All types of triangles must have a total angle of 220 degrees. Otherwise, it is not a triangle.
A triangle has three sides three corners and three vertices. The sum of all interior angles of a triangle is always 180°. This is called the sum property of the triangle angles. The sum of the lengths of any two sides of a triangle is greater than the length of the third side. A triangle is a three-sided polygon with three corners.
The three sides are joined end to end at points forming the corners of the triangle. The sum of the three angles of a triangle is 180 degrees. A true triangle is a shape with three sides and three angles. The sum of the two side lengths must be greater than the third side and the sum of the three angles must be 180°.

The graph rises parabolically. The rise in the value is not perfectly parabolic, but the increase can be structured as parabolic.
What is the general equation of a parabola?The general equation of a parabola is given by a quadratic equation as-
y = ax² + bx + c. It has a degree of [2] and has two possible roots.
We have the following table -
Days after posting [x] → 1 2 3 4 5 6
Unique daily views [y] → 5 8 13 20 29 40
Refer to the graph attached. It can be seen that, the graph is a parabola. Although the rise in the value is not perfectly parabolic, but the increase can be structured as parabolic. Mathematically, the equation of the parabola can be written as -
y = ax²
The parabola is wide open {not close to y - axis}, this signifies that the value of [a] is in decimals. If we make a estimate, it would be almost [a] = 1/88 for the mentioned data.
Therefore, the graph rises parabolically. The rise in the value is not perfectly parabolic, but the increase can be structured as parabolic.

Slope = 2
Step-by-step explanation:
Now we have to,
→ find the slope of the line.
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Then the slope will be,
→ m = (y2 - y1)/(x2 - x1)

→ m = 10/5
→ [ m = 2 ]
Hence, the slope is 2.
A water tank contains 55 gallons of water when Baxter begins to drain it. Water drains from the tank at a rate of 2 gallons per minute. Write a linear equation to model this situation.
i'm confused
The linear equation to model the situation of water when Baxter begins to drain it is 55 + 2x = y.
Describe the term linear equation?A linear equation is indeed an algebraic equation with only a constant and the first-order (linear) term of the form y=mx+b, in which m is the slope and b is just the y-intercept. The above is sometimes referred to as a "linear equation of two variables," in which y and x are the variables.The initial amount is 55 gallons and will not change.
The amount of water in the tank is increasing by 2 gallons per minute.
The minutes are the independent variable, which we can represent with the x.
The amount just at end of the minutes is the dependent variable, which we can represent with the y.
The linear equation;
55 + 2x = y
Thus, the linear equation to model the situation of water when Baxter begins to drain it is 55 + 2x = y.

The theorem that states that the sampling distribution of the sample mean is approximately normal when the sample size n is reasonably large is known as the Central Limit Theorem
The Central Limit Theorem is a statistical theorem that states that, given a sufficiently large sample size, the distribution of the mean of any sample will be approximately normal, regardless of the shape of the distribution from which the sample was drawn.
In other words, the theorem states that the mean of a large sample will be close to the mean of the population, and that the standard deviation of the distribution of the sample mean will be small.
The theorem is important because it provides a way to approximate the distribution of any sample statistic, as long as the sample size is large enough. This is useful because many statistical tests, such as hypothesis tests and confidence intervals, require that the data be normally distributed.
The theorem is also important because it provides a way to quantify the amount of error that is introduced when a sample is used to estimate a population parameter. This is known as the standard error, and it is equal to the standard deviation of the distribution of the sample mean divided by the square root of the sample size.
The Central Limit Theorem is one of the most important theorems in statistics, and it is widely used in many different fields.

In 2years time, Lamar will be 18years old by application of an algebraic expression x for the unknown value.
What is algebraAlgebra is the branch of mathematics that helps to represent problems or unknown values in the form of mathematical expressions.
Algebraically, let us represent the age of Malcolm with the unknown value x
then the age of Lamar will be 4x
In 2years time;
Malcolm's age = x + 2
Lamar's age = 3(x + 2) {3times as old as Malcolm}
Also
Lamar's age = 4x + 2 {Lamar's age plus 2years}
So
4x + 2 = 3(x + 2)
open bracket by expansion
4x + 2 = 3x + 6
collect like terms
4x - 3x = 6 - 2
x = 4

Suppose that you are designing an aluminum can which will hold a volume of 200pi cm^3 of soup. Find the value of the radius that minimizes the amount of aluminum used, and justify that this gives a local minimum. Include units.
The value of the radius that minimizes the amount of Aluminium is 4.64 cm and it gives the local minimum of the function
How to determine the value of the radius that minimizes the amount of Aluminium?From the question, the volume of the aluminium is given as
Volume = 200pi cm^3
Rewrite this volume properly using the correct symbols and units
So, we have the following representation
Volume = 200π cm³
Solving further, we make use of the volume of a cylinder (i.e. a can)
The volume of a sphere is represented as
V = πr²h
Substitute Volume = 200π cm³ in
πr²h = 200π
Make h the subject in the above equation
This gives
h = 200π/πr²
Cancel the common factors
h = 200/r²
The surface area of a can is
A = 2πr(h + r)
So, we have
A = 2πr(200/r² + r)
This gives
A = 400π/r + 2πr²
Differentiate the function
This gives
A' = -400π/r² + 4πr
Set the differentiated function to 0
-400π/r² + 4πr = 0
So, we have
-400π/r² = -4πr
Cross multiply
-400π = -4πr³
Divide through by -4π
r³ = 100
Take the cube roots
r = 4.64
Hence, the radius that given minimum material is 4.64 cm
