Answers

Answer 1

Answer:

$320

------------------

what is 8.75 as a fraction?

Answers

The number 8.75 is equivalent to the fraction 35/4 in its simplest form.

To convert 8.75 to a fraction, we can write it as a fraction with a denominator of 1. We then multiply both the numerator and denominator by 100 to get rid of the decimal point. This gives us:

8.75 = 8.75/1

= 875/100

Next, we want to get rid of the decimal point, which we can do by multiplying both the numerator and denominator by a power of 10 that moves the decimal point of the numerator to the right until it disappears. In this case, we can multiply both the numerator and denominator by 100, which gives us:

8.75/1 x 100/100 = 875/100

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 25. This gives us:

875/100 = (875/25) / (100/25) = 35/4

Therefore, we conclude that 8.75 is equivalent to the fraction 35/4 in its simplest form.

How to solve this first order linear differential equation?

Answers

To find first-order linear differential equations solution, we have to derive the general form or representation of the solution.

With the help of the steps shown below, we can learn how to solve the first-order differential equation.

1. Reorder the terms in the given equation so that they have the form [tex]$\frac{dy}{dx}+Py=Q[/tex] where P and Q are constants or functions of the independent variable x only.

2. Integrate P (obtained in step 1) with respect to x and then put this integral as a power of e to determine the integrating factor.

[tex]$e^{\int P d x}[/tex] = IF

3. The linear first-order differential equation's two sides should be multiplied by the IF.

4. The L.H.S of the equation is always a derivative of [tex]$y \times M(x)$[/tex] i.e. L.H.S [tex]$= \frac{d(y \times I . F)}{dx}[/tex]

[tex]$d(y \times I . F) d x=Q \times I . F$[/tex]

5. In order to arrive at the solution, we simply integrate both sides with respect to x in the last step.

Therefore [tex]y \times I . F=\int Q \times I . F d x+C$,[/tex]

where C is some arbitrary constant

Similarly, we can also solve the other form of linear first-order differential equation [tex]$\frac{dy}{dx}+Py=Q[/tex] using the same steps.

P and Q are y's functions in this manner. We determine the solution, which will be, by using the integrating factor (I.F), which is

[tex]$(x) \times(I . F)=\int Q \times I . F d y+c$[/tex]

Now, to get a better insight into the linear differential equation, let us try solving some questions. where C is some arbitrary constant.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given is that Limousine Company {P} charges a rental fee plus an additional charge per hour. The equation {y} = 50 + 30x shows the total cost. The cost to rent a limousine from Company {R} is shown below in the table as -

Time :   1       2        3         4       5

The circle x2 + y2 – 18x + 8y + 48 = 0 is translated one unit right and two units down. Which is the radius and center of the translated circle?

Answers

The radius and center of the translated circle are,

Radius = 7 units

Center = (10, - 2)

What is Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

The equation of circle is,

x² + y² - 18x + 8y + 48 = 0

Now, We can simplify the equation as;

x² + y² - 18x + 8y + 48 = 0

x² - 18x + 81 - 81 + y² + 8y + 16 - 16 + 48 = 0

(x - 9)² + (y + 4)² = 49

(x - 9)² + (y + 4)² = 7²

Hence, The radius of circle = 7

And, Center = (9, - 4)

Let the center of circle after translated one unit right and two units down is, (h', k')

Hence, We get;

h' = 9 + 1 = 10

k' = - 4 + 2 = - 2

Thus, The equation of the translated circle is,

(x - 10)² + (y - (- 2))² = 7

Hence, the radius and center of the translated circle are,

Radius = 7 units

Center = (10, - 2)

Marco's charges an additional fee for toppings, but all toppings cost the same. Kevin got pepperoni, banana peppers, and black olives on his pizza for a cost of $15.74. Brian ordered mushrooms and eggplant on his pizza and paid $14.49. Using this information, write an equation for the cost of a pizza, C, as a function of the toppings, t, ordered.

Answers

Answer: Let's use x to represent the cost of each topping. Then, the cost of a pizza with t toppings can be expressed as:

C = x * t + 15

We know that Kevin's pizza with 3 toppings cost $15.74, so we can write an equation using this information:

15.74 = 3x + 15

Solving for x, we get:

x = (15.74 - 15) / 3 = 0.74

So, each topping costs $0.74. Now we can use the information about Brian's pizza to check our answer:

14.49 = 2x + 15

Substituting x = 0.74, we get:

14.49 = 2 * 0.74 + 15

Which simplifies to:

14.49 = 1.48 + 15

This confirms that x = 0.74 is the correct cost for each topping. Therefore, the equation for the cost of a pizza as a function of the toppings ordered is:

C = 0.74t + 15

you lease a car vauled at 23495 for 3 years
at 429.95/month

Answers

The amount of interest paid over the 3-year lease is $4,643.64 for a car.

What is a monthly payment?

A monthly payment is a payment made every month to disburse loans or advances.

First, we need to calculate the total amount paid over the 3-year lease.

The monthly payment is $429.95, and there are 36 months in the lease, so:

Total lease payments = 36 x $429.95 = $15,478.20

The down payment of $500 is separate from the lease payments, so we don't include it in this calculation.

Next, we need to calculate the interest paid over the 3-year lease. We are told that interest is 30% of the monthly payment, so:

Monthly interest = 30% of $429.95 = $128.99

To find the total interest paid over the 3-year lease, we can simply multiply the monthly interest by the number of months in the lease:

Total interest paid = 36 x $128.99 = $4,643.64

Therefore, the amount of interest paid over the 3-year lease is $4,643.64.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² - 12x + 6 = 0   be equation (1)

Now , to calculate the solution of x ,

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = 12 ± √ ( 144 ) - ( 24 ) / 2
