Use cramer's rule to solve this system: 8x+5y= 2x - 4y = - 10

An equation of the line in slope-intercept form that is perpendicular to line g and passes through the point (1, −2) is y = 3x - 5.

Here, we have,

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

m represent the slope.

x and y represent the points.

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (5 - 6)/(0 + 3)

Slope (m) = -1/3.

For the equation of line g, we have:

y - 6 = (x + 3)

y - 6 = -1/3(x + 3)

y = -x/3 + 1 + 6

y = -x/3 + 7

Therefore, the slope, m = -1/3.

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

-1/3 × m₂ = -1

m₂ = 3

At data point (1, -2), an equation of this line can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

y - (-2) = 3(x - 1)

y + 2 = 3x - 3

y = 3x - 5

The marginal cost for the fifth unit is $50. Hence, the correct option is b. $50.

To find the marginal cost for the fifth unit, we need to calculate the change in total cost when moving from producing 4 units to producing 5 units.

Total cost consists of both fixed costs and variable costs. The fixed costs remain constant regardless of the number of units produced, so they do not contribute to the marginal cost.

Variable costs, on the other hand, increase as more units are produced. The change in variable costs from producing 4 units to producing 5 units is $150 - $100 = $50.

Therefore, the marginal cost for the fifth unit is $50.

The distance from the house that should place the base of the ladder is approximately 5.95 feet.

We can start by modeling the situation as a right triangle. Doing this will allow us to use basic trigonometric functions to determine how far the base of the ladder should be placed from the house. Imagine the house makes a 90 degree angle with the ground. The ladder gets propped against the house, making a 75 degree angle with the ground. We can use the fact that cos(75°) = base distance/length of ladder to figure out the length of the base. Multiplying both sides by length of ladder we get, length of ladder × cos(75°) = base distance. Now, by plugging in the length of the ladder we find that base distance = 5 2381/2500 or roughly 5.95 feet.

here r = PQ, p = QR = 7.6 , q = PR = 8.4 and ∠ R = 62° , then

r² = 7.6² + 8.4² - (2 × 7.6 × 8.4 × cos62° )

[tex]3x-2+\frac{5}{x}[/tex]

Step-by-step explanation:

To divide the polynomial (9x^3 - 6x^2 + 15x) by the monomial 3x^2, we can write it as:

(9x^3 - 6x^2 + 15x) ÷ (3x^2)

To simplify the division, we divide each term of the polynomial by 3x^2:

(9x^3 ÷ 3x^2) - (6x^2 ÷ 3x^2) + (15x ÷ 3x^2)

To divide monomials with the same base, we subtract the exponents. So:

9x^3 ÷ 3x^2 = 9/3 * (x^3/x^2) = 3x^(3-2) = 3x

(-6x^2) ÷ (3x^2) = -6/3 * (x^2/x^2) = -2

15x ÷ 3x^2 = 15/3 * (x/x^2) = 5/x

Putting it all together, we have:

(9x^3 - 6x^2 + 15x) ÷ (3x^2) = 3x - 2 + 5/x

Therefore, the division of (9x^3 - 6x^2 + 15x) by 3x^2 is 3x - 2 + 5/x.

The relative change in average television sizes is 5.94%.

To calculate the absolute change in average television sizes, we subtract the initial average size from the final average size:

Absolute change = 42.8 inches - 40.4 inches

Absolute change = 2.4 inches

Therefore, the absolute change in average television sizes from the time of Joseph's deployment to the time he returned is 2.4 inches.

To calculate the relative change in average television sizes, we divide the absolute change by the initial average size and then multiply by 100 to express it as a percentage:

Relative change = (Absolute change / Initial average size) × 100

Given statement solution is :- "3 and 5 - 1," the mean is 3.5, the median is 5, and there is no mode.

To find the mean, median, and mode for the given numbers, let's start by organizing the numbers in ascending order:

For "3 and 5":

Ascending order: 3, 5

Mean:

To find the mean, we sum up all the numbers and divide the total by the count of numbers.

Mean = (3 + 5) / 2 = 8 / 2 = 4

Median:

The median is the middle value in a set of numbers when they are arranged in ascending order. Since we have two numbers, the median is the average of the two middle numbers.

Median = (3 + 5) / 2 = 8 / 2 = 4

Mode:

The mode is the value that appears most frequently in a set of numbers.

In this case, there is no repeating value, so there is no mode.

