After 10 years, the car will be worth 0.54 of the price when Rob purchases it. The result is obtained using the exponential depreciation equation.

The depreciation can be calculated by the exponential depreciation equation.

y = P (1 - r)ˣ

Where

If given

How much will the car be worth after 10 years?

The depreciation rate would be

r = 6%

r = 6/100

r = 0.06

So, after 10 years, the car would be worth

y = P (1 - r)ˣ

y = P (1 - 0.06)¹⁰

y = P (0.94)¹⁰

y = P (0.54)

y = 0.54P

Hence, after 10 years, the car will be worth 0.54 of its original price.

If the equation is 2r+10=22

Subtracting -10 to both sides:

2r = 22 - 10

Subtracting numbers:

2r = 12

Dividing both sides by 2:

r = 12/2

Simplifying:

r=6

Answer:

slope = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

3x + y = 8  ( subtract 3x from both sides )

y = - 3x + 8 ← in slope- intercept form

with slope m = - 3

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex]

The perimeter of the polygon with the vertices is: 17.5 units.

The perimeter of a polygon is the sum of all the sides of the polygon. To find the perimeter of a polygon with coordinates given for its vertices, we have to apply the distance formula to find the length between each of the vertices of the polygon.

The distance formula is d = [tex]\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex].

Given:

J(-5, 3)

K(-2, 1)

L(3, 4)

Find JK:

JK = √[(−2−(−5))² + (1−3)²]

JK = √13

JK = 3.6 units

Find KL:

KL = √[(−2−3)² + (1−4)²]

KL = √34

KL = 5.8 units

Find JL:

JL = √[(−5−3)² + (3−4)²]

JL = √65

JL = 8.1 units

Perimeter = 3.6 + 5.8 + 8.1

Perimeter = 17.5 units.

Answer: A z=9

Step-by-step explanation:

Answer:

z = 12

Step-by-step explanation:

To understand the equation, you must first know that m∠a = 108°. It equals that because a regular five-sided polygon has an interior angle of 108° each.

Next, you would want to group all constants to the right side of the equation. By doing so, you want to subtract 72 from both sides.

(3z + 72) - 72 = 108 - 72

3z = 36

Lastly, you want to isolate the z by dividing 36 by 3.

z = 36 ÷ 3

z = 12

The baker has 13/3 pounds of sugar.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

We have been given two fractions.

The three containers have 3/4 pounds of sugar and fourth one have 1/2 pounds of sugar.

To find the total sugar, we have to add both the fractions

Total pounds of sugar = Sugar in three containers + sugar in fourth container

= 3/4 + 1/3

= (9 + 4)/3

= 13/3 pounds

So, the total sugar the baker has is 13/3 pounds.

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

here (x₁, y₁ ) = C (1, 9 ) and (x₂, y₂ ) = D (7, - 7 ) , then

Answer:

Option 1. This is a vertical pair of angles because they are two nonadjacent (not next to each other) angles formed by intersecting lines. The sides of one angle are the opposite rays to the sides of the other angle. (Angle 5=Angle 7)

Option 2 and 4 are wrong as the angles are not created by a set of parallel lines and a transversal.

Option 3 is wrong as the angles are not adjacent.

Option 5 is wrong as the angles do not have a sum of 90°.

The Explicit Formula is a(n) = 27×[tex](\frac{2}{3})^n^-^1[/tex]

Given,

The first four terms are 27, 18, 12, 8.

The values of u and v that makes △QRS and △IKJ congruent triangles are u = 7 and v = 3

The triangles are given as

△QRS and △IKJ

The statement △QRS≅△IKJ means that

The triangles △QRS and △IKJ are congruent triangles

This means that the corresponding sides are congruent

So, we have the following equations:

v + u + 15 = 10u - 15v

-4u + 2v + 99 = 7v + 8u

Evaluate the like terms

So, we have

9u - 16v = 15

12u + 5v = 99

Make u the subject in 12u + 5v = 99

So, we have

u = (-5v + 99)/12

Substitute u = (-5v + 99)/12 in 9u - 16v = 15

9(-5v + 99)/12 - 16v = 15

So, we have

9(-5v + 99) - 192v = 180

Open brackets

-45v + 891 - 192v = 180

Evaluate the like terms

-237v = -711

Divide by -237

v = 3

Substitute v = 3 in u = (-5v + 99)/12

u = (-5 x 3 + 99)/12

Evaluate

u = 7

Hence, the values are u = 7 and v = 3

y=4 is a horizontal line, where all values of y are 4, regardless of x.  A horizontal line has a slope of 0.  [Y does not depend on x].

That leaves us with y =0x + b

For this line to go through point (-3,2), it would have to have a y-intercept (b) of 2 [b is the value of y when x=0].  Since y=0 regardless of x, b must be 2.
