Answer:

at 0  the amount is 5

1 is 7.5

2 is 10

3 is 12.5

the initial value is the y intercept when the value ox x=0

the initial value is 5

the rate of change is the total change of a function of the out put (y) divided by the change of the input (x)

f(x2)-f(x1)/x2-x1

10-7.5/2-1

2.5/1=2.5

or m=y2-y1/x2/x1=10-7.5/2-1=2.5

y=2.5x+5

Answer:

12.56 [tex]cm^2[/tex] is the error in area of circle.

Step-by-step explanation:

Given that:

Radius of the circle, r = 10 cm

Error in measurement of radius, [tex]\triangle r[/tex] = 0.2 cm

To find:

The error in area of circle = ?

Solution:

First of all, let us have a look at the percentage error in measurement of radius:

[tex]\dfrac{\triangle r}{r}\times 100 = \dfrac{0.2}{10}\times 100 = 2\%[/tex]

Now, we know that Area of a circle is given as:

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

[tex]\Rightarrow \dfrac{\triangle A}{A} \times 100 = 2 \times \dfrac{\triangle r}{r} \times 100\\\Rightarrow \dfrac{\triangle A}{A} = 4\%[/tex]

Area according to r = 10

[tex]A = 3.14\times 10^2 = 314 cm^2[/tex]

Now, error in area = 4% of 314 [tex]cm^2[/tex]

[tex]\Rightarrow \dfrac{4}{100} \times 314 = 12.56 cm^2[/tex]

So, the answer is:

12.56 [tex]cm^2[/tex] is the error in area of circle.

Answer:

x = 7 . y = 13/3

Step-by-step explanation:

Solve the following system:

{y = x/3 + 2

y = (4 x)/3 - 5

Express the system in standard form:

{-x/3 + y = 2

-(4 x)/3 + y = -5

Express the system in matrix form:

(-1/3 | 1

-4/3 | 1)(x

y) = (2

-5)

Write the system in augmented matrix form and use Gaussian elimination:

(-1/3 | 1 | 2

-4/3 | 1 | -5)

Swap row 1 with row 2:

(-4/3 | 1 | -5

-1/3 | 1 | 2)

Subtract 1/4 × (row 1) from row 2:

(-4/3 | 1 | -5

0 | 3/4 | 13/4)

Multiply row 1 by 3:

(-4 | 3 | -15

0 | 3/4 | 13/4)

Multiply row 2 by 4:

(-4 | 3 | -15

0 | 3 | 13)

Divide row 2 by 3:

(-4 | 3 | -15

0 | 1 | 13/3)

Subtract 3 × (row 2) from row 1:

(-4 | 0 | -28

0 | 1 | 13/3)

Divide row 1 by -4:

(1 | 0 | 7

0 | 1 | 13/3)

Answer:

Please refer to the attached image for the graph of g(x).

Step-by-step explanation:

First of all, let us find the value of g(x).

Given that:

[tex]f(x) =2x-5[/tex] and

[tex]g(x) = f(x+1)[/tex]

To find: The graph of g(x) = ?

Solution:

[tex]f(x+1)[/tex] means we replace  'x' with 'x+1' and we get g(x).

Let us replace x with x+1 in f(x):

[tex]f(x+1) = 2(x+1)-5\\\Rightarrow f(x+1) = 2x+2-5\\\Rightarrow f(x+1) = 2x-3\\\therefore g(x) = 2x-3[/tex]

Now let [tex]y=g(x) =2x-3[/tex]

Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g(x).

Putting x = 0,

[tex]y=2\times0-3\\\Rightarrow y =-3[/tex]

So, one point is A(0,-3)

Now, let us put y = 0 and find out x.

[tex]0=2x-3\\\Rightarrow x=\dfrac{3}{2}[/tex]

So, second point is [tex]B(\frac{3}{2},0)[/tex].

Now, let us plot A and B then extend the line joining AB.

Please refer to the attached image for the graph of function:

g(x) = 2x - 3

Answer:

5 <x

Step-by-step explanation:

–2(3x + 2) > –8x + 6

Divide each side by -2, remembering to flip the inequality

–2/-2(3x + 2) < –8x/-2 + 6/-2

3x+2 < 4x-3

Subtract 3x from each side

3x-3x+2 < 4x-3x-3

2 < x-3

Add 3 to each side

2+3 < x-3+3

5 <x

Answer:

Step-by-step explanation:

-2( 3x + 2) > -8x + 6

-2*3x + (-2)*2 > -8x + 6

-6x  - 4 > -8x + 6

Add 4 to both sides

-6x - 4 + 4 > -8x + 6 + 4   { add like terms}

-6x > -8x + 10

Add 8x to both sides

-6x + 8x > - 8x + 10 + 8x

2x  > 10

Divide both sides by 2

2x/2 > 10/2

x > 5

Answer:

A-does not exist  

Step-by-step explanation:

The pythagorian theorem :

That's absurd . A side cannot be negative since it's a distance

It was obvious from the beginning since one of the sides is greater than the hypotenus wich is impossible x≥x-2

Answer:

A. does not exist

Step-by-step explanation:

Since this is a right triangle we can find the value of x using Phytagorian Theorem

(x-2)^2 = 12^2 + x^2

x^2 -4x + 4 = 144 + x^2 (x^2 will be eliminated)

-4x = 144

x = -36 since the side lengths cannot be negative we select the option A which says it doesn't exist.