For "3 and 5 - 1":

Ascending order: 2, 5

Mean:

Mean = (2 + 5) / 2 = 7 / 2 = 3.5

Median:

Median = 5 (since we have two numbers, the median is the average of the two middle numbers, which is 5 in this case)

Mode:

Again, there is no repeating value, so there is no mode.

Therefore, for "3 and 5," the mean and median are both 4, and there is no mode.

To calculate the monthly payment for a 15-year term mortgage, we need to consider the purchase price, down payment, and the interest rate associated with the FICO score range.

Given information:

Purchase price: $181,700.00

Down payment (20%): $181,700.00 * 0.20 = $36,340.00

FICO score: 760

Loan amount: Purchase price - Down payment = $181,700.00 - $36,340.00 = $145,360.00

Step-by-step explanation:

The  mean is 5.907, and the standard deviation is 0.677.

To construct a binomial probability distribution, we need the parameters n and p, where n is the number of trials and p is the probability of success in each trial.

From the provided data, it appears that we have the probability distribution for a binomial random variable X with n = 6 trials. The probabilities are as follows:

P(0) = 0.0156

P(1) = 0.0938

P(2) = 0.2344

P(3) = 0.3125

P(4) = 0.2344

P(5) = 0.0938

P(6) = 0.0156

The sum of these probabilities should be equal to 1.

Now, let's compute the mean (μ) and standard deviation (σ) using the formulas:

μ = np

σ = √(np(1 - p))

So, p = P(success)

= P(1) + P(2) + P(3) + P(4) + P(5) + P(6)

= 0.0938 + 0.2344 + 0.3125 + 0.2344 + 0.0938 + 0.0156

= 0.9845

Now, we can calculate the mean and standard deviation:

μ = np = 6 x 0.9845 ≈ 5.907

σ = √(np(1 - p))

= √(6 x 0.9845 x (1 - 0.9845))

= 0.677

Therefore, the mean is 5.907, and the standard deviation is 0.677.

Answer:

Brenda will be able to afford the $20,000 car after 10 years.

Step-by-step explanation:

To determine whether Brenda will be able to afford a $20,000 car after 10 years, we need to calculate the future value of her investment with an interest rate of 4.5%.

The formula for calculating the future value of an investment is:

FV = PV * (1 + r)^n

Where:

FV = Future Value

PV = Present Value (initial investment)

r = Interest rate

n = Number of periods

In this case, Brenda's initial investment (PV) is $15,000, the interest rate (r) is 4.5% (or 0.045 as a decimal), and the number of periods (n) is 10 years.

Let's calculate the future value of Brenda's investment:

FV = $15,000 * (1 + 0.045)^10

FV = $15,000 * (1.045)^10

FV ≈ $22,292.26

After 10 years, Brenda's investment will grow to approximately $22,292.26.

Since the future value of her investment is greater than the cost of the car ($20,000), Brenda will be able to afford the $20,000 car after 10 years.

Answer:

To calculate the future value of an investment compounded annually, we can use the formula:

Future Value = Principal Amount * (1 + Interest Rate)^(Number of Periods)

In this case, the principal amount is $3200, the interest rate is 2.4% (or 0.024), and the investment is compounded annually for 4 years.

Plugging these values into the formula, we get:

Future Value = $3200 * (1 + 0.024)^4

Calculating the exponent first:

(1 + 0.024)^4 = 1.024^4 = 1.09985925696

Multiplying the principal amount by the exponent:

Future Value = $3200 * 1.09985925696

Future Value ≈ $3,519.47

Therefore, the investment will be worth approximately $3,519.47 after 4 years when compounded annually at a rate of 2.4%.

Step-by-step explanation:

The polynomial in standard form is - x⁶ -2x⁴ + 5x - 4 = 0.

The polynomial expression you provided is indeed valid, and we can write it in standard form by rearranging the terms:

f(x) = f(x) - 2x⁴ - x⁶ - 4 + 5x

f(x) - f(x) = -x⁶ - 2x⁴ + 5x - 4

The term "f(x)" appears on both sides of the equation, so we can subtract it from both sides:

0 = - x⁶ -2x⁴ + 5x - 4

Now, we have the polynomial equation in standard form:

- x⁶ -2x⁴ + 5x - 4 = 0

In this form, the polynomial is written with the terms arranged in descending order of the exponents (from highest to lowest), and the constant term is on the right side of the equation.
