Answer:

1) 8,388,608 grains of wheat.

2) 16,777,215 grains of wheat.

3) 239,674.5 pounds.

Step-by-step explanation:

Question 1)

We know that on the first square, there is 1 grain of wheat.

On the second, 2 grains of wheat.

On the third, 4 grains of wheat.

And on the fourth, 8 grains of wheat.

Therefore, we have a geometrically increasing sequence. It looks like:

1, 2, 4, 8...

Therefore, to find the number of grains on the 24th square, we can write an explicit formula.

The standard form for the explicit formula for a geometric sequence is:

[tex]x_n=a(r)^{n-1}[/tex]

Where a is the initial amount, r is the common ratio, and n is the nth term (starting from 1).

We know that the initial term a is 1 because there’s one grain of wheat on the first square.

And the common ratio will be 2 because each square has double the amount of the previous square.

So, substitute 1 for a and 2 for r. This yields:

[tex]x_n=1(2)^{n-1}\\[/tex]

We can simplify this:

[tex]x_n=2^{n-1}[/tex]

So, to find the amount of wheat on the 24th square, we simply need to substitute 24 for n and evaluate. So:

[tex]x_{24}=2^{24-1}=2^{23}[/tex]

Evaluate. Use a calculator:

[tex]x_{24}=8,388,608[/tex]

Therefore, on the 24th square, there are 8,388,608 grains of wheat.

Question 2.1)

We want to find the total number of grains of wheat on the board at this time.

In other words, we want to find the sum of our geometric sequence when n is 24.

The formula for the sum of a geometric series is:

[tex]S_n=\frac{a(r^n-1)}{r-1}[/tex]

Where rⁿ is the value of the number of terms n, r is the common ratio, and a is the initial term.

We want to find the sum after 24 times. So, n is 24.

So, substitute 24 for n, 2 for r, and 1 for a. This yields:

[tex]S_{24}=\frac{(1)(2^{24}-1)}{2-1}[/tex]

Evaluate. Use a calculator:

[tex]S_{24}=16, 777, 215[/tex]

Therefore, the total sum of the number of grains of wheat at the board at the 24th square is 16,777,215.

Question 2.2)

And to find the weight, we will just have to multiply our total amount by 1/7000. So:

[tex]W=16777215(\frac{1}{70})[/tex]

Use a calculator:

[tex]W=239,674.5\text{ lbs}[/tex]

So, the total weight is 239,674.5 pounds.

Answer:

1x = 3x

Step-by-step explanation:

This is could be wrong not sure.

Answer:

-(-4)(-6)*3/5(10+15)

when there is a (-) in front of an expression in parentheses, change the sing of each term in the expression.

4*(-6)*3/5*(10+15)

Add the numbers (10+15)

4(-6)*3/5*25

multiplying an odd number of negative terms makes the product negative

-4*6*3/5*25

reduce the number with the greatest common factor 5

-4*6*3*5

calculate the product

solution

-360

Answer:

-9

Step-by-step explanation:

the number is x

2x = 4x - - 18

2x = 4x + 18

-2x = 18

x = -9

Answer:

-9

Step-by-step explanation:

Let's solve your equation step-by-step.

2x=4x−(−18)

Step 1: Simplify both sides of the equation.

2x=4x+18

Step 2: Subtract 4x from both sides.

2x−4x=4x+18−4x

−2x=18

Step 3: Divide both sides by -2.

−2x/−2

= 18 /−2 x

=−9

Answer:

150

Step-by-step explanation:

This is a word problem which should be tackled accordingly.

The sum of 48 and itself

= 48+48

= 96

It's half and half of its half

= 48/2 and (48/2)/2

= 24+ 24/2

= 24+12

= 36

Is added to 18

= 96+36+18

= 150

From the description above the entire sum is 150.

