Required Answer for the given question[tex]\sf{=}{\sf{\dfrac{ x^{2}}{2}}}{\sf{ + 7x + 67x .In| x - 4 | - 30.In| x - 3 | + c }}[/tex]
Answer:
[tex]\displaystyle \large{\frac{x^2}{2}+7x+67\ln |x-4|-30\ln |x-3| + C}[/tex]
Step-by-step explanation:
To find an integration of this function, first, you must know these integration methods and differences of them.
Partial Fraction Method - A method that separates the denominator into two brackets and solve the equation for two variables.Long Division Method - A method that uses long division to rewrite the fraction to make it easier to integrate.These methods above are common when it comes to integrating fractional functions, except there are differences when to use these methods.
Partial Fraction technique has to be used when the degree of numerator is lower than the degree of denominator. Basically, proper fraction.Examples (of these integrands that require partial fraction technique)
[tex]\displaystyle \large{\int \frac{3}{x^2-5x+6} \ dx}\\\displaystyle \large{\int \frac{x+2}{x^2-4} \ dx}[/tex]
Long Division technique has to be used when the degree of numerator is greater than the degree of denominator.Examples (of these integrands that require long division)
[tex]\displaystyle \large{\int \frac{x^2+5x+6}{x+2} \ dx}\\\displaystyle \large{\int \frac{x^4+3}{x} \ dx }[/tex]
Therefore, from the given integral, the integrand requires long division method. (See attachment for long division.)
After long division, we should get:
[tex]\displaystyle \large{\int x+7+\frac{37x-81}{x^2-7x+12} \ dx}[/tex]
Recall important properties of integral such as:
[tex]\displaystyle \large{\int [f(x) \pm g(x)] \ dx = \int f(x) \ dx \pm \int g(x) \ dx}[/tex]
Hence:
[tex]\displaystyle \large{\int x \ dx + \int 7 \ dx + \int \frac{37x-81}{x^2-7x+12} \ dx}[/tex]
Recall important integration formula for polynomial and constant:
[tex]\displaystyle \large{\int x^n \ dx = \frac{x^{n+1}}{n+1} + C}\\\displaystyle \large{\int x \ dx = \frac{x^2}{2} + C}\\\displaystyle \large{\int k \ dx = kx + C \ \ \tt{(k \ \ is \ \ a \ \ constant.)}[/tex]
Therefore:
[tex]\displaystyle \large{\frac{x^2}{2}+7x+\boxed{\int \frac{37x-81}{x^2-7x+12} \ dx}}[/tex]
From the boxed integral above, we cannot evaluate it by default. From what I said, if the degree of numerator is less than the degree of denominator, we’ll use partial fraction technique.
Therefore, factor the denominator:
[tex]\displaystyle \large{\frac{37x-81}{(x-4)(x-3)}}[/tex]
Set to A/x-4 and B/x-3
[tex]\displaystyle \large{\frac{37x-81}{(x-4)(x-3)} = \frac{A}{x-4} + \frac{B}{x-3}}[/tex]
Multiply both sides by (x-4)(x-3).
[tex]\displaystyle \large{\frac{37x-81}{(x-4)(x-3)} \cdot (x-4)(x-3)= \frac{A}{x-4} \cdot (x-4)(x-3) + \frac{B}{x-3} \cdot (x-4)(x-3)}\\\displaystyle \large{37x-81= A(x-3) + B(x-4)}\\\displaystyle \large{37x-81= Ax-3A+Bx-4B}\\\displaystyle \large{37x-81= (A+B)x-(3A+4B)}[/tex]
Then compare the coefficients:
[tex]\displaystyle \large{\left \{ {{A+B=37} \atop {3A+4B=81}} \right}[/tex]
Solve the simultaneous equation for A and B.
[tex]\displaystyle \large{\left \{ {{A=37-B} \atop {3A+4B=81}} \right}\\\displaystyle \large{\left \{ {{A=37-B} \atop {3(37-B)+4B=81}} \right}\\\displaystyle \large{\left \{ {{A=37-B} \atop {111-3B+4B=81}} \right}\\\displaystyle \large{\left \{ {{A=37-B} \atop {111+B=81}} \right}\\\displaystyle \large{\left \{ {{A=37-B} \atop {B=81-111}} \right}\\\displaystyle \large{\left \{ {{A=37-B} \atop {B=-30}} \right}\\\displaystyle \large{\left \{ {{A=67} \atop {B=-30}} \right}\\[/tex]
Therefore, A = 67 and B = -30. Substitute the values in:
[tex]\displaystyle \large{\int \frac{67}{x-4}-\frac{30}{x-3} \ dx}\\\displaystyle \large{\int \frac{67}{x-4} \ dx -\int \frac{30}{x-3} \ dx}[/tex]
Recall the integration formula for above:
[tex]\displaystyle \large{\int \frac{k}{x-a} \ dx = \int k \cdot \frac{1}{x-a} \ dx = k\ln |x-a| + C}[/tex]
Therefore:
[tex]\displaystyle \large{\int \frac{37x-81}{x^2-7x+12} \ dx = \int \frac{67}{x-4}-\frac{30}{x-3} \ dx = 67\ln |x-4| - 30\ln |x-3|}[/tex]
Back from this:
[tex]\displaystyle \large{\frac{x^2}{2}+7x+\boxed{\int \frac{37x-81}{x^2-7x+12} \ dx}}[/tex]
Substitute in:
[tex]\displaystyle \large{\frac{x^2}{2}+7x+67\ln |x-4|-30\ln |x-3| + C}[/tex]
Therefore the solution is:
[tex]\displaystyle \large \boxed{\frac{x^2}{2}+7x+67\ln |x-4|-30\ln |x-3| + C}[/tex]

