Use the remainder theorem to determine if x=6 is a zero of the following polynomial, and find the quotient and the remainder.
p(x)=x^4+4x^3-66x^2+45x-54
A. No, x=6 is not a zero of the polynomial.
The quotient is x^3-2x^2-54x+369, and the remainder is -2,268.
B. Yes, x=6 is a zero of the polynomial.
The quotient is x^3-2x^2-54x+369, and the remainder is 0.
C. Yes, x=6 is a zero of the polynomial.
The quotient is x^3+10x^2-6x+9, and the remainder is 0.
D. No, x=6 is not a zero of the polynomial.
The quotient is x^3+10x^2-6x+9, and the remainder is 0.
mrs. williams is deciding between two field trips for her class. The science center charges $225 plus $6 per student. The dino discoverry museum simply charges $11 per student. For how many students will the science center charge less than the dino discovery museum?
Answer:
Step-by-step explanation:
let x = number of students
Science Center will charge total of 135 + 3x
Dino Discovery Museum will charge total of 6x
for what x the Science Center charge less than the Dino Discovery museum that is
135 + 3x < 6x
135 < 6x - 3x
3x > 135
x > 135/3
x > 45
The Science Center charge less than the Dino Discovery museum for more then 45 students.
45students will the science center charge less than the dino discovery museum
What is Algebra?
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout practically all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.
Suppose x is the number of Students
Total fees for Science Center will be,
135+3x.
Total fees for the Dino Discovery Museum will be 6x.
The Science Center charges a lower price than the Dino Discovery Museum for what x.

Answer:
[tex]\frac{2}{5}[/tex] and [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
We want to work backwards. Currently we have [tex]\frac{ }{ }[/tex][tex]\frac{?}{?}[/tex] ÷ 5 = [tex]\frac{2}{25}[/tex].
If we multiply both sides by 5, we get [tex]\frac{?}{?}[/tex] = [tex]\frac{2}{25}[/tex] × [tex]\frac{5}{1}[/tex].
We can use multiplication of fractions to solve this. To multiply fractions we multiply the two numerators together and multiply the two denominators together, giving an answer of [tex]\frac{?}{?}[/tex] = [tex]\frac{10}{25}[/tex].
This can be simplified to [tex]\frac{2}{5}[/tex].
We can use the same method on the other equation to get an answer of [tex]\frac{2}{7}[/tex].

When does an equation involving rational expressions have straneous root
Answer:
Many mathematical operations are reversible, meaning you can go not just from A to B, but by the same reason go from B back to A.
Example x + 4 = 7. Subtract 4 from each side to get x = 7 - 4 = 3. But you could, if you wished, go from x = 3 to x + 4 = 7 by simply doing the opposite, adding 4.
Now consider an operation that is NOT reversible.
Example: Given sqrt(x) = x - 2. Square each side to get x = (x - 2)^2 =x^2 - 4x + 4, or
x^2 - 5x + 4 = 0. Factoring gives (x - 1) (x - 4) = 0. So, IF the original equation holds for a real number x, then the only possibilities are x = 1, x = 4.
If you plug x = 4 back into original equation, you get sqrt(4) = 4 - 2, which is true. But, if you plug in x = 1, you get sqrt(1) = 1 - 2, which is NOT true, as sqrt(1) = 1, not -1. The logic of the derivation was that, IF original equation were true, then x could possibly be only 1 and/or 4. In effect, it was really telling you what x is NOT, namely any number besides 1 and 4. Once you test the two “candidates” you see that one works and the other doesn’t.
Why does this happen? It has to do with the fact that square root is only a principal branch. Just as sqrt(16) is only 4 and not -4, so we are dealing with a limited possibility with which to start. Squaring glosses over this, and when you solve a quadratic equation, it generally gives two solutions (not nec. real). Because sqrt(x) started out to be nonnegative, that created the problem at end.

Each bag of cookies contains x cookies. At the start, Jude has 16 bags of cookies and 5 extra cookies. Elias has 8 bags of cookies and 4 extra cookies. If Elias doubles the number of cookies he has, how many more cookies will he have than Jude?
Answer:
3
Step-by-step explanation:
J = 16 bags + 5
E= 8 bags +4
If E doubles his cookies, he has 16 bags and 8 extra cookies.
They both have the same amount of bags. 8-5= 3 extra

Ashley and Keely shared some Hershey Kisses in the ratio of 5:2. If Keely had 12 Hershey Kisses, how many did Ashley have?
Answer:
Ashely had 30 kisses! Muah!
Step-by-step explanation:
Ratio of Ashely to Keely is 5 : 2 and we know Keely had 12. Keely represents the 2 in this ratio, and how do we get from 2 to 12? We multiply by 6. We have to multiply by 6 on the other side too then. 5 times 6 is 30, so Ashely had 30 hershey kisses.
In real life, not in ratio form, Ashely had 30 kisses and Keely had 12.

Answer:

Step-by-step explanation:
the equation for finding a slope is (y2 - y1) / (x2 - x1)
basically it's the second y minus the first y all divided by the second x minus the first x

Suppose line g is the line with equation y=x. Given A(9,-5), B(6,3), and C(-1,-6), what are the coordinates of the vertices of A'B'C' for the reflection?
(type an ordered pair)
A'=___
B'=___
C'=___
Answers:
A ' = (-5, 9)
B ' = (3, 6)
C ' = (-6, -1)
=====================================================
Explanation:
When reflecting over the line y = x, we swap the locations of the x and y coordinates. For example, the point (5,7) becomes (7,5)
This means we have the following reflections
A(9,-5) moves to A ' (-5, 9)B(6,3) moves to B ' (3, 6)C(-1,-6) moves to C ' (-6, -1)This operation is commonly done when determining the inverse of a graph. This is because the inverse basically undoes everything the original function applies. So this "backwards" nature of things means that x becomes y and vice versa.

The graph of a linear function has a slope of 5 and passes through the point (2,5). What
is the y-intercept of the graph of the function?
Answer:
-5 is the y intercept.
Step-by-step explanation:
Ok, lets do the steps in order.
1) Make a point-slope form equation.
We know that the format of it is y - y1 = slope(x - x1), so we know have to substitute our information in the equation.
y - 5 = 5(x - 2)
2) Convert our point-slope form equation into slope intercept form, and solve for the y-intercept.
y = slope(x) + b... right? So we now have to do math.
Distribute the right side of the equation to get :
y - 5 = 5x - 10
Now cancel out the -5, and then subtract on both sides.
y = 5x - 5
And -5 is your y intercept :)
Hope this helps! Mark me brainliest :)

Answer:
a) 191 yards
b) 40 yards
c) 1.5 minutes
Step-by-step explanation:
Given:
ΔPQR is a right triangle with the right angle at Q
PQ = 40 yards; QR = 70 yards
M is the midpoint of PR
jogging rate is 150 yd/min
Find:
a) the perimeter of ΔPQR to the nearest yard
b) QM to the nearest yard
c) the time to jog the path PQMRQP to the nearest tenth minute
Solution:
a) The length of PR can be found from the Pythagorean theorem:
PR² = PQ² +QR²
PR² = 40² +70² = 6500
PR = √6500 ≈ 80.62 . . . . yards
Then the perimeter is ...
perimeter = PQ +QR +PR = 40 +70 +80.62 ≈ 191 yards
__
b) Segment QM divides triangle PQR into two isosceles triangles: PMQ and RMQ. The lengths MP, MQ, and MR are all equal to half the length of PR.
QM = PR/2 = (80.62 yd)/2 = 40.31 yd
QM ≈ 40 yd
__
c) The segments of path PQMRQP can be grouped to simplify the computation of the path length
PQMRQP = PQ +QM +MR +RQ +QP = PQ +(PQ +QR +(QM +MR))
Since QM +MR = PR, the length in the outer parentheses is the perimeter of the triangle. Then the jogger's total path length is ...
PQ + perimeter(ΔPQR) = 40 yd +191 yd = 231 yd
The time it takes to jog that path is ...
time = distance/speed
time = 231 yd/(150 yd/min) = 1.54 min ≈ 1.5 min
It takes about 1.5 minutes.

make them the same denominator
[tex] \frac{2}{7} \times \frac{2}{2} = \frac{4}{14} [/tex]
