Determine whether \triangle X Y Z is an acute, right, or obtuse triangle for the given vertices. Explain.
X(-3,-2), Y(-1,0), Z(0,-1)
Triangle XYZ with vertices X(-3 , -2), Y(-1 , 0), and Z(0 , -1) is a right triangle.
First, using the distance formula, find the length of each side of the triangle: side XY, side XZ, and side YZ.
d = √(x2 - x1)^2 + (y2 - y1)^2
side XY : d = √(-1 - -3)^2 + (0 - -2)^2 = √4 + 4 = 2√2
side XZ : d = √(0 - -3)^2 + (-1 - -2)^2 = √9 + 1 = √10
side YZ : d = √(0 - -1)^2 + (-1 - 0)^2 = √1 + 1 = √2
Next, check if it follows the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = XY = 2√2, b = XZ = √10, and c = YZ = √2
a + b > c 2√2 + √10 > √2 5.99 > 1.41 True
a + c > b 2√2 + √2 > √10 4.24 > 3.16 True
b + c > a √10 + √2 > 2√2 4.58 > 2.83 True
Lastly, to know what type of triangle based on the length of its side,
1. Take the sum of the squares of the two smaller sides.
(√2)^2 + (2√2)^2 = 10
2. Compare it to the square of the largest side.
(√10)^2 = 10
10 = 10
If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.
if they are equal, it is a right triangle.
if they are smaller, then it is an obtuse triangle.
Hence, triangle XYZ is a right triangle.

What is a fraction?A fraction can be defined as a numerical quantity which isn't expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.
The parts of a fraction.In Mathematics, a fraction comprises two (2) main parts and these include the following:
NumeratorDenominatorIn order to determine the length of the zoo railroad track which does not need to be replaced, we would add all of the length of the zoo railroad track that need to be replaced and then subtract this value from the total length of the zoo railroad track as follows:
Length of replacement = 62/2 + 83/8 + 63/4
Note: Lowest common denominator (LCM) = 8.
Length of non-replacement = (248 + 83 + 126)/8
Length of non-replacement = 457/8
Length of replacement = 500 - 457/8
Length of replacement = (4000 - 457)/8
Length of replacement = 3543/8 or 442.875.

Scientific notation exists as a method of writing very large or very small numbers. The expression as a number in scientific notation is 2.5 × [tex]10^5[/tex], 3.5 × [tex]10^{-7[/tex], 1 × [tex]10^{-8[/tex], 3.24 × [tex]10^{17[/tex],
What is meant by scientific notation?
Utilizing scientific notation, one can express extremely big or extremely small values. When a number between 1 and 10 is multiplied by a power of 10, the result is represented in scientific notation.
To express exceedingly high numbers in a shorter manner, scientists have created a shorthand. Scientific notation is the name of this technique. The foundation of scientific notation is the base-10 powers. The coefficient is defined as the initial number, 1.23.
The guidelines for writing scientific notation.
Always start with a base of 10.
The exponent may have both positive and negative values and must be a non-zero integer.
The absolute value of the coefficient is more than or equal to 1, even though it should be less than 10.
Whole numbers, decimal numbers, positive, negative, or both can all be used as coefficients.
The mantissa represents the remaining significant digits of the number.

Yall pls help me outtt! im having sm trouble with this problem
Step-by-step explanation:
Hello, and thank you for asking your question on Brainly!
This problem is basically telling is to isolate the variable g. But how are we to do so, when it's being sandwiched inside a variety of numbers and letters? The problem looks harder than it seems. But do not fret!
When you're in a trail in the woods and you get lost, the most logical thing is to do the opposite of where you just went in order to try and reach home. We can use this same analogy for math. We just try and use the opposite operation for every action that the function is being acted on!
Let be the original equation,
[tex]u=\sqrt{Ng+Q^3 }[/tex]
Looks pretty complicated right? We want to isolate the variable g, so let's get rid of this 'roof' over their heads.
To get rid of the square root, we can square both sides by two; this negates the square root, and opens up the right section of the equation.
[tex]u=\sqrt{Ng+Q^3 }[/tex]
[tex]u^2 =(\sqrt{Ng+Q^3 })^2[/tex]
[tex]u^2=Ng+Q^3[/tex]
Now, we have to make sure we get the variable g alone. Let's subtract Q cubed to the other side, we can subtract it over to get rid of it on the right hand side.
[tex]u^2=Ng+Q^3\\-Q^3 ~~~~~ -Q^3[/tex]
[tex]u^2-Q^3=Ng[/tex]
We're almost close! Now, all we have to do to isolate the variable g is to divide the whole equation by N, so the right hand side it cancels out. This is the opposite of N multiplied by g.
[tex]\frac{u^2-Q^3}{N} =g[/tex]
It wasn't so bad now, was it? I hope this helped! g is now isolated and this is the end of the problem.

Step-by-step explanation:
it is simple for such a line.
x goes to -infinity, and therefore y (or f(x)) also goes to -infinity.
x goes to +infinity, and therefore y (or f(x)) also goes to +infinity.
the difference between x and y values is just a constant factor (the slope). that constant factor becomes irrelevant, when the values approach infinity anyway. only the sign is relevant.
but in our case the slope is +1/+2 (the y value increases by +1 for every increase of x by +2).
so, the line (as we can see in the graph) is
y = 1/2 × x - 1
when x goes to +infinity, "-1" is irrelevant, and
1/2 × +infinity = +infinity.
when x goes to -infinity, again, "-1" is irrelevant, and
1/2 × -infinity = -infinity
Write the contrapositive of the statement. If an angle measures greater than 90°, then it is obtuse.
The contrapositive of the statement will be : if it is not obtuse, then an angle does not measure greater than 90° .
We need to know about conditional and contrapositive statement to solve this problem.
A conditional statement takes the form "If p, then q" where p is the hypothesis while q is the conclusion. So, here in this problem p is 'an angle measures greater than 90° and q is it is obtuse.
The Contrapositive of a Conditional Statement is obtained by supposing that you have the conditional statement p→ q. Now, we first find the inverse of the given conditional statement then swap the roles of hypothesis (p) and conclusion (q) . Therefore, the contrapositive of the conditional statement p→ q is ~q → ~p.
Thus, contrapositive of the statement : If an angle measures greater than 90°, then it is obtuse will be if it is not obtuse, then an angle does not measure greater than 90° .

If z varies directly with the product of x and y(z=k x y) , then z is said to vary jointly with x and y .
b. Suppose q varies jointly with v and s , and q=24 when v=2 and s=3 . Find q , when v=4 and s=2
The value of q for the given relation will be 32.
What is direct variation?
A sort of proportionality known as "direct variation" occurs when one quantity immediately changes in response to a change in another variable.
This suggests that if one number increases, the other quantity will also rise proportionately. Similar to the last example, if one quantity declines, the other amount likewise declines. The link between direct variation and the graph will be linear, resulting in a straight line.
As q varies jointly with v and s,
It implies that
q = k v s
Given,
q=24 when v=2 and s=3
24 = k × 2 × 3
k = 24 / 2 × 3
k = 4
When we put v = 4 and s = 2
⇒ q = 4 × v × s
⇒ q = 4 × 4 × 2

You should note that you chose the side lengths. This implies that you might choose differently. This allowed you to create an infinite number of distinct triangles using the same angles.
