Angle M which equal 26.

Angle N equals 90 degrees

Side MN which equal 15.

We are asked to find all the missing elements of the triangle.

[tex]90 + 26 + x = 180[/tex]

[tex]116 + x = 180[/tex]

[tex]x = 64[/tex]

Angle O=64 degrees

We can find side m by doing law of sines.

[tex] \frac{on}{ \sin(26) } = \frac{mn}{ \sin(64) } [/tex]

[tex] \frac{on}{ \sin(26) } = \frac{15}{ \sin(64) } [/tex]

[tex]on = \frac{15}{ \sin(64) } \times \sin(26) [/tex]

which is 7.315(round if neeeded).

We can find side n using pythagorean theorem,

[tex] {15}^{2} + {7.3}^{2} = {n}^{2} [/tex]

[tex]225 + 53.29 = {n}^{2} [/tex]

[tex] \sqrt{278.29} [/tex]

Answer: 84.1m

Step-by-step explanation:

Let the height of the flagpole be represented by x.

First and foremost, we have to know that the cosine of 18° = 0.9511.

The equation to get the height will then be:

0.9511 = 80/x

Cross multiply

(0.9511 × x) = 80

0.9511x = 80

Divide both side by 0.9511

0.9511x/0.9511 = 80/0.9511

x = 84.1

The height of the flagpole is 84.1m

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the data given in the question,

The total amount Kiran is having in the bank = $100

He needs to have at least $25 in the account at the end of the year.

So, the money he can spend in a year = $100 - $25 = $75

1 year = 12 months

So, the amount of money spent per month will be,

75/12 = $6.25
