We can order the bonds from slowest-growing to fastest-growing as:

First bond: fixed growth rate of $50 per year

Third bond: growth rate of 4% per year, compounded continuously

Second bond: growth rate of 6% per year, compounded annually

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To order the bonds from slowest growing to fastest growing, we need to compare their growth rates.

The first bond grows at a fixed rate of $50 per year, regardless of how long it is held.

So its growth rate is constant and does not change with time.

The second bond is worth $500 and grows at a fixed annual rate of 6%, so its value after one year will be:

Value after one year
= $500 + 0.06 x $500

= $530

After two years, its value will be:

Value after two years.

= $530 + 0.06 x $530

= $561.80

We can see that the second bond's growth rate is increasing over time since the increase in value each year is calculated as a percentage of the new value.

The third bond is worth $100 and grows at an annual rate of 4% that is applied continuously.

The formula for the value of a continuously compounded bond after t years  = $100 x e^(0.04t)

where e is the mathematical constant approximately equal to 2.718.

After one year,

The value of the third bond.

= $100 x e^(0.04 x 1) = $104.08

After two years,

Value after two years

= $100 x e^(0.04 x 2)

= $108.24

We can see that the growth rate of the third bond is also increasing over time because the interest is being compounded continuously.

Now,

We can order the bonds from slowest-growing to fastest-growing as:

First bond: fixed growth rate of $50 per year

Third bond: growth rate of 4% per year, compounded continuously

Second bond: growth rate of 6% per year, compounded annually

Step-by-step explanation:

The expression for the composition of functions t and s, (t*s)(x), is obtained by substituting the output of s(x) into t(x). So,

(t*s)(x) = t(s(x)) = t(4x) = 3(4x) + 3 = 12x + 3.

The expression for the difference of functions t and s, (t - s)(x), is obtained by subtracting the output of s(x) from t(x). So,

(t - s)(x) = t(x) - s(x) = (3x + 3) - (4x) = -x + 3.

To evaluate (t + s)(-2), we need to add the outputs of t(-2) and s(-2).

t(-2) = 3(-2) + 3 = 3

s(-2) = 4(-2) = -8

So, (t + s)(-2) = t(-2) + s(-2) = 3 + (-8) = -5.

The equation -13x+12-(-13x+12)-13x+12 = -13x+12   is equivalent to the given expression that is -13x+12.

10x^2 - 23x + 12 = (5x - 3)(2x - 4) = 0

So the solutions to the equation are x = 3/5 or x = 2.

Therefore, this expression is not equivalent to -23x + 12 for all values of x.

10x^2 - 7x - 12 = 0 can be factored as (2x - 3)(5x + 4) = 0.

So the solutions to the equation are x = 3/2 or x = -4/5.

Therefore, this expression is not equivalent to -7x - 12 for all values of x.

-13x+12-(-13x+12)-13x+12  = -13x+12

-13x+12  = -13x+12

This expression is equivalent to -13x+12 .

7x^2 - 23x - 77 = (7x + 11)(x - 7) = 0

So the solutions to the equation are x = -11/7 or x = 7.

Therefore, this expression is not equivalent to -23x - 7 for all value x.

The given expressions of each case are not equivalent to the given equations for all values of x, except −13x+12-(-13x+12)-13x+12  = -13x+12 which is equivalent to -13x+12 .

The boat travels a distance of [tex](1/2k) ln(61/42)^2[/tex] in the first 2 minutes after its motor quits.

