The antiderivative of f(x) = tan⁻¹(x) is x tan⁻¹(x) − ln(x²+1)/2 + C
The term antiderivative in math is referred as a function that reverses what the derivative does
Here we have given the expression f(x) = tan⁻¹(x).
Now, the antiderivative of the expression is calculated by doing the integral
=> ∫tan⁻¹(x)dx
By using the integration by parts ∫udv = uv−∫vdu
Here let us consider that u=tan⁻¹(x) and dv=dx
And the value of du is calculated as,
=> du = ∫tan⁻¹(x)dx = dx/(x² + 1)
And the value of v = x.
Then the expression is written as,
=> ∫tan⁻¹(x)dx = x tan⁻¹(x) - ∫x/(x² + 1)dx
As per the concept of the constant of integration, it can be simplified as,
=> x tan⁻¹(x) − ln(x²+1)/2 + C

please help me solve this:40= -3x+10
Answer:
x = -10
Step-by-step explanation:
Solve means to get the x all by itself on one side of the equation.
40 = -3x + 10
Subtract 10 from both sides.
30 = -3x
Divide both sides by -3.
30/-3 = x
-10 = x
x = -10
You can check your answer by putting it back into the equation and seeing if you get a true statement.
40 = -3x + 10
x = -10
Substitute.
40 = -3(-10) + 10
Multiply.
40 = 30 + 10
Add.
40 = 40
True! This means
x = -10 is correct.

If f(x)=root 4x+9+2 which inequality can be used to find the domain of f(x )
Answer:
x>=-11/4
Step-by-step explanation:
f(x)=[tex]\sqrt{4x+9+2}[/tex]
The number which has a square root has to be greater than or equal to 0.
Hence, 4x+9+2>=0
Solve the inequality:
4x+9+2>=0
4x+11>=0
4x>=-11 ==> subtract 11 on both sides to isolate x
x>=-11/4 ==> divide both sides by 4

Answer:
The boats cross paths at the points (1,8) and (4,11)
Step-by-step explanation:
First, we want to find the points of intersection between the two paths. We are given two equations, both in the form y=(equation). Since we want to find the intersection points, we set the two equations equal to each other (since both equal y we can plug one of the equations in for y into the other equation) to get
-x^2+6x+3=x+7
From here, we solve this like a normal quadratic equation, move all variables to one side first
-x^2+5x-4=0
This factors to -(x-1)(x-4)=0, giving us x=1 and x=4
Now we plug these back into one of the original equations (in this case the linear equation is much more simple) to give us the points (1,8) and (4,11)
What does changing the base of a log function do to the graph?
The larger the base of a log function, the closer the graph approaches the asymptote of x = 0.
We know that for a exponential function b^x = y, b is the base, y is the exponent to which the base b is raised and x is the result obtained.
We can write this in logarithmic form as:
log_b(x) = y
A logarithm base is the subscript of the logarithm that carries or raises the exponent.
For example in case of log_(3) 9 = 2, the base here is 3.
The change of base formula is:
log_b(x) = log_c(x) / log_c(b)
Also as we know the bigger the logarithm base, the smaller the curve on the graph. This means, the larger the base of a log function, the closer the graph approaches the asymptote of x = 0.
The log function may increase at a slower rate if the base increases.
Therefore, if the base of a log function is large, the graph approaches the asymptote of x = 0.

A shop charges `\$4. 95` for a large `9`-ounce frozen yogurt. What is the cost per ounce of the frozen yogurt?.
Answer:
$0.55/ounce
Step-by-step explanation:
The problem gives us the ratio of cost to ounce. We need to create a proportion (when you set two ratios equal to each other) to solve for one variable of the second ratio.
⭐ The first ratio is [tex]$4.95/9 ounces[/tex], which means that it costs $4.95 for 9 ounces.
⭐ The second ratio is [tex]x/1 ounce[/tex], where x is the cost for 1 ounce of frozen yogurt.
. . . . . . . "per ounce" means "for every 1 ounce"
⭐ We need to set these two ratios equal to each other and solve for x.
. . . . . . . In proportions, keep the units of the numerators and denominators the same. In this case, we'll keep the cost as the numerators and the ounces as the denominators.
. . . . . . . [tex]\frac{4.95}{9} = \frac{x}{1}[/tex]

