Use the periodic compound interest formula to solve.
Suppose that $11,000 is invested at 5.8% compounded quarterly. Find the total amount of this investment after 6 years.
Answer:
$15,539.67
Step-by-step explanation:
Compound Interest Formula
[tex]\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}[/tex]
where:
A = final amountP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsedGiven:
P = $11,000r = 5.8% = 0.058n = 4 (quarterly)t = 6 yearsSubstitute the given values into the formula and solve for A:
[tex]\implies \sf A=11000\left(1+\frac{0.058}{4}\right)^{(4 \times 6)}[/tex]
[tex]\implies \sf A=11000(1.0145)^{24}[/tex]
[tex]\implies \sf A=15539.67451...[/tex]
Therefore, the value of the investment after 6 years will be $15,539.67 to the nearest cent.
A system of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the other equation?
A.y=-4x+5
B. Y=4x -5
C.2y=8x-10
D.-2y=-8x-10
answer :
A. y = – 4x + 5
Step-by-step explanation:
make y = 4x-5 equal to each of the answer choices and see if you get an answer
STEPS:
1.
make 4x - y = 5 into a y= equation
4x - y = 5 is y = 4x-5
2.
then make y = 4x-5 equal to each of the answer choices and see if you get an answer
A.
4x-5 = -4x+5
8x = 10
x = 10/8 = 5/4
yes, it has one solution
its also an intersecting line because
one line has 4x and the other has -4x
4x and -4x are slopes and opposite signs so
the lines are intersecting
B.
4x-5 = 4x-5
since they are the same on both sides of the equal sign they have
infinite solutions
they are also both the same line
C.
2y=8x-10 when simplified is y=4x-5
so its just like choice B
they are also both the same line
4x-5 = 4x-5 which is
0 = 0
since they are the same on both sides of the equal sign
infinite solutions
they are also both the same line
D.
-2y=-8x-10 when simplified is y=4x+5
4x-5 = 4x+5 when you work it out you get the answer
0 = 5
since when you solve the equation and get 0 = 5
that means its there is no solution
its also parallel line because both lines have 4x as a slope

a. l=r
b. jk=rs
c. k=s
d. j=s
e. kl=st

Answer:
b, c e
Step-by-step explanation:
A congruence statement lists corresponding parts in the same order. CPCTC says corresponding parts are congruent.
__
To see if any particular statement is consistent with CPCTC, identify the locations of the referenced parts in the congruence statement. If they match, the congruence is true
a. l = r ... jkl = rst . . . . not in the same place
b. jk = rs ... jkl = rst . . . . a match; true
c. k = s ... jkl = rst . . . . a match; true

A software company wants to get an idea of their customers' level of satisfaction with their software. To do so, they included a phone number on the packaging of their most recent software release, with the message, "If you have any concerns with the product, please call this number." Based on the overwhelmingly negative response they received from these calls, the company decided to stop selling the product.
What could be wrong with their decision?
A.
The phone system screened out certain positive comments because of a malfunction.
B.
The release of the software coincided with the spread of a virus which affected the performance of the program.
C.
The note on the package only told customers to call in the event that they had a concern, which could bias the results negatively.
D.
The customers were misinformed about the purpose of the program.
Answer:
C. The note on the package only told customers to call in the event that they had a concern, which could bias the results negatively.
Explanation:
Since customers were only told to call if they had concerns, all of the calls were about concerns or problems that they were having - meaning all of the calls were negative. However, they were never informed to call if they were happy or content with the product, meaning they were never informed of the people who had positive comments, only negative.

What is the solution to this system of equations? x + y = 2 and y - z = -3 and x + y - z = 0
Answer:
x = 3
y = -1
z = 2
Step-by-step explanation:
if x+y = 2, and x+y-z = 0, then we can substitute 2 for x+y. this means 2-z=0, meaning z=2. if y-z=-3, then y-2=-3, and y=-1. x+y=2 which means x-1=2 so x=3. plug in the values to check your answer.

When graphing inequalities:
< or > : draw a dashed line≤ or ≥ : draw a solid line< or ≤ : shade under the line> or ≥ : shade above the lineGiven inequality:
[tex]y-5 > 2x-10[/tex]
Rearrange the given inequality to make y the subject:
[tex]\implies y-5+5 > 2x-10+5[/tex]
[tex]\implies y > 2x-5[/tex]
Therefore, we need to draw a dashed line and shade above it.
To draw the line:
Replace the > with = to find two points on the line:
[tex]\implies y=2x-5[/tex]
[tex]x=0 \implies y=2(0)-5=-5 \implies (0,-5)[/tex]
[tex]x=3 \implies y=2(3)-5=1 \implies (3,1)[/tex]
Plot the two found points: (0, -5) and (3, 1)
As the inequality is y > 2x - 5
Draw a dashed straight line through the two points.Shade above the line.The inequality equation is solved and the solution is plotted on the graph
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
y - 5 > 2x - 10
On simplifying , we get
Adding 5 on both sides , we get
y > 2x - 5
where 2 is the slope and 5 is the the intercept
Now , let the first point be P ( 0 , -5 )
when x = 0 and y = -5
-5 > -5
And , the graph of the inequality is plotted
Hence , the inequality is solved

a) The volume of the cone.
b) The curved surface area of the cone.
Answer:
a) 301.6 cm³
b) 188.5 cm²
Step-by-step explanation:
The volume and lateral surface area of the cone can be found using the given dimensions with the given formulas. All that is needed is to substitute the appropriate values and do the arithmetic.
__
a) volumeThe volume is given by the formula ...
V = 1/3πr²h
The dimensions are given on the diagram: r = 6 cm, h = 8 cm. Using these values in the formula, we find the volume to be ...
V = 1/3π(6 cm)²(8 cm) = 96π cm³ ≈ 301.6 cm³
The volume of the cone is about 301.6 cm³.
__
b) areaThe lateral area of the cone is given by the formula ...
A = πrl
The dimensions are given on the diagram: r = 6 cm, l = 10 cm (the slant height). Using these values in the formula, we find the area to be ...
A = π(6 cm)(10 cm) = 60π cm² ≈ 188.5 cm²
The area of the curved surface is about 188.5 cm².
