Answer:

394,898

Step-by-step explanation:

9.8% = 0.098

0.098x = 38700

Divide both sides by 0.098

x = 38700/0.098

x = 394,897.9591836735

Rounding

x = 394,898

Given:

First 10 term of a geometric series are:

[tex]\dfrac{16}{25}+\dfrac{8}{5}+4+10+...+a_10[/tex]

To find:

The expression that  represents the sum of the series.

Solution:

The first term of the given geometric series is:

[tex]a_1=\dfrac{16}{25}[/tex]

The common ratio of the given geometric series is:

[tex]r=\dfrac{a_2}{a_1}[/tex]

[tex]r=\dfrac{\dfrac{8}{5}}{\dfrac{16}{25}}[/tex]

[tex]r=\dfrac{8}{5}\times \dfrac{25}{16}[/tex]

[tex]r=\dfrac{5}{2}[/tex]

The sum of first n terms of a geometric sequence is:

[tex]S_n=\dfrac{a_1(1-r^n}{1-r}[/tex]

Where r is the common ratio.

Putting [tex]a_1=\dfrac{16}{25},r=\dfrac{5}{2},n=10[/tex] in the above formula, we get

[tex]S_{10}=\dfrac{16}{25}\left(\dfrac{(1-(\dfrac{5}{2})^{10}}{1-\dfrac{5}{2}}\right)[/tex]

Therefore, the correct option is C, i.e., [tex]\dfrac{16}{25}\left(\dfrac{(1-(\dfrac{5}{2})^{10}}{1-\dfrac{5}{2}}\right)[/tex].

Answer:

-10

Step-by-step explanation:

t3 = a1 + (n - 1)*d

t3 = a1 + (3 -1)*d

2 = a1 + 2d

t17 = a1 + (n - 1)*d

-40 = a1 + 16d                Put the first condition underneath and subtract

  2 = a1 + 2d

-42 = 14 d

d = - 3

2 = a1 + 2*(-3)

2 = a1 - 6                      Add 6 to both sides

2 + 6 = a1

a1 = 8

Now you want the 7th term

t7 = a1 + (n - 1)*d

t7 = 8 + (7 - 1)*d

t7 = 8 + 6*(-3)

t7 = 8 - 18

t7 = - 10

[tex]x^{2}[/tex]+14x-32 [tex]units^{2}[/tex]

Step-by-step explanation:

a basketball court is a rectangle, therefore its area is length x width.

the length given is (x+16)

the width given is (x-2)

substitute into the rectangular area equation:

length x width = (x+16)(x-2)= [tex]x^{2}[/tex]+14x-32

specific units (e.g. centimetres, meters, feet, etc) were not given so use the term 'units', and because we are dealing with area, use [tex]units^{2}[/tex].

therefore the answer is, [tex]x^{2}[/tex]+14x-32 [tex]units^{2}[/tex].

Step-by-step explanation:

5 lbs. of organic red potatoes cost $6.00. The price per pound of organic red potatoes is $1.20.

To find the price per pound of organic red potatoes, we can divide the total cost by the weight in pounds.

Price refers to the monetary value or amount that is assigned or charged for a product, service, or commodity. It represents the cost or value that a buyer is required to pay in exchange for obtaining or acquiring something.

Given that 5 lbs. of organic red potatoes cost $6.00, we can set up the following equation:

Price per pound = Total cost / Weight in pounds

Price per pound = $6.00 / 5 lbs.

Dividing $6.00 by 5 pounds gives us:

Price per pound = $1.20

Therefore, the price per pound of organic red potatoes is $1.20.

Balance after 8 years is $2,306.86 at an interest rate of 15 % compounded yearly.

Compound interest simply refers to the fact that an investment, loan, or bank account's interest accrues exponentially over time as opposed to linearly over time. The word "compound" is crucial here.

given, Melissa opened a savings account and deposited $700.00 as principal. The account earns 15% interest

from the general formula of compound interest

A = [tex]P(1 + r/n)^{nt}[/tex]

where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years.

Given, P = 700$

r = 15%

t = 8 years

A = 700(1 + 15/100)⁸

A = 2306.86$

We are given:

Coordinates of center: (2,8)

Radius of circle: 3 units

Finding equation of the circle:

We know that the general form of a circle is:

(x-h)² + (y-k)² = (radius)²

where h is the x-coordinate of the center and k is the y-coordinate

replacing with the given values, we get:

(x-2)² + (y-8)² = (3)²

The width and the length that gives the largest possible areas are 75 meters by 37.5 meters

From the question, we have the following parameters that can be used in our computation:

Number of warehouses = 4

Perimeter of fence = 300 meters

Represent the width with x and the length with y

So, we have the following equations

Area = 4xy

Perimeter = 2(4x + y)

Substitute the known values in the above equation, so, we have the following representation

2(4x + y) = 300

Divide both sides by 2

2x + y = 150

Make y the subject

y = 150 - 2x

Substitute y = 150 - 2x in Area = 4xy

A = 4x(150 - 2x)

This gives

A = 600x - 8x²

Differentiate and set to 0

600 - 16x = 0

So, we have

16x = 600

Divide by 16

x = 37.5

Recall that

y = 150 - 2x

So, we have

y = 150 - 2 x 37.5

Evaluate

y = 75

Hence, the dimensions are 75 meters by 37.5 meters

Answer:

The answer is 1367.31 not sure but try it

The amount will be $1367.3 after 9 years.

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.

Given that, p = 800, r = 6%, t = 9 year, we need to find the amount if the principal is compounded quarterly,

A = P(1+r)ⁿ

Since, the principal is compounding quarterly, the formula will become,

A = P(1+r/4)⁴ⁿ

A = 800(1+0.06/4)³⁶

A = 800(1.015)³⁶

A = 1367.3

Hence, the amount will be $1367.3 after 9 years.

Answer: 24 units.

Step-by-step explanation: To find the perimeter of a triangle, you need to add the length, width, and hypotenuse. The length and width are provided, but we need to find the hypotenuse of the triangle. To do this, we need to use the Pythagorean Theorem.

The Pythagorean Theorem is basically a^2 + b^2 = c^2 where a and b are the legs of the triangle and c is the hypotenuse (also known as the triangle's longest side). However, whatever answer you get needs to be square-rooted, which is your complete answer. Let's say that the side that's 6 units is leg a and the side that's 8 units is leg b.

6^2 + 8^2 = c^2

36 + 64 = 100

√100 = 10.

Now that we know the hypotenuse, we can add it to our other two sides.

6 + 8 + 10 = 24.

Therefore, 24 is your answer.

The  largest amount of money they can borrow is $$276.268.65

The main formula used in this problem is the Present Value of an annuity Formula:

P = R[1-(1+i)⁻ⁿ]/i

Where;

The maximal monthly payment that Bethany and Samuel can afford is $1,500.

The best interest rate is %5.1 annually, and they want to sign a 30-year mortgage.

This implies that

R=1,500

t=30

r=%5.1 = 5.1 /100 = 0.051

m=12, because they make the payments monthly

i=r/m=0.051/12=0.00425

n=mt = 12*30=360

That is,

i) they will make 360 monthly payments,

ii) the largest amount of money they can borrow can be found using the formula:

P = R[1-(1+i)⁻ⁿ]/i

Substituting the known values:

P = 1500[1-(1+0.00425)⁻³⁶⁰]/0.00425
