Answer:

the monthly car payment is $722.91

Step-by-step explanation:

To find the monthly car payment, we need to use the formula for the monthly payment of a loan:

P = (Pr(1+r)^n)/((1+r)^n - 1)

where P is the monthly payment, P is the loan principal (the total cost of the car including tax and license), r is the monthly interest rate, and n is the total number of payments (the number of years multiplied by 12 months per year).

First, we need to convert the annual interest rate of 4.4% to a monthly interest rate. We divide 4.4% by 12 to get:

r = 0.044/12 = 0.0036667

Next, we need to calculate the total number of payments. Since the loan is for 4 years and there are 12 months in a year, the total number of payments is:

n = 4 years x 12 months/year = 48

Now we can substitute the values into the formula:

P = (31795.66(0.0036667)(1+0.0036667)^48)/((1+0.0036667)^48 - 1)

Using a calculator, we get:

P = $722.91 (rounded to the nearest cent)

Therefore, the monthly car payment is $722.91.

The length of Jennifer's garden is 25 feet.

A rectangle is a geometric shape that has four sides and four right angles (90 degrees) with opposite sides being parallel and equal in length. It is a type of quadrilateral, a polygon with four sides. The length of the sides that are parallel to each other is called the base, and the length of the sides that are perpendicular to the base is called the height.

Let's suppose that the length of the garden is x feet.

We know that the width of the garden is 5 feet, so the total length of the edging required for the two widths is 2 x 5 = 10 feet.

The remaining edging is used for the two lengths of the garden, so we can write an equation based on the total length of the edging:

2(5 + x) = 60

Simplifying this equation, we get:

10 + 2x = 60

2x = 50

x = 25

Step-by-step explanation:

The 90% confidence interval for the mean pressure is calculated equivalent to (6.39, 7.99).

A t-distribution table is a statistical table that lists critical values of the t-distribution for various levels of significance and degrees of freedom. The t-distribution is a probability distribution that is used when the sample size is small or when the population standard deviation is unknown.

The table is organized by degrees of freedom (df), which is calculated as n-1, where n is the sample size. It also lists different levels of significance, usually ranging from 0.01 to 0.5 or more. The critical values are listed in the table corresponding to the degrees of freedom and the significance level. To use a t-distribution table, you need to know the degrees of freedom and the level of significance.

To calculate the 90% confidence interval for the mean pressure, we can use the formula:

CI = X' ± Z*(σ/√n)

Where X' is the sample mean, σ is the sample standard deviation, n is the sample size, and Z is the critical value for a 90% confidence interval.

Since the sample size is 12, we need to use a t-distribution with 11 degrees of freedom to find the critical value, because we are estimating the population standard deviation from the sample. Using a t-distribution table or calculator, we can find that the critical value for a 90% confidence interval with 11 degrees of freedom is approximately 1.796.

Substituting the values into the formula, we get:

CI = 7.2 ± 1.796*(1.2/√12)

= 7.2 ± 0.81

Therefore, the 90% confidence interval for the mean pressure is:

(7.2 - 0.81, 7.2 + 0.81) or (6.39, 7.99)

So, we can say with 90% confidence that the true mean pressure of the machine lies between 6.39 thousand psi and 7.99 thousand psi.

After answering the presented question, we can conclude that Therefore, the interest paid would be $1504.

In mathematics, interest is the amount of money earned or payable on an original investment or loan. You can use either simple or compound interest. Simple interest is calculated as a percentage of the initial amount, whereas compound interest is calculated on the principal amount plus any previously earned interest. If you invest $100 at a 5% annual simple interest rate, you will get $5 in interest every year for three years, for a total of $15.

To calculate the amount of interest paid on a simple interest loan, we use the following formula:

Interest = Principal x Rate x Time

where:

Principal is the amount borrowed

Rate is the annual interest rate as a decimal

Time is the length of the loan in years

In this case, we have:

Principal = $4700

Rate = 0.08 (8% expressed as a decimal)

Time = 4 years

So, the interest paid on this loan would be:

Interest = $4700 x 0.08 x 4

Interest = $1504

Therefore, the amount of interest paid would be $1504.

the final velocity is approximately 14.5 meters per second.

The rate at which an object's velocity alters over time is known as acceleration. It is a vector quantity, which means it has both magnitude (a numerical value) and direction.

Using the formula: v² = u2 + 2as

We can plug in the values given:

u = 6 m/s (initial velocity)

a = 3 m/s² (acceleration)

s = 29 m (distance)

v² = (6 m/s)² + 2(3 m/s²)(29 m)

v² = 36 m²/s² + 174 m²/s²

v²= 210 m²/s²

To solve for v, we need to take the square root of both sides of the equation:

v = √(210 m²/s²)

v ≈ 14.5 m/s (rounded to one decimal place)

A triangle is a closed geometric shape that has three sides, three angles, and three vertices (or corners). It is one of the most basic and important shapes in geometry. The sum of the angles in a triangle is always 180 degrees, and the length of each side can be calculated using the Pythagorean theorem or other geometric formulas. Triangles can be classified into different types based on the length of their sides and the size of their angles, such as equilateral, isosceles, scalene, acute, obtuse, and right triangles. Triangles are used extensively in mathematics, science, engineering, and many other fields.

To find the measure of angle P, we can use the Pythagorean theorem and trigonometric functions. Here's the step-by-step solution:

From the given information, we know that one angle of the triangle is 90 degrees, and the lengths of the adjacent sides are 5 and 13.

Using the Pythagorean theorem, we can find the length of the hypotenuse:

c^2 = a^2 + b^2

c^2 = 5^2 + 13^2

c^2 = 194

c = sqrt(194)

c ≈ 13.93

So the length of the hypotenuse is approximately 13.93 units.

