What is the completely factored form of this polynomial (selected answer is wrong)
Answer: Option D.
Step-by-step explanation:
A straightforward way to solve this type of problems is to expand all the options and see which one fits the desired one.
First let's see which options we can discard.
The original polynomial is:
p(x) = 2*x^5 + 12*x^3 - 54*x
So the degree of this polynomial is 5.
We can see that in option B we have only 3 "x", then the degree of this polynomial will be 3, then this option can be discarded.
Now let's try with the other 3 options:
A) = 2*x*(x^2 - 3)*(x + 9)*(x - 9)
= 2*x*(x^2 - 3)*(x^2 - 81)
= (2*x^3 - 6*x)*(x^2 - 81)
= 2*x^5 - (2*x^3)*81 - 6*x^3 + 6*x*81
= 2*x^5 -168*x^3 + 486*x
We can see that the second and third coefficients are different than the ones we wanted, so this is not the correct option.
Now let's try option D.
D) = 2*x*(x^2 - 3)*(x^2 + 9)
= 2*x*(x^4 - 3*x^2 + 9*x^2 - 27) = 2*x*(x^4 + 6*x^2 - 27)
= 2*x^5 + 2*6*x^3 - (27)*2x
= 2*x^5 + 12*x^3 - 54*x
This is exactly what we wanted, so we can conclude that the correct option is D.
The area of the base is given by The volume of a hexagonal prism is given by 35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30 5x ^ 2 - 6 Find an expression for the height of the hexagonal prism.
Answer:
Step-by-step explanation:
The height of given hexagonal prism is 7x³+4x²-3x+5.
Given that, the volume of a hexagonal prism is [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] and the area of the base is 5x² - 6.
What is a hexagonal prism volume?A hexagonal prism is a three-dimensional solid shape with 8 faces that including hexagon bases.
Volume of a hexagonal prism = Area of a base × Height.
Here, [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] = 5x² - 6 × Height
Height = [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] ÷ 5x² - 6
5x² - 6| [tex]35x ^ 5 + 20x ^ 4 - 57x ^ 3 + x ^ 2 + 18x - 30[/tex] | 7x³+4x²-3x+5

The term-to-term rule for a sequence is " Add 1 and then double"
The first two terms are 2 and 6
Find the next term
The next term of the sequence is 14.
What is Sequence?A sequence in mathematics is a ordered set of objects or numbers which are related with something.
For example, 1, 3, 5, ..... is a sequence of odd numbers.
Given that,
The term-to-term rule for a sequence is " Add 1 and then double"
First term = 2
Second term = 6
6 is got by adding 1 to 2 and then doubling it.
2 + 1 = 3
3 × 2 = 6
In the same way,
Third term = (6 + 1)2 = 7 × 2 = 14
Hence the next term of the sequence is 14.

Ben starts walking along a path at 2 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 7 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Answer:
Amanda will catch up Ben after 0.6 hours.
Step-by-step explanation:
Amanda begins jogging along the same path at 7 mi/h.
This means that Amanda's position, after t hours, is given by:
[tex]A(t) = 7t[/tex]
Ben starts walking along a path at 2 mi/h.
Amanda leaves after one and a half hour, which means that Ben will be at position 2*1.5 = 3. So Ben's position after t hours is given by:
[tex]B(t) = 3 + 2t[/tex]
How long (in hours) will it be before Amanda catches up to Ben?
This will happen when:
[tex]A(t) = B(t)[/tex]
So
[tex]7t = 3 + 2t[/tex]
[tex]5t = 3[/tex]
[tex]t = \frac{3}{5}[/tex]
[tex]t = 0.6[/tex]
Amanda will catch up Ben after 0.6 hours.
It would take Amanda 0.6 hours or 6/10 hours to catch up with Ben.
This question comes from a topic in mathematics called rates and it's used to compare two values with each other and how one value affects the other value.
Let s represent the distance Amanda travels until she meet Ben.
We can set a timer on our phone when she leaves in order to track the time taken.
Let t represent the time taken.
Set of EquationWe can come up with two equations from these scenario
d - 3 = 2t------ equation (i)d = 7t ----- equation (ii)Substitute equation (ii) into equation (i)
[tex]7t -3 =2t[/tex]
collect like terms
[tex]7t-2t=3\\5t=3\\t=3/5\\t=0.6[/tex]
From the above, we can see it took her 0.6 hours to catch up with Ben.

