Use the domain and range of each of the following relations to determine which is a function.
A. {3,7,-7,9}
B. { (3,9), (7,-4), (-7,7) }
C. { (3,9), (7,-4), (-7,7) }
D. { (3,9), (7,-4), (7,6), (-7,7) }
Answer:
B
Step-by-step explanation:
i took a test with this question
We want to see which one of the given relations is a function.
The correct options are:
B and C.
To see this, we first need to define what a function is.
A function is a relationship that maps elements from one set, the domain, into another set, the range.
Such that each element in the domain can be mapped into only one element on the range.
The standard notation to these relations is (x, y).
This means that x, from the domain, is being mapped into y, from the range.
Now let's analyze the given options:
A) {3,7,-7,9}
This is just a set of values, no relation there, so this is not a function.
B) { (3,9), (7,-4), (-7,7) }
Here we have a relation, and we can see that each element on the domain is being mapped into only one element from the range, so this is a function.
C) { (3,9), (7,-4), (-7,7) }
This is the exact same set as the one on B.
D) { (3,9), (7,-4), (7,6), (-7,7) }
Here we can see that the element x = 7 is mapped into two different values, so this is not a function.
Then the options that represent functions are B and C.

A contaminant is found in a solution at a level of 3/500%. What fraction of the solution is this
Answer:3/5
Step-by-step explanation:
First we change 500% to fractions
Changing percentage to fraction is dividing the number by 100
500% = 500/100
Putting this we get 3/(500/100)
Then when a number is being divided by a fraction, to get the answer, we multiply the number by the inverse of the fraction
3/(500/100) = 3 x 100/500 = 300/500 = 3/5
If contaminant is found in a solution at a level of 3/500%. Then 3/5 is fraction of the solution
What is Fraction?A fraction represents a part of a whole.
Given,
A contaminant is found in a solution at a level of 3/500%
Let us convert five hundred percentage to a fraction.
500% is converted to fraction by dividing 500/100
So let us divide three by 500/100
3/ (500/100)
When a fraction is divided with another fraction, then the denominator is multiplied inversely with numerator
3×100/500
=300/500
3/5
Hence if contaminant is found in a solution at a level of 3/500%. Then 3/5 is fraction of the solution

A certain type of bacteria increases continuously at a rate proportional to the number present. if there are 500 present at a given time and 1,000 present 2 hours later, how many hours (from the initial given time) will it take for the numbers to be 2,500
The number of hours from the initial given time that will take for the bacteria to grow to 2500 number is 4.64 hours approx.
How to calculate the instantaneous rate of growth of a function?Suppose that a function is defined as;
[tex]y = f(x)[/tex]
Then, suppose that we want to know the instantaneous rate of the growth of the function with respect to the change in x, then its instantaneous rate is given as:
[tex]\dfrac{dy}{dx} = \dfrac{d(f(x))}{dx}[/tex]
Assuming that the bacterial growth can be approximated by a continous and differentiable function y = f(x), where x represents the number of hours spent from the initial time, we're given that:
[tex]\dfrac{dy}{dx} \propto y[/tex]Supposing the proportionality constant be k, then we get:
[tex]\dfrac{dy}{dx} = ky[/tex]
Solving this differential equation, we get:
[tex]\dfrac{dy}{y} = kdx\\\\\text{Integrating both the sides without limits}\\\\\int \dfrac{dy}{y} = \int x dx\\\\\ln(y) + \ln(c) = kx\\\\\ln(yc) =kx\\ yc = e^{kx}\\y = \dfrac{e^{kx}}{c}[/tex]
where ln(c) represents the integration constant. (we took ln(c) because, firstly, ln's range is whole real number (which gives us the access to use it as integration constant), and secondly that it can merge with ln(y) to simplify the work)
Since we're given that:
At x = t (for some value of t in hours), we're given that y = 500,
and for x = t+2, y = 1000,
so we get two equations as:
[tex]\\500 = \dfrac{e^{kt}}{c}\\\\1000 = \dfrac{e^{k(t+2)}}{c}\\[/tex]
Thus, we get:
[tex]\dfrac{e^{kt}}{500} = \dfrac{e^{k(t+2)}}{1000} \\\\kt = \ln(0.5) + k(t+2)\\\\k = \dfrac{-\ln(0.5)}{2}} \approx 0.3465[/tex]
Thus, we get:
[tex]\\500 = \dfrac{e^{kt}}{c} \\\\c = \dfrac{e^{0.3465t}}{500}[/tex]
Thus, we get:
[tex]y = \dfrac{e^{0.3465x}}{\dfrac{e^{0.3465t}}{500}} = 500e^{0.3465(x-t)[/tex]
Let from the initial given time t, it takes h hours more for bacterias to be 2500, then we get:
[tex]2500 = 500 \times e^{0.3465 (t+h - t)}\\0.3465(h) = \ln(5)\\\\h = \dfrac{\ln(5)}{0.3465} = 4.644 \: \rm hours \: approx.[/tex]
Thus, the number of hours from the initial given time that will take for the bacteria to grow to 2500 number is 4.64 hours approx.

