Answer :after four years the price of car depreciate

Final answer:

It will take approximately 4 years for the car to depreciate to $4520 using the declining-balance method of depreciation with a depreciation rate of 30%.

Explanation:

To calculate the number of years it would take for the car to depreciate to $4520, we can use the declining-balance method of depreciation. The declining-balance method is based on a fixed percentage of the remaining value of the asset. In this case, the rate of depreciation is 30%, so the car's value will decrease by 30% each year.

Let's start by finding the value of the car after one year. We can use the formula:

Value after one year = Initial value - (Rate of depreciation * Initial value)

Plugging in the values, we get:

Value after one year = $18820 - (0.3 * $18820) = $18820 - $5646 = $13174

Now, let's find the value after the second year:

Value after two years = $13174 - (0.3 * $13174) = $13174 - $3952.2 = $9221.8

We continue this process until we reach a value of $4520. By the time the car's value reaches $4520, it will have taken approximately 4 years.

To solve the system of equations, we can use the matrix tool. The solution to the system of equations is (1, 1.5) as an ordered pair.

To solve the system of equations using matrices, you can represent the coefficients and constants as matrices and then use matrix operations. The system of equations can be represented in matrix form as:

[A] [X] = [B],

Where:

[A] is the coefficient matrix,

[X] is the variable matrix (containing x and y),

[B] is the constant matrix.

For the given system of equations:

4x + y = 0

8x - y = 6

The coefficient matrix [A], variable matrix [X], and constant matrix [B] are:

[A] = [[4, 1],

[8, -1]]

[B] = [[0],

[6]]

Now, to solve for [X], you can use matrix multiplication:

[A] [X] = [B]

[X] = [A]⁻¹ [B]

First, calculate the inverse of [A]:

[A]⁻¹ = [[-1/12, -1/12],

[1/4, 1/4]]

Now, multiply [A]⁻¹ by [B]:

[X] = [[-1/12, -1/12],

[1/4, 1/4]] [0, 6]

[tex][X] = [(-1/12 \times 0 + -1/12 \times 6),[/tex]

[tex](1/4 \times 0 + 1/4 \times 6)][/tex]

Simplify:

[X] = [-(-1), 1.5)]

[X] = [1, 1.5]

So, the solution to the system of equations is (1, 1.5) as an ordered pair.

The ball reaches the ground after 7.76 s

Step-by-step explanation:

The motion of the ball along the vertical direction is a free fall motion, which is affected by the force of gravity only; therefore it is a uniformly accelerated motion (=constant acceleration), so we can use the following suvat equation:

[tex]s=ut-\frac{1}{2}gt^2[/tex]

where

s is the displacement

u is the initial vertical velocity

[tex]g=9.8 m/s^2[/tex] is the acceleration due to gravity

t is the time

In this problem,

u = 38 m/s

Also, we want to find the time t at which the ball hits the ground again: so, when the displacement becomes zero again,

s = 0

Therefore the equation becomes:

[tex]0=38t-\frac{1}{2}9.8t^2\\0=38t-4.9t^2[/tex]

And solving for t,

[tex]t(38-4.9t)=0[/tex]

we have two solutions:

t = 0 (instant at which the ball is kicked)

[tex]38-4.9t=0\\t=\frac{38}{4.9}=7.76 s[/tex]

which is the solution to the problem.

It will take 3 hours 6 minutes 40 seconds for the cars to be 420 miles apart.

Step-by-step explanation:

Step 1; The cars are traveling in the opposite direction at different speeds. One is going north at a speed of 75 mph while the other is going 60 mph. So for every hour, the cars are traveling they increase the distance between in between themselves by 75 miles + 60 miles = 135 miles.

Step 2; Assume that in x hours the distance between them is 420 miles. To calculate x we divide the distance to be traveled by the distance being traveled every hour.

x = distance to be covered / distance being traveled every hour

= 420 / 135 = 3.11 hours

We multiply the 0.11 hours with 60 to convert it into minutes. 0.11 × 60 = 6.66 minutes and if we do the same for seconds, 0.66 minutes × 60 = 40 seconds.