Now, we can use the trigonometric function sine to find the measure of angle P:

[tex]sin(P) = opposite / hypotenuse[/tex]

If he agrees to pay back the loan in 8 yearly payments at 14% p.a. compound interest. The amount of each yearly payment is  K 368.51.

To calculate the amount of each yearly payment, we can use the formula for the present value of an annuity:

PV = A * [(1 - (1 + r)^-n) / r]

where:

PV = present value of the loan

A = annual payment

r = interest rate per year

n = number of years of the annuity

In this case, Mr. Apo Man borrowed K 2 000 from the bank at an interest rate of 14% p.a. compound interest, and agreed to pay back the loan in 8 yearly payments.

So, we have:

r = 14% = 0.14

n = 8

PV = K 2 000

We can solve for A by rearranging the formula:

A = PV * r / [(1 - (1 + r)^-n)]

Substituting the values, we get:

A = K 2 000 * 0.14 / [(1 - (1 + 0.14)^-8)]

A = K 2 000 * 0.14 / 0.7598

A = K 368.51

Therefore, the amount of each yearly payment that Mr. Apo Man needs to make to repay the loan in 8 years at 14% p.a. compound interest is K 368.51.

What Does a Triangle's Area Mean?

The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h. So, we need to know the triangular polygon's base (b) and height (h) in order to calculate its area. Any triangle kinds, including scalene, isosceles, and equilateral, can use it. It should be observed that the triangle's base and height are parallel to one another. Square units are used to measure the area unit (m2, cm2).

Let’s call the height of the triangle “h” and the base “b”. We know that the area of the triangle is 450 square feet. We also know that the base is 4 times the height. So we can write:

b = 4h

We can use this information to write an equation for the area of the triangle:

(1/2)b×h = 450

Substituting b = 4h, we get:

(1/2)(4h)(h) = 450

Simplifying this equation gives us:

2h²= 450

Dividing both sides by 2 gives us:

h² = 225

Taking the square root of both sides gives us:

h = 15

So the height of the triangle is 15 feet. We can use this to find the base:

b = 4h = 4(15) = 60

So the base of the triangle is 60 feet.

Answer:

the width of the rectangle is 11 cm, the length is 13 cm, and the area is 143 cm^2.

Step-by-step explanation:

Let's assume that the width of the rectangle is "x" cm.

According to the problem, the length of the rectangle is 2 more than its width, which means:

Length = x + 2

The formula for the perimeter of a rectangle is:

Perimeter = 2(length + width)

Substituting the given values, we get:

48 = 2(x + 2 + x)

48 = 2(2x + 2)

48 = 4x + 4

44 = 4x

x = 11

So, the width of the rectangle is 11 cm and the length is:

Length = 11 + 2 = 13 cm

The formula for the area of a rectangle is:

Area = length x width

Substituting the given values, we get:

Area = 11 x 13 = 143 cm^2

Therefore, the width of the rectangle is 11 cm, the length is 13 cm, and the area is 143 cm^2.

Answer:

Step-by-step explanation:

Length of rectangle is 2 more than its Width.

Let width be x and length be x +2.

If Perimeter is 48 cm .

=> 48 = 2(x + 2 + x)

=> 48 = 4x + 4

=> 48 - 4 = 4x

=> 44 = 4x

=> x = 44/4

=> x = 11 cm

Hence,

Length of rectangle = x +2 = 13 cm

Breadth of rectangle = 11 cm

Step-by-step explanation:

We are given the vectors:

u = 4i - j

v = -3i + 2j

To find 2u - 4v, we need to double u and subtract four times v:

2u = 2(4i - j) = 8i - 2j

4v = 4(-3i + 2j) = -12i + 8j

So, 2u - 4v = (8i - 2j) - (-12i + 8j) = 20i - 10j.

Therefore, 2u - 4v = 20i - 10j.

Step-by-step explanation:

This equation is already factored into 3 terms.

For this expression to equal 0, any of the terms must be equal to 0. Set each factor equal to 0 and solve for x.

x^2 = 0

x = 0

4x - 3 = 0

4x = 3

x = 3/4

5x - 1 = 0

5x = 1

x = 1/5

The solutions are x = 0, 3/4, 1/5

Using the fact that the triangles are similar, we can see that x = 5.

We can see that the two triangles are similar, because both of them are right triangles and both have the same angle at the vertices S and P.

Then there is a constant of proportionality between all the sides, let's say that the constant of proportionality is k, then we can write two equations:

5k = 15

3k = x + 4

Solving the first equation we get:

k = 15/5 = 3

In mathematics, an inequality is a statement that compares two values or expressions and shows the relationship between them, usually using the symbols > (greater than), < (less than), ≥ (greater than or equal to), or ≤ (less than or equal to).

For example, "3 > 2" is an inequality that states that 3 is greater than 2. Similarly, "x ≤ 5" is an inequality that states that the value of x is less than or equal to 5.

Inequalities are used to represent ranges of possible values and are commonly used in algebra, calculus, and other branches of mathematics. They are often used to describe constraints in optimization problems, such as finding the maximum or minimum of a function subject to certain conditions.

To begin, we must convert the weights to the same units. We can convert rabbit weight to grammes as follows:

300 grammes = 0.3 kilos

We can also convert duck weight to grammes:

700 grammes = 0.7 kilos

We can now multiply the weights of rabbits and ducks:

300 grammes plus 700 grammes equals 1000 grammes

300 grammes plus 1300 grammes plus 700 grammes equals 2300 grammes.

To calculate how many more grammes of pellets Al feeds the chickens than the rabbits and ducks combined, subtract the total weight of pellets fed to the rabbits and ducks from the weight of pellets fed to the chickens:
