The input is 8, the output of the function f(x) would be -5.

What is the function?

Function is a relationship or expression involving one or more variables.  It has a set of input and outputs.

Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given in 1837 by the German mathematician Peter Dirichlet

To find the output of the function f(x) when x is 8, we substitute x = 8 into the function and simplify:

f(x) = 8/x - 6

f(8) = 8/8 - 6

f(8) = 1 - 6

f(8) = -5

Hence, if the input is 8, the output of the function f(x) would be -5.

The expression can be simplified to: [tex]tan(x) + cot(x)/sec(x) = sin(x) * (1 / \sqrt(1 - sin^2(x)) + \sqrt(tan^2(x)) / \sqrt(1 - sin^2(x)))[/tex]

We can simplify the expression as follows:

tan(x) + cot(x)/sec(x) = tan(x) + 1/tan(x) / 1/cos(x) = tan(x) + cos(x) / tan(x) * cos(x) = tan(x) + cos^2(x) / tan(x)

Using the identity: tan(x)^2 + 1 = sec^2(x), we can simplify further:

tan(x) + cos^2(x) / tan(x) = tan(x) + cos^2(x) / (sqrt(sec^2(x) - 1)) = tan(x) + cos^2(x) / sqrt(tan^2(x) + 1 - 1) = tan(x) + cos^2(x) / sqrt(tan^2(x))

Using the identity sin^2(x) + cos^2(x) = 1, we can simplify further:

[tex]tan(x) + cos^2(x) / \sqrt(tan^2(x)) = tan(x) + (1 - sin^2(x)) / \sqrt(tan^2(x)) = tan(x) + \sqrt(1 - sin^2(x)) / \sqrt(tan^2(x)) = sin(x) * (1 / \sqrt(1 - sin^2(x)) + \sqrt(tan^2(x)) / \sqrt(1 - sin^2(x)))[/tex]

Therefore, the expression can be simplified to:

Answer:

a. The probability that a married couple watches the show can be calculated by multiplying the probabilities that each spouse watches the show:

P(Married couple watches the show) = P(Husband watches the show) * P(Wife watches the show) = 0.4 * 0.5 = 0.2

Step-by-step explanation:

b. The probability that a wife watches the show, given that her husband does, can be calculated using Bayes' theorem:

P(Wife watches the show | Husband watches the show) = P(Husband watches the show | Wife watches the show) * P(Wife watches the show) / P(Husband watches the show)

P(Wife watches the show | Husband watches the show) = 0.7 * 0.5 / 0.4 = 0.875

c. The probability that at least one member of a married couple will watch the show can be calculated as the sum of the probabilities that either the husband or the wife watches the show:

P(At least one member of a married couple watches the show) = P(Husband watches the show) + P(Wife watches the show) - P(Married couple watches the show) = 0.4 + 0.5 - 0.2 = 0.7

Answer:

Step-by-step explanation:

Yes, the ratios 4:6 and 2:3 are equivalent.

To see why, we can compare the proportions of the two ratios by dividing each term by the smaller term in each ratio.

In the ratio 4:6, if we divide both terms by 4, we get:

4/4 : 6/4 = 1 : 3/2

In the ratio 2:3, if we divide both terms by 2, we get:

2/2 : 3/2 = 1 : 3/2

Since both ratios reduce to the same proportion of 1 : 3/2, we can conclude that the ratios 4:6 and 2:3 are equivalent.

Ratios are mathematical expressions that compare two or more quantities. When two ratios are equivalent, it means that they represent the same proportion, even if the numbers in the ratios are different.

To compare the ratios 4:6 and 2:3, we divided each term in each ratio by the smallest term. This is because dividing each term by the same number will keep the proportion of the ratio the same.

For example, in the ratio 4:6, dividing both terms by 4 gave us the proportion of 1 : 3/2, which is the same as the proportion of 2:3 when divided by 2. This means that, even though the numbers in the two ratios are different, they represent the same proportion, and therefore the ratios are equivalent.

It's important to note that when comparing ratios, it's best to reduce the ratios to their simplest form so that the proportions are more easily compared.

