The future value in 13 years when compounded continuously is; $18183.25

Continuous compounding is defined as the process of calculating interest and reinvesting it into an account's balance over an infinite number of periods.

The formula for continuous compounding is;

V = Pe^(rt)

where;

V is the value of the account in t years

P is the principal initially invested

e is the base of a natural logarithm.

r is the rate of interest

We are given;

P = $6770

r = 7.6% = 0.076

t = 13

Thus;

V = 6770 * e^(0.076 * 13)

V = $18183.25

Answer:

Below

Step-by-step explanation:

So you need to find a denominator that both will divide 'evenly' into...

  12 would work.....4 will divide into it 'evenly' = 3

 You do to need to do anything to the '5/12 ' ....

So change 3/4 to 12ths by multiplying by ' 1 ' in the for 3/3

     3/4  * 3/3 =  (3* 3 ) / ( 3*4 ) = 9 / 12     Done.

The equation of the line is y = -4x - 15.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The line y = m(1)x + c is perpendicular to y = x/4 - 2.

This means,

y = (1/4)x - 2 is in the form of y = m(2)x + c

So,

m(1) x m(2) = -1

m(1) = -1 / (1/4)

m(1) = -4

Now,

The line intersects (4, -1).

So,

y = -4x + c

-1 = -4(4) + c

-1 = -16 + c

c = - + 16

c = -15

Thus,

The equation of the line perpendicular to y = x/4 - 2 is y = -4x - 15.

The population after 5 years will be approximately 8.45 billion.

The exponential equation to model the world population (in billions) after t years is P(t) = 8(1.011)^t, where P(t) is the population in billions and t is the number of years after 2022.

To write this equation, we need to use the information provided in the question. The initial population in 2022 is 8 billion, so this is our starting value. The growth rate is 1.1% per year, which can be written as 1.011 in decimal form.

We can use the formula for exponential growth, P(t) = P0(1 + r)^t, where P0 is the initial population, r is the growth rate, and t is the number of years.

Substituting the values for P0 and r into the equation, we get:

P(t) = 8(1.011)^t

This equation can be used to find the population after t years.

For example, to find the population after 5 years, we can substitute t = 5 into the equation and get:

P(5) = 8(1.011)^5 ≈ 8.45 billion

Therefore, the population after 5 years will be approximately 8.45 billion.

the question is asking for 2(x-7)=3

let's solve this by distributing

2x-14=3

2x=17

x=17/2

Answer: 2 (x - 7) = 3

If c = -4 d = 10, we can re-write the expression:

Answer: B. 9

Step-by-step explanation:

Let's learn some BIDMAS rules!

BIDMAS is an order of operation.

Multiply first or the indices? We can solve it with order of operations.

Here we go ↓↓

B = Brackets

I = Indices (³ ²)

D = Division

M = Multiplication

A = Addition

S = Subtraction

NOTE = Multiply or divide first? We do it from left to right

NOTE = Addition or Subtraction? We also do it from left to write in an equation.

Step 1 :

We replace all the letters with the given value, this make it :

[tex]1/4 (-4^{3} + 10^{2} )[/tex]=?

Step 2 :

Now, according to the rules, we do the numbers in the brackets first, now, in the brackets, there are indices, so we do those.

Which makes it :

1/4(-64+100)= ?

Step 3 :

Now we add the integers inside the brackets, remember, whenever the equation is like this, it is telling us it is a multiplication, here, it will be 1/4 x (-64+100) . In algebra, we don't use the × sign as it can be misinterpreted as [tex]x[/tex] .

1/4 (-64+100 = 36)

1/4 (36)

     =

   1/4 x 36

So we have = 1/4 x 36 at last.

Step 4 =

1/4 x 36 = 9

78° + B = 180°

B = 102°

"Supplementary" means angle A and B added together are 180°.

We know A is 78, but we don't know B

Write an equation:

A + B = 180°

Fill in what we know.

78° + B = 180° this is the equation the question is asking for.

To solve, subtract 78 from both sides of the equation.

If a shopkeeper gives you a 15% discount on shirt of having total price 50, the price you will give after the 15% discount is 42.5 dollars.

If the original price of the shirt is 50 dollars, and the shopkeeper gives a discount of 15%, then the discount amount is calculated by:

Discount = Original price x Discount rate

Discount = 50 x 0.15

Discount = 7.5 dollars

The discounted price is calculated by subtracting the discount from the original price:

Discounted price = Original price - Discount

Discounted price = 50 - 7.5

Discounted price = 42.5 dollars

The discount rate of 15% means that you will save 15% of the original price, which is 7.5 dollars in this case. The discounted price is the price after subtracting the discount amount from the original price.

Gwen's total sales and costs would be; 50 dollars.

An equation is an expression that shows the relationship between two or more numbers and variables.

Consider that x represent the number of pounds of soap that she makes and eventually sells.

we are given that Gwen intially spent $96 to purchase soap-making equipment, and the materials for each pound of soap cost $9. This means that the total cost of making x pounds of soap would be;

9x + 96

thus her revenue for x pounds of soap would be

25 × x = 25x

If she eventually sells enough soap to cover the cost of the equipment, then we get;

9x + 96 = 25x

25x - 9x = 96

x = 96/16

x = 6

she would need to sell make and sell 6 soaps.

The cost would be 9x + 96 = 150

The measure of ∠AOC of the circle is ∠AOC = 140°

The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.

The central angle of a circle formula is as follows.

Central Angle = ( s x 360° ) / 2πr

where s is the length of the arc

r is the radius of the circle

Central Angle = 2 x Angle in other segment

Given data ,

Let the measure of ∠ABC of the circle = 70°

Now , the sides AO and BO are the radius of the circle

where x + y = 70°

So , the measure of ∠AOB = 180 - 2x

And , the measure of ∠COB = 180 - 2y

Now , the measure of ∠AOC = 2 ( x + y )

On simplifying , we get

Central Angle = 2 x Angle in other segment

The measure of angle ∠AOC of the circle is = 2 ( 70 )°

The measure of angle ∠AOC of the circle is = 140°

m² +........+ 1/m²

We can notice that the expression has an even number of terms, and the first and last term are perfect squares, which suggests that it might be possible to write the expression as the square of a binomial.

Let's try to write the expression in the form of (a + b)²:

(a + b)² = a² + 2ab + b²

If we set a = m and b = 1/m, we get:

(a + b)² = m² + 2(m)(1/m) + (1/m)² = m² + 2 + 1/m²

Comparing this with the given expression, we see that it is the same as the given expression with 2 added to it.

Therefore, to make the given expression a perfect square, we need to add 2 to it.

So, the term to be inserted is 2.
