If you invest $3900 at a 7.84 simple annual interest rate, approximately how long will it take for you to have a total of $10,000
It would take approximately 19.94 years to accumulate a total of $10,000 from an initial investment of $3,900 at a simple annual interest rate of 7.84%.
To determine how long it will take to accumulate $10,000 from an initial investment of $3,900 at a simple annual interest rate of 7.84%, we can use the formula for simple interest:
I = Prt
where I is the interest earned, P is the principal or initial investment, r is the annual interest rate as a decimal, and t is the time in years.
To find the time required to reach a final amount of $10,000, we can rearrange the formula:
t = (I/P) / r
First, we need to calculate the interest earned on the initial investment:
I = Prt
I = (3900)(0.0784)t
I = 305.76t
To reach $10,000, we need to earn an additional $10,000 - $3,900 = $6,100 in interest. So we can set up the equation:
6100 = 305.76t
Solving for t, we get:
t = 6100 / 305.76
t ≈ 19.94 years

A business has 40,000 to spend on advertising in an upcoming sale. The money is to be divided between television (x), radio (y) and newspapers (z). The business manager has decided to spend three times as much money on television as on radio. The manager has also decided to spend 8000 less on radio advertising than on newspapers. Find out, using matrix inversion method, the total amount divided between television, radio and newspapers.
Okay, let's break this down step-by-step:
* The business has $40,000 total to spend on advertising
* Some will go to TV (x), some to radio (y), and some to newspapers (z)
* 3 times as much will go to TV as radio, so x = 3y
* They will spend $8,000 less on radio than newspapers, so y = z - 8,000
* We have:
x = 3y (1)
y = z - 8,000 (2)
x + y + z = 40,000 (3)
To solve this using matrix inversion:
1) Turn the equations into a matrix:
3 1 0 y
1 -1 1 z
1 1 1 x
2 0 40,000
2) Invert the matrix:
0.3333 0.3333 0.3333
-0.25 0.75 0
0.125 0.125 0.750
3) Plug in the values from (2) and (3):
y = 0.3333(z - 8,000)
x = 0.125z + 0.125(40,000 - z)
4) Solve for z, the amount for newspapers. We get:
z = 40,000 * (0.75) = 30,000
5) Plug z = 30,000 back into the other equations:
x = 0.125 * 30,000 + 0.125 * 10,000 = 12,000
y = 0.3333 * (30,000 - 8,000) = 8,000
z = 30,000
So in total:
TV (x) = $12,000
Radio (y) = $8,000
Newspapers (z) = $30,000

A small college has 10 professors in the Mathematics Department. The department teaches pure math, applied math, and
statistics. Professors are apportioned using Hamilton's apportionment method, according to the number of majors in each
field. There are 4 pure math majors, 12 applied math majors, and 12 statistics majors.
If the department receives a grant to hire 1 more professor, will the Alabama paradox occur? Why or why not?
Answer:
Yes, because while the total number of professors increases, the number of pure math professors decreases.
Step-by-step explanation:
Using Hamilton's method:
pure math 4/28 = 0.142857
applied math 12/28 = 0.42857
statistics = 12/28 = 0.42857
10 × 0.142857 = 1.42857
10 × 0.42857 = 4.2857
10 × 0.42857 = 4.2857
numbers of professors:
pure math 1
applied math 4
statistics 4
total 9
Add 1 to pure math
Final original numbers of professors using Hamilton's method
pure math 2
applied math 4
statistics 4
total 10
Add 1 professor to department.
11 × 0.142857 = 1.5714
11 × 0.42857 = 4.71428
11 × 0.42857 = 4.71428
numbers of professors:
pure math 1
applied math 4
statistics 4
total 9
Add 1 to applied math and 1 to statistics
Final new numbers of professors using Hamilton's method
pure math 1
applied math 5
statistics 5
total 11
Despite the addition of 1 professor to the department, the field of pure mathematics went from 2 professors to 1 professor. This is an example of the Alabama paradox.
Answer: Yes, because while the total number of professors increases, the number of pure math professors decreases.
If you transform y = 2x2 into y = 10x2, which option below describes the effect of this transformation on the graph of the quadratic function along the y-axis?
(b) The transformation stretches the graph by a factor of 5 describes the effect of this transformation on the graph of the quadratic function along the y-axis.
The transformation from y = 2x² to y = 10x² changes the coefficient of the x² term from 2 to 10. This change in the coefficient affects the vertical scaling of the graph of the quadratic function along the y-axis. When we multiply the entire function by a constant, it causes a vertical stretch or compression of the graph depending on the magnitude of the constant.
In this case, the transformation stretches the graph along the y-axis by a factor of 5 since 10 is 5 times greater than 2. This means that the vertical distance between the points on the graph of the function is now 5 times greater than before the transformation.
Therefore, the correct option is (b) - The transformation stretches the graph by a factor of 5.
Correct Question :
If you transform y = 2x2 into y = 10x2, which option below describes the effect of this transformation on the graph of the quadratic function along the y-axis?

