The depreciation equation is given by

where x represents the number of years. Here, the initial value of the car corresponds to x=0, then we have

After one year, the car value corresponds to x=1, that is,

Now, let's find the depreciation percentage by means of a rule of three:

so we have

So the difference between 100% and 86% is 14% This means Nichole's car depreciate 14% each year

Answer:its D

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

Since 7 into 42 is six we know the answer can't be 7 because it's too high. We can also rule out 6 because 6 times 7.94 is more than 41. The first answer choice is wrong because if you take away the .94, 7 times 4 is 28 which is pretty far from 41. If you multiply 5 and 7, it comes out to 35. That's significantly closer than four.

Answer:

B and C

Step-by-step explanation:

I think that you mean -1 -1.  That would equal -2

-2 is an integer and a rational number.

An integer are the whole numbers 0,1,2,3 and so on and their opposites, -1, -2, -3 ,-4 and so on

Rational number is when you can write a number as an integer over and integer.  You can write -2 as  -2/1

I did it in the test

The decimal is equal to (294117647)/(1000000000).

Standard deviation of population mean is 0.33.

Why is there a standard deviation?

it is shown that 5% values are over 2.1 pounds and 5% are under 1.9 pounds

so stastically that means

P( X > 2.1,  μ; σ) = 0.05 and P( X 1.9; μ; σ) = 0.05

where  μ is mean of the sample and σis the standard deviation of the sample.

so mean can be calculated easily μ = (2.1 + 1.9)/2 = 2.0

and as we can interpret P(1.9 <x < 2.1; 2.0; σ) = 0.90 by normal distribution the Z value for 90% confidence interval is 1.65

so σ = (2.1 -2) /1.65 = 0.06

standard deviation of the sample mean= 0.06

and by that standard deviation of population mean = 0.06 * (30) 0.5  = 0.33

The complete question is -

A production process is checked periodically by a quality control inspector. the inspector selects simple random samples of 30 finished products and computes the sample mean product weight. If test results over a long period of time show that 5% of the values are over 2.1 pounds and 5% are under 1.9 pounds, what are the mean and the standard deviation for the population of products produced with this process? What is the population mean? (to 1 decimal) What is the population standard deviation (to 2 decimals)?

Answer:

(i) 7 + 4√2  cm^2.

(ii) 50 - 8√2  cm^2.

Step-by-step explanation:

(i)

Area = (3 + √8)(5 - 4/√2)

= 3(5 - 4/√2) + √8(5 - 4/√2)

= 15 - 12/√2 + 5√8 - 4√4

= 15 - 8 -( 12√2)/2 + 5*(2√2)

= 7 - 6√2 + 10√2

= 7 + 4√2.

(ii)

Area of the square

= AC^2

= (3 + √8)^2 + (5 - 4/√2)^2            (By Pythagoras)

= 9 + 6√8 + 8 + 25 - 40/√2 + 16/2

= 9 + 8 + 8 + 25 + 12√2 - 20√2

= 50 - 8√2.

There will  be no interval of time when Josue has more in savings than Arianna, they have same savings is after 4 weeks

Step one:

For Josue

initial savings balance= $70

weekly savings = $9

Let J represent amount of money Josue has saved and  t the number of weeks after the beginning of the year

The total amount in the savings after t weeks is

J=9t+70-------1

For Arianna

initial savings balance= $30

weekly savings = $19

Let A represent the amount of money Arianna has saved and  t the number of weeks after the beginning of the year

The total amount in the savings after t weeks is

J=19t+30---------2

Step two

equation 1 and 2 to find t

9t+70=19t+30

9t-19t=30-70

-10t=-40

divide both sides by 10

t=4

t=4 weeks

so after 4 weeks Josue and Arianna will have the same amount of money

For Josue t=4

J=9(4)+70-------1

J=36+70

J=$106

For Arianna t=4

A=19(4)+30---------2

A=76+30

A=$106

The two equations above shows that after 5 weeks their savings will be $106.

The largest number of rods that the pole can be cut into is 86.

Given:

Length of Metal Pole = 500 cm

The pole is cut into rods.

Length of each rod = 5.8 cm

To determine the number of rods we can divide the total length of the pole by the length of each rod.

Number of rods that the pole can be cut into = (Length of Metal Pole) ÷ (Length of each rod )

⇒ Number of rods = 500 ÷ 5.8 = 86.2 ≈ 86

Therefore, the largest number of rods that the pole can be cut into is 86.

Subtract 3x from both sides,

           4y = -3x + 64

Now, divide both sides by 4,

AE and BE are congruent lines or we can say lines with same length.

What are congruent lines?

