By using compound interest formula, we conclude that Sophie deposited $16,638 (rounded to the nearest whole number) into the account.

Compound interest is a method of calculating interest on a principal amount of money, where the interest earned on the initial principal is added to the principal at the end of each compounding period (usually monthly, quarterly, or annually).

We can use the formula for compound interest to solve this problem. The formula is:

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

Where:

A = the total amount in the account

P = the principal (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

We know the values for A, r, n, and t, so we can solve for P:

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

[tex]22,099.87 = P(1 + 0.022/2)^{(2*13)[/tex]

[tex]22,099.87 = P(1.011)^{26[/tex]

22,099.87 = 1.329P

P = 22,099.87 / 1.329

P = 16,637.55

Therefore, Sophie deposited $16,638 (rounded to the nearest whole number) into the account.

Answer:

[tex]f(x)=4(3)^x[/tex]

Step-by-step explanation:

The general equation for an exponential function is:

[tex]\boxed{f(x) = ab^x}[/tex]

where:

To find the values of a and b that satisfy the given conditions, we can use the two points (1, 12) and (3, 108) to form a system of equations:

[tex]\begin{cases}12 = ab^1\\108 = ab^3\end{cases}[/tex]

Divide the second equation by the first equation to eliminate a:

[tex]\dfrac{ab^3}{ab} = \dfrac{108}{12}[/tex]

[tex]b^2=9[/tex]

[tex]\sqrt{b^2}=\sqrt{9}[/tex]

[tex]b=3[/tex]

Substitute the found value of b into the first equation and solve for a:

[tex]12&=3a[/tex]

[tex]\dfrac{12}{3}=\dfrac{3a}{3}[/tex]

[tex]4=a[/tex]

[tex]a=4[/tex]

Therefore, the equation of the exponential function that passes through the points (1, 12) and (3, 108) is:

[tex]\boxed{f(x) = 4(3)^x}[/tex]

Answer:

Step-by-step explanation:

To find the equation of an exponential function passing through the given points (1,12) and (3,108),

we can use the standard exponential form y=a(b^x). We know that when x=1, y=12,

so we can substitute these values into the equation to find a.

So  12 = a(b^1). Similarly, when x=3, y=108, so 108 = a(b^3). We can divide the second equation by the first to eliminate a and get (108/12) = b^2, or 9 = b^2. Thus, b=3 (taking only the positive root). We can now substitute this value of b into either equation to find a. Using the first equation, we get 12 = a(3^1), so a=4. Therefore, the exponential function passing through the given points is y=4(3^x).

Using the magnitude formula we know the amount of energy released by an earthquake with a magnitude of 5.5 is 4.5 * 10¹².

The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics.

Formally speaking, the size of an object is the visible outcome of an ordering—of the class of objects to which it belongs.

The most frequent way to gauge an earthquake's size is through its magnitude.

It is a gauge for the magnitude of an earthquake's sole source.

As a result, it is the same regardless of how or where you view it, and the following computation can be made:

So, in the given situation we will be using the formula:

M = 2/3 log E/E₀

Where E is the power released in Joules and x, the minimal measure released by such an earthquake shall be allotted to.

Assuming 5.5, the same magnitude is given when the above equation is used:

M = 2/3 log E/E₀

5.5 = 2/3 log (E/10⁴°⁴)

8.5 = log (E/10⁴°⁴)

10⁸°⁵ = E/10⁴°⁴

E = 10⁴°⁴ * 10⁸°⁵

E = 4.5 * 10¹²

Therefore, using the magnitude formula we know the amount of energy released by an earthquake with a magnitude of 5.5 is 4.5 * 10¹².

Answer:3-7=5

Step-by-step explanation: 3-7=5

Answer:

(a) The total ratio is 1 + 3 = 4, so Jill's share is (3/4) of £60:

Jill's share = (3/4) × £60 = £45.

(b) The ratio of their ages remains the same, so if Jack is one year older, Jill is also one year older. Therefore, Jill's age is 4 and Jack's age is 2, and Jack's share is (2/4) of £60:

Jack's share = (1/2) × £60 = £30.

(c) Let x be the age of Jack when he receives £25 from Uncle Fred. According to the problem, Jill is always two years older than Jack. Therefore, when Jack is x years old, Jill is x + 2 years old. The ratio of their ages is x : (x + 2), and this ratio is equal to 5/7 (25 pounds is 5/7 of 35 pounds, which is the total amount that they will receive). We can write an equation to solve for x:

x/(x+2) = 5/7

7x = 5(x + 2)

7x = 5x + 10

2x = 10

x = 5

Therefore, Jack will be 5 years old when he receives £25 from Uncle Fred at Christmas.

