Question 5 options:

A) pythagorean theorem
B) perimeter
C) surface area
D) area

Answers

Answer: A) pythagorean theorem

Explanation:

You are probably familiar with the formula [tex]a^2+b^2 = c^2[/tex] which is the pythagorean theorem.

The [tex]a^2[/tex] is the square of the first leg 'a', while [tex]b^2[/tex] is the square of the second leg b. Adding those two squares leads to the square of the hypotenuse c, aka [tex]c^2[/tex]. This only works with right triangles, which are triangles that have a 90 degree angle.

Answer:

The formula you will want to use is y(2) - y(1) over x(2) over x(1).

Basically, the Y variables (4 and 1) will be subtracted from each other. Aka, 1-4, which is -3. You put that over 5-(-5) or (5+5) which is 10. Now you have -3/10.

Answer:

[tex]\frac{2}{5}[/tex] and [tex]\frac{2}{7}[/tex]

Step-by-step explanation:

We want to work backwards. Currently we have [tex]\frac{ }{ }[/tex][tex]\frac{?}{?}[/tex] ÷ 5 = [tex]\frac{2}{25}[/tex].

If we multiply both sides by 5, we get [tex]\frac{?}{?}[/tex] = [tex]\frac{2}{25}[/tex] × [tex]\frac{5}{1}[/tex].

We can use multiplication of fractions to solve this. To multiply fractions we multiply the two numerators together and multiply the two denominators together, giving an answer of [tex]\frac{?}{?}[/tex] = [tex]\frac{10}{25}[/tex].

This can be simplified to [tex]\frac{2}{5}[/tex].

We can use the same method on the other equation to get an answer of [tex]\frac{2}{7}[/tex].

Fill in the missing number. % of 60 = 24

Answers

Answer:

40%

Step-by-step explanation:

Step 1: Set up an equation.

[tex]\frac{x}{100}(60)=24[/tex]

Step 2: Simplify both sides of the equation.

[tex]\frac{x}{100}(60)=24[/tex] [tex]\frac{60}{100}x= 24[/tex] [tex]\frac{3}{5}x=24[/tex]

Step 3: Multiply both sides by 5/3.

[tex]\frac{3}{5}x* \frac{5}{3}=24 * \frac{5}{3}[/tex] [tex]x = \frac{120}{3}[/tex] [tex]x = 40[/tex]

Therefore, the missing number is 40 to make 40% of 60 = 24.

Determine whether the relation is a function. Explain pls

Answers

Answer:

The given relation is not a function.

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

Given the following relation: {(7, 4), (5, - 1), (3, - 8), (1, - 5), (3, 6)}

There is an input value (x = 3) that has two corresponding outputs (y-values): y = -8 and y = 6.  

Remember that a function can only take on one output for each input.

It also helps to do the Vertical Line Test, which allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.  To use the vertical-line test, imagine dragging a ruler held vertically across the  graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value.

Attached is a screenshot of the plotted points on a graph, where I performed the Vertical Line Test. The green line is the vertical line that contains two points that made the relation invalid as a function.
