The values of the given expressions are,

(a) (f + g)(-1) = 12

(b) (f + g)(-1) = -4

(c) fg(-1) = 32

(d) (f/g)(-1) = 1/2

The given functions are,

f(x) = x²  - 3x

g(x) = x + 9

(a) Now to find (f + g)(-1)

Add the functions

⇒ (f + g)(x) = (x²  - 3x) + (x + 9)

                 =  x²  - 2x + 9

Now put x = -1

⇒ (f + g)(-1) =  (-1)²  - 2(-1) + 9

                  = 1 + 2 + 9

                   = 12

(b) Now to find (f - g)(-1)

Subtract the functions

⇒ (f - g)(x) = (x²  - 3x) - (x + 9)

                 =  x²  - 4x - 9

Now put x = -1

⇒ (f - g)(-1) =  (-1)²  - 4(-1) - 9

                  = 1 + 4 - 9

                   = -4

(c) To find fg(-1)

To find this multiply the functions we get,

⇒ fg(x) = (x²  - 3x)(x + 9)

           = x³ - 3x² + 9x² - 27x

           = x³ + 6x² - 27x

Now put x = -1

⇒ fg(-1) = (-1)³ + 6(-1)² - 27(-1)

            = -1 + 6 + 27

            = 32

(d) To find (f/g)(-1)

Divide the functions we get,

⇒ (f/g)(x) = (x²  - 3x)/(x + 9)

Now Put x = -1  we get,

⇒ (f/g)(-1) = ((-1)²  - 3(-1))/(-1 + 9)

               = 4/8

The quadratic equation is f(x) = (x + 9)² + 37, and  the numerical values of h and k are h = - 9 and k = 37, respectively

The function is given as:

f(x) = x² + bx + 118

Start by differentiating the function,

f'(x) = 2x + b

Set to 0

2x + b = 0

Solve for x

x = -b/2

Substitute x = -b/2 in f(x) = x² + bx + 118

f(-b/2) = (-b/2)² + b(-b/2) + 118

This gives

f(-b/2) = b²/4 - b²/2 + 118

Evaluate

f(-b/2) = - b²/4 + 118

Since, The minimum of the function is 37.

So, we have:

- b²/4 + 118 = 37

Subtract 118 from both sides

- b²/4 = - 81

Multiply both sides by -4

b² = 324

Take the square root of both sides

b = 18

Substitute b = 18 in f(x) = x² + bx + 164

f(x) = x² + 18x + 118

Rewrite as:

f(x) = (x² + 18x) + 118

This gives

f(x) = (x² + 18x + (18/2)² - (18/2)²) + 118

Rewrite as:

f(x) = (x² + 18x + 9²) - 9² + 118

f(x) = (x² + 18x + 9²) + 37

Express as a perfect square expression

f(x) = (x + 9)² + 37

Thus, The function is represented as:

f(x) = (x - h)² + k

By comparison, we have:

h = - 9 and k = 37

Hence, the numerical values of h and k are h = - 9 and k = 37, respectively

The total interest for the loan is $4,550. This means that over the course of 5 years, you will pay back the original loan amount of $13,000 plus $4,550 in interest for a total of $17,550.

To calculate the total interest for this loan, we need to use the simple interest formula:
Monthly EMI formula :
Interest = Principal x Rate x Time

In this case, the principal (amount borrowed) is $13,000, the rate is 7%, and the time is 5 years.

So,

Interest = $13,000 x 0.07 x 5

Interest = $4,550

It's important to keep in mind that this calculation assumes that the interest rate remains constant over the entire 5-year period.

The probability that you select a Jack given that it is a Club P(Jack|Club):

There are 4 Jacks in a deck (one for each suit), and since we are given that the selected card is a Club, we only need to consider the 13 cards in the Club suit.

So, the number of favorable outcomes is 1 (the Jack of Clubs), and the total number of possible outcomes is 13 (the number of cards in the Club suit)

P(Jack|Club) = 1 / 13

The probability that you select a Club given that it is a Jack

Option b. 0.48 would be the closest representation for the logarithm value of log10 3 among the given options.

To determine the value of log10 3 among the given options, we need to understand that the logarithm of a number represents the exponent to which the base must be raised to obtain that number. In this case, we are looking for the logarithm of 3 with base 10.

Among the given options (0.30, 0.48, 1.10, 2.10), none of them exactly represents the value of log10 3. However, we can make an estimation based on the given options.

The value of log10 3 is approximately 0.48. This can be inferred from the fact that log10 1 is 0 and log10 10 is 1, so the logarithm of numbers between 1 and 10 should be between 0 and 1. Since 3 is closer to 1 than 10, we can estimate its logarithm to be closer to 0.48 than 1.10 or 2.10.

Yes, it is possible to find whole Number .In general, if we let n be any whole number from 1 to 14, we will get a corresponding whole number value for m that satisfies the equation.

values of m and n that fit the equation 3m+6n=87. First, we can simplify the equation by factoring out 3 to get 3(m+2n)=87. Then, we can divide both sides by 3 to get m+2n=29.

Since we want whole number values for m and n, we can try different values of n and see if we get a whole number value for m.

For example, if we let n=1, then m+2=29, so m=27. This gives us one possible solution of m=27 and n=1.

For the quadratic equation [tex]\boxed{ax^2 + bx + c = 0}[/tex] to have exactly one real root, the value of its discriminant, [tex]\boxed{b^2 - 4ac}[/tex], must be zero.

For the given equation:

• c = 10.

Substituting these values into the formula for discriminant, we get:

Step-by-step explanation:

To find the next digit in the quotient using the standard algorithm, you follow these steps:

First, divide the largest possible multiple of the divisor (13) into the dividend (543) without exceeding it. In this case, 13 goes into 54 four times (4 × 13 = 52).

Subtract the product obtained in step 1 (52) from the dividend (543), resulting in a remainder of 543 - 52 = 491.

Bring down the next digit of the dividend (3) next to the remainder (491), creating the new number 4913.

Repeat step 1 by dividing the largest possible multiple of the divisor (13) into the new number (4913) without exceeding it. The largest multiple of 13 that fits into 491 is 37 (37 × 13 = 481).

Subtract the product obtained in step 4 (481) from the new number (4913), resulting in a remainder of 4913 - 481 = 4432.

At this point, you have obtained the next digit in the quotient. It is the result of dividing the new number (4432) by the divisor (13).

This can be calculated using the combination formula (nCr).

In this case, it is 13C5.

Number of possibilities for selecting 1 gold Mega Ball out of 12 is simply 12.

Therefore, the total number of possible outcomes is (13C5) × 12.

To calculate (13C5), we can use the combination formula: nCr = n! / (r! (n - r)!)

(13C5) = 13! / (5! × (13 - 5)!)