The sum of two or more numbers that results in a third number is called a factor.
The factor of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex] exists 2x + 1.
What is meant by factors?The definition of a factor is a number that divides another number by itself with no remainder. In other words, if multiplying two whole numbers results in a product, the numbers we are multiplying are factors of the product since the product is divisible by them.
What can split a number exactly are factors. So there is no residual after division. Factors are the sums of two or more numbers that produce a third number. Consequently, a factor is a number that divides another.
The use of more variable factors—those whose values do fluctuate with output—occurs as production rises and falls. Workforce, energy, and directly used raw materials are examples of typical variable components.
Let the given equation be [tex]$& x^2+\frac{x}{6}-\frac{1}{6} \\[/tex]
[tex]$& =\frac{6 x^2+x-1}{6} \\[/tex]
simplifying the above equation, we get
[tex]$& =\frac{1}{6}\left(6 x^2+x-1\right)[/tex]
We will factorize the polynomial by splitting its middle term.
[tex]$& \frac{1}{6}\left(6 x^2+x-1\right) \\[/tex]
[tex]$& =\frac{1}{6}\left(6 x^2+3 x-2 x-1\right) \\[/tex]
simplifying the above equation, we get
[tex]$& =\frac{1}{6}(3 x(2 x+1)-1(2 x+1)) \\[/tex]
[tex]$& =\frac{1}{6}(3 x-1)(2 x+1)[/tex]
[tex]$\frac{1}{6^{}}(3 x-1)$[/tex] and (2x + 1) are factors of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex]

Answer:
Divide both sides by -3.
Step-by-step explanation:
This question is asking you how to get from step 1: [tex]-3(p-7) = -15[/tex] to step 2: [tex]p - 7 = 5[/tex].
We can see that the expression inside of the parentheses (p - 7) didn't go away from step 1 to step 2, and the term that was being multiplied by (p-7) had gone away. The only way you can "get rid" of a multiplied term is by doing the inverse of multiplication, which is division. Thus, you have to divide both sides by -3 to get to step 2.
B, D, E and F are points on a circle, centre O. ABC is a tangent to the circle. ODC is a straight line. BOE is a diameter of the circle. Angle BCD = 48° Find the size of angle DFE.
Answer:
m∠DFE = 69°
Step-by-step explanation:
The tangent of a circle is always perpendicular to the radius.
Therefore, as ABC is the tangent to the circle, and OB is the radius of the circle:
⇒ m∠CBO = 90°
Interior angles of a triangle sum to 180°. Therefore:
⇒ m∠COB + m∠CBO + m∠BCO = 180°
⇒ m∠COB = 180° - m∠CBO - m∠BCO
⇒ m∠COB = 180° - 90° - 48°
⇒ m∠COB = 42°
Angles on a straight line sum to 180°. Therefore:
⇒ m∠DOE + m∠COB = 180°
⇒ m∠DOE = 180° - m∠COB
⇒ m∠DOE = 180° - 42°
⇒ m∠DOE = 138°
The angle at the center is twice the angle at the circumference.
Therefore:
⇒ m∠DOE = 2 × m∠DFE
⇒ m∠DFE = m∠DOE ÷ 2
⇒ m∠DFE = 138° ÷ 2
⇒ m∠DFE = 69°
Which is a factor of the polynomial f x 6x 4 21x 3 4x 2 24x 35?
One of the factor of the given polynomial 6x^4 - 21x^3 - 4x^2 + 24x - 35 is (2x-7).
According to Rational Root Theorem,
Leading coefficient = 6
Trailing constant = 35
Factors of leading coefficient = 1, 2, 3, 6
Factors of trailing constant = 1, 5, 7, 35
Check for the rational roots
Let P = 7, Q = 2, then
P/Q = 3.5
F(P/Q) = 0
Apply Factor theorem which means the given polynomial must be divisible by P/Q, that is (2x-7)

Group 1 6x^4 - 21x^3
Take 3x^3 common, we get
3x^3(2x - 7)
Group 2 - 4x^2 + 24x - 35
When we divide it by (2x - 7) we get (-2x + 5)
⇒ - 4x^2 + 24x - 35 = (-2x + 5)(2x - 7)
⇒ 6x^4 - 21x^3 - 4x^2 + 24x - 35 = (2x - 7)(3x^3 - 2x + 5)

so, y=(1/4)x -10
First, find the slope of the line which is the value being multiplied by x. Therefore m=1/4
To find the slope perpendicular to the line you must find the negative reciprocal of 1/4. (Which just means change the sign then flip the fraction)
Multiplying 1/4 by -1 which is -1/4
Then flip the fraction and keep the sign with the numerator to find the reciprocal. So now it’s -4/1
