Answer: 1260

Step-by-step explanation:

To solve for simple interest, we can use the formula:

I = P * r * t

where:

I = interest

P = principal amount

r = interest rate

t = time (in years)

In this case:

P = 2400

r = 10.5% = 0.105 (note that we convert the percentage to a decimal)

t = 5

Substituting these values into the formula, we get:

I = 2400 * 0.105 * 5

I = 1260

Therefore, the simple interest on a principal amount of 2400 at 10.5% for 5 years is 1260.

The wave is polarized parallel to the y-axis, and the magnetic field lines are parallel to the x-axis. Here option D is the correct answer.

The oscillating electric dipole along the z-axis creates an electromagnetic wave with electric and magnetic fields perpendicular to each other and to the direction of wave propagation. At a position on the y-axis far from the origin, the electric field will be parallel to the y-axis.

The polarization of the wave refers to the orientation of the electric field vector. Since the electric field is parallel to the y-axis, the wave is polarized parallel to the y-axis.

According to the right-hand rule, the direction of the magnetic field lines will be perpendicular to both the electric field and the direction of wave propagation, which is along the z-axis. Therefore, the magnetic field lines will be parallel to the x-axis.

We have triangle ABC, the length of side AB is 16 inches and the length of side BC is 24 inches, the possible length of the side AC is less than 40 inches

To find the possible length of side AC, we need to use the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side, that is, a + b > c, b + c > a, c + a > b.

Now, for the given triangle ABC:

a = AB = 16 inches

b = BC = 24 inches

c = AC

We know that a + b > c (using the triangle inequality theorem)

16 + 24 > cc < 40

Flipping a coin 3 times, the probability of getting 3 heads is 0.125.

The probability of getting 3 heads when a coin is flipped 3 times can be calculated using the binomial probability formula. The formula is:

P(X=k) = nCk × p^k × (1-p)^(n-k)

where n is the number of trials, k is the number of successes, p is the probability of success, and (1-p) is the probability of failure.

Here, n=3, k=3 and p=0.5 (since the coin has two sides and the probability of getting heads or tails is 0.5 each). Substituting the values, we get:

P(X=3) = 3C3 × 0.5³ × (1-0.5)⁽³⁻³⁾ = 1 × 0.125 × 1 = 0.125

Therefore, the probability of getting 3 heads as a decimal rounded to 3 decimal places is 0.125.

The score that could not be your exam score is 70.The correct option is (a).To calculate the standard deviation of a set of data, you take the square root of the average of the squared differences of the values from the mean.

The question is asking which of the given scores could not be your exam score if your exam score is 2.12 standard deviations below the mean. The mean score on the exam is 82, so the score that is 2.12 standard deviations below the mean is: 82 - (2.12 x standard deviation) = 82 - (2.12 x 10) = 70.Therefore, the score that could not be your exam score is 70.

To explain further, standard deviation is a measure of how spread out the numbers in a set of data .The other options (85, 80, and 90) are not correct because they are not 2.12 standard deviations below the mean. To summarize, the score that is 2.12 standard deviations below the mean score of 82 is 70.

Using equations we know that 45 pounds are included in the $1.40 worth of groceries and 55 pounds worth of groceries are being purchased for 40 cents.

An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.

As in 3x + 5 = 15, for example.

There are many different types of equations, including linear, quadratic, cubic, and others.

So, we have:

x + y = 100                        .........A

40 × x + 140 y = 85 × 100

40 x + 140 y = 8500         ........B

Solving (A) and (B) as follows:

(40 x + 140 y) - 40 × ( x + y ) = 8500 - 40 × 100

(40 x - 40 x) + (140 y - 40 y) = 8500 - 4000

0 + 100 y = 4500

y = 4500/100

Hence, the price per unit of grocery is $1.40 = y = 45 pounds.

Now, put the value of y in equation (A) as follows:

x + y = 100

x = 100 - y

x = 100 - 45

x = 55 pounds

The number of groceries at the 40-cent price is x = 55 pounds.