A. 7 + or - 1.960 (2.29/underroot 8).

D. 7 + or - 2.306 (2.29/underoot 8).
E. 7 + or - 2.306 (2.29/underoot 9).
Answer:
Population mean = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]
Step-by-step explanation:
Given - A university researcher wants to estimate the mean number
of novels that seniors read during their time in college. An exit
survey was conducted with a random sample of 9 seniors. The
sample mean was 7 novels with standard deviation 2.29 novels.
To find - Assuming that all conditions for conducting inference have
been met, which of the following is a 94.645% confidence
interval for the population mean number of novels read by
all seniors?
Proof -
Given that,
Mean ,x⁻ = 7
Standard deviation, s = 2.29
Size, n = 9
Now,
Degrees of freedom = df
= n - 1
= 9 - 1
= 8
⇒Degrees of freedom = 8
Now,
At 94.645% confidence level
α = 1 - 94.645%
=1 - 0.94645
=0.05355 ≈ 0.05
⇒α = 0.5
Now,
[tex]\frac{\alpha}{2} = \frac{0.05}{2}[/tex]
= 0.025
Then,
[tex]t_{\frac{\alpha}{2}, df }[/tex] = 2.306
∴ we get
Population mean = x⁻ ± [tex]t_{\frac{\alpha}{2}, df }[/tex] ×[tex]\frac{s}{\sqrt{n} }[/tex]
= 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]
⇒Population mean = 7 ± 2.306 × [tex]\frac{2.29}{\sqrt{9} }[/tex]

Find three positive numbers whose sum is 140 and whose product is a maximum. (Enter your answers as a comma-separated list.)
Answer:
[tex]\frac{140}{3}, \frac{140}{3}, \frac{140}{3}[/tex]
Step-by-step explanation:
Let the numbers be [tex]x, y\ and\ z.[/tex]
Such that:
[tex]x + y + z = 140[/tex]
Make z the subject
[tex]z = 140 -x - y[/tex]
For their product to be maximum, we have:
[tex]f(x,y,z) = xyz[/tex]
Substitute [tex]z = 140 -x - y[/tex] in [tex]f(x,y,z) = xyz[/tex]
[tex]f(x,y) = xy(140 - x - y)[/tex]
Open bracket
[tex]f(x,y) = 140xy - x^2y - xy^2[/tex]
Differentiate w.r.t x and y
[tex]f_x=140y - 2xy - y^2[/tex]
[tex]f_y=140x - x^2 - 2xy[/tex]
Since the products are maximum, then [tex]f_x = f_y = 0[/tex]
For [tex]f_x=140y - 2xy - y^2[/tex]
[tex]140y - 2xy - y^2 = 0[/tex]
Factorize:
[tex]y(140 - 2x - y) = 0[/tex]
Split
[tex]y = 0\ or\ 140 - 2x - y = 0[/tex]
Make y the subject
[tex]y = 0\ or\ y = 140 - 2x[/tex]
For [tex]f_y=140x - x^2 - 2xy[/tex]
[tex]140x - x^2 - 2xy = 0[/tex]
---------------------------------------------------
Substitute y = 0
[tex]140x - x^2 -2x*0 = 0[/tex]
[tex]140x - x^2 = 0[/tex]
Factorize
[tex]x(140 - x)= 0[/tex]
[tex]x = 0\ or\ 140-x = 0[/tex]
[tex]x = 0\ or\ x = 140[/tex]
---------------------------------------------------
Substitute [tex]y = 140 - 2x[/tex]
[tex]140x - x^2 - 2xy = 0[/tex]
[tex]140x - x^2 - 2x(140 - 2x) = 0[/tex]
[tex]140x - x^2 - 280x + 4x^2 = 0[/tex]
Re-arrange
[tex]4x^2 -x^2 +140x - 280x = 0[/tex]
[tex]3x^2 -140x = 0[/tex]
Factor x out
[tex]x(3x - 140) = 0[/tex]
Divide through by x
[tex]3x - 140 = 0[/tex]
[tex]3x = 140[/tex]
[tex]x = \frac{140}{3}[/tex]
Recall that: [tex]y = 140 - 2x[/tex]
[tex]y = 140 - 2 * \frac{140}{3}[/tex]
[tex]y = 140 - \frac{280}{3}[/tex]
Take LCM
[tex]y = \frac{140*3-280}{3}[/tex]
[tex]y = \frac{140}{3}[/tex]
Recall that:
[tex]z = 140 -x - y[/tex]
[tex]z = 140 - \frac{140}{3} - \frac{140}{3}[/tex]
Take LCM
[tex]z = \frac{3 * 140- 140 - 140}{3}[/tex]
[tex]z = \frac{140}{3}[/tex]
Hence, the numbers are:
[tex]\frac{140}{3}, \frac{140}{3}, \frac{140}{3}[/tex]