Answer:

The length of an edge of the cube = x = [tex]\sqrt[3]{1000}[/tex] = 10 feet

Step-by-step explanation:

i.) A cube has a volume of 1000 cubic feet.

ii) A cube has edges which are all the same length, let us say that the length of an edge of the cube = x feet.

iii) therefore the volume of the cube is = [tex]x^{3}[/tex] = 1000 cubic feet

iv) therefore the length of an edge of the cube = x = [tex]\sqrt[3]{1000}[/tex] = 10 feet

Final answer:

The length of an edge of a cube with a volume of 1000 cubic feet is 10 feet. If each smaller cube has linear dimensions one tenth those of the larger cube, then the volume of each smaller cube is 1 cubic foot.

Explanation:

The volume of a cube is calculated by raising the length of one of its edges to the power of three (cubing it). Since we know the volume of the cube is 1000 cubic feet, we can determine the length of an edge by finding the cube root of the volume. The cube root of 1000 cubic feet is 10 feet, so the length of an edge of the cube is 10 feet.

To find the volume of the smaller cubes mentioned, we note that if their dimensions are one tenth of the larger cube, then each side of a smaller cube will be 10 feet divided by 10, which is 1 foot. The volume of each small cube is then 1 foot cubed, which is 1 cubic foot.

For a visual reference, imagine a larger cube divided evenly into smaller cubes, where the length of each side of the big cube is ten times that of the smaller ones. The result is that each smaller cube's volume is the original volume divided by the cube of 10 (since there are 10 layers of small cubes along each dimension of the big cube).

Option B, y = 4.6x + 5.2

Step-by-step explanation:

Slope-intercept form:  y = mx + b

Step 1:  Use those two points to get slope

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

m = [tex]\frac{42 - 19}{8 -3}[/tex]

m = [tex]\frac{23}{5}[/tex]

m = 4.6

Step 2:  Find the y - intercept

Use point slope formula:  (y - y1) = m(x - x1)

(y - 19) = 4.6(x - 3)

y - 19 + 19 = 4.6x - 13.8 + 19

y  = 4.6x + 5.2

Answer:  Option B, y = 4.6x + 5.2

  B.  T<-4, -2>, r(90°, O)

Step-by-step explanation:

Point A' is 4 units left and 2 units down from point A, so the translation is T<-4, -2>.

Segment C"D" is on the -x axis, 90° counterclockwise from segment C'D' on the +y axis. Since rotation angles are measured the same way other angles are measured (positive is CCW), the rotation is +90° about the origin.

The congruence transformation that maps the quadrilateral ABCD to A''B''C''D'' is [tex]T_{ < -4, \, -2 > } \circ T_{90^{\circ}}, origin > (ABCD)[/tex] which corresponds with the option B.

B. [tex]T_{ < -4, \, -2 > } \circ T_{90^{\circ}}, origin > (ABCD)[/tex]

A congruent transformation, which is also a rigid transformation is one in which the size and shape of the original figure is preserved.

The coordinates of the vertices of the quadrilaterals ABCD and A'B'C'D' indicates that the transformation from the quadrilateral ABCD to the quadrilateral A'B'C'D' is a translation of 4 units to the left and 2 units downwards, which can be expressed as T<-4, -2>

The side D'C' in the quadrilateral A'B'C'D' is vertical while the side D''C'' in the quadrilateral A''B''C''D'' is horizontal and due to the order of the letters D'' and C'' in D''C'' arranged from left to right suggesting a 90° counterclockwise rotation about the origin, which is a T90°, origin

The congruence transformation that maps ABCD to A''B''C''D'' therefore is the option B, [tex]T_{ < -4, \, -2 > }\circ T_{90^{\circ}}, origin > (ABCDE)[/tex]
