(5^2-3^2)-(5-3)-^2=?

Answer: 8.24%

Step-by-step explanation:

To calculate the annual percentage rate (APR) and the effective annual rate of interest on Aruna's investment, we need to know the following information:

The initial investment amount (Rs 150,000)

The final investment amount (Rs 168,925)

The time period of the investment (18 months)

The frequency of interest payments (every 3 months)

The interest earned on the investment is the difference between the final investment amount and the initial investment amount. In this case, the interest earned is:

Rs 168,925 - Rs 150,000 = Rs 18,925.

Calculate the interest rate per period: To find the interest rate per period, divide the interest earned by the initial investment amount and multiply by the number of periods per year. In this case, the interest rate per period is:

(Rs 18,925 / Rs 150,000) * (4 periods per year) = 0.08%.

Calculate the APR: The APR is the interest rate per period multiplied by the number of periods in the investment. In this case, the APR is:

0.08% * 18 months = 8%.

The effective annual rate of interest takes into account the compounding of interest over time. To calculate the effective annual rate of interest, we use the formula:

(1 + r/n)^n - 1, where r is the interest rate per period and n is the number of compounding periods per year.

In this case, the effective annual rate of interest is:

(1 + 0.08%/4)^4 - 1 = 8.24%.

So the annual percentage rate (APR) is 8% and the effective annual rate of interest is 8.24%

The probability that all six dice show a one is 1/46656

From the question, we have the following parameters that can be used in our computation:

Number of dices = 6

Outcome = all 1

The probability of rolling a one on one die is 1/6.

So the probability of rolling a one on all six dice is:

(1/6) * (1/6) * (1/6) * (1/6) * (1/6) * (1/6) = (1/6)^6

So the probability of all six dice showing a one is 1/46656

Answer:

Step-by-step explanation: The equation that models the final balance A given principal P and time t is:A = P(1 + 0.077)^tTo find the equivalent monthly interest rate, we need to find the rate that when compounded monthly gives the same final balance as the annual rate of 7.7% compounded annually.First, we know that 1 year has 12 months, so we can find the number of months in t years by multiplying t by 12.Let's call this number of months n.n = t*12Next, we can use the property of exponents that (a^b)^c = a^(bc) and rewrite the equation as:A = P(1 + 0.077)^(n/12)Now we can find the monthly rate (r) by dividing the annual rate by 12r = 0.077/12 = 0.006416666666666666In percentage form, the equivalent monthly interest rate is approximately 0.64 %

The true statements from the given statements are : 'If 7 is an odd number, then February does not have 30 days.' and 'If 7 is an even number, then January has exactly 28 days.'

Therefore the answer is (c) and (d).

(a) False. February does not have 30 days, it has 28 or 29 days (in a leap year). The statement is false, because 7 being an odd number has no connection to the number of days in February.

(b) False. January has 31 days, but 7 is an odd number.

(c) True. 7 is an odd number, and February has 28 or 29 days, but never 30 days.

Using Compound Interest, The largest balance is $780255, so the option A will give them the largest balance after 5 years.

Even though there are several ways to define an investor, compound interest helps investors. When banks lend money and utilize the income they earn to finance other loans, for instance, they profit from compound interest. When depositors earn interest on their bank accounts, bonds, or other investments, compound interest benefits them.

It's crucial to remember that although while "compound interest" includes the word "interest," the idea extends beyond the contexts in which the expression is typically employed, such as bank accounts and loans.

We will calculate compound interest in every case:

Using formula

[tex]Amount = P(1 + \frac{r}{m})^{t}[/tex]

option A: balance after 5 years:

[tex]5,000 (1+ 2 \frac{1}{4}\%) ^{4\times 5} = $7802.55[/tex]

option B:

The momentum of an object is 50 kg m/s and the kinetic energy of an object is 250 Joules.

In contrast to momentum, which is an object's size in motion, kinetic energy is the energy that any material has as it speeds. The relationship between kinetic energy and momentum exists because of how they relate to mass and velocity.

By using the following formula:

Momentum = mass x velocity, we will find the momentum of an object.

Substituting the values of mass and velocity,

Momentum = 5 km x 10 m/s

Momentum = 50,000 kg m/s

Kinetic energy = ½ x mass x (velocity)2

Kinetic Energy = ½ x 5 km x (10 m/s)2

To divide decimals, you can follow these steps:

1.  Move the decimal point in the divisor (the number you're dividing by) to the right, counting the number of places you move it.

2. Move the decimal point in the dividend (the number you're dividing into) the same number of places to the right.

3. Divide the numbers as if they were whole numbers.

4. Place the decimal point in the quotient (the result) the same number of places from the right as the number you counted when moving the decimal points in step 1 and 2.

For example:

To divide 12.5 by 2.5, you would move the decimal point in 2.5 two places to the right to get 25, and move the decimal point in 12.5 two places to the right to get 1250. Then divide 1250 by 25 to get 50. Finally, place the decimal point two places from the right in the quotient 50 to get the final answer of 0.50.

Answer:

Neither.

Step-by-step explanation:

Parallel equations have the same y-intercept. Perpendicular equations have negative reciprocal slopes.

First, turn x-y=9 into y-intercept form.

(-y = 9 - x)-1

The equations are now

y = x-9 and

y= -5x+1 

They don't share the same y-intercept nor do they have negative reciprocal slopes, so it's neither.

Answer:

b. The money cannot be fully insured and earn annual interest of $39,740.

Simple interest is calculated by multiplying the principal deposited by the interest rate (in decimal form) and the time (in years).

Let x be the amount invested in the savings account that pays 12% simple interest and where deposits are insured to only $250,000.

Therefore:

As the total amount the student is investing is $390,000, the amount invested in the second account that pays 6.6% simple interest is (390000 - x).  Therefore:

To determine if the money can be deposited so that it earns annual interest of $39,740, equate the sum of the two expressions for interest to $39.740 and solve for x:

[tex]\begin{aligned}0.12x+0.066(390000 - x)&=39740\\0.12x+25740-0.066x&=39740\\0.054+25740&=39740\\0.054&=14000\\x&=259259.26\;\sf(2\;d.p.)\end{aligned}[/tex]

As x is not less than or equal to $250,000, it is not possible to deposit the money so that it is fully insured and earns the desired interest.