Goran used 2 1/2 gallons of gas on Sunday and 1/4 gallons of gas on Monday. How many gallons did he use on the two days combined? Write your answer as a mixed number in simplest form.
Okay, here are the steps to solve this problem:
* Goran used 2 1/2 gallons on Sunday
* Goran used 1/4 gallons on Monday
* So on Sunday he used 2 1/2 gallons and on Monday he used 1/4 gallons
* To find the total gallons used on both days:
** 2 1/2 gallons (used on Sunday)
+ 1/4 gallons (used on Monday)
= 2 3/4 gallons (total used on both days)
So in simplest form as a mixed number, the total gallons Goran used on both days combined is:
2 3/4
[tex]\sf 2\dfrac{3}{4}.[/tex]
Step-by-step explanation:To find this answer, all we need to do is add up both of the fractions, that will give us the total amount of gas used on both days. Let's calculate:
1. Convert the first fraction into an improper fraction.[tex]\sf 2\dfrac{1}{2} =\\ \\\dfrac{2}{2}+\dfrac{2}{2}+\dfrac{1}{2}=\dfrac{5}{2}[/tex]
2. Write the sum of the two fractions that express the daily gas consumption.[tex]\sf \dfrac{5}{2}+ \dfrac{1}{4}[/tex]
3. Using the formula from the attached image, rewrtite the fraction addition.[tex]\sf \dfrac{5}{2}+ \dfrac{1}{4}= \dfrac{(5*4)+(2*1)}{2*4}= \dfrac{(20)+(2)}{8}=\dfrac{22}{8}=\dfrac{11}{4}[/tex]
4. Convert the resulting improper fraction into a mixed fraction.[tex]\sf \dfrac{11}{4}=2.75[/tex]
Take the entire part of the decimal number (2) and write it as the whole number on the mixed number. Also, since the fraction has a denominator of 4, a unit of this fraction would be 4/4, then, the 2 units that we're going to express as a whole number would be 8/4. So, subtract 8/4 from 11/4 and express in the following fashion:

Use separation of variables to find the general solution to the following differential equation.
Therefore, the general solution to the differential equation is
Y = e⁽ˣ⁾2+X+C) - 1 or Y = -e⁽ˣ⁾2+X+C) - 1
What exactly is a different equation?A differential equation is an equation that connects the derivatives of one or more unknown functions. It is an equation that uses the derivatives of a function or functions, in other words. Many physical processes, including the motion of objects under the influence of forces, the movement of fluids, and the spread of disease, are modelled using differential equations in science and engineering. Ordinary differential equations (ODEs) and partial differential equations (PDEs) are the two primary categories of differential equations.
To solve this differential equation using separation of variables, we first need to separate the variables Y and X on opposite sides of the equation:
dY / (Y + 1) = (2X + 1) dX
Following that, we incorporate both sides of the problem:
∫ dY / (Y + 1) = ∫ (2X + 1) dX
The integral on the left side can be evaluated using the substitution
u = Y + 1 and du = dY:
ln|Y + 1| = ∫ dY / (Y + 1) = ln |u| + C1
where C1 is the constant of integration.
The integral on the right side can be evaluated using the power rule of integration:
∫ (2X + 1) dX = X² + X + C2
where C2 is another constant of integration.
Putting these results together gives the general solution to the differential equation:
ln|Y + 1| = X² + X + C
where C = C1 + C2 is the combined constant of integration.
To solve for Y, we exponentiate both sides of the equation:
|Y + 1| = e⁽ˣ⁾2+X+C)
Taking into account the absolute value, we have two cases:
Case 1: Y + 1 = e⁽ˣ⁾2+X+C)
Y = e⁽ˣ⁾2+X+C) - 1
Case 2: Y + 1 = -e⁽ˣ⁾2+X+C)
Y = -e⁽ˣ⁾2+X+C) - 1
Therefore, the general solution to the differential equation DY/DX=(Y+1)(2X+1) is:
Y = e⁽ˣ⁾2+X+C) - 1 or Y = -e⁽ˣ⁾2+X+C) - 1

First, you can convert -1 5/7 to an improper fraction by multiplying the denominator with the whole number, then add the answer to the numerator. Like this:
7 × 1 = 7
7 + 5 = 12
12 will be your numerator and 7 will be your denominator. When you're done converting, bring down the negative sign. The fraction should be:
-12/7
Now, since -1 5/7 is -12/7, we can divide.
To divide, we can use, KCF (Keep, Change, Flip)
First, keep -12/7.
Second, change division to multiplication.
Third, flip 1/2.
Your problem will be set up like:
-12 /7 × 2/1
Now, we can solve. Multiply both the numerator AND the denominator. Since you're multiplying, you don't have to change the denominator to match each other. The answer will be:
-24 / 7
However, this fraction is improper. We can use long division to make this fraction proper.
Divide 24 and 7. You'll get 3, with a remainder of 3.
The remainder will be the new numerator and the answer will be the whole number.
3 - Remainder (Whole Number)

