Answer:
p(x) = (x+6)(x-3)(x-5)p(x) = (x-2)(x+2)(x^2 +36)p(x) = x^3 -7x^2 -x +7p(x) = x^4 -5x^2 -36Step-by-step explanation:
Each root r gives rise to a binomial factor (x-r). Each complex root also has a conjugate root, so roots ±ri give rise to a binomial factor (x^2 +r^2).
__
1. p(x) = (x -(-6))(x -3)(x -5)
p(x) = (x+6)(x-3)(x-5)
__
2. p(x) = (x -2)(x -(-2))(x^2 +6^2)
p(x) = (x -2)(x +2)(x^2 +36)
__
If you want standard form, you can start with factored form, then multiply it out.
3. p(x) = (x -1)(x +1)(x -7) = (x^2 -1)(x -7) = (x^2 -1)x +(x^2 -1)(-7)
p(x) = x^3 -7x^2 -x +7
__
4. p(x) = (x -3)(x +3)(x^2 +2^2) = (x^2 -9)(x^2 +4)
p(x) = x^4 -5x^2 -36

Complete the expression so that it forms a perfect square binomial- 3x^2+18x
Answer:
-3x²+18x-27
Step-by-step explanation:
Given :
-3X²+18x
perfect square : (a+b)²=a² + 2ab + b²
[tex]\frac{-3x^{2} }{-3} +\frac{18x}{-3} ... something else[/tex] divide by -3 to have just a² type
x² -6x ...and something
compare with the perfect squere formula and we know a² is x² , a is x, so second term is 2xb and is -6x so b= -3
x²-6x+9 = (x-3)²
if you reverse and multiply by (-3) we have
-3x²+18x-27
aye i have a code karen someone help please
go to this question on my page and then go to the first answer and there's a Karen in the comments
"1. what do you do to check weather a number is rational or irrational? in your explanation, use an example of irrational and a rational number. 2. how does finding the square root of a number compare to finding the cube root of a number? use the number 64 in your explanation. REALLY HIGH BRAINIRLY"
Answer:
1. If you're taking square roots, the number must be a perfect square to give a rational root.
64 = 8^2, so √64 = 8 is rational
Similarly, since
64 = 4^3, ∛64 = 4 is rational.
For small numbers, it's easy to check for possible roots, as there aren't that many candidates. In general, it's much more difficult.

trig problem a dog walks 3.5 miles southeast then 8.2 miles north of east what is the resultant vector
Answer:
8.9miles
Step-by-step explanation:
Kindly find attached a rough sketch of the dog's movement.
Step one:
given data:
let the movement southeast be x,=3.5miles
and let the movement northeast be y=8.2 miles
let the resultant be z
Step two:
The resultant vector can be found using the Pythagoras theorem
z^2=x^2+y^2
z=√x^2+y^2
substituting we have
z=√3.5^2+8.2^2
z=√12.25+67.24
z=√79.49
z=8.9miles

The figure shows a pair of parallel line segments on a coordinate grid:
The line segments are translated 2 units to the left to form E′F′ and G′H′. Which statement describes E′F′ and G′H′? (1 point)
a
Line segments E′F′ and G′H′ intersect at (−2, 0) and are two times farther apart than EF and GH.
b
Line segments E′F′ and G′H′ intersect at (0, −2) and are two times farther apart than EF and GH. .
c
Line segments E′F′ and G′H′ do not intersect and are the same distance apart as EF and GH.
d
Line segments E′F′ and G′H′ do not intersect and are closer together than EF and GH.
Answer:
C
Step-by-step explanation:
translate 2 units to the left only means they are shifted to the left by 2 units nothing else changed

The question is asking us to find the y-values when f(x) = -2.
According to the graph, when f(x), or y, = -2, x has 2 points: -5 and -1.
Therefore, f(-5) = -2 and f(-1) = -2.

Q7)
A coffee shop owner would like to create a blend of cinnamon and hazelnut flavored coffee that
sells for $8.00 a pound. Currently, the cinnamon coffee sells for $6.00 per pound and the
hazelnut coffee sells for $9.00 per pound. Which of the following systems of equations could be
used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h,
in pounds, of the hazelnut flavored coffee, that should be mixed to obtain 20 pounds of the
desired blend?
The equation that is used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h, in pounds, of the hazelnut flavored coffee is c + h = 20 and 6c + 9h = 20(8)
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let c represent the amount of cinnamon flavored coffee, and h represent the amount in pounds, of the hazelnut flavored coffee.
The required blend is 20 pounds:
c + h = 20 (1)
Also:
6c + 9h = 20(8) (2)
From eqn 1 and 2:
The equation that is used to determine the amount c, in pounds, of the cinnamon flavored coffee, and the amount h, in pounds, of the hazelnut flavored coffee is c + h = 20 and 6c + 9h = 20(8)

help me (a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150 application fee.
Answer:
$1400x + $150
Step-by-step explanation:
Let the total cost of rent used for a month be $1400 plus a $150 application fee.
This means that;
Total cost (1 month) = $1400(1) + $150 = $1550
TO calculate the cost for x months, we will simply multiply x with the cost of rent for 1 month as shown.
The cost of rent for x month = 1400x * $150
The cost of rent for x month = $1400x + $150 (application fee are paid only once)