HELP!! I dont know which one is the correct answer. I'll give brainliest
Answer:
As it says approximate, the nearest value to 46.6° is 45.6°
Therefore, 45.6° is the approximate measure of angle A.
using SOH CAH TOA:
[tex]\sf cos(A) = \dfrac{b^2+c^2-a^2}{2bc}[/tex]
[tex]\hookrightarrow \sf cos(A) = \dfrac{4^2+8^2-6^2}{2(8)(4)}[/tex]
[tex]\hookrightarrow \sf cos(A) = 0.6875[/tex]
[tex]\hookrightarrow \sf A = cos^{-1}(0.6875)[/tex]
[tex]\hookrightarrow \sf A = 46.5675^{\circ \:}[/tex]
[tex]\hookrightarrow \sf A = 46.6^{\circ \:}[/tex]

Graphing a line by first finding its x and y intercepts
Answer:
x-intercept is 5
y-intercept is -6
Step-by-step explanation:
To find x-intercept put y=0
since 6x-5y=30 then 6x=30
x=30/6 = 5
To find y-intercept put x=0
since 6x-5y=30 then -5y=30
y=30/-5 = -6

when a kitten is born it weighs 1.5 pounds. after 3 weeks it weighs 3 pounds. when the kitten is 6 weeks old it weighs 7.5 pounds. what percent weight gain did the kitten grow over from the first weight?
Answer:
It grew by 500% meaning it grew on average 83.333% per week
Step-by-step explanation:
To find the percent growth you divide the end weight by the starting weight:
[tex]7.5/1.5=5[/tex]
However, that is the percentage in decimal form. To convert that number to a percentage move the decimal place to the right 2 places. This results in 500%
To get the average weekly growth weight, simply divide the 500% by the amount of weeks (6). This then gives the 83.333% per week.
Note: I didn't know which answer you were looking for. That is why there are 2.

A helicopter company offers tours of the city. They charge $100 dollars initially, and then $50 for each additional person. The graph below shows the charges for a tour (T) based on the number of people (p).Write the equation of the line that relates the tour charges (T) to the number of people (p).
Answer:
100 + 50p = t or t = 100 + 50p
Step-by-step explanation:
We know that they charge 100 initially and then an addition 50 for each person.
We add 100 to 50 but we do not know the amount of people, which leaves it unknown (p)
The total cost (t) is also unknown which stays unknown until we calculate the amount of people.

Answer:
mDBC = 341 °
Step-by-step explanation:
Arc DBC is almost the whole circle, if you were to exclude the degree measure of minor arc DC; which is, in other words m∠ DPC
Now by Vertical Angles Theorem:
m ∠ DPC = m∠ APB, ⇒ provided BD, and AC are diameters
m∠ DPC = 19°
This would mean ⇒
mDBC = 360 - m∠ DPC,
mDBC = 360 - 19,
mDBC = 341 degrees ( ° )
