show that a^12 can be written as a perfect square and a perfect cube
Answer:
Step-by-step explanation:
Doing this the long way, write a^12 as a product of "a"s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
Now group them into groups of 4
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube
Now do the same thing with groups of 6s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
a^12 = (a^6)^2
So the two answers are
Perfect cube: [(a^4)]^3
Perfect square: (a^6)^2

What are the coordinates of the point
3/4 of the way from a to b
Answer:
(-3.5,1.25)
Step-by-step explanation:
A is at -5,-4 and B is at -3,3
using the slope formula the slope has to be 3.5
meaning 3/4ths of the way is a translation of 1.5 right and 5.25 up making the coordinates (-3.5,1.25)
Solve for the value of N
Answer:
n = 17°
Step-by-step explanation:
The two angles are split by a 90° angle on a 180° line. This means that 44 and 3n - 5 must add up to 90.
3n - 5 + 44 = 90
Solve out left side
3n + 39 = 90
Subtract 39 from both sides
3n = 51
Divide both sides by 3
n = 17

Which statement best describes how to determine whether f(x) = 9 – 4x2 is an odd function?
Determine whether 9 – 4(–x)2 is equivalent to 9 – 4x2.
Determine whether 9 – 4(–x2) is equivalent to 9 + 4x2.
Determine whether 9 – 4(–x)2 is equivalent to –(9 – 4x2).
Determine whether 9 – 4(–x2) is equivalent to –(9 + 4x2).
Answer: C :Determine whether 9 – 4(–x)² is equivalent to –(9 – 4x²).
Step-by-step explanation:
A function f(x) is odd if f(-x)=-f(x).
We have thus to determine if 9-4*(-x)²= -(9-4*x²).
which is false since this function is even !!!

Answer:

Step-by-step explanation:
Find the sum S:
[tex]\displaystyle \large{S = \frac{1}{1 \cdot 3} + \frac{1}{2 \cdot 4} + \frac{1}{3 \cdot 5} + .... + \frac{1}{n(n+2)}}[/tex]
Please show your work too. Thank you!
Write the sum as
[tex]\displaystyle S = \sum_{k=1}^n \frac1{k(k+2)}[/tex]
Decompose the summand into partial fractions; that is, we look for constants a and b such that
[tex]\dfrac 1{k(k+2)} = \dfrac ak + \dfrac b{k+2}[/tex]
Condense the right side into a single fraction and set the numerators on both sides equal to one another:
[tex]\dfrac1{k(k+2)} = \dfrac{a(k+2)}{k(k+2)} + \dfrac{bk}{k(k+2)} = \dfrac{a(k+2)+bk}{k(k+2)} \\\\ \implies 1 = a(k+2) + bk = (a+b)k + 2a[/tex]
Then a + b = 0 and 2a = 1, so it follows that a = 1/2 and b = -1/2.
We then see that S is a telescoping sum (intermediate terms cancel and the overall sum collapses into a small number of terms):
[tex]\displaystyle S = \frac12 \sum_{k=1}^n \left(\frac1k - \frac1{k+2}\right) \\\\ S = \frac12 \left(1-\frac13 + \frac12 - \frac14 + \frac13 - \frac15 + \cdots + \frac1{n-2} - \frac1n + \frac1{n-1} - \frac1{n+1} + \frac1n - \frac1{n+2}\right) \\\\ S = \frac12 \left(1 + \frac12 - \frac1{n+1} - \frac1{n+2}\right) \\\\ \boxed{S = \frac{n(3n+5)}{4(n+1)(n+2)}}[/tex]

The answer is [tex]24/4=6 \hspace{0.1cm} and \hspace{0.1cm}4*6=24[/tex]. "unknown factor" pertains to finding an unknown value in a multiplication problem, while "quotients" refer to the results obtained in division operations.
Both concepts are fundamental in arithmetic and algebraic calculations.
In mathematics, "unknown factor" and "quotients" are related to multiplication and division, respectively:
1. **Unknown Factor:**
- An "unknown factor" refers to a number or variable that you want to find or determine in a multiplication problem.
- In the context of an equation like "a * b = c," where "a" and "b" are known values or variables, and "c" is the result of the multiplication, you might be trying to find the value of "a" or "b." The unknown factor is the value that you don't initially know, and you need to solve for it.
- For example, if you have the equation "3 * x = 15," the unknown factor is "x," and to find its value, you would need to divide both sides of the equation by 3, yielding "x = 5."
2. **Quotients:**
- "Quotients" is the plural form of "quotient," and it refers to the result of a division operation.
- In division, the quotient is the number that you get when you divide one number (the dividend) by another number (the divisor).
- For example, in the division problem "12 ÷ 4," the quotient is 3 because 12 divided by 4 equals 3. Here, 3 is the result or quotient of the division operation.
- Quotients can be whole numbers, fractions, or decimals, depending on the numbers being divided and the division process.
