We want to evaluate
[tex]\displaystyle \int_{-\frac1{\sqrt2}}^{\frac1{\sqrt2}} \sqrt{\left(\frac{x-1}{x+1}\right)^2 + \left(\frac{x+1}{x-1}\right)^2 - 2} \, dx[/tex]
First we note that the integrand is even (replacing x with -x doesn't fundamentally alter the function being integrated), so this is equal to
[tex]\displaystyle 2 \int_0^{\frac1{\sqrt2}} \sqrt{\left(\frac{x-1}{x+1}\right)^2 + \left(\frac{x+1}{x-1}\right)^2 - 2} \, dx[/tex]
The radicand reduces significantly to
[tex]\displaystyle \left(\frac{x-1}{x+1}\right)^2 + \left(\frac{x+1}{x-1}\right)^2 - 2 = \frac{16x^2}{(1-x^2)^2}[/tex]
so that taking the square root, we simplify the integral to
[tex]\displaystyle 8 \int_0^{\frac1{\sqrt2}} \frac x{1-x^2} \, dx[/tex]
which is trivially computed with a substitution of [tex]y = 1 - x^2[/tex] and [tex]dy=-2x\,dx[/tex]:
[tex]\displaystyle -4 \int_1^{\frac12} \frac{dy}y = 4 \int_{\frac12}^1 \frac{dy}y = -4 \ln\left(\frac12\right) = \ln(2^4) = \boxed{\ln(16)}[/tex]

The expression below is a sum of cubes.
125x^3 + 144
A. True
B. False
Answer:
False
Step-by-step explanation:
Hey there!
If this is a sum of cubes, this means that both numbers have whole numbers as the cube root of that number
The cube root of 125 is 5
But the cube root for 144 is a decimal meaning this is not a sum of cubes
Future value of 10% savings from earnings of1470 earning 3.5% annual interest compounded monthly for 25 years
hmmm so let's see first how much is 10% of the earnings of 1470.
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{a\% of b}\\ \cline{1-1} \\ \left( \cfrac{a}{100} \right)\cdot b \\\\ \cline{1-1} \end{array}~\hspace{5em}\stackrel{\textit{10\% of 1470}}{\left( \cfrac{10}{100} \right)1470}\implies 147[/tex]
so then
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$147\\ r=rate\to 3.5\%\to \frac{3.5}{100}\dotfill &0.035\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{monthly, thus twelve} \end{array}\dotfill &12\\ t=years\dotfill &25 \end{cases}[/tex]
[tex]A=147\left(1+\frac{0.035}{12}\right)^{12\cdot 25}\implies A=147\left( \frac{2407}{2400} \right)^{300}\implies \boxed{A\approx 352.19}[/tex]
Use a fraction or mixed number to represent the time on a number line. Let 0 represent noon.
8:30 A.M.
The time 8:30AM is 3 and half hours before noon.
The fraction that represents 8:30AM is -3 1/2
How to represent the time as fraction?The time is given as:
Time = 8:30 A.M
Given that Noon is represented by 0.
It means that time before noon would be represented with negative value
8:30AM is 3 and half hours before noon.
So, we have:
8:30AM = -3 1/2
Hence, the fraction that represents 8:30AM is -3 1/2

Builtrite bonds have the following: 5 1/2% coupon, 10 years until maturity, $1000 par and are currently selling at $1044. If you purchase this bond, what would be your AYTM?
The annual yield to maturity (AYTM) of the Builtrite bonds is at 5.5% for 10 years with a $1,000 par value and the current price of $1,044 is A. 4.9%.
What is the annual yield to maturity (AYTM)?The annual yield to maturity (AYTM) is the total return expected from a bond if the bond is held till maturity.
The AYTM rate is the rate at which all future expected cash flows are discounted to find out the current value or the price of the bond.
We can use the following Yield to Maturity formula to calculate the AYTM.
Yield to Maturity = [Annual Interest + {(FV-Price)/Maturity}] / [(FV+Price)/2]
Data and Calculations:Annual Interest = Annual Interest Payout by the Bond = $55 ($1,000 x 5.5%)
FV = Face Value of the Bond = $1,000
Price = Current Market Price of the Bond = $1,044
Maturity = Time to Maturity = 10 years
= {$55 + ($1,000 - $1,044)/10} / {($1,000 + $1,044)/2}
= $55 + -4.4 / 1,022
= 50.6/1,022
= 4.95%
We can also use an online finance calculator to check the calculated value above as follows:
N (# of periods) = 10
I/Y (Interest per year) = 4.95%
PMT (Periodic Payment) = $55 ($1,000 x 5.5%)
FV (Future Value) = $1,000
Results:
PV = $1,044
Sum of all periodic payments = $550 ($55 x 10)
Total Interest $503.44
Answer Options:A. 4.9%
B. 5.1%
C. 5.3%
D. 5.5%
Thus, the annual yield to maturity (AYTM) of the Builtrite bonds is at 5.5% for 10 years with a $1,000 par value and the current price of $1,044 is A. 4.9%.

