The circle below is centered at the origin and has a radius of 8. What is its
equation?

The number of monthly payments required to pay off the loan of $128,000 at 4% interest is 232.48 which is equivalent to approximately 232 payments.

To determine the number of monthly payments required to pay off a loan, you can use the formula for loan amortization: n = (-log(1 - B/A * r)) / log(1 + r)

Where: n = number of monthly payments, A = loan amount ($128,000), B = monthly payment ($611.09), r = monthly interest rate (4% / 12 months = 0.0033)

The number of monthly payments for the loan is plugged and computed as:

n = (-log(1 - $128,000/$611.09 * 0.0033)) / log(1 + 0.0033)

n = (-log(1 - 0.0208)) / log(1.0033)

n = (-log(0.9792)) / log(1.0033)

n = 21.8068 / 0.093984

n = 232.48 payment.

Answer: The result when the number 45 is increased by 57% is approximately 70.65.

Step-by-step explanation:

To find the result when the number 45 is increased by 57%, we need to calculate 45 * (1 + 0.57), where 0.57 represents 57% as a decimal.

Performing the calculation, we get:

45 * (1 + 0.57) = 45 * 1.57 = 70.65

So, the result when the number 45 is increased by 57% is approximately 70.65.

Answer:

70.65

Step-by-step explanation:

The new value =

45 + The value of the percentage increase =

45 + (57% × 45) =

45 + 57% × 45 =

(1 + 57%) × 45 =

(100% + 57%) × 45 =

157% × 45 =

157 ÷ 100 × 45 =

157 × 45 ÷ 100 =

7,065 ÷ 100 =

To find the echelon form of the given augmented matrix with 1's on the diagonal, we perform row operations to eliminate the entries below the diagonal. The goal is to get the matrix in row echelon form. Here are the steps:

Step 1: Subtract the first row from the second and third rows to eliminate the 1's in the first column below the diagonal:

1 -1 2 400

0 1 -2 500

0 -2 5 -700

Step 2: Add twice the second row to the third row to eliminate the -2 below the diagonal:

1 -1 2 400

0 1 -2 500

0 0 1 300

Step 3: Add 2 times the third row to the first row and add 2 times the third row to the second row to eliminate the entries above the diagonal:

a. The number of pizzas the pizzeria must sell today for employees to receive the bonus will be 78 pizza.

b. The percent decrease in the number of pizzas sold today compared to yesterday is 7.69%.

a) To determine the number of pizzas the pizzeria must sell today for employees to receive the bonus, we need to calculate 20% of the 65 pizzas sold yesterday. 20% of 65 pizzas is 0.20 * 65 = 13. So, the pizzeria must sell 65 + 13 = 78 pizzas today for employees to receive the bonus.

b) To calculate the percent increase or decrease in the number of pizzas sold today compared to yesterday, we need to divide the difference between the two days' sales by the number of pizzas sold yesterday and multiply by 100.

For the information provided, the total kinetic energy of both gliders after collision is 13.5 J. In an elastic collision, both momentum and kinetic energy are conserved.

The momentum conservation principle states that the total momentum of the system before the collision is equal to the total momentum after the collision. Mathematically, we can write this as:

m₁v₁i + m₂v₂i = m₁v₁f + m₂v₂f

where m₁ and v₁i are the mass and initial velocity of glider 1, m₂ and v₂i are the mass and initial velocity of glider 2, and v₁f and v₂f are their velocities after the collision.

Using this equation and the given values, we can solve for the final velocities:

(7.0 kg)(2.0 m/s) + (4.0 kg)(-5.0 m/s) = (7.0 kg)v₁f + (4.0 kg)v₂f

14.0 kg·m/s - 20.0 kg·m/s = 7.0 kg·v₁f + 4.0 kg·v₂f

-6.0 kg·m/s = 7.0 kg·v₁f + 4.0 kg·v₂f ---(1)

The kinetic energy of an object is given by the equation:

KE = 1/2 mv²

Therefore, the total kinetic energy of both gliders after the collision can be calculated as:

KE_total = 1/2 m₁ v₁f² + 1/2 m₂ v₂f²

Substituting the values of m₁, m₂, v₁f, and v₂f from equation (1) into this equation, we get:

KE_total = 1/2 (7.0 kg) (0.86 m/s²) + 1/2 (4.0 kg) (5.14 m/s²)

KE_total = 13.5 J

Step-by-step explanation:

The value of x is 12. The solution has been obtained by using trigonometry.

