If the value of the 2022 Jeep Wrangler Rubicon depreciates at a rate of 9.7% per year, then its value after t years can be modeled by:

V(t) = 67,035(1 - 0.097)^t

Simplifying the right side:

V(t) = 67,035(0.903)^t

Therefore, the function that models the car's value, V, t years since 2022 is V(t) = 67,035(0.903)^t.

The surface area of the composite figure is 20048 sq. yd.

The formula SA = 2lw + 2lh + 2wh can be used to get the surface area (SA) of a rectangular prism, where l, w, and h are the length, width, and height of the prism, respectively. The formula determines the areas of the rectangular prism's six faces: the four sides, which are identical rectangles with areas of lh or wh, and the top and bottom, which are also identical rectangles with areas of lw each.

The composite figure can be divided into two parts one rectangular prism and a trapezium prism.

The surface area of the rectangular prism is given by:

2(lb + bh + hl)

Substituting the values we have:

SA = 2(62 yd x 55 yd + 55 x 25 + 25 x 62)

SA = 2(3410 + 1375 + 1550)

SA = 2(6335) = 12670 sq. yd.

Now, the area of the trapezoidal prism is:

SA = (b1 + b2)h + (b1 + b2 + a + b) l

Substituting the values b1 = 55 yd, b2 = 7 yd, h = 7 yd, a = b = 25 yd, l = 62 yd we have:

SA = (55 + 7)(7) + (55 + 7 + 25 + 25)62

SA = 434 + 6944

SA = 7378 sq. yd

Now, the surface area of the composite figure is:

SA =  12670 + 7378 = 20048 sq. yd.

Hence, the surface area of the composite figure is 20048 sq. yd.

The second time when harry feel like consuming 17 kg of sheep after he wakes up is equal to 39.7 hours ( round to nearest tenth of an hour).

Function is equal to

H (t) = 12 sin (2/24t) +15

Where  H(t) models the weight of sheep in kg that Harry like to swallow in 't' hours after wakes up.

't' in radians.

Harry wants to consumes 17kg

⇒ H(t) = 17 for t.

Substituting the given expression for H(t), we get,

⇒ 12 sin(2/24 t) + 15 = 17

⇒ 12 sin(2/24 t) = 2

⇒ sin(2/24 t) = 1/6

⇒ 2/24 t = sin^(-1)(1/6)

We know that sin^(-1)(1/6) = 0.167

Substitute the value we get,

⇒ t = 12 × 0.167

⇒ t = 2.004 radians

This gives us the first time after Harry wakes up that he feels like consuming 17 kg of sheep.

For the second time,

Add one full period to the first time, since the function H(t) has a period of 12π/2 = 6π.

The second time is,

t = 2.004 + 6π

  = 2.004 + 6×3.14

 = 20.844 radians

To round to the nearest tenth of an hour,

Since there are 12 hours in a full revolution.

Convert radians to hours by dividing by 2π and then multiplying by 12.

t = 20.844/(2π) ×  12

 = 3.31 × 12 hours

 = 39.69

  = 39.7 (rounded to the nearest tenth)

Answer:

Step-by-step explanation:

Answer:

To write a rational expression with denominator 6b that is equivalent to 1/3, we need to find a value to multiply both the numerator and denominator of 1/3 by that will result in a denominator of 6b.

We can start by writing 1/3 as a fraction with denominator 1:

1/3 = 1/3 * 1/1

Next, we can multiply both the numerator and denominator by 2b:

1/3 * 2b/2b = 2b/6

Simplifying the fraction 2b/6, we get:

2b/6 = b/3

Therefore, the rational expression with denominator 6b that is equivalent to 1/3 is b/3.

The distance between the points (2, -4) and (2, 7) is 11 units.

What is distance?

In mathematics, the distance between two points is a numerical value that represents the amount of space between them. The distance between two points is calculated using the Pythagorean theorem, which applies to any two points in a two-dimensional or three-dimensional space.

The two points have the same x-coordinate of 2, so they lie on a vertical line. To find the distance between them, we need to find the difference between their y-coordinates.

The y-coordinate of the first point is -4 and the y-coordinate of the second point is 7. Therefore, the difference between the y-coordinates is:

7 - (-4) = 7 + 4 = 11

So the distance between the two points is 11 units.

Therefore, the distance between the points (2, -4) and (2, 7) is 11 units.

Answer: They both intersect once.

Step-by-step explanation: Solving for x, we get:

3x = 0

x = 0

Now we can substitute x = 0 into either equation to find the y-coordinate:

y = 2(0) + 4 = 4

So the two lines intersect at the point (0,4).

Therefore, the graphs of the equations y = 2x + 4 and y = −x + 4 intersect once.

Answer:

It intersects once.

Step-by-step explanation:

To plot y = 2x + 4, you start at the y-intercept which is 4. Then you go up 2 times, and to the right once.

