Evaluate the integral. (Use C for the constant of integration). integral t/t^4 + 5 dt
The value of integral is [tex]\frac{1}{2 \sqrt{5}} \tan ^{-1}\left(\frac{t^2}{\sqrt{5}}\right)+C$$[/tex]
The Integral is [tex]$$\int \frac{t}{t^4+5} d t$$[/tex]
Indefinite integrals are not defined using the upper and lower limits. The indefinite integrals represent the family of the given function whose derivatives are f, and it returns a function of the independent variable.
The integration denotes the summation of discrete data. The integral is calculated to find the functions which will describe the area, displacement, volume, that occurs due to a collection of small data, which cannot be measured singularly.“Integral is based on a limiting procedure which approximates the area of a curvilinear region by breaking the region into thin vertical slabs.Let [tex]$t^2=u= > t d t=\frac{d u}{2}$[/tex]
The above Integral becomes
[tex]$\frac{1}{2} \int \frac{1}{u^2+(\sqrt{5})^2} d u=\frac{1}{2 \sqrt{5}} \tan ^{-1}\left(\frac{u}{\sqrt{5}}\right)+C$$[/tex]
Substitute u In terms of t
[tex]$$\int \frac{t}{t^4+5} d t=\frac{1}{2 \sqrt{5}} \tan ^{-1}\left(\frac{t^2}{\sqrt{5}}\right)+C$$[/tex]
Therefore, the value of integral is [tex]\frac{1}{2 \sqrt{5}} \tan ^{-1}\left(\frac{t^2}{\sqrt{5}}\right)+C$$[/tex].

From a 200-foot observation tower on the beach, a man sights a whale in difficulty. The angle of depression of the whale is 7 degrees. How far is the whale from the shoreline?
Whale is 1628.87 feet far from the shoreline.
What is angle of depression?The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line. It is basically used to get the distance of the two objects where the angles and an object's distance from the ground are known to us.
Given,
Height of the tower = 200 feet
Angle of depression = 7°
Distance of whale from the shore line = x = AB = ?
In the figure
tan 7° = BC/AB = 200/AB
0.1228 = 200/AB
AB = 1628.87 feet = x
Distance of whale from the shoreline = 1628.87 feet.
Hence, Whale and shoreline are 1628.87 feet far from each other.

What is the y-intercept of Y =- 10?
The y-intercept of Y = - 10 is -10.
If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.
The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, b, represents the y-coordinate of the point where the graph of the line intersects the y-axis.
Now, if we equate the standard slope-intercept form of the equation with the given equation, we get
y = mx + c
y = - 10 = 0x -10
m = 0 and c = -10
As we know the c is the y-intercept which is equal to -10.

The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is,
⇒ x²+ (y - 6)² = 36
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Now, We know that;
The standard form for finding the equation of a circle is expressed as;
⇒(x - a)² + (y - b)² = r²
where; (a, b) is the center of the circle and r is the radius of the circle.
Here, we have;
⇒ Diameter = 12 units
⇒ Radius = 12/2 = 6 units
Since, The center lies on the y-axis,
Hence, the center will be at (0, 6).

In other words, they represent the range of values which a number may have taken had it not been rounded off or truncated.The numbers 10.3 and 10.5 are below and above, respectively (to 1 decimal place)

If XV =27-2x and VZ =3x+2, find VZ and XZ
If XV =27-2x and VZ =3x+2, then the diagonal of parallelogram XZ = 34 units and VZ = 17 units.
What is a parallelogram?
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size.
The length of line XV = 27 - 2x.
The length of line VZ = 3x + 2.
According to the properties of a parallelogram the diagonals bisect each other .
Hence, XV = VZ.
Equating the expressions -
27 - 2x = 3x + 2
-2x - 3x = 2 - 27
-5x = -25
x = 5
The value of line XV = 27 - 2x
27 - 2(5)

17 units
The value of line VZ = 3x + 2
3(5) + 2

The function f(x) is stretched vertically by a factor of 3 and horizontally by a factor of 12 and is translated down 5 units to obtain the function g(x).
Question 1
What is the value of A, the amplitude of the function?
Enter your answer in the box.
The amplitude of a sine or cosine function is the vertical stretch or compression factor of the function. In this case, the function f(x) = sin(x) has been stretched vertically by a factor of 3. Therefore, the amplitude of the function g(x) is A = 3.

The values of x and y that are solutions to the system of simultaneous equations are; y = 573/25 and x = 17.1
How to solve the system of linear equations?We are given the simultaneous equations;
²/₃x + ³/₅y = 12 -----(eq A)
⁵/₂y - 3x = 6 ------(eq B)
Multiply eq A by 9 and eq B by 2 to get;

25y + 27 = 600
25y = 600 - 27
25y = 573
y = 573/25
Thus;

f(x) = x⁵ – 8x⁴ + 16x³ at x = 4, does not cross the x-axis. at x = 0, crosses the x-axis. This relates to the x-axis end behavior of a graph of a function.
What is meant by Function?A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output.A function, which generates one output from a single input, is an illustration of a rule. The photographer is Alex Federspiel.Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.An input is connected to an output by a function. It resembles a device with an input and an output.Let's now find the roots of this function;
f(x) = x⁵ - 8x⁴ + 16x³
Let's factorize it first to get;
f(x) = x³(x² – 8x + 16)(x² – 8x + 16) is a perfect square trinomial and can be expressed as (x – 4)(x - 4).
Thus; f(x) = x³ (x – 4)(x - 4)
C) Since we have found the factorized form to be;
f(x) = x³ (x – 4)(x - 4)
The roots are at f(x) = 0;
The roots are; x³ = 0; (x – 4) = 0 ; (x - 4) = 0
This indicates that x=0 and x=4 are f(xroots. )'s x = 4
As a result, the graph will touch the x-axis but not the repeated root of 4, which indicates that the graph has a repeated root.

Recursive equation :
A equation for one term that depends on another. If we want to generalize this sequence, we can achieve this by first defining the first term and then describing how the subsequent terms relate to one another. Recursive representation of a sequence occurs when the connection between its succeeding terms is described.Thus,
For the given question;
Common ratio or difference : 90% or 0.9.

Thus, Recursive equation : f(n) = f(n - 1) + 9
Explicit equation :
Based on the term number, a formula for just any term.We explicitly represent a series when we have a formula that allows us to find any term as in sequence without considering any other terms.Thus,