If the length of one base of a trapezoid is 5, the length of the other base is 2x + 7, and the length of the midsegment is 6x – 24, what is the value of x? Show equations and all work that leads to your answer.
Answer:
x = 6
Step-by-step explanation:
The midsegment of a trapezoid is the line parallel to the parallel sides of the trapezoid, which connects the midpoints of the non-parallel sides.
The length of the midsegment of the trapezoid is half the sum of the length of the parallel sides.
i.e,
Length of the midsegment = (1/2) *(Length of base1 + Length of base2)
6x - 24 = (1/2) * (5 + 2x + 7)
12x - 48 = 2x + 12
10x = 60
x=6

Orlando invested $16,000 in an eight-year CD bearing 6.5% simple annual interest, but needed to withdraw $3,500 after five years. If the CD’s penalty for early withdrawal was one year’s worth of interest on the amount withdrawn, when the CD reached maturity, how much less money did Orlando earn total than if he had not made his early withdrawal? a. $227.50 b. $682.50 c. $910.00 d. $455.00
Answer:
Therefore, the correct option is OPTION C.
Step-by-step explanation:
If Orlando had not made his early withdrawal, the amount of money he would have earned is:
F = 0.065($16,000)(8) = $8.320
Given that he withdraw $3500, he now earns:
F1 = (0.065)($16,000)(5) + ($12,500)(0.065)(3)
F1 = $5200 + $2437.5 = $7637.5
And now we have to take into acount the year of penalty, which is one year’s worth of interest on the amount withdrawn.
Penalty= $3500(0.065)(1) = $227.5
So the total money he earns now is: $7637.5 - $227.5 = $7410
Then, the amunt of money he could have earn but he didn't is:
Money = $8.320 - $7410 = $910
Therefore, the correct option is OPTION C.

208
Answer:
P = 124 inches
Step-by-step explanation:
We will need to use the Pythagorean theorem to find the bottom of the rectangle.
a^2 + b^2 = c^2
14^2 + b^2 = 50^2
196 + b^2 = 2500
Subtract 196 from each side
b^2 = 2500 -196
b^2 =2304
Take the square root of each side
sqrt(b^2) =sqrt(2304)
b=48
The perimeter is equal to
P =2(l+w)
P =2(14+48)
= 2(62)
= 124

What is the length of the midsegment of the trapezoid made by the vertices A(0, 5), B(3, 3), C(5, -2) and D(-1, 2). Show equations and all work that leads to your answer.
Answer:
[tex]\frac{3\sqrt{13} }{2}[/tex]
Step-by-step explanation:
First we have to identify the parallel sides of the trapezium.
We know that the slopes are equal for parallel lines.
Slope of (x₁,y₁) and (x₂,y₂) is given by
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Slope of AB:
[tex]m_{AB} = \frac{3-5}{3-0}=-\frac{2}{3}[/tex]
Slope of BC:
[tex]m_{BC} = \frac{-2-3}{5-3}=-\frac{5}{2}[/tex]
Slope of CD:
[tex]m_{CD} = \frac{2+2}{-1-5}=-\frac{4}{6}=-\frac{2}{3}[/tex]
Slope of DA:
[tex]m_{DA} = \frac{2-5}{-1-0}=3[/tex]
We see that the slopes of AB and CD are equal, so, AB and CD are the parallel sides.
The length of the midsegment = (1/2)*(length of base1 + length of base2 )
Length of the bases can be calculated using distance formula,
[tex]d= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
AB = [tex]\sqrt{(3-0)^{2}+(3-5)^{2}}= \sqrt{9+4} =\sqrt{13}[/tex]
CD = [tex]\sqrt{(-1-5)^{2}+(2+2)^{2}}= \sqrt{36+16} =\sqrt{52}=2 \sqrt{13}[/tex]
Length of the midsegment = (1/2) (√13 + 2√13) =3√13/2

