The interest rates required to get a total amount of $2,420 from compound interest on a principal of $2,000 compounded 1 times per year over 2 years is 10% per year.

The interest on savings that is calculated on both the initial principal and the interest accrued over time is known as compound interest.

The concept of compound interest, also known as "interest on interest," is thought to have first appeared in Italy in the 17th century. It will accelerate the growth of a sum more quickly than simple interest, which is calculated only on the principal sum.

Money is multiplied more quickly through compounding, and the more times it is compounded, the higher the compound interest will be.

Using the formula A = P(1 + r/n)^nt

Solving for rate r as a decimal

r = n[(A/P)^(1/nt) - 1]

r = 1 × [(2,420/2,000)^{1/(1)(2)} - 1]

r = 0.1

Then convert r to R as a percentage

R = r × 100

R = 0.1 × 100

R = 10%/year

Answer:

The solutions to the inequality are B, E, and F: 25, 36, and 9.

Step-by-step explanation:

The solutions to the inequality √x < 10 are the values of x that make the inequality true when plugged in. To find these values, we can square both sides of the inequality:

√x < 10

x < 10^2 = 100

So, the values of x that make the inequality true are those that are less than 100. The options that satisfy this condition are:

A. 100 (not a solution)

B. 25 (solution)

C. -100 (not a solution)

D. 105 (not a solution)

The slope of the new road is zero.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Take points from the Graph (5, 0) and (5, 4).

Slope of a line = m = tanθ

where θ is the angle made by the line with the x−axis.

For a line parallel to y−axis ,θ= π/2.

​

∴m = tan π/2 = undefined

The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.

An horizontal line now has zero slope.

The new road has a zero slope as a result.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

Answer:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

Step-by-step explanation:

Angle 1: Same-side interior angle of Line 1

Angle 2: Same-side interior angle of Line 2

We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:

Angle 1 + Angle 2 = 180

Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:

Angle 1 - Angle 2 = 50

We can rewrite this equation as:

Angle 1 = 50 + Angle 2

Now substitute this expression for Angle 1 into the first equation:

(50 + Angle 2) + Angle 2 = 180

Combine like terms:

2Angle 2 + 50 = 180

Subtract 50 from both sides:

2Angle 2 = 130

Divide by 2:

Angle 2 = 65

Now substitute this value back into the equation for Angle 1:

Angle 1 = 50 + Angle 2

Angle 1 = 50 + 65

Angle 1 = 115

Therefore, the angles are as follows:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

As a result, the percentage decrease in her new monthly payment is 18.1%. (to the nearest tenth).

To begin, we must determine the original loan amount. Using the information provided, we can construct the following equation:

$55,000 = P(1 + 0.10)^4

P denotes the original loan amount.

When we solve for P, we get:

P = $38,574.09

The old monthly payment is calculated as follows:

$38,574.09 / 1000 x $9.66 = $372.64

We must now compute the new loan amount. Because Sally renewed her mortgage at a 12% interest rate, we can apply the same formula as before, but with a new time period of 16 years (since 4 years have already passed):

Now, we need to calculate the new loan amount. Since Sally renewed the mortgage at a 12% interest rate, we can use the same formula as before, but with a new time period of 16 years (since 4 years have already passed):

$55,000 = P(1 + 0.12)^16

Solving for P, we get:

P = $27,703.25

The new monthly payment can be calculated as:

$27,703.25 / 1000 x $11.02 = $305.23

To find the percent increase, we can use the following formula:

percent increase = ((new value - old value) / old value) x 100

Plugging in the values, we get:

percent increase = (($305.23 - $372.64) / $372.64) x 100 = -18.1%

So the percent of decrease in her new monthly payment is 18.1% (to the nearest tenth).

The final price at pick-up will be approximately $28.64.

To calculate the final price of the order, we need to consider the wholesale cost, mark-up rate, and dispensing fee.

Calculate the cost per tablet

Since the wholesale cost is $829.00 for 1000 tablets, the cost per tablet can be found by dividing the total cost by the number of tablets:

Cost per tablet = Wholesale cost / Number of tablets

Cost per tablet = $829.00 / 1000 = $0.829

Calculate the mark-up amount

The mark-up rate is 14%, so we need to find 14% of the cost per tablet:

Mark-up amount = Mark-up rate * Cost per tablet

Mark-up amount = 0.14 * $0.829 = $0.11566

Calculate the total cost of the tablets

To find the total cost, we multiply the cost per tablet by the number of tablets in the order:

Total cost = Cost per tablet * Number of tablets

Total cost = $0.829 * 30 = $24.87

Calculate the final price

The final price includes the total cost, mark-up amount, and dispensing fee. Add these three amounts together to find the final price:

Final price = Total cost + Mark-up amount + Dispensing fee

Final price = $24.87 + $0.11566 + $3.65 = $28.63566

Since the final price is typically rounded to the nearest cent, the final price at pick-up will be approximately $28.64.

We have to write the point-slope equation of the line.

The point is (4,-2) and the slope has to be calculated.

We need another point to calculate the slope. We see that the y-intercept is y = 6, so another point of the line is (0, 6).

