Which of the following functions is graphed below?
Answers
observing the graph of the problem, it is evident that the solution is option D, since the graph of the parabola presents a domain for x <4 and the line presents a domain for x> = 4 and the only option with these two conditions is option D
using a graph tool
I proceed to verify
see the attached figure
the answer is the option D
The graph consists of two parts: left part (with sign < or ≤) - parabola and right part (with sign > or ≥) - straight line.
Determine signs:
From the diagram you can see that the right endpoint (4,19) of parabola is not included. This means that x cannot be equal to 4 at this part of graph and the sign should be <.
Also you can see that the left endpoint (4,8) of line is included. This means that x=4 belongs to the right part and the sign should be ≥.
Using previous conclusions, you can state that correct choice is D.

G let z be a random variable with a standard normal distribution. find the indicated probability. p(z ≤ −0.27)
Answers
The probability P(Z <= -0.27) in a standard normal distribution is determined by finding the corresponding right-tail probability of Z = 0.27 and subtracting it from 1, reflecting the distribution's symmetry.
To find the probability P(Z \<= -0.27), we use the properties of the standard normal distribution, which is symmetric about zero. The probability of Z scoring below -0.27 is equal to the probability of Z scoring above 0.27 due to this symmetry. Looking up the corresponding value for Z = 0.27 in a standard normal table, or using a calculator, we would find the right-tail probability. To get our desired left-tail probability for Z = -0.27, we subtract this from 1. For example, if the right-tail probability for Z = 0.27 was 0.3936, then P(Z \<= -0.27) would be 1 - 0.3936 = 0.6064.
An electronics shop offers a small ic chip for $1.50 per unit and $4.00 for large ic chip. on a certain day, 2200 chips were sold and $5050 is collected. how many small ic chips and how many large ic chips were sold?
Answers
.. s + l = 2200
.. 1.50s +4.00l = 5050
Solving these by your favorite method gives
.. s = 1500
.. l = 700
1500 small ICs and 700 large ICs were sold.
To determine the number of small and large IC chips sold, we set up a system of linear equations with the given total number of chips (2200) and total earnings ($5050). Solving the system, we found that 1500 small IC chips and 700 large IC chips were sold.
To solve the problem, we can set up a system of linear equations to represent the sales for small and large IC chips. We have two unknowns: the number of small IC chips (let's call it x) and the number of large IC chips (let's call it y). We have two pieces of information to create our equations:
The total number of chips sold is 2200, so x + y = 2200.
The total amount collected is $5050, so 1.50x + 4.00y = 5050.
Solving this system of equations, we multiply the first equation by 1.50 to align it with the second equation:
1.50x + 1.50y = 3300 (Multiply the first equation)
1.50x + 4.00y = 5050 (Second equation)
Subtracting the first new equation from the second gives us:
2.50y = 1750
Dividing both sides by 2.50 to find y gives us y = 700. That means 700 large IC chips were sold. Now, we can substitute y in the first equation to find x:
x + 700 = 2200
x = 2200 - 700
x = 1500
Hence, 1500 small IC chips and 700 large IC chips were sold.

The chemical formula for lithium phosphide is Li3P. Which best describes this ionic compound?
Answers
When lithium and phosphorus combine to form lithium phosphide, three lithium cations (Li+) combine with one phosphide anion (P₃-) to balance the charges and form a neutral compound, Li₃P.
What is Ionic compound?an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.
The correct description of the ionic compound lithium phosphide, with the chemical formula Li3P, is "Lithium ions have 1 positive charge, and phosphorus ions have 3 negative charges."
This is because lithium is a Group 1A element, which means it has one valence electron that it tends to lose in chemical reactions to form a cation with a charge of +1.
Phosphorus, on the other hand, is a Group 5A element, which means it has five valence electrons and tends to gain three electrons to form an anion with a charge of -3.
Thus, When lithium and phosphorus combine to form lithium phosphide, three lithium cations (Li+) combine with one phosphide anion (P₃-) to balance the charges and form a neutral compound, Li₃P.

Does anyone know how to prove that OAC and OBC are Congruent.
Answers
The first step is to see that sides OA, OC, OB are all equal because they are the radii of the circle. Knowing that those sides are equal means that we have isosceles triangles. That gives us that the base angles are the same.
In OAC, we can subtract 118 from 180 to give us 62 degrees for the 2 bases angles. This would make each angle 31 degrees.
In OBC, the base angles are already 31, leaving the other angle 118.
There we have all the angles the same and 2 sides the same.

Which of the following functions is graphed below?!?
Answers
The given graph is for a piecewise function consisting of two intervals:
(1) x ≤ 1 ⇒⇒⇒ the graph in this interval like a cubic function.
(2) x > 1 ⇒⇒⇒ the graph in this interval like a quadratic function
By comparing to the given options
The answer is option c.
Answer:
Option C is correct.
Explanation:
A piece-wise function is a function which is defined by multiple sub-functions, each sub-function applying to a certain interval of the main function's domain.
From the graph we can see that the function is made up of 2 pieces.
Solid dot means- Including
Open-dot means - not- including.
As we can see that the boundary lines are at x=1.
We have to look each line separately to determine each equation:
when [tex]x>1[/tex], it gives the function [tex]y=x^2+4[/tex] and
when [tex]x\leq 1[/tex], it gives the function [tex]y =x^3-2[/tex].
So, the piece-wise function is:
[tex]y=\left \{ {{x^3-2}, x\leq1 \atop {x^2+4}, x>1} \right.[/tex]
Which is the measure of the reference angle for 227 degrees
Answers
hope this helps<3
Algebraically, the reference angle for X is the smaller of (X mod 180°) and (-X mod 180°).
Here, that would be
.. min(227 mod 180, -227 mod 180)
.. = min(47, 133)
.. = 47 . . . . degrees
_____
"X mod 180" means you subtract the largest multiple of 180 that is smaller than X.
Then 227 mod 180 = 227 -180 = 47
and -227 mod 180 = -227 -(-360) = 133.

Find the Interest Earned.
Round to the nearest cent.
Amount = $980
Rate = 8%
Compounded = Quarterly
Time (Years) = 5
Answers
Principal Amount = P = $980
Interest rate = r = 8% = 0.08
Compounding periods = n = 4
Time = t = 5 years
Formula to be used for finding compounding amount:
[tex]A=P (1+ \frac{r}{n} )^{nt} [/tex]
Using the values in the formula, we get:
[tex]A=980 (1+ \frac{0.08}{4} )^{5*4} =1456.23[/tex]
Therefore, the amount compounded over a period of 5 years will be $1456.23
2)
Principal Amount = $980
Compounded Amount = $1456.23
Interest Earned = Compounded Amount - Principal Amount
Interest Earned = 1456.23 - 980 = $ 476.23
Therefore, $476.23 interest will be earned over a period of 5 years.