Is there a relationship between the distance and the sum? Is there a relationship between the distance and the difference? A 5-column table with 3 rows. Column 1 is labeled a with entries 1, 4, negative 6. Column 2 is labeled b with entries 2, negative 1, negative 3. Column 3 is labeled a + b with entries 3, 3, negative 9. Column 4 is labeled a minus b with entries negative 1, 5, negative 3. Column 5 is labeled Distance with entries 1 unit, 5 units, 3 units. Which describes the relationship between the distance and the difference? The distance is always the opposite of the difference. The distance is exactly the difference. The distance is the absolute value of the difference. The distance is not related to difference.
Answer:
C) The distance is the absolute value of the differenceStep-by-step explanation:
We are interested in the last two columns.
If we compare them we see that each value of the distance column is the absolute value of corresponding value of difference:
a - b = 1, 5, - 3distance = 1, 5, 3Corect choice is C
Answer:
The distance is the absolute value of the difference.
Step-by-step explanation:
Given table:
[tex]\begin{array}{|c|c|c|c|c|}\cline{1-5} a & b & a+b & a-b & \sf distance\\\cline{1-5} 1 & 2 & 3 & -1 & 1 \sf \: unit\\\cline{1-5} 4 & -1 & 3 & 5 & 5 \sf \: units\\\cline{1-5} -6 & -3 & -9 & -3 & 3 \sf \: units\\\cline{1-5}\end{array}[/tex]
The difference is column 4.
The distance is column 5.
The absolute value of a number is its positive numerical value. It is denoted by a vertical line either side of the real number.
For example, |5| means 'the absolute value of 5', and |-5| means 'the absolute value of -5'.
Taking the absolute values of the differences:
⇒ |-1| = 1
⇒ |5| = 5
⇒ |-3| = 3
Therefore, the distance is the absolute value of the difference.

Volume =

Answer:
111.3 cubic inches
Step-by-step explanation:
The dimensions of the rectangular prism are 5.9 x 3.4 x 5.1
volume = length x width x height
V = 5.9 x 3.4 x 5.3
V = 102.306
The dimesnsions of the triangular prism are 3.4 x 5.9 x ?
to find the missing length, 6 - 5.1 = 0.9
3.4 x 5.9 x 0.9
Volume = (3.4 x 5.9 x 0.9)/2
V = 18.054/2
V = 9.027
Add the volumes together
102.306 + 9.027 = 111.333

An angle measures 26.8° less than the measure of its complementary angle. What is the measure of each angle?
Given :
An angle which measures 26.8° less than the measure of its complementary angle.⠀
To Find :
The measure of each angle.⠀
Solution :
Let's assume the one of the complementary angle as "x" and the other angle as (x – 26.8)° .⠀
Now,
⠀
According to the Question :
⠀
[tex]{\longrightarrow \qquad \sf{ x + {(x - 26.8)}^{ \circ} = {90}^{ \circ} }}[/tex]
⠀
[tex]{\longrightarrow \qquad \sf{ x + {x - 26.8}^{ \circ} = {90}^{ \circ} }}[/tex]
⠀
[tex]{\longrightarrow \qquad \sf{ 2 {x - 26.8}^{ \circ} = {90}^{ \circ} }}[/tex]
⠀
[tex]{\longrightarrow \qquad \sf{ 2 x = {90}^{ \circ} + 26.8^{ \circ}}}[/tex]
⠀
[tex]{\longrightarrow \qquad \sf{ 2 x = 116.8^{ \circ}}}[/tex]
⠀
[tex]{\longrightarrow \qquad \sf{ x = \dfrac{116.8^{ \circ}}{2}}}[/tex]
⠀
[tex]{\longrightarrow \qquad \frak{\pmb{ x =58.4^{ \circ}}}}[/tex]
⠀
Therefore,
One angle = 58.4°Other angle = 58.4° – 26.8° = 31.6°⠀
Hence,
The measure of the each angles are 58.4° and 31.6° .Answer:
The measurement of each angle is 58.4° and 31.6°
Step-by-step explanation:
Given :-
Value of an angle is 26.8° less than its complementary angleTo Find :-
Measurement of each angleSolution:-
let one angle be x and other be x - 26.8°
we know that, Sum of complementary angle is 90°
X + X - 26.8° = 90°
2x = 90° + 26.8°
x = 58.4
So , one angle is 58.4° and other one is 58.4 - 26.8 which is 31.6

When you divide this, you get 0.8888...
So the fraction that represents 0.888... is 1111/1250
A fraction that represents the decimal 0.8888 is: 1111/1250
What is fraction?In Mathematics, fractions are represented as a numerical value, can be defined as the parts of a whole. A fraction can be a portion or section of any quantity out of a whole, where, the whole can be any number, a specific value, or a thing.
Given is decimal number 0.8888... we need to convert it into a fraction,
Since the number has 4 decimal places, then the first thing to do is multiply and divide the number by 10000.
We have then:
0.8888* (10000/10000) = 8888/10000
Simplifying we have:
8888/10000 = 4444/5000
