Given:
[tex]f(x)=x^3+4x^2+5x+2,k=-2[/tex]
To find:
The the given function in the form [tex]f(x)=(x-k)q(x)+r[/tex].
Solution:
We have,
[tex]f(x)=x^3+4x^2+5x+2[/tex]
The coefficients of f(x) are 1, 4, 5, 2.
Divide the given function by (x+2) by using synthetic division as shown below:
-2 | 1 4 5 2
-2 -4 -2
_____________________
1 2 1 0
_____________________
Bottom row represent the quotient and last element of the bottom row is the remainder.
Degree of the function is 3 and the degree of division is 1. So, the degree of the quotient is 3-1 = 2.
So, the quotient is [tex]x^2+2x+1[/tex] and the remainder is 0.
Now,
[tex]f(x)=(x-k)q(x)+r[/tex]
Here, q(x) is the quotient and r is the remainder.
[tex]f(x)=(x-k)(x^2+2x+1)+0[/tex]
Therefore, the required answer is [tex]f(x)=(x-k)(x^2+2x+1)+0[/tex].

reduce 105 in the ratio 3:5
9514 1404 393
Answer:
39.375 : 65.625
Step-by-step explanation:
The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.
3/8 × 105 = 39 3/8
5/8 × 105 = 65 5/8
The divided quantities are ...
39.375 : 65.625

In the relationship between hours driven and distance traveled is y = 45x, which of the following ordered pairs would be graphed on the line that represents the relationship?
Step-by-step explanation:
(0,0) (1,45) (2,90) (3, 135) (4, 180) etc, etc
Answer:
(4, 180)
Step-by-step explanation:
Choices: (3,5), (4,60), (4,180), (5,9)
y = 45x
The value of y is 45 times the value of x.
The only point in which that is true is (4, 180) since 45 * 4 = 180.
Answer: (4, 180)

Is it possible for a cross section of a cylinder to have a triangular shape?
It is not possible for a cross section of a cylinder to have a triangular shape
What is cross section?Cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces
What is Cylinder?A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes
What is triangular shape?A triangle is a shape formed when three straight lines meet
Cross section of the cylinder is depends on how we cut .The cross-section of a cylinder may be either circle, rectangle, or oval
Hence, the cross section of of a cylinder can not be a triangular shape

Answer:
y=9.75x+60
Step-by-step explanation:
We want our equation to look like y=mx+b
Let's start out by calculating the slope
[tex]\frac{118.5-89.25}{6-3}=9.75[/tex]
we have
y=9.75x+b
we know that when x= 3 y= 89.25
89.25=9.75(3)+b
solve for b = 60

The width of a rectangle is 2 3/8 inches. The rectangle is 1 3/4 inches longer than it is wide Find the Length of the rectangle and preimeter of the rectangle
Answer:
We need to find length and width. To find two unknowns we need two equations.
P = 2L + 2W = 34
L = W + 3
34 = 2(W + 3) + 2W
34 = 2W + 6 + 2W
28 = 4W
W = 7
L = 7 + 3 = 10
The length is 10 inches and the width is 7 inches.

The union decides to sammple 348 of its members at random and monitor the working time of each of them for 1 month. At the end of the month the total number of hours absent from work is recorded for each employee . if the mean and standard deviation of the sample are x = 7.5 hours and s = 3.5 hours, find a 99% confidence interval for the true mean number of hours a union member is absent per month. Round to the nearest thousandth.

Answer:
restrictions exclude parts of the domain where the function is not defined. On a graph, they are holes, or vertical asymptotes.the denominator might be (x² -4)they are different in the same way that adding and multiplying numerical fractions are differentStep-by-step explanation:
1. In general, restrictions on rational functions refer to values of the variable that make the denominator zero. The function will be undefined in that case. On a graph, such a location will show up as a "hole" or a vertical asymptote.
__
2. If ±2 are excluded from the domain, we expect factors of (x-2)(x+2) in the denominator. That is, the denominator will have a factor of (x²-4). (There may be other factors that do not have real zeros.)
__
3. A rational expression is a fraction the same as any other. The usual rules of addition, subtraction, multiplication, and division apply. For addition and subtraction, it can be useful to identify a common denominator. For multiplication and division, that is not so essential.
