Formula: Future value of annuity

In 20 years: $249,875

Total Interest: $99,875

Step-by-step explanation:

Use the formula for future value:

FV =

P = $6,000

r = 0.04

n = 1

t = 25

FV =

FV = $249,875

To find the total interest earned, first find the total value of the deposit payments:

$6,000 annual payments for 25 years = 6,000 • 25

= $150,000

(I copied that explanation from somewhere else so its a little messed up. I just couldn't explain it properly. Hope this helps!)

Account balance In 20 years is $249,875 and total interest earned is $99,875.

The FV formula assumes a constant rate of growth and a single up-front payment left untouched for the duration of the investment. The FV calculation can be done one of two ways, depending on the type of interest being earned.

We have,

P = $6,000

r = 0.04

n = 1

t = 25

We know the formula for future value

​FV= PV [tex](1 + r)^{n}[/tex].

where:

P=Investment amount

R=Interest rate

T=Number of years

According to the question​​

FV=$6,000×(1+0.04

FV = $249,875

To find the total interest earned, first find the total value of the deposit payments:$6,000 annual payments for 25 years = 6,000 × 25= $150,000

Total interest earned = FV - annually payment for 25 year = $249,875 - $150,000 = $99,875

Step-by-step explanation:

Please find the complete question in the attachment.

Cylinder volume V= 6 Cubes - inch  

The Formula:

[tex]\to V=\pi r^2 h= 6[/tex]

The (r and h ) is the radius and height of the cylinder and [tex]s(r)= \frac{12}{r}[/tex]represent the region of the mark in this r and h, and that is why  as can's radius gets bigger and larger, the label area gets closer to 0.

Answer:

A cylindrical can needs to have a volume of 6 cubic inches. A label is to go around the

side of the can. The function gives the area of the label in square inches

Answer:

12 side polygon

Step-by-step explanation:

Interior angle of n side regular polygon: = ((n-2)x180)/n

((n-2)x180)/n = 150

(n-2)x180 = 150n

180n - 360 = 150n

30n = 360

n = 12

check: (12-2)x180/12 = 150

Answer:

The polygon has 12 sides (a dodecagon).

Step-by-step explanation:

Angles in a Regular Polygon

A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that each angle (in a regular polygon) measures

[tex]\displaystyle \frac{180(n-2)}{n}[/tex]

We are given the interior angle of 150°, thus:

[tex]\displaystyle \frac{180(n-2)}{n}=150[/tex]

Multiplying by n:

[tex]\displaystyle 180(n-2)=150n[/tex]

Operating

[tex]\displaystyle 180n-360=150n[/tex]

Rearranging and simplifying:

[tex]\displaystyle 180n-150n=360[/tex]

[tex]\displaystyle 30n=360[/tex]

[tex]n=360/30=12[/tex]

n = 12

The polygon has 12 sides (a dodecagon).

An imposter took our life away

Now, we're stuck here to decay

Please let us get in

Don't lock us away

We're not like what you're thinking

We're poor little souls

Who have lost all control

And we're forced here to take that role!

Stuck in our little zone since 1987

Join us, be our friend or just be stuck and defend

----------------------------------------------

Explanation:

There are a lot of steps, so I broke things up into 3 sections or parts. The idea I'm applying is if the denominator is of the form [tex]a+\sqrt{b}[/tex], then multiplying top and bottom by [tex]a-\sqrt{b}[/tex] will rationalize the denominator. This is due to the difference of squares rule (step 3 of part 1). The following step shows squaring a square root has the two cancel out.

From that point, I simplified each square root and factored to cancel out a pair of '4's.

To expand out [tex](2-\sqrt{8})(4-\sqrt{12})[/tex], we can use either the FOIL method, the box method, or the distribution property. I used the distribution property.

(3-x)(3+x)

x^2-a^2 = (x-a)(x+a)

Answer:

One solution

Step-by-step explanation:

x - 4y = 6

-4y = 6 - x

-4y/-4 = 6/-4 -x/-4

y = -6/4 + -x/4

2x − 8y = 12

-8y = 12 - 2x

-8y/-8 = 12/-8 - 2x/-8

y = -12/8 + 2x/8

Graph "y = -6/4 + -x/4" and "y = -12/8 + 2x/8" to find how many solutions these lines have.

As shown below, it has only one solution.

D. (6+5)+(6+5)+6+5)

Step-by-step explanation:

i am. sure that D. is answer because it is repited three. times

Step-by-step explanation:

Coordinates of A≡(−1,3)

Coordinates of B≡(7,9)

Coordinates of C≡(15,-3)

The median through the vertex C will meet at the mid point of AB.

Coordinate of mid-point on AB=[(-1+7)/2 , (3+9)/2]= (3,6)

Now,

Length of median through vertex C= Distance between (15,-3) and (3,6)

Therefore,

Length of median = √(3-15)²+(6-(-3))²=√144+81=15unit

Hence the length of median through the vertx C is 15 units.

Answer: a = 47.3;

              p = 0.65

Step-by-step explanation: A power function is of the form [tex]y=ax^{p}[/tex] and passes through points (2,5) and (3,81), i.e.:

[tex]5=a.2^{p}[/tex]

[tex]81=a.3^{p}[/tex]

To determine the two unknows, solve the system of equations:

[tex]log5=log(a.2^{p})[/tex]

[tex]log81=log(a.3^{p})[/tex]

Using multiplication and power rules:

[tex]log5=loga+plog2[/tex]

[tex]log81=loga+plog3[/tex]

Giving values to constants:

0.7=loga+0.3p

2=loga+0.5p

This system of equations can be solved by subtracting each other:

[tex]-1.3=-0.2p[/tex]

p = 0.65

Substituting p into one of the equations above:

[tex]loga+0.5(0.65)=2[/tex]

[tex]loga=1.675[/tex]

[tex]a=10^{1.675}[/tex]

a = 47.3

The constants a and p of the power function which passes through points (2,5) and (3,81) are 47.3 and 0.65, respectively.

Answer:

It would take her 90 minutes to run 10 miles.

Step-by-step explanation:

First you should divide 54 by 6 and you'll get 9. So it takes her 9 minutes to run 10 miles (which is physically impossible). You multiply 9 times 10 and get 90.

Answer:

x = 37

y = 79

Step-by-step explanation:

Remark

We are going to go through an extensive discussion of the value of x. The value for y is found exactly the same way.

Top diagram.

The top diagram establishes the fact that if any two points are on the major arc of the circle whose center is 0, then the vertex of the of the two angles so formed are equal. The end points of these two angles must be established by the endpoints of the chord A and B.

Put in much simpler language.

<ACB = <AC'B

The end points of the angles are A and B of the Chord AB.

The Vertex of the angles are both on the major arc of the circle. These two are C and C'

Bottom Diagram

The idea here is to find the value of C. If we do that, then we know what x is in the diagram you provided.

Draw diameter COA       Construction

< CAB = 90                      Any vertex (C) on circumference with diameter endpoints (A & C) = 90

<CAT_1 = 90                   A diameter always meets a tangent at 90o

<BAT_1 = 37                   Given

<CAB = 90-37                  <CAB and <BAT_1 are complementary

<ACB = 37                       A right triangle's acute angles are complementary.

<ACB = x = 37o              See top diagram