If f(x)=2x^2+3 and g(x)=x^2-7, find (f-g)(x).
Answer:
To find (f-g)(x), we need to subtract g(x) from f(x):
(f-g)(x) = f(x) - g(x)
Given f(x) = 2x^2 + 3 and g(x) = x^2 - 7, we can substitute these expressions into the formula above:
(f-g)(x) = f(x) - g(x)
= (2x^2 + 3) - (x^2 - 7)
Now we simplify by combining like terms:
(f-g)(x) = 2x^2 + 3 - x^2 + 7
= x^2 + 10
Therefore, (f-g)(x) = x^2 + 10.
Answer: To find (f-g) (x)
(f-g)(x)= f(x) -g(x)
Given f(x) = 2x^2 + 3 and g(x) = x^2 - 7, we can substitute these expressions into the formula above:
(f-g)(x) = f(x) -g(x)
=(2x^2+3) - (x^2-7)
Now we can simplify the equation:
(f-g)(x)= 2x^2+3 - x^2+7
= x^2 + 10
Hence, (f-g)(x) = x^2+10

Ax² + Bx + C = 0, where A, B, and C are constants.
Given that the situation is expressed by the equation, w² + 6w = 112, we can expressed this in standard form as follows:
w² + 6w = 112
Subtract 112 from both sides:
w² + 6w - 112 = 112 - 112
w² + 6w - 112 = 0
The standard form is therefore, w² + 6w - 112 = 0, and the value of b is equal to 6.

You invest $1850 in an account paying 5.2% interest compounded daily. What is the account's effective annual yield?
Answer: 5.36%
Step-by-step explanation:
The formula for the effective annual yield (EAR) when the interest is compounded daily is given by:
(1 + r/365)^365 - 1
where r is the annual interest rate.
In this case, the annual interest rate is 5.2% or 0.052. Substituting this value into the formula, we get:
(1 + 0.052/365)^365 - 1 = 0.0536
Multiplying this value by 100 gives the effective annual yield as a percentage:
0.0536 x 100 = 5.36%
Therefore, the effective annual yield of the account is 5.36%.

An annual salary of K31 600 had an increase of 8%. What is the new salary amount? Working out:
To calculate the new salary amount, we need to add the increase to the original salary.
The increase in salary is 8% of the original salary, which is:
8/100 x K31 600 = K2 528
So, the new salary amount is:
K31 600 + K2 528 = K34 128
Therefore, the new salary amount is K34 128.
To find the new salary after an 8% increment, first find what 8% of the original salary is by multiplying it by 0.08. Add this amount to the original salary to calculate the new salary, which is K34 128.
Explanation:In order to calculate the new salary after an 8% increment, you first need to figure out how much 8% of the original salary is and then add this to the original salary. So first, remember that 'percent' means 'per hundred', so to calculate 8% of K31 600, you would multiply 31 600 by 0.08 (which is the decimal equivalent of 8%). This gives you K2 528. Then you add this amount to the original salary to get the new salary. Therefore, K31 600 + K2 528 equals to a new salary of K34 128.

answer pls!! quick asp
Answer:
ZR = 145°
Step-by-step explanation:
the secant- secant angle ZAR is half the difference of the measures of the intercepted arcs , that is
∠ ZAR = [tex]\frac{1}{2}[/tex] ( ZR - KV )
30 = [tex]\frac{1}{2}[/tex] (5x + 10 - (3x + 4) ) ← multiply both sides by 2 to clear the fraction
60 = 5x + 10 - 3x - 4
60 = 2x + 6 ( subtract 6 from both sides )
54 = 2x ( divide both sides by 2 )
27 = x
Then
ZR = 5x + 10 = 5(27) + 10 = 135 + 10 = 145°
The formula for the volume of a right circular cylinder is V=πr2h. If r=2b and h=5b+3, what is the volume of the cylinder in terms of b?
The volume of the cylinder in terms of b is expressed as: (20b³ + 12b²)π cubic units.
What is the Volume of a Cylinder?Where r represents the radius of a cylinder and h represents its height, the volume of the cylinder can be calculated using the formula:
V = πr²h.
Given the following:
Radius (r) = 2b
Height (h) = 5b + 3
Volume (V) = π * (2b)² * (5b + 3)
Volume (V) = π * 4b² * (5b + 3)
Volume (V) = π * 20b³ + 12b²
Volume (V) = (20b³ + 12b²)π cubic units

is x^3 an exponential function
y = |x - 5| + |x + 5| if x >5
Answer:
y = 2x
Step-by-step explanation:
You want the simplified form of y = |x -5| +|x +5| if x > 5.
Turning pointsThe graph of the whole function will have turning points where the absolute value expressions are 0:
x -5 = 0 ⇒ x = 5
x +5 = 0 ⇒ x = -5
For values of x > 5, we are concerned with that portion of the graph that is to the right of both of these turning points. Hence, both absolute value expressions are positive and unchanged by the absolute value bars.
y = (x -5) +(x +5) . . . . . . if x > 5
y = 2x . . . . . . . . . . . . . . collect terms
The simplified function is y = 2x.