What is trigonometry?

The primary objective of the branch of mathematics known as "trigonometry" is the study of the sides, angles, and connections of the right-angle triangle. The angles of 0, 30, 45, 60, and 90 degrees are the most typical trigonometric angles to be utilised in computations.

We are given a right - angled triangle with one angle equal to 24° and the length of the base is 11.

Using trigonometry,

We know that cos theta = adjacent side/hypotenuse

So,

⇒cos θ = 11/x

Here, θ = 24°

So,

⇒cos 24° = 11/x

⇒x = 11/cos 24°

⇒x ≈ 12.04

⇒x ≈ 12

It is important to understand the concept of interest beacause it is a part of our life and it hels us to understand the economic situation of ourselves.

It is the interest calculated on the principal at a given rate for a time period.

We have.

There are two types of interest commonly studied.

1)

Simple interest

2)

Compound interest

Now,

Simple interest is the interest calculated only on the principal year after year.

Whereas compound interest is the interest calculated on the principal as well as the interest after the first year.

Example:

Principal = $100

Rate = 10%

Time = 2 years

Simple interest after two years.

= 2 x (10% of 100)

= 2 x (1/10 x 100)

= 2 x 10

= $20

Compound interest after two years.

Ist year:

=  (10% of 100)

= (1/10 x 100)

= $10

2nd year:

= 10% of (100 + 10)

= 1/10 x 110

= $11

So,

= 10 + 11

= $21

Answer:

Step-by-step explanation:

Calculate the total hours used: We add up the hours used each year to find the total hours used:

2,800 + 1,400 + 1,500 + 2,500 + 2,300 + 2,000 = 12,500

Calculate the total depreciation: We subtract the residual value from the cost to find the total depreciation:

$219,000 - $19,500 = $199,500

Calculate the annual depreciation expense: We divide the total depreciation by the number of years to find the annual depreciation expense:

$199,500 / 6 = $33,250

Calculate the depreciation expense per hour: We divide the annual depreciation expense by the estimated total hours to find the depreciation expense per hour:

$33,250 / 12,500 = $2.66

So the depreciation expense per hour is $2.66.

Calculate the depreciation expense for each year: We multiply the hours used each year by the depreciation expense per hour to find the depreciation expense for each year:

Year 1: 2,800 * $2.66 = $7,448

Year 2: 1,400 * $2.66 = $3,724

Year 3: 1,500 * $2.66 = $3,990

Year 4: 2,500 * $2.66 = $6,650

Year 5: 2,300 * $2.66 = $6,118

Year 6: 2,000 * $2.66 = $5,320

So the depreciation expense for each year is:

Year 1: $7,448

Year 2: $3,724

Year 3: $3,990

Year 4: $6,650

Year 5: $6,118

Year 6: $5,320

Approximately 2.51 x 10¹² joules of energy is released by a magnitude 5 earthquake.

A logarithmic equation is an equation that involves a logarithmic function. A logarithmic function is the inverse of an exponential function, and it represents the exponent to which a given base must be raised to obtain a given number.

The formula that relates the energy released by an earthquake to its magnitude is given by:

logE = 5.24 + 1.44M

To find the amount of energy released by a magnitude 5 earthquake, we can substitute M = 5 into the formula and solve for E.

logE = 5.24 + 1.44(5)

logE = 5.24 + 7.2

logE = 12.44

Now we need to convert this logarithmic value to a regular value of E. We can do this by taking the antilogarithm (or exponentiating) both sides of the equation.

10⁽ˡᵒᵍᴱ⁾ = 10⁽¹²ॱ⁴⁴⁾

E = 2.51 x 10¹² joules

Therefore, approximately 2.51 x 10¹² joules of energy is released by a magnitude 5 earthquake.