Answer:

-9xy² - 6x²y + 5x

Step-by-step explanation:

The additive inverse of a polynomial is simply defined as the same polynomial but the difference is that the signs attached to each of the terms will change. This means that positive sign will change to negative while negative sign will change to positive.

Now, we are given the polynomial;

9xy² + 6x²y - 5x

Thus, from earlier description, additive inverse of this polynomial is;

-9xy² - 6x²y + 5x

Answer:

a. s = [tex]\frac{d}{t}[/tex]

b. 9600 ft

Step-by-step explanation:

In the given question, the motion of the bee involves speed (s), distance (d) and its time of flight (t).

a. The equation required to determine the distance of the flowerbed from the hive/ hive to flowerbed is;

speed = [tex]\frac{distance}{time}[/tex]

i.e s = [tex]\frac{d}{t}[/tex]

b. Given that: the bee flies back at 8 feet per second, and in 20 minutes (1200 seconds);

s = [tex]\frac{d}{t}[/tex]

⇒ d = s x t

       = 8 ft/s x 1200 s

       = 9600 ft

The flowerbed is 9600 feet from the hive.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Principal = $20000

Interest rate = 5.5% = 0.055 compounded daily

Time = 16years =(360 * 16) = 5760

n = number of times interest is applied per period

Amount of money in account after 16 years :

A = p(1 + r/n)^nt

A = total amount

A = 20000(1 + 0.055/360)^(360*16)

A = 20000(1 + 0.0001527)^5760

A = 20000(1.0001527)^5760

A = 48193.1611

Interest on principal :

$48193.1611 - $20000

= $28193.1611

Answer:

The answer is B.

Step-by-step explanation:

Answer:

18 at most.

Step-by-step explanation:

Step-by-step explanation:

Let the initial population of a community be P0 and the population after time t is P(t).

If the population of a community is known to increase at a rate proportional to the number of people present at time t, this is expressed as:

[tex]P(t) = P_0e^{kt}[/tex]

at t = 5 years, P(t) = 2P0

substitute:

[tex]2P_0 = P_0e^{5k}\\2 = e^{5k}\\ln2 = lne^{5k}\\ln2 = 5k\\k = \frac{ln2}{5}\\k = 0.1386[/tex]

If the population is 9,000 after 3 years

at t = 3, P(t) = 9000

a) Substitute into the formula to get P0

[tex]9000 = P_0e^{0.1386\times 3}\\9000 = P_0e^{0.4158}\\9000 = 1.5156P_0\\P_0 = \frac{9000}{1.5156}\\ P_0 = 5938.24[/tex]

Hence the initial population is approximately 5938.

b) In order to know how fast the population growing at t = 10, we will substitute t = 10 into the formula as shown:

[tex]P(10) = 5938.24e^{0.1386(10)}\\P(10) = 5938.24e^{1.386}\\P(10) = 5938.24(3.9988)\\P(10) = 23,745.97[/tex]

Hence the population of the community after 10 years is approximately 23,746

Answer:

The least common denominator is 77 so the fractions would become 63/77 and 66/77.

Answer:

A) True

Step-by-step explanation:

[tex]-4,-1[/tex]

If we subtract the two numbers we get

[tex]-4-(-1)=-4+1=-3[/tex]

It can be seen that subtracting the two numbers changes the sign of one number by which we can algebraically subtract the numbers. Since, the addition of 1 shifts the number towards zero in the number line, the minus sign still remains.

So A)-4 -1 is true.

Step-by-step explanation:

Answer:

When V is composed with r, the composite function is [tex]\frac{1}{48} \pi t^{6}[/tex]

When Vr6 shows that the volume is 9724. When the radius is increased to 6 inches.

Step-by-step explanation:

Volume is determined by [tex]cm^{3}[/tex] if the balloon is filled with air its volume will be increased and the composite function will represent the volume of the balloon. The radius of the balloon will rise in seconds. If t seconds are consumed to reach to a radius of 6 inches then the pie function is used to determine the volume.