Therefore, using equations we know that 45 pounds are included in the $1.40 worth of groceries and 55 pounds worth of groceries are being purchased for 40 cents.

Answer:

A (-439)

Step-by-step explanation:

To find the value of (s•t)(-7), we need to first evaluate s(t(-7)) which means we substitute -7 for x in the function t, and then substitute the resulting value in the function s.

So, we have:

t(-7) = 3(-7) = -21

s(-21) = 2 - (-21)^2 = 2 - 441 = -439

Therefore, the value of (s•t)(-7) is -439, which corresponds to option A.

So, the correct answer is A(-439).

Answer:

A

Step-by-step explanation:

I believe you mean

(s ￮ t)(- 7)

to evaluate, first evaluate t(- 7) then substitute the value obtained into s(x)

t(- 7) = 3(- 7) = - 21 , then

s(- 21) = 2 - (- 21)² = 2 - 441 = - 439

The car will never have a value of £0 because the formula for depreciation approaches but never reaches zero.

Percent is a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin per centum, which means "per hundred". Percentages are often used to represent rates, ratios, or proportions of a quantity. For example, if a student scores 90 out of 100 on a test, their score can be expressed as 90%, or 0.9 as a decimal. Similarly, if a store offers a discount of 20% on a product, it means that the customer can purchase the product for 80% of its original price, or 0.8 as a decimal. Percentages are commonly used in finance, science, and everyday life to represent various types of information, such as interest rates, probabilities, taxes, and discounts.

Here,

1. Amount after 1 year:

The amount after 1 year can be calculated using the formula for compound interest:

A = P(1 + r/n)ⁿˣ

Where A is the amount, P is the principal amount, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time in years.

Substituting the given values, we get:

A = 1000(1 + 0.05/1)¹*¹= £1050

Therefore, the total amount in the bank account after 1 year is £1050.

2. Amount after 2 years:

Using the same formula, we get:

A = 1000(1 + 0.05/1)¹*² = £1102.50

Therefore, the total amount in the bank account after 2 years is £1102.50.

3. Amount after 3 years:

Using the same formula, we get:

A = 1000(1 + 0.05/1)¹*³ = £1157.63

Therefore, the total amount in the bank account after 3 years is £1157.63.

4. Amount after 6 years:

Using the same formula, we get:

A = 1000(1 + 0.05/1)¹*⁶ = £1345.99

Therefore, the total amount in the bank account after 6 years is £1345.99.

5. The amount of interest earned after 6 years is not equal to double the amount of interest earned after 3 years because the interest earned in each year is added to the principal amount, so the interest earned in subsequent years is based on a larger principal amount. This leads to exponential growth in the amount of interest earned over time.

6. The value of the car after n years can be calculated using the formula:

V = P(1 - r/100)ⁿ

where V is the value of the car after n years, P is the initial value of the car, r is the rate of depreciation per year, and n is the number of years.

Using this formula, we can calculate the value of the car after:

1 year: V = 1000(1 - 0.05)¹ = £950

2 years: V = 1000(1 - 0.05)² = £902.50

3 years: V = 1000(1 - 0.05)³ = £857.38

6 years: V = 1000(1 - 0.05)⁶ = £735.03

Answer: b

Step-by-step explanation: just took it on edge.

W in terms of t can be represented as W = 7.5t + 10.

When a baby weighs 10 pounds at birth and 40 pounds four years later, we must apply the linear equation to represent W in terms of t.

y = mx + b,

where

m indictaes the slope of the line while

b is the y-intercept.

The formula to find the slope of a line is as follows:

Slope (m) = (y2 - y1) over (x2 - x1)

Given that a baby weighs 10 pounds at birth, and four years later, the child's weight is 40 pounds, we can determine the slope of the line as:

Slope (m) = (40 - 10) over (4 - 0) = 30 / 4 = 7.5

Thus, the linear equation relating childhood weight W (in pounds) to age t (in years) is:

W = 7.5t + 10

Therefore, we can express W in terms of t as W = 7.5t + 10.