Answer:

Option C.

Step-by-step explanation:

So, in the question above we are given that the value or parameters for the required initial contribution (RIC) and

the minimum subsequent investment (MSI) for each options and we are going to calculate the amount that will be gotten after investing in each options and the one that gives the highest values will be the correct option, which in this case is OPTION C.

So, we will be starting from the OPTION C, in white have that the

required initial contribution (RIC) = $5,000 and the minimum subsequent investment (MSI) = $100 for option C.

One year = 12 months

10 years = x months.

x = 10 × 12 = 120 months in ten years.

Thus, the formula for the Calculation is given below;

= 120 months × minimum subsequent investment (MSI) + required initial contribution (RIC).

= (120 months × $100) + $5,000 = $17,000.

If we Calculate for the other options with this format, we will have values for option A = $13, 000 and option B= $2,900 and the value for the investment in option D = $12,050.

$17,000 is the highest which is for option option C. Therefore, Sean should put his money in option c for better investment.

Answer:

(4, 4 )

Step-by-step explanation:

Given the 2 equations

y = x² - 6x + 12 → (1)

y = 2x - 4 → (2)

Substitute y = x² - 6x + 12 into (2)

x² - 6x + 12 = 2x - 4 ( subtract 2x - 4 from both sides )

x² - 8x + 16 = 0 ← in standard form

(x - 4)² = 0 ← in factored form

x - 4 = 0 ⇒ x = 4

Substitute x = 4 into (2) for corresponding value of y

y = 2(4) - 4 = 8 - 4 = 4

Solution is (4, 4 )

Answer: (n + 5)(n - 5)

Explanation: In this problem, we have a binomial that's the difference of two squares because n² and 25 are both perfect squares and we are subtracting or taking the difference of these two squares.

Since the difference of two squares factors as the product of two binomials, we can setup our parenthses and in the first position, we use the factors of n² that are the same which are n · n.

In the second position, we use +5 and -5 as our factors of -25.

So our answer is (n + 5)(n - 5).

Answer:

The first one.

Step-by-step explanation:

A linear function is a straight line, regardless of direction.

The first graph is of a linear function.

The phrase linear function denotes to function which is linear, specifically of this form:

[tex]f(x) = mx + c[/tex]

This is also written as:

[tex]y = mx + c[/tex]

It is written so that we can take the outputs of the function f(x) in a separate variable for further mathematical treatments with ease.

Now when that second equation is plotted on XY plane, you get a straight line graph since this is the equation form of any straight line, in geometry.

All the straight lines are covered under y = mx + c linear function form.

Since the first graph contains a plot of straight line, thus the first graph is of linear function.

The second graph is of downwardly opened vertical parabola which is of degree 2, thus not linear.

Thus first graph is the graph of a linear function.

Answer:

27.2

Step-by-step explanation:

The mean age of 8 women in the office is 20 years old

The mean age of 12 men in an office is 32 years old

The first step is to calculate the mean of the both the men and women in the office, that way we will be able to know the sum.

The mean of the women can be calculated by taking the sum of the value and dividing by the number

= 20+20+20+20+20+20+20+20/8

= 160/8

= 20

The mean of the men can be calculated by taking the sum of the values and dividing by the number

=32+32+32+32+32+32+32+32+32+32+32+32/12

= 384/12

= 32

Therefore, to find the mean age of people in the office we add the sum of both the men and women and divide by the total number of people in the office

= 384+160/20

= 544/20

= 27.2

Hence the mean age of people in the office is 27.2

1 revolution = 360 degrees

360 degrees x 90 revolutions per minute = 32,400 degrees per minute.

1 minute = 60 seconds.

32,400 degrees per minute / 60 seconds = 540 degrees per second.

Answer:

8 boards.

Step-by-step explanation:

Since he bought a few of each length. The only combination that works is when he bought 5 of the 4 ft long board so 4×5=20. Than he bought 3 of the 5ft boards 3×5=15. 20+15=35 ft worth of boards.

Matt brought total 8 boards out of which the 5 boards are of 4ft and 3 boards are of 5ft.

We have a guy named Matt who bought some boards to build a wooden deck. Some of the boards were 4 ft long and some of the boards were 5 ft long. He bought 35 ft of boards altogether.

We have to find out how many boards he bought all together.

The solution of an equation is the value at which the left hand side and right hand side of the equation equals to each other.

In the question, it is given that there are 4ft long and 5ft long boards and matt brought 35 ft of board all together.

Let us assume that the number of 4 ft boards he bought are = x and the number of 5ft boards be y, then according to question -

4x + 5y = 35

[tex]y = \frac{-4x + 35}{5} \\y=\frac{-4x}{5} + 7[/tex]

Now, all the points that lie on this line are the possible answers but the number of boards cannot be in decimal. Hence, the solution x = 5 and y=3, which will give us 4 x 5 + 5 x 3 which is equal to 35.

Hence, Matt brought 5 boards of 4ft and 3 boards of 5ft.
