Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's assertion correct?.
Answers
No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
Perpendicular linesIn order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:
[tex]m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1[/tex]
For the slope of ln:
[tex]m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\[/tex]
For the slope of mn:
[tex]m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\[/tex]
If any of the two lines is perpendicular, hence the triangle lmn is right-angled.To check, we will take the product of the slopes and see if it is equivalent to -1.Product of slope lm and ln
[tex]m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2[/tex]
Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

Two numbers differ by 8 if their product is 713 then the sum of the two numbers is.
Answers
The sum of the two numbers is equal to 70.
Let the first number be x.Let the second number be y.In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
[tex]x-y=8[/tex] ....equation 1.
The product of the two numbers is 713:
[tex]xy=713[/tex] ....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
[tex]x=8+y[/tex] ....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
[tex]y(y+8)=713\\\\y^2+8y=713\\\\y^2+8y-713=0[/tex]
Solving the quadratic equation by factorization, we have:
[tex]y^2-31y +23y-713=0\\\\y(y-31)+23(y-31)=0\\\\(y+23)(y-31)=0[/tex]
y = -23 or 31.
For the value of x, when y = 31:
[tex]x=8+31[/tex]
x = 39
Now, we can calculate the sum of the two numbers:
[tex]x+y=39+31=70[/tex]

The piecewise expression presented in the question gives values of f(x)
that change based on the range of the input value, x.
The graph of the piecewise expression f(x) is attachedReasons:
The given piecewise function is presented as follows;
[tex]f(x) = \begin{cases}2 \cdot x - 1, & \text{ if } x < 0 \\0, & \text{ if } x = 0\\-2 \cdot x + 1, & \text{ if } x > 0 \end{cases}[/tex]Required:
To find the graph of f(x)
Solution:
From the piecewise function, we have;
For x < 0, f(x) = 2·x - 1The slope, m = 2
Therefore, as x tends to 0, f(x) tends to 2×0 - 1 = -1
Therefore, for x < 0, the graph starts with an open circle at f(x) = -1, and f(x) decreases as graph moves from right to left.
At x = 0, f(x) = 0, which represent a point on the graphFor x > 0, f(x) = -2·x + 1
Which gives that as x tends to 0, f(x) tends to +1
The slope of the graph, m = -2
Therefore, the graph is a straight line that starts with an open circle at f(x) = +1 and slopes downwards from left to right.

You are performing an experiment in a lab to attempt a new method of producing pure elements from compounds. The only problem is that you do not know what element will form. By your previous calculations you know that you will have 6. 3 moles of product. When it is complete, you weigh it and determine you have 604. 4 grams. What element have you produced?.
Answers
Answer:
molybdenum (Mo)
Explanation:
For this question you need to understand what the concept of molar mass is.
Molar mass is the exact mass by which you will obtain a mol of that specific element. For example the molar mass of H2O is 18g/mol, so it means that in 18 grams of water, you exactly have 6.022x10²³ molecules of water or one mole.
So here you know the number of moles you produce and its conversion to grams. The problem is basically stating that in 604.4 grams of x element you have 6.3 moles of that element.
All you have to do is divide the number of grams by the number of moles:
604.4grams/6.3 moles=95.94 g/moles,
You obtained the molar mass of that X element, and in fact the molar mass corresponds the molecular mass of all elements, that is an information provided by the periodic table. So all you have to do is look for the element with a molecular mass of 95.94 uma or a very close approximate.
Molybdenum has a molecular mass of 95.95. So that's the answer.