We can solve this problem using separation of variables. The differential equation that models the velocity of the boat is:

[tex]dv/dt = -kv^2[/tex]

To do this, we first need to separate the variables and integrate both sides:

[tex]1/v^2 dv = -k dt[/tex]

Integrating both sides, we get:

-1/v = kt + C

where C is the constant of integration. To find C, we can use the initial condition that the boat is moving at 83 ft/s when the motor quits:

-1/83 = k(1) + C

C = -1/83 + k

Now we can substitute C back into our equation:

-1/v = kt - 1/83 + k

Solving for v, we get:

v = 1 / (k(t - 1/83 + 1))

Now we can integrate v over the time interval [1, 121] to find the distance traveled by the boat:

d = ∫[1,121] v dt

Substituting v into the integral, we get:

d = ∫[1,121] 1 / (k(t - 1/83 + 1)) dt

We can simplify the integral by using the substitution u = t - 1/83 + 1:

d = ∫[84/83, 122/83] 1 / (ku) du

Now we can integrate this expression to get:

d = ln(u) / k |[84/83, 122/83]

d = ln(122/83) / k - ln(84/83) / k

d = (1/k) ln(122/83) - (1/k) ln(84/83)

We can simplify this expression using the fact that C = -1/83 + k:

d = (1/k) ln(122/83 / 84/83)

d = (1/k) ln(61/42)

Finally, we can plug in the initial condition k > 0 to get the distance traveled by the boat:

d = [tex](1/k) ln(61/42) = (1/2k) ln(61/42)^2[/tex]

d = [tex](1/2k) ln(61/42)^2[/tex]

Since we are not given the value of k, we cannot compute the exact numerical value of the distance traveled.

The height of the tree is approximately 156.7 feet.

What is Trigonometry?

Trigonometry is the study of angles and the angular relationships of planar and three-dimensional shapes. Trigonometry is made up of trigonometric functions (also known as circle functions) such as cosecant, cosine, cotangent, secant, sine, and tangent.

The height of the tree can be calculated using trigonometry.

Let's call the height of the tree "h".

Then, using the right triangle formed by the height of the tree, the distance from the base of the tree to where Jerome is standing, and the angle between the ground and the top of the tree, we can set up the following equation:

tan(33°) = h / 90

Solving for h, we get:

h = 90 * tan(33°)

Using a calculator to find the value of tan(33°), we get:

h = 90 * 1.730

Yes, both methods give the same result. The chain rule is used to differentiate a composite function, while the substitution method is used to differentiate a function after substituting a variable with its expression.

The chain rule is used to differentiate a composite function, which is a function of a function. To use the chain rule, we differentiate the inner function and multiply it by the derivative of the outer function. In this case, we would have

f(x) = ([tex]x^2 + 3x + 2[/tex]) and

g(x) = [tex]2x^3 + 5[/tex]

The derivative of f(x) would be 2x + 3 and the derivative of g(x) would be [tex]6x^2[/tex]. Taking the product of these two derivatives, we get

[tex]12x^3 + 18x^2[/tex],

which is the answer we get using the chain rule. The substitution method involves substituting a variable in a function with its expression. In this case, we substitute x with ([tex]x^2 + 3x + 2[/tex]). This gives us a new function that is a function of [tex]x^2 + 3x + 2[/tex]instead of x. We then differentiate this new function and the answer we get is the same as the one we got using the chain rule. Therefore, both methods give the same result and agree with each other.

A polygon with a sum of interior angles of 3960 has 22 sides.

The sum of the interior angles of a polygon can be calculated using the formula:

(n-2) * 180

where n is the number of sides of the polygon. This formula is derived from the fact that the total degree measure of a polygon is equal to the sum of the degree measures of its interior angles. In a polygon with n sides, there are n angles, each measuring 180 degrees. So the total degree measure of a polygon with n sides is n * 180.

Now, if we subtract the degree measures of two angles, we are left with the sum of the degree measures of the remaining n-2 angles. This is why the formula for the sum of the interior angles of a polygon is given as (n-2) * 180.

To find the number of sides of a polygon given its sum of interior angles, we can rearrange the formula as follows:

n = (Sum of interior angles / 180) + 2

So, if the sum of the interior angles is given as 3960, we can plug that into the formula:

n = (3960 / 180) + 2

n = 22

Therefore, a polygon with a sum of interior angles of 3960 has 22 sides.