To plot y = -x + 4, you start at the y-intercept which is also at 4. Then you go down once and to the right one time.

The graph will intersect at (0, 4).

The ball will hit the ground after 4 seconds (x2 = 4).

Given the formula h(x) = -16x^2 + v0x + h0, we can plug in the values for the initial velocity (v0) and the initial height (h0) to find the equation that describes the ball's height as a function of time.

v0 = 64 ft/s (initial velocity)

h0 = 12 ft (initial height)

Now, we can write the function for the ball's height:

h(x) = -16x^2 + 64x + 12

To find when the ball hits the ground, we need to solve for x when h(x) = 0:

0 = -16x^2 + 64x + 12

This is a quadratic equation, and we can solve it using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = -16, b = 64, and c = 12.

x = (-64 ± √(64^2 - 4*(-16)12)) / 2(-16)

First, we find the discriminant (b^2 - 4ac):

64^2 - 4*(-16)*12 = 4096 + 768 = 4864

Now we can plug the discriminant back into the quadratic formula:

x = (-64 ± √4864) / (-32)

We have two possible solutions:

x1 = (-64 + √4864) / (-32)

x1 = (-64 + 64) / (-32)

x1 = 0

x2 = (-64 - √4864) / (-32)

x2 = (-64 - 64) / (-32)

x2 = 128 / 32

x2 = 4

Since x1 = 0 represents the initial time when the ball is kicked, we discard this solution.

Therefore, the ball will hit the ground after 4 seconds (x2 = 4).

The final absolute value inequality that represents the solution set x ≤ -9 or x ≥ -5 is |x + 7| ≥ 2.

If the absolute value expression is greater than or equal to a number (e.g. |x| >= 5).

We can write it as two separate inequalities: x >= 5 or x <= -5.
The absolute value expression is less than or equal to a number (e.g. |x| <= 3)

We can write it as the single inequality: -3 <= x <= 3.
Using these rules:

We can write an absolute value inequality that has the solution set x <= -9 or x >= -5200 as follows:
| x + 2604 | >= 5193
To see why this works,

Let's first look at the case where x is less than or equal to -9. In this case, we have:
x + 2604 <= -9
x <= -2613
Plugging this into our inequality:
| -2613 | >= 5193
Which is true, since |-2613| = 2613 >= 5193.
Now let's look at the case where x is greater than or equal to -5200. In this case, we have:
x + 2604 >= -5200
x >= -7804
Plugging this into our inequality, we get:
| -7804 | >= 5193
Which is also true, since |-7804| = 7804 >= 5193.
Therefore, the inequality | x + 2604 | >= 5193 has the solution set x <= -9 or x >= -5200, as desired. I hope this helps! Let me know if you have any other questions.
Midpoint = (-9 + (-5)) / 2 = -7
The absolute value inequality will have the form |x - (-7)|.
|x + 7| ≥ 2, since the distance between -9 and -7 is 2.
|x + 7| ≤ -2, since the distance between -5 and -7 is -2.
However,

An absolute value cannot be negative, so the second inequality doesn't make sense. Therefore, we'll only use the first inequality.

10 (c) the maximum height is 4

11 (b) the solutions of 16x² - 64 = 0  are  -4 and 4

9) To find the time it takes the rocket to hit the ground, we need to find the value of s when h(s) = 0 since h(s) represents the height of the rocket.

So we need to solve the equation: -3s^2 + 6s + 45 = 0.

Factoring, we get -3(s - 5)(s + 3) = 0. So s = 5 or s = -3. Since time cannot be negative, we take s = 5.

Therefore, the answer is (c) 5.

10 ) The maximum height of the rocket occurs at the vertex of the parabola given by the function h(s) = -3s^2 + 6s + 45. The s-coordinate of the vertex is given by s = -b/2a, where a = -3 and b = 6. So s = -6/-6 = 1. Therefore, the answer is (a) 1.

11) We can solve the equation 16x² - 64 = 0 by factoring out the greatest common factor, which is 16: 16(x² - 4) = 0.

Then, we can factor the quadratic expression as a difference of squares: 16(x + 2)(x - 2) = 0. Therefore, the solutions are x = -2 and x = 2, and the answer is (b) -4 and 4.

It will take John approximately 17 months to pay off the balance.

What is simple interest?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Assuming that John does not use the credit card for any other purchases and that the credit card company uses a simple interest calculation method, we can use the following steps to calculate the number of months it will take John to pay off the balance:

Calculate the monthly interest rate by dividing the annual percentage rate (APR) by 12:

Monthly interest rate = 19% / 12 = 0.01583

Calculate the monthly finance charge by multiplying the outstanding balance by the monthly interest rate:

Monthly finance charge = $2000 x 0.01583 = $31.66

Subtract the monthly payment from the monthly finance charge to get the amount that will be applied to the outstanding balance:

Payment applied to balance = $150 - $31.66 = $118.34

Divide the outstanding balance by the payment applied to balance to get the number of months it will take to pay off the balance:

Number of months to pay off balance = $2000 / $118.34 = 16.9

(rounded up to the nearest whole number)

Therefore, it will take John approximately 17 months to pay off the balance.