Congruent line segments are geometrical figures in one dimension with identical dimensions. In terms of congruent lines, the word "congruent" refers to the equality of the two line segments. When two lines are the same length, they are said to be congruent.

As given in the question,

AC = BD, and

EC = ED

We can see in the figure that:

AC - EC = AE ___(1)

BD - ED = BE ___(2)

Substituting the value of AC and EC in equation (1):

AE = BD - ED ___(3)

From equations (2) and (3), we can conclude that,

AE = BC

Therefore, AE and BE are congruent lines.

For the first question mark, 7 is half of 14, and half of 8 is 4, so they would be the same ratio, and then for the second, 12 to 24 is just one half, meaning you would need to find double 32, which is just 64

Compute the Laplace transform of [tex]f(t)=t^n[/tex], where [tex]n[/tex] is a non-negative integer.

[tex]\displaystyle L\left\{t^n\right\} = I_n = \int_0^\infty t^n e^{-st} \, dt[/tex]

Integrate by parts with

[tex]u=t^n \implies du = nt^{n-1} \, dt[/tex]

[tex]dv = e^{-st} \, dt \implies v = -\dfrac1s e^{-st}[/tex]

[tex]\displaystyle I_n = \frac ns \int_0^\infty t^{n-1} e^{-st} \, dt = \frac ns I_{n-1}[/tex]

By substitution,

[tex]\displaystyle I_n = \frac ns I_{n-1} = \frac{n(n-1)}{s^2} I_{n-2} = \cdots = \frac{n(n-1)\cdots(n-(k-1))}{s^k} I_{n-k}[/tex]

so that for [tex]k=n[/tex], we end up with

[tex]\displaystyle I_n = \frac{n(n-1)\cdots1}{s^n} I_0 = \frac{n!}{s^n} \int_0^\infty e^{-st} \, dt = \frac{n!}{s^{n+1}}[/tex]

We then have the inverse transform relation

[tex]\displaystyle L^{-1}\left\{ \frac1{s^n} \right\} = \frac{t^{n-1}}{(n-1)!}[/tex]

and so

[tex]L^{-1}\left\{ \dfrac1{s^3} + \dfrac1s \right\} = \dfrac{t^2}{2!} + \dfrac{0!}{t^0} = \boxed{\dfrac{t^2}2 + 1}[/tex]

Algebra is a system for computation using letters or other symbols to represent numbers, with rules for manipulating these symbols.

The cost of the tomatoes for a number of packages = 4.45p

If the store sold 2 1/4 pounds of tomatoes

The cost of the tomatoes for a number of packages = 4.45p

= 4.45(2 1/4)

= 4.45(9/4)

9. Option b. The two lines are perpendicular to each other

  Given:

   6x+10y = 20

   5x- 3y = 21

Consider the first line,

10 y = -6x+ 20

y = -3/5 x + 2

This is of the form y = mx+ b

where, slope =m = - 3/5

Consider the second line,

5x- 3y = 21

3y = 5x- 21

y = 5/3 x - 21

This is of the form y = mx+ b

where, slope= m = 5/3

Since the slopes of the two lines are negative reciprocals ,they are perpendicular.

10. Option a. The equation of the line  passing through (2, -9) with a slope -5 is y = - 5x + 1

Given:

slope = m= -5

point = (2,-9)

We know that ,the slope -intercept form is given by ,

y = mx+ b ---(1)

Substituting the given values in (1)

-9 = -5(2)+b

10- 9 = b

b = 1

Substituting m and b in (1)

y = -5x+1

Thus, the slope-intercept form equation of the line is y = -5x + 1

11. The  equation of the line perpendicular to y= -2x+8 and passing through the point (4,-7) is y = 1/2x- 9

Given:

line = y = -2x+8

point = (x, y)= (4, -7)

The given equation is of the form,

y = mx+ b  ---- (1)

m = -2

The line perpendicular to this line will have a negative reciprocal slope,

m = 1/2  

The new line is of the form,

y = 1/2 x+ b   ----(2)

Substituting the given point (4, -7) in (2)

- 7= 2 + b

b = - 9

Substituting b in (2)

y = 1/2x- 9 is the perpendicular line equation

12.  The  equation of the line parallel to 3x- 2y = 14 and passing through the point (-6,-11) is y = 3/2 x -2

Given:

line = 3x- 2y = 14

point = (x, y)= (-6,-11)

The slope - intercept form of the given line is ,

2y = 3x- 14

y = 3/2x - 7  

slope = m = 3/2

The line parallel to this line will have the same slope,

m = 3/2  

The new line is of the form,

y = 3/2 x+ b   ----(1)

Substituting the given point (-6, -11) in (1)

- 11= -9 + b

b = - 2

Substituting b in (1)

y = 3/2 x -2 is the parallel line equation.
