Answer:

a) Number of projects in the first year = 90

b) Earnings in the twelfth year = $116500

Total money earned in 12 years = $969000

Step-by-step explanation:

Given that:

Number of projects done in fourth year = 129

Number of projects done in tenth year = 207

There is a fixed increase every year.

a) To find:

Number of projects done in the first year.

This problem is nothing but a case of arithmetic progression.

Let the first term i.e. number of projects done in first year = [tex]a[/tex]

Given that:

[tex]a_4=129\\a_{10}=207[/tex]

Formula for [tex]n^{th}[/tex] term of an Arithmetic Progression is given as:

[tex]a_n=a+(n-1)d[/tex]

Where [tex]d[/tex] will represent the number of projects increased every year.

and [tex]n[/tex] is the year number.

[tex]a_4=129=a+(4-1)d \\\Rightarrow 129=a+3d .....(1)\\a_{10}=207=a+(10-1)d \\\Rightarrow 207=a+9d .....(2)[/tex]

Subtracting (2) from (1):

[tex]78 = 6d\\\Rightarrow d =13[/tex]

By equation (1):

[tex]129 =a+3\times 13\\\Rightarrow a =129-39\\\Rightarrow a =90[/tex]

Number of projects in the first year = 90

b)

Number of projects in the twelfth year =

[tex]a_{12} = a+11d\\\Rightarrow a_{12} = 90+11\times 13 =233[/tex]

Each project pays $500

Earnings in the twelfth year = 233 [tex]\times[/tex] 500 = $116500

Sum of an AP is given as:

[tex]S_n=\dfrac{n}{2}(2a+(n-1)d)\\\Rightarrow S_{12}=\dfrac{12}{2}(2\times 90+(12-1)\times 13)\\\Rightarrow S_{12}=6\times 323\\\Rightarrow S_{12}=1938[/tex]

It gives us the total number of projects done in 12 years = 1938

Total money earned in 12 years = 500 [tex]\times[/tex] 1938 = $969000

Answer:

y = 4x + 9, y = -3x - 5

y = 2x + 5, y = 5x + 11

and y= 3x + 7, y = -x - 1

I just did this on Plato/Edmentum xD

The system of equations that intersect at point A = (-2, 1) is:

y = 4x + 9

y = -3x - 5

y = 2x + 5

y = 5x + 11

y = 3x + 7

y = -x - 1

We have,

Let's substitute the coordinates (-2, 1) into each equation to find the correct system of equations:

y = 10x - 1

Substituting (-2, 1):

1 = 10(-2) - 1

1 = -20 - 1

1 = -21 (Not satisfied)

y = 4x + 9

Substituting (-2, 1):

1 = 4(-2) + 9

1 = -8 + 9

1 = 1 (Satisfied)

y = -3x - 5

Substituting (-2, 1):

1 = -3(-2) - 5

1 = 6 - 5

1 = 1 (Satisfied)

y = 2x + 5

Substituting (-2, 1):

1 = 2(-2) + 5

1 = -4 + 5

1 = 1 (Satisfied)

y = x - 1

Substituting (-2, 1):

1 = -2 - 1

1 = -3 (Not satisfied)

y = 5x + 11

Substituting (-2, 1):

1 = 5(-2) + 11

1 = -10 + 11

1 = 1 (Satisfied)

y = 3x + 7

Substituting (-2, 1):

1 = 3(-2) + 7

1 = -6 + 7

1 = 1 (Satisfied)

y = -x - 1

Substituting (-2, 1):

1 = -(-2) - 1

1 = 2 - 1

1 = 1 (Satisfied)

Thus,

The system of equations that intersect at point A = (-2, 1) is:

y = 4x + 9

y = -3x - 5

y = 2x + 5

y = 5x + 11

y = 3x + 7

y = -x - 1

[tex]GH = 7\ meters[/tex]

Step-by-step explanation:

Given

[tex]GH = 7\ meters[/tex]

Required

Length of GH after two rotations

In transformations, when a point, shape, line or line segment is rotated; the orientation and location of the point, shape, line or line segment change.

However, the length of the point, shape, line or line segment remains the same.

This is to say that:

After line segment GH is rotated twice, its length will remain unchanged.

Hence:

[tex]GH = 7\ meters[/tex]

The price of the coat after a 40% increase in price will be $77.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

A store pays $55 for a coat. The store marks up the price by 40%. Then the marked price is calculated as,

P = $55 x (1 + 0.40)

P = $55 x 1.40

P = $77

The price of the coat after a 40% increase in price will be $77.

Answer:

4 is c; 5 is a

Step-by-step explanation:

Given points for 4: (7, 2), (11, 5)

Given info for 5: (-2, -8); slope of  3

point-slope formula: y2 - y1 = m(x2 - x1)

Plugging in points: 5 - 2 = m(11 - 7)

Now we solve for m.

3 = m4

Final step: divide both sides by 4

Answer: m = 3/4

Second equation!

Plug into point-slope formula: y + 8 = 3(x + 2)

Distributive property of equality to eliminate parentheses

y + 8 = 3x + 6

Get y by itself by subtracting 8 to both sides

y = 3x - 2