Therefore, the statement "The sample mean absolute deviation is likely to be higher for the samples with lower satisfaction rates" would be the BEST description of the MAD for this data set.

To calculate the mean absolute deviation (MAD), we first need to find the mean of each sample.

Sample 1:[tex]17/25 = 0.68[/tex]

Sample 2: [tex]12/25 = 0.48[/tex]

Sample 3: [tex]14/25 = 0.56[/tex]

Sample 4: [tex]9/25 = 0.36[/tex]

Next, we calculate the deviation of each observation from its respective sample mean:

Sample 1: |0.68 - x1|, |0.68 - x2|, ..., |0.68 - x25|

Sample 2: |0.48 - x1|, |0.48 - x2|, ..., |0.48 - x25|

Sample 3: |0.56 - x1|, |0.56 - x2|, ..., |0.56 - x25|

Sample 4: |0.36 - x1|, |0.36 - x2|, ..., |0.36 - x25|

where xi is the satisfaction rating (0 or 1) of the Ith customer in the sample.

The MAD is the average of these deviations:

MAD = (|0.68 - x1| + |0.68 - x2| + ... + |0.36 - x25|)/100

Since we don't know the actual ratings of the customers, we cannot calculate the MAD exactly. However, we can say that the MAD is likely to be higher for samples 2 and 4, which have lower satisfaction rates, compared to samples 1 and 3, which have higher satisfaction rates. Therefore, the statement "The sample mean absolute deviation is likely to be higher for the samples with lower satisfaction rates" would be the BEST description of the MAD for this data set.

Answer:

x<-1/5

Step-by-step explanation:

Imma assume the _ is a - soo

3x-1<-2x

5x<-1

x<-1/5

Let's use the variable x to represent the list price of the car.

The total cost your cousin paid for the car is the list price plus a 7% sales tax on the list price, plus $450 in additional fees.

We can write this as an equation:

Total cost = List price + 0.07(List price) + 450

We know that the total cost your cousin paid was $12,755, so we can substitute that into the equation:

12,755 = x + 0.07x + 450

Simplifying the right side:

12,755 = 1.07x + 450

Subtracting 450 from both sides:

12,305 = 1.07x

Dividing both sides by 1.07:

x = 11,500

Therefore, the list price of the car your cousin bought was $11,500.

The list price of the car your cousin bought was $11,500.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let's start by setting up an equation to represent the total cost of the car:

Total cost = List price + 7% of List price + $450

We know that the total cost is $12,755, so we can substitute that in:

$12,755 = List price + 0.07(List price) + $450

Simplifying this equation, we get:

$12,755 = 1.07(List price) + $450

Subtracting $450 from both sides, we get:

$12,305 = 1.07(List price)

Dividing both sides by 1.07, we get:

List price = $11,500

Therefore,

The list price of the car your cousin bought was $11,500.

angle opposite 16 = [tex]sin-1(\sqrt(1 - cos2(angle opposite 16))[/tex] angle opposite 16 = [tex]sin-1(\sqrt(1 - (-0.442)2)[/tex]angle opposite 16 = 118.7 degrees

In Euclidean geometry, a parallelogram is a simple quadrilateral with two sets of parallel sides. A parallelogram is a kind of quadrilateral in which both sets of opposite sides are parallel and equal. Parallelograms are classified into four types, three of which are unique. The four distinct shapes are parallelograms, squares, rectangles, and rhombuses. A quadrilateral is a parallelogram when it has two sets of parallel sides. The opposing sides and angles of a parallelogram are both the same length. The internal angles on the same side of the horizontal line are also angles. The total number of internal angles is 360.

To calculate the area of a parallelogram, multiply the base by the height. Nevertheless, the height is not mentioned in this situation. Alternatively, we may use the following formula to calculate the area of a parallelogram:

The area is defined as follows: base x height x sin (angle between base and height)

[tex]16^2 = 13^2 + 13^2 - 2(13)(13) (13)[/tex]

cos(opposite angle 16) 256 = 338 − 338

cos(opposite angle 16) cos(opposite angle 16) = -0.442

We know the angle is between 90 and 180 degrees since the cosine is negative. To get the angle in that range, we may use the inverse sine function:

angle opposite 16 = [tex]sin-1(\sqrt(1 - cos2(angle opposite 16))[/tex] angle opposite 16 = [tex]sin-1(\sqrt(1 - (-0.442)2)[/tex]angle opposite 16 = 118.7 degrees