The solution set for the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex] is (-4, -3) ∪ (-3, ∞).

What is inequality?

An inequality is a mathematical statement that describes a relationship between two values or expressions, where one is greater than, less than, or not equal to the other.

To solve the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex], we can use the concept of interval notation and test each interval to see if it satisfies the inequality. Here are the steps:

Find the critical points of the expression, which are the values that make the expression equal to zero. In this case, the critical points are -5, -4, and -3.

Use these critical points to divide the number line into four intervals: (-∞, -5), (-5, -4), (-4, -3), and (-3, ∞).

Test a value in each interval to see if the inequality is true or false. We can use the sign of the expression to determine this:

For x < -5, all three factors are negative, so the product is negative. Therefore, this interval does not satisfy the inequality.

For -5 < x < -4, the first factor is positive and the other two factors are negative. The product is therefore negative. This interval does not satisfy the inequality.

For -4 < x < -3, the first and third factors are positive and the second factor is negative. The product is therefore positive. This interval satisfies the inequality.

For x > -3, all three factors are positive, so the product is positive. Therefore, this interval satisfies the inequality.

Write the solution set using interval notation. We have found that the solution set is (-4, -3) union ( -3, ∞).

Therefore, the solution set for the inequality [tex]3(x+5)^3(x+4)^6(x+3)^3 > 0[/tex] is (-4, -3) ∪ (-3, ∞).

The federal loan at 2.8% is approximately 11000, and the private bank loan at 4.8 percent is around 39000 (which is 50000 - 11000).

Let's use f and p to denote the amounts of Josie's federal and private bank loans, respectively.

We know that the total amount of loans is 50000, so:

f + p = 50000

We also know that the interest on federal loans at 2.8% and the interest on private bank loans at 4.8% add up to 1600 per year. The interest on the federal loans is 0.028f and the interest on the private bank loans is 0.048p, so:

0.028f + 0.048p = 1600

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for p:

p = 50000 - f

Substituting this into the second equation, we get:

[tex]0.028f + 0.048(50000 - f) = 1600[/tex]

Simplifying and solving for [tex]f[/tex], we get:

[tex]f = \frac{1600 - 0.048 \cdot 50000}{0.02} \approx 11000[/tex]

Therefore, the federal loan at 2.8% is approximately 11000, and the private bank loan at 4.8% is approximately 39000 (which is 50000 - 11000).

Answer:

The solution to the equation 20 = m ÷ -5 is m = -100

To see this, we can multiply both sides of the equation by -5 to isolate the variable m:

20 × -5 = m ÷ -5 × -5

Expanding the right side of the equation:

20 × -5 = m × 1

Combining like terms:

-100 = m

And the solution is:

m = -100

Verification:

To verify the solution, we can plug in the value of m back into the original equation and see if it is true:

20 = -100 ÷ -5

Expanding -100 ÷ -5:

20 = 20

Since 20 = 20 is a true statement, we have verified that the solution m = -100 is correct.

If the ratio of the length to width of the rectangle is 3 to 2, we can write the length and width as:

length = 3x and width = 2x

where x is a common factor that can be determined once we know one of the dimensions.

Since the length of the rectangle is given as 1 3/4 feet, we can set x = 1 3/4:

length = 3x = 3 * 1 3/4 = 5 1/4 feet

width = 2x = 2 * 1 3/4 = 3 1/2 feet

Now that we know the length and width of the rectangle, we can calculate its area in square inches:

area = length * width = 5 1/4 * 3 1/2 = 18 3/8 square feet

To convert from square feet to square inches, we multiply by 12^2 = 144:

area = 18 3/8 * 144 = 2664 square inches

The side RT of the triangle is 13 m.

Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.

The sine law is a mathematical formula used in trigonometry to relate the sides and angles of a triangle. The sine law states that:

a/sin(A) = b/sin(B) = c/sin(C)

where:

a, b, and c are the lengths of the sides of the triangle

A, B, and C are the angles opposite those sides

Using sine law:

RT/sin 34° = ST/sin 109°

RT/sin 34° = 22/sin 109°

RT = (22 * sin 34°)/(sin 109°)

RT = 13 m
