B 7.07
C [tex]\sqrt{50}[/tex]
Step-by-step explanation:
[tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
[tex]5^{2}[/tex] + [tex]5^{2}[/tex] = [tex]c^{2}[/tex]
25 + 25 = [tex]c^{2}[/tex]
50 = [tex]c^{2}[/tex]
[tex]\sqrt{50}[/tex] = [tex]\sqrt{c^{2} }[/tex]
[tex]\sqrt{50}[/tex] = c This is the exact answer. [tex]\sqrt{50}[/tex] is an irrational number. This means that it never terminates or repeats in the decimal form.

Answer(s):
[tex]5\sqrt{2}[/tex] and [tex]7.07[/tex]
Step-by-step explanation:
substitute a=5 and b= 5 into Pythagorean Theorem:

Slope intercept form become C = 10 + 0.20m
What do you mean by linear equation?
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.
Both linear equations with one variable and those with two variables exist.
The standard form or the general form of linear equations in one variable is written as, Ax + B = 0; where A and B are real numbers, and x is the single variable.
Slope intercept form is y = mx + c where m is the slope and c is the y-intercept.
It is given that an Uber driver charges a $10 pick-up fee plus $0.20 per mile.
Let m be the total miles.

Explain how you know that <4 and <6 are the same side interior angles
Angles ∠4 and ∠6 are the same side interior angles.
Interior angles are defined as the inner of two angles formed when two sides of a polygon intersect. Any of the four angles are formed when a third line intersects a pair of parallel lines.
If two angles are on opposite sides of a transversal, they are alternate. A transversal is a line that runs parallel to two horizontal lines. The alternate angles are alternate interior angles if they are located between the two parallel lines. The alternate angles are alternate exterior angles if they are located outside of the two parallel lines.
Angles ∠4 and ∠6 are known as alternate interior angles based on the information provided. As a result, you have the following options:
They are located on opposing sides of the transversal.
They are located between the two lines crossed by the transversal.
Therefore Angles ∠4 and ∠6 are the same side interior angles.

What are set operations?Set operations are the operations that are applied on two or more sets to develop a relationship between them.
Let mathematics = M, physics = P, chemistry = C.

n(M) = 48
n(P) = 40
n(C) = 44
n(M∩P) = 20
n(M∩C) = ?
n(C∩P) = 24
n(M∩P) + n(M∩C) + n(C∩P) - 3n(C∩P∩M) = 32
20 + n(M∩C) + 24 - 3n(C∩P∩M) = 32
n(M∩C) = 3n(C∩P∩M) - 12 - *
We know,
n(M∪P∪C) = n(M) + n(P) + n(C) - n(M∩P) - n(M∩C) - n(C∩P) + n(C∩P∩M)
80 = 48 + 40 + 44 - 20 - n(M∩C) - 24 + n(C∩P∩M)
n(M∩C) = n(C∩P∩M) + 8 -
Equating
n(C∩P∩M) + 8 = 3n(C∩P∩M) - 12
2n(C∩P∩M) = 20
n(C∩P∩M) = 10
Putting the value of n(C∩P∩M) in *
n(M∩C) = 18
n(M∩C) - n(C∩P∩M) = 8

The fraction 3/5 fits into 2 1/5 more or less than 1? That means the quotient is more or less than 1?
The fraction 3/5 fits into 2 1/5 more than once. The quotient is more than one.
We are given two fractions. The first fraction is 3/5, which is a simple fraction. The second fraction is 2 1/5, which is a mixed fraction. We will first convert the mixed fraction into a simple fraction.
F = 2 1/5
F = (2*5 + 1)/5
F = 11/5
We need to find out if the quotient is more or less than one. So we will divide the second fraction by the first fraction. Let the quotient be represented by the variable "Q".
Q = (11/5)÷(3/5)
Q = (11/5)×(5/3)
Q = 11/3
Q = 3.667
We can see that the quotient is more than one. Hence, the fraction 3/5 fits into 2 1/5 more than once.

A continuous function that has a domain of [-3, 4] will include all the values as -3,-2,-1,-0,-1,-2,3,4
What do you mean by continuous function?
In mathematics, a continuous function is one where a continuous variation of the argument results in a continuous variation of the function's value (i.e., a change without a leap). This indicates that there aren't any discontinuities, or sudden changes in value. More specifically, a function is continuous if it is possible to guarantee that its value will not vary significantly even with arbitrarily tiny changes to its parameter. Any function that is not continuous is said to be discontinuous.
It is given that a continuous function has a domain of [-3,4]
According to the definition of closed interval,
[-3,4] will contain all the elements between them and including them.
Therefore, [-3,4] will contain elements as -3,-2,-1,-0,-1,-2,3,4

Find the slope and y-intercept of the graph of the linear equation. Write your answers in simplest form.
y=9.5
Slope: ?
y-intercept: ?
Answer:
0, 9.5
Step-by-step explanation:
We can rewrite the equation as [tex]y=0x+9.5[/tex].
Comparing this to slope-intercept form, the slope is 0 and the y-intercept is 9.5.
What is the equation of the line that passes through the points (5,3) and
(5,-2)?
Answer:
x = 5
Step-by-step explanation:
I'm going to assume that this is asking you to graph in Slope-Intercept form, but if I am mistaken, comment on my answer and I will happily change it.
Slope-Intercept form:
y = mx + b
You leave y and x as variables, while m and b are to be substituted for slope and y-intercept. y-intercept is when x=0, where a point on a line is on the y axis.
To help you learn, for example, we have an equation is slope-intercept form:
y = 8x + 3
In this case, the slope is 8 and the y intercept is 3 as m is the slope and b is the y-intercept.
The slope is the steepness of the graph. The value of the slope is how much the y-value increases if the x-value increases by 1.
We can find the slope from 2 points using this formula:
[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we plug in our points into the formula.
[tex]\frac{-2-3}{5-5}[/tex]
Simplify.
[tex]\frac{-5}{0}[/tex]
Anything divided by 0 is undefined. This means the line we are graphing is completely vertical, known as undefined. We can only get this if the x value stays the same no matter what. In this case, the x value stays the same when the y value changes, meaning a undefined slope.
We have a special case here. If the slope is undefined, we do not use y = mx+b. Instead, we use:
x = what the x values of the 2 points are
x values of both points: 5
x = 5