We then can calculate the slope with the points (0,6) and (4,-2):

Now that we have the slope m = -2 and the point (4,-2), we can write the equation as:

Answer: y + 2 = -2(x - 4)

Given that f, g, and h are bijective functions, and we have the composite function (gohof), the inverse of this function, (gohof)^-1, can be expressed as option c: h^-1 o g^-1 o f^-1.

First, let's break down the composition of functions gohof. When we apply the function f first, followed by g, then h, we get the composite function gohof.

Now, to find the inverse of gohof, we need to consider the inverse of each individual function in the reverse order. Let's denote the inverses of f, g, and h as f^-1, g^-1, and h^-1, respectively.

Using this notation, the correct form for the inverse of gohof is:

(gohof)^-1 = h^-1 o g^-1 o f^-1

Therefore, option (c) "the above h^-1 o g^-1 o f^-1" is the correct answer.

To understand why this is the correct form, let's consider the composition of functions. When we apply h^-1 first, followed by g^-1, then f^-1, we are effectively undoing the operations performed by f, g, and h in the reverse order.

By applying f^-1, we "reverse" the effect of f, effectively canceling it out. Then, by applying g^-1, we undo the effect of g, and finally, by applying h^-1, we reverse the effect of h.

The result is the inverse of the composite function gohof, which is obtained by reversing the order of the functions and applying their respective inverses.

It's important to note that this conclusion holds true because we are assuming that f, g, and h are bijective functions, meaning they are both injective (one-to-one) and surjective (onto). In such cases, the inverses of the individual functions exist, and the composition of their inverses in the reverse order gives us the inverse of the composite function.

Heuristics refers to rules of thumb that simplify the decision-making process. Heuristics are mental shortcuts that help individuals make decisions quickly, often relying on previous experience or intuition rather than a more systematic approach.

While heuristics can be useful, they can also lead to biases and errors in judgment if they are applied too broadly or without careful consideration. It is important to be aware of these heuristics and how they can affect decision-making processes, especially in complex or high-stakes situations where careful consideration is necessary.

You sent 19 text messages. Let's start by using variables to represent the unknown quantities in the problem. Let t be the number of text messages sent, and let p be the number of pictures sent.

We know that it costs $0.07 to send a text message and $0.12 to send a picture, and we also know that the total amount spent was $3.38. So we can write two equations based on this information:

0.07t + 0.12p = 3.38 (equation 1)

t = 2p (equation 2)

We can use equation 2 to substitute for t in equation 1:

0.07(2p) + 0.12p = 3.38

Simplifying this equation gives:

0.26p = 3.38

p = 13

So you sent 13 pictures. Now we can use equation 2 to find the number of text messages sent:

t = 2p = 2(13) = 26

So you sent 26 text messages. However, we should check if this answer is consistent with the total amount spent:

0.07(26) + 0.12(13) = 1.82 + 1.56 = 3.38

This checks out, so the final answer is that you sent 26 text messages and 13 pictures.

There are no free variables or parameters, and the number of parameters in the general solution of Ax=0 is at most 0.

(a) If A is a 2×6 matrix, then the number of leading 1's in the reduced row echelon form of A is at most 2.

In the reduced row echelon form (RREF), the leading 1's are the first non-zero entry in each row. Since A is a 2×6 matrix, it can have at most two rows. In the RREF, each row can have at most one leading 1. Therefore, the maximum number of leading 1's in the RREF of A is 2.

(b) If A is a 2×6 matrix, then the number of parameters in the general solution of Ax=0 is at most 4.

The general solution of Ax=0 represents the solutions to the homogeneous equation when A is multiplied by a vector x resulting in the zero vector. The number of parameters in the general solution corresponds to the number of free variables or unknowns that can take any value.

In this case, since A is a 2×6 matrix, we have 6 variables but only 2 equations. This means that there will be 6 - 2 = 4 free variables or parameters. Therefore, the number of parameters in the general solution of Ax=0 is at most 4.

(c) If A is a 6×2 matrix, then the number of leading 1's in the reduced row echelon form of A is at most 2.

In the reduced row echelon form (RREF), the leading 1's are the first non-zero entry in each row. Since A is a 6×2 matrix, it can have at most two columns. In the RREF, each column can have at most one leading 1. Therefore, the maximum number of leading 1's in the RREF of A is 2.

(d) If A is a 6×2 matrix, then the number of parameters in the general solution of Ax=0 is at most 0.

Since A is a 6×2 matrix, we have more rows (6) than columns (2). This implies that the system of equations represented by Ax=0 is overdetermined. In an overdetermined system, it is possible for there to be no non-trivial solutions, meaning the only solution is x = 0.

For given functions f(x) and g(x), the value of  (f °g)(12) is 24.

What exactly is a function?

In mathematics, a function is a rule that assigns to each input value (also called the argument) exactly one output value. The input values are typically drawn from a specific set, called the domain of the function, and the output values are drawn from another set, called the range of the function.

Now,

To find (f °g)(12), we need to first evaluate g(12) and then use the result to evaluate f(g(12)).

g(x) = √(x+4), so g(12) = √(12+4) = √16 = 4.

f(x) = 4x+8, so f(g(12)) = f(4) = 4(4) + 8 = 16 + 8 = 24.

Therefore,

                  The value of (f ° g)(12) = f(g(12)) = 24.
