Answer: To use synthetic division to find f(3), we will divide the polynomial 9v² - 28v + 19 by v - 3.
Here's the process:
| 9 -28 19|
v-3|____________|
9(3)² - 28(3) + 19
| 9 -84 57|
0 -96 38
So, f(3) = 9(3)² - 28(3) + 19 = 9(9) - 28(3) + 19 = 81 - 84 + 19 = -4 + 19 = 15.
So f(3) = 15.

2000 Paul was twice as old as his brother Biko. In 2008 Paul was only four years older than his brother. In what year was Biko born ? Select one: a. 1996 b. 1990 c. 1992 d. 1998 e. 2000
Answer:
a. 1996
Step-by-step explanation:
Let Paul's age in 2000 be P
Let Bilko's age in 2000 be B
Statement: Paul was twice as old as his brother Biko in 2000 means
P = 2B (1)
In 2008 Paul was only four years older than his brother.
Since 2008 is 8 years from 2000, both Paul and Bilko have aged 8 years
Paul's age in 2008 = P + 8
Bilko's age in 2008 = B + 8
Statement: In 2008 Paul was only four years older than his brother means
P + 8 = B + 8 - 4
P = B + 4 (2)
Given these two equations (1) and (2)
Substitute P = 2B from (1) in (2):
2B = B + 4
==> 2B - B = 4
==> B = 4
Therefore in 2000, Paul was 8 years old and Bilko was 4 years old
Bilko's year of birth = 2000 - 4 = 1996
Find f-1(x) and it’s domain.
For given function f(x) = √x + 9, the inverse function and domain are respectively, f⁻¹(x) = (y - 9)², x ≥ 0 & x ∈ (∞, ∞)
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Given that,
A function,
⇒ f(x) = √x + 9
f⁻¹(x) = ?
the given function is defined for all the values of x,
So domain of the function is real number,
x ∈ (∞, ∞)
Now for f⁻¹(x),
Suppose, f(x) = y
y = √x + 9
y - 9 = √x
squaring both the sides,
(y - 9)² = (√x)²
x = (y - 9)²
And value of x should be greater than zero

Answer:
rectangle: 30 ft²triangle: 12 ft²total: 42 ft²Step-by-step explanation:
You want the area of the composite figure consisting of a rectangle and a triangle.
RectangleThe area of the rectangle is ...
A = LW
A = (5 ft)(6 ft) = 30 ft² . . . . rectangle area
TriangleThe base of the triangle is the difference in length of the horizontal segments:
b = 9 ft -5 ft = 4 ft
The area is given by the formula ...
A = 1/2bh
A = 1/2(4 ft)(6 ft) = 12 ft² . . . . triangle area
Total areaThe area of the figure is the sum of the areas of its parts:
total area = rectangle area + triangle area
total area = 30 ft² +12 ft²
total area = 42 ft²
__
Additional comment
The area of this trapezoid can also be found using the trapezoid formula:
A = 1/2(b1 +b2)h
A = 1/2(9 ft +5 ft)(6 ft) = 42 ft²
The rectangle is shown in the figure as 5 ft wide and 6 ft tall. It does not matter which of these dimensions you call the length and which you call the width. Their product is the same either way.

Answer:
The $30,000 in revenue should be entered as a credit in the journal entry.
Step-by-step explanation:
In accounting, revenues are recorded as credits, which means that they increase the credit side of the accounting equation (revenues increase equity, which is a credit account). Debits, on the other hand, are used to record expenses and decreases in assets.Therefore, the journal entry to record $30,000 in revenue for the business on October 1 would be:Date
Account Account Number Debit Credit
1 - Oct Revenue 4050 30,000Since revenue is being credited, there is no debit amount entered in this entry. The credit amount of $30,000 is entered in the credit column, as shown above.
55 hours in one week with $15 per hour. What’s gross pay, assuming overtime is time and a half?
Answer:
Step-by-step explanation:
If you work 55 hours in one week and earn $15 per hour, your gross pay before taking into account any overtime can be calculated as follows:
Gross pay = 55 hours x $15/hour = $825
If you work overtime, which is time and a half, the additional pay can be calculated as follows:
Overtime pay = ($15/hour x 1.5) x (55 hours - 40 hours) = ($22.50/hour x 15 hours) = $337.50
So, the total gross pay including the overtime pay is:
Gross pay = $825 + $337.50 = $1,162.50
Therefore, the total gross pay for working 55 hours in one week at $15 per hour, with overtime pay calculated as time and a half, is $1,162.50.

Answer:
5/1/6+ 1/X + 1
Answer:
(1/x)+31
Step-by-step explanation:
To simplify the expression
5/(1/6) + 1/X + 1,
we need to first simplify the fraction 5/(1/6):
5/(1/6) = 5 * 6/1 = 30
Now we can substitute this value back into the expression:
30 + 1/X + 1
To combine the last two terms, we need to find a common denominator, which is X:
30X/X + 1/X + X/X
Simplifying the numerator:
30X + 1 + X
Combining like terms:31X + 1
so the simplified rational expression is (1/x)+31
A swimming pool has 500 gallons in it and is leaking. The change in the amount of water in the pool is -3 gallons per hour. How many gallons would the pool contain after 6 hours?
Amount of gallons of water after 6 hours is 482 gallons.

Answer:
The surface area of a rectangular prism can be calculated by adding the area of each of its six faces. The formula for the surface area of a rectangular prism with length l, width w, and height h is:
Surface Area = 2lw + 2lh + 2wh
So for a rectangular prism with length 29 inches, width 36 inches, and height 5 inches, the surface area can be calculated as follows:
Surface Area = 2 * 29 * 36 + 2 * 29 * 5 + 2 * 36 * 5
= 2,612 + 290 + 360
= 3,262 square inches
Therefore, the surface area of the rectangular prism is 3,262 square inches.

Solve for the length of the unknown side in the following right triangle. (Side AC is the hypotenuse.) Round your answer to two places, where applicable. Side AB 17, Side BC 22, Side AC ?
Answer:
27.87
Step-by-step explanation:
In a right triangle, the length of the hypotenuse can be found using the Pythagorean theorem, which states that the sum of the squares of the two shorter sides is equal to the square of the length of the hypotenuse.
Using the given sides, we can write the equation:
AB^2 + BC^2 = AC^2
Substituting the given values, we have:
17^2 + 22^2 = AC^2
Simplifying the left side, we get:
289 + 484 = AC^2
773 = AC^2
Taking the square root of both sides, we find:
AC = √773 = 27.87
Rounding to two decimal places, the length of side AC is approximately 27.87.

Answer:
[tex] \frac{14}{16} \: and \: \frac{13}{16} [/tex]
Step-by-step explanation:
So we have these two fractions
[tex] \frac{7}{8} \: and \: \frac{13}{16} [/tex]
Does 8 go into 16? Yes. It goes in twice because 8 times 2 is 16. That means 16 is our common denominator.
Because of that, since we multiplied 8 by 2, we will do the same to the 7. 7 times 2 is 14.
Because of that we have 14/16 and 13/16 as our answers.

The given matrix is:
| 1 0 5 |
| -2 1 -6 |
| 0 2 8 |
We must compute the matrix's determinant in order to determine if the matrix's column vectors are linearly independent or linearly dependent.
A scalar value that can be used to assess linear dependency or independence is the determinant of a matrix.
The determinant of the matrix is:
det(A) = 1(-68) - 0(18) + 5(-2*2) = -6 + 0 - 20 = -26
Since The column vectors of this matrix are linearly independent, meaning they are not dependent upon one another, and the determinant is not equal to 0.