In △ABC, AD and BE are the angle bisectors of ∠A and ∠B and DE ║ AB . Find the length of DE if perimeter of ABDE is 30 cm and AB = 12 cm
Answer:
DE = 6 cm
Step-by-step explanation:
Let DE = x cm.
Since DE is parallel to AB therefore by the alternate interior angles theorem, m∠BAD = m∠ADE and m∠ABE = m∠DEB ............(1)
As AD is an angle bisector of ∠A, therefore m∠EAD = m∠DAB ; Since BE is an angle bisector of ∠B ⇒ m∠ABE = m∠EBD.
Therefore, from (1) We get , m∠EAD = m∠ADE and m∠EBD = m∠BED.
So, the triangles ADE and EDB are then isosceles with AE = ED and ED = DB.
So AE = DE = DB = x, and since the perimeter of ABDE is 30 cm, then
12 + x + x + x = 30
⇒ 12 + 3x = 30
⇒ x = 6
Hence, the length of DE is 6 cm.
Answer:
DE=6cm
Step-by-step explanation:
Let x=DE, since AB║DE, therefore ∠BAD=∠ADE and ∠ABE=∠BED. (1)
Also, we are given that AD is the angle bisector of ∠A and BE is the angle bisector of ∠B,
Therefore, ∠EAD=∠DAB and ∠ABE=∠EBD (2)
From (1) and (2), ∠EAD=∠ADE and ∠EBD=∠BED
⇒The ΔADE and ΔEDB then becomes the isosceles triangle with AE=Ed and ED=DB (Sides opposite to equal angles are always equal)
Therefore, AE=DE=DB=x
We are given that the perimeter of ABDE is 30 cm, therefore,
Perimeter of ABDE= sum of all the sides of ABDE
⇒30=AB+BD+DE+AE
⇒30=12+3x
⇒30-12=3x
⇒x=6cm
Therefore, the length of DE= 6cm
Identify the value of p. Give your answers in simplest radical form. HELP PLEASE!!
Answer:
C
Step-by-step explanation:
using the cosine ratio to find p
cos 45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{p}[/tex]
cross- multiplying gives
p × cos45° = 6 → [ cos 45° = [tex]\frac{1}{\sqrt{2} }[/tex]]
p × [tex]\frac{1}{\sqrt{2} }[/tex] = 6
multiply both sides by [tex]\sqrt{2}[/tex]
⇒ p = 6[tex]\sqrt{2}[/tex] ( third option on list )
To determine the value of p in simplest radical form, solve the equation by simplifying the denominator and taking the square root of both sides. The value of p is 2.
Explanation:To identify the value of p, we need to solve the equation and simplify it to the simplest radical form. Let's start by simplifying the denominator and expressing it as a perfect square.
Next, we can take the square root of both sides of the equation to eliminate the square. This will help us isolate p. Once we do that, we can solve for p by getting rid of the square root on the left side of the equation. After simplifying, we find that p = 2.
So, the value of p is 2.
A bond purchased at $500.00 now has a value of $650.00 what is the percent increase of its value?
Answer: A bond purchased at $500.00 now has a value of $650.00 what is the percent increase of its value?
To make it simple for you, the final ANSWER is a 30% increase, due to the fact that taking $500.00 and multiplying that by 0.3 gives you 150, which you add on to 500, giving you 650. Hope that helps!
Answer: The required percent increase in the bond's value is 30%.
Step-by-step explanation: Given that a bond purchased at $500.00 now has a value of $650.00.
We are to find the percent increase of the value of bond.
According to the given information, we have
Purchasing value of the bond = $500.00
and
present value of the bond = $650.00.
So, increase in the value of the bond = $(650.00 - 500.00) = $150.00.
Therefore, the percent increase of the bond's value is given by
[tex]\dfrac{150.00}{500.00}\times 100\%=\dfrac{3}{10}\times 100\%=30\%.[/tex]
Thus, the required percent increase in the bond's value is 30%.
