1. Solve for BC using Law of Cosines. Round to the nearest tenth when necessary.
Using cosine law in the triangle given, the length of BC is 32 units
What is Law of CosineThe law of cosines (also known as the cosine formula) is an equation that relates the lengths of the sides of a triangle to the cosine of one of its angles. It states that:
a² = b² + c² - 2(b)(c) Cos(A)
In the given problem, the data;
AB = 29AC = 23BC = ?angle A = 75°Substituting the values into the formula and solve for BC;
BC² = 29² + 23² - 2(29)(23) Cos 75
BC² = 1024.735393
BC = √1024.735393
BC = 32.01
BC ≈ 32
The length of side BC in the triangle is 32 units

What is the sum of angles in spherical geometry?The sum of angles of a triangle formed in a spherical geometry exists equivalent to 180∘.
A category of non-Euclidean geometry, spherical geometry is a subset of elliptical geometry. Any type of geometry that is not founded on conventional planes is known as non-Euclidean geometry. Lines in non-Euclidean geometry are not always the usual straight lines found in Euclidean geometry (i.e., plane geometry).
We require opposing sides and angles in order to use the sine rule. We can utilise this knowledge to locate the side that is opposite the other angle if we know two angles and one of the sides opposite. Accuracy points may be lost because of this.

What is the value of x
Answer: 104
Step-by-step explanation:
Angles at a line are equal to 180 degrees so:
180 = 72 + (x + 4)
180 = x + 76
180 -76 = x + 76 -76
104 = x
which equation represents the line that psses through (2,3) and (-2,5)
The equation of line that passes through (2,3) and (-2,5) is y = (-1/2)x + 4.
What is the equation of line that passes through the given points?The point-slope form is expressed as;
( y - y₁ ) = m( x - x₁ )
Where m is slope, x₁ and y₁ are the coordinates of the point .
Given the data in the question;
Point 1 (2,3)
x₁ = 2y₁ = 3Point 2 (-2,5)
x₂ = -2y₂ = 5First, determine the slope.
Slope m = (y₂ - y₁)/(x₂ - x₁)
Slope m = ( 5 - 3 ) / ( -2 - 2)
Slope m = 2 / -4
Slope m = -1/2
Plug the slope m = -1/2 and point (2,3) into point-slope formula and simplify.
( y - y₁ ) = m( x - x₁ )
( y - 3 ) = (-1/2)( x - 2 )
y - 3 = (-1/2)x - (-1/2)2
y - 3 = (-1/2)x + 1
y = (-1/2)x + 1 + 3
y = (-1/2)x + 4
Therefore, the equation of the line is y = (-1/2)x + 4.

The equation 3x62x10x4 is true for all real numbers. The equation 6x22x4x1 has no solution. When do you think an equation has all real numbers as its solutions?
When an equation simplifies to 0=0 then it has true for all real numbers or else it does not have solution.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
3x +6 = 2x +10 +x -4
Subtract (3x+6) from both sides:
(3x +6) -(3x +6) = (2x +10 +x -4) -(3x +6)
0 = x(2 +1 -3) +(10 -4 -6)
0 = 0
0 = 0 . . . . has "all real numbers" as a solution set
6x +2 -2x = 4x +1
Subtract (4x+1) from both sides:
(6x +2 -2x) -(4x +1) = (4x +1) -(4x +1)
x(6 -2 -4) +(2 -1) = 0
0x +1 = 0
1 = 0
Does not have "all real numbers" as a solution set. There is no solution

A polynomial function of degree 0 or 1 is a linear function in calculus and related subjects if its graph is a straight line. Any function that depicts a straight line on a coordinate plane is said to be linear. For instance, y = 3x - 2 is a linear function since it depicts a straight line on the coordinate plane. f(x) = 3x - 2 can be used to represent the function since f(x) can be linked to y.

confusion of the inverse occurs when we incorrectly believe _______.
The concept given is a Probability, It is a branch of mathematics that deals with the occurrence of a random event. The answer is P(A|B)=P(B|A).
Probability is the branch of mathematics concerning numerical descriptions of how probable an event is to do, or how likely it's that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Inverse probability is the probability of unobserved effects; or, more technically, the probability distribution of an unobserved variable. It's generally considered an obsolete term.
In probability proposition and statistics, an inverse distribution is the distribution of the complementary of an arbitrary variable. Inverse distributions arise in particular in the Bayesian environment of previous distributions and posterior distributions for scale parameters.

What is System of Linear Equation ?An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, whereas B is a constant. A linear equation with two variables has the standard form Ax + By = C. Here, the variables x and y, the coefficients A and B, and the constant C are all present.
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
A linear equation is an algebraic equation in which each term has an exponent of 1, and which, when plotted on a graph, always yields a straight line. It is called a "linear equation" for this reason.

True or False
You can use the same name (identifier). It may be a different object. They both loop will not affect each other.
Inside the inner or second loop, there is no way to refer to the object used in the first loop (unless you make special bread for that, as by providing a pointer to it).
This is Normally bad style, is prone to confusion, and should be avoided.
The objects are different only if the inner one is defined alone, as with the int I you have shown. If the same name is used without shaping a new object, the loops will use the same object and will interfere with each other.

A) 25
B) 50
C) 144 1/4
D) 156 1/4
I have the right answer, show work please
Answer:
156 1/4
Step-by-step explanation:
Assume the room is a square.
side = 12 1/2 ft
area = (side)²
area = (12 1/2 ft)²
area = (12 1/2 ft) × (12 1/2 ft)
area = (144 + 6 + 6 + 1/4) ft²

Which of the following tables may represent a linear function?
The table that represents a linear equation is the first one, and the line can be:
y = -4x - 1
Which of the following tables can represent a linear function?A general linear function can be written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
Now, notice that if we evaluate the line in x + 1, we will get:
y = a*(x + 1) + b
y = a*x + a + b
So, for an increase of one unit on the variable x, we have a constant increase in the y value.
Now, if you look at the first table, you can see that for each increase of 1 unit on the value of x, the value of y decreases by 4.
So that is the table that can represent a linear function.
And the line is:
y = -4x - 1
