5. Jerald is investigating the typical depreciation rate for the used automobile he intends to purchase next month. He has collected the following data about an automobile purchased in 1999 for 12,500. a. Using Jerald’s data, find the best-fit exponential equation for this deprecation using the substitution method. Must show work. b. Using the same data, get an equation using the calculator's regression feature. Then estimate the depreciated value of the automobile in 2010:

C. X > -1

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2x + 5 < 7

Step 2: Subtract 5 from both sides.

−2x + 5 − 5 < 7 − 5

−2x<2

Step 3: Divide both sides by -2.

−2x/−2 < 2/−2

x > −1

Answer: [tex]9 \frac{1}{2} x+5[/tex]

Step-by-step explanation:

In order to find the Perimeter, we add all the segments up.

 (2x-1)+(4x+3)+(x+2)+(2x+2)+(1/10x-1)+(2/5x)

=2x-1+4x+3+x+2+2x+2+1/10x-1+2/5x ⇔ Expand Parenthesis

=2x-1+4x+3+x+2+2x+2+1/10x-1+4/10x ⇔ Convert fractions into same                              

                                                                  denominator

=(2x+4x+x+2x+1/0x+4/10x)+(3-1+2+2-1) ⇔ Put like terms together

=(9x+1/2x)+5 ⇔ Combine like terms

=9 1/2 x +5

Hope this helps!! :)

Answer:

Step-by-step explanation:

Using the expression for calculating the sum of an AP as:

Tn = Sn - Sn-1

When n = 10

T10 = S10 - S9

Given that;

Sn = n²-3n

S10 = 10²-3(10)

S10 = 100 - 30

S10 = 70

S9 = 9² - 3(9)

S9 = 81 - 27

S9 = 54

Substitute the given values

T10 = S10 - S9

T10 = 70 - 54

T10 = 16

Hence the 10th term of the sequence is 16

Answer:

C

Step-by-step explanation:

Option c (20, 24, 26) doesn't follow the Pythagoras triplet, it is a not right-angle.

The right-angle triangle is a triangle in which the measure of two sides of a triangle is smaller than the longest side of the triangle.

To find the right angle triangle it should satisfy the Pythagoras theorem

a. 12, 16, 20

[tex]12^{2} +16^{2} = 144 + 256[/tex]

               = 400

[tex]20^{2}[/tex] = 400

Since it follows the Pythagoras triplet, it is a right-angle triangle.

b. 15, 36, 39

[tex]15^{2} +36^{2} \\= 1521[/tex]

[tex]39^{2} =1521[/tex]

Since it follows the Pythagoras triplet, it is a right-angle triangle.

c. 20, 24, 26

[tex]20^{2} + 24^{2} \\= 976[/tex]

[tex]26^{2} = 676[/tex]

Since it does not follow the Pythagoras triplet, it is a not right-angle triangle.

d. 30, 40, 50

[tex]30^{2} +40^{2} \\= 2500\\50^{2} = 2500[/tex]

Since it follows the Pythagoras triplet, it is a right-angle triangle.

Hence, option c doesn't follow the Pythagoras triplet, it is a not right-angle.

The probability that the Liam and Michael are 0.001422 as a fraction in lowest terms or a decimal rounded to the nearest millionth is 5 decimal.

Liam and Michael are going to play video games this afternoon.

Then, Liam going to play video games = 38

Michael going to play video games = 2

In 38 video games and 2 video games are exactly what Liam and Michael need.

So,

We can write,

Probability = [tex]\frac{2C_{2} }{38C_{2} }[/tex]

As only one case is possible,

That is, [tex]2C_{2}[/tex] = 1

Probability = 1/(38!/(38-2)!2!)

= 1/(38!/36!2!)

=( 2! * 36! )/38!

= (2! * 36! )/38!*37!*36!

= 2!/38!37!

= 1/19!37!

= 1/703

= 0.001422

Rounding to nearest million ( 5 decimal )

Required probability = 0.001422

Therefore,

The probability 0.001422 as a fraction in lowest terms or a decimal rounded to the nearest millionth is 5 decimal.

Answer:

r = 29.82

Step-by-step explanation:

r/7.1 = 4.2

r = 7.1 x 4.2

r = 29.82

Answer:

29.82

Step-by-step explanation:

First, we multiply all terms by the same number to get rid of the denominators.

71 x /71/10 = 71 x 42

Next, we cancel the multiplied terms in denominator.

10 = 71 x 4.2

Answer:

  73.5 km

Step-by-step explanation:

The magnitude can be found from the law of cosines. The angle between the two vectors is 140°, so the magnitude is ...

  c^2 = a^2 + b^2 -2ab·cos(C)

  c^2 = 32^2 +46^2 -2·32·46·cos(140°) ≈ 5395.2348

  c = √5395.2348 ≈ 73.452

The magnitude of the resultant vector is about 73.5 km.

Answer:

  WX = 33

  (x, y) = (2, 10)

Step-by-step explanation:

The hash marks tell you WX is a midline, so has the measure of the average of the two bases.

  WX = (PQ +SR)/2 = (27 +39)/2 = 66/2

  WX = 33

__

The hash marks also tell you ...

  PW = WS

  y +4x = 18 . . . . . . substitute the given expressions

and also

  QX = XR

  2y +x = 22 . . . . . substitute the given expressions

__

If you solve the first equation for y, you get ...

  y = 18 -4x

Substituting that into the second equation gives ...

  2(18-4x) +x = 22

  36 -7x = 22 . . . . . . . simplify

  14 = 7x . . . . . . . . . . . add 7x-22 to both sides

  2 = x . . . . . . . . . . . . divide by 7

  y = 18 -4(2) = 10 . . . find y using the above relation

The values of x and y are 2 and 10, respectively.

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.

Answer:

Step-by-step explanation:

The equation of the line that passes through the points (1, 50) and

(3, 120) is y = 35x + 15.

We have,

The point-slope form of a linear equation is given by:

y - y₁ = m(x - x₁)

Where (x₁, y₁) represents the coordinates of a point on the line, and m represents the slope of the line.

The slope (m) using the given points:

m = (y₂ - y₁) / (x₂ - x₁)

Substituting the values from the given points (1, 50) and (3, 120).

m = (120 - 50) / (3 - 1)

= 70 / 2

= 35

Use (1, 50)) and substitute its coordinates into the point-slope form:

y - y₁ = m(x - x₁)

y - 50 = 35(x - 1)

Simplifying further:

y - 50 = 35x - 35

y = 35x - 35 + 50

y = 35x + 15

Therefore,

The equation of the line that passes through the points (1, 50) and

(3, 120) is y = 35x + 15.

Side lengths that form a right triangle

Applying Pythagoras theorem

[tex]a^2 = b^2 + c^2[/tex]

Where a is the longest side.

So, we have:

[tex](a)\ 5, \sqrt 6, \sqrt{31[/tex]

[tex](\sqrt{31})^2 = 5^2 + (\sqrt 6)^2[/tex]

[tex]31 = 25 + 6[/tex]

[tex]31 = 31[/tex]

This forms a right triangle

[tex](b)\ \sqrt 5, \sqrt 5, 50[/tex]

[tex]50^2 = (\sqrt 5)^2 + (\sqrt 5)^2[/tex]

[tex]2500 = 5 + 5[/tex]

Answer:

  37°

Step-by-step explanation:

The diagonals of a rhombus are angle bisectors. Angle 1 matches the other half of angle L.

  ∠1 = 37°

Angle 2 is the complement, 53°, and angle 3 is the same as angle 2, 53°.

The diagonals of a rhombus are perpendicular bisectors of each other, so angle 4 is 90°.