A) £45 because Jill will get 3/4 and Jack will get 1/4. To check our work, 60 divided by 4 is 15. 15 times 3 is 45 and 15 times one is 15.

B) £30 because it is a new year, both nephews will increase by one year. Now Jill is 4 and Jack is 2. So each kid will get half the share. 2 divided by 4 is 0.5 which is half of one. Half of 60 is 30.

C) 5 years Jill will always be 2 years older than Jack; this shows us that if some more years pass, Jill will be 7 and Jack will be 5 —> 1/4 x £60 = £25 Multiplying both sides by 4/60, we get:x = 5/4. This means Jack will be 5.

The common difference of the sequence is - 100.

The explicit formula of the sequence is  131 - 100n.

The 52 term of the sequence is -5069.

Let's find the explicit formula of the arithmetic sequence as follows:

31, -69, -169, -269

We will find the common difference and the 52 terms.

Therefore,

a + (n + 1)d = nth term

where

Therefore,

d = common difference = -69  - 31 = - 100

Therefore,

nth term = 31 + (n - 1)-100

nth term = 31 - 100n + 100

nth term = 131 - 100n

Let's find the 52 term

The volume of the cone is 288π m³. Hence, the answer is option C, 288π m³.

A cone is a shape created by connecting all the points of a circular base (which does not contain the apex) to a common point known as the apex or vertex using a series of line segments or lines. The height of the cone is determined by measuring the distance between its vertex and base.

The formula for the volume of a cone is given by V = (1/3)πr²h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3)π(6²)(24)

V = (1/3)π(36)(24)

V = (1/3)(864π)

V = 288π

Therefore, the volume of the cone is 288π m³.

The value of (a) in given triangle is approximately 7.44 cm.

A triangle is a three-sided polygon consisting of three sides and three vertices. The most important property of a triangle is that the sum of its interior angles  is  180 degrees.

Let ΔABC is a triangle

Given ∠ B = 75°

∠ C = 31.8°

AB = 12cm

AC = 22cm

find BC = ?

We can use the law of cosines to solve for BC:

BC² = AB² + AC² – 2(AB)(AC)cos(B)

We know that angle B = 75 degrees, so we can substitute:

BC² = 12² + 22² - 2(12)(22)cos(75)

Evaluating cos(75) with a calculator, we get:

BC² ≈ 144 + 484 - 572.59

BC² ≈ 55.41

Taking the square root of both sides gives us:

BC ≈ 7.44

To determine if the given equations are symmetric with respect to the origin, we need to check if replacing x with -x and y with -y results in the same equation.

For the equations given:

y=7x-4 is not symmetric with respect to the origin since replacing x with -x and y with -y gives y=-7x+4, which is not the same equation.

y= -x+7 is not symmetric with respect to the origin since replacing x with -x and y with -y gives y=x-7, which is not the same equation.

y = -7x^2 is symmetric with respect to the origin since replacing x with -x and y with -y gives -y = -7(-x)^2, which simplifies to -y = -7x^2. Thus, the equation remains the same.

y = 6x^2 - 9 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y = 6(-x)^2 - 9, which simplifies to -y = 6x^2 - 9. Thus, the equation is not the same.

x=1/4 y^2 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -x = 1/4 (-y)^2, which simplifies to -x = 1/4 y^2. Thus, the equation is not the same.

x = -y^2 + 9 is symmetric with respect to the origin since replacing x with -x and y with -y gives -x = -(-y)^2 + 9, which simplifies to -x = -y^2 + 9. Thus, the equation remains the same.

y=-1/6 x^3 is symmetric with respect to the origin since replacing x with -x and y with -y gives -y=-1/6(-x)^3, which simplifies to -y=-1/6 x^3. Thus, the equation remains the same.

y=x^3-1 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=(-x)^3-1, which simplifies to -y=-x^3-1. Thus, the equation is not the same.

y=sqrt(x) is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=sqrt(-x), which is not the same equation.

y=sqrt(x)-6 is not symmetric with respect to the origin since replacing x with -x and y with -y gives -y=sqrt(-x)-6, which is not the same equation.

Therefore, the only equation that is symmetric with respect to the origin is y = -7x^2.
