Answer:

To find an ordered pair (x, y) that is a solution to the equation -x + 2y = 7, we can substitute any values of x and y that satisfy the equation. For example, let x = 3, then we can solve for y:

-3 + 2y = 7

2y = 10

y = 5

So (3, 5) is an ordered pair that is a solution to the equation.

The correct question is:

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

Kinetic Energy = 250 J

The total population of the wolves after 2 years will be 500 + 125 = 625 wolves

a) After 1 year, the number of wolves in the forest will increase by 25% of the current population, which is 400 wolves.

The increase in population is equal to 0.25 * 400 = 100 wolves

The total population after 1 year will be 400 + 100 = 500 wolves

b) After 2 years, the number of wolves in the forest will increase by 25% of the population from the previous year, which is 500 wolves.

The increase in population is equal to 0.25 * 500 = 125 wolves

The total population after 2 years will be 500 + 125 = 625 wolves

Answer: READ BELOW

Step-by-step explanation:

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.

The standard matrix A is [ (1/2, √3/2) (√3/2, -1/2) ]

To find the standard matrix of a linear transformation, we need to find the images of the standard basis vectors under the transformation.

The standard basis vectors in R2 are (1,0) and (0,1). Let's find their images under T.

The image of (1,0) under a 30∘ clockwise rotation is (√3/2, 1/2). The image of this under reflection through the line y=x is (1/2, √3/2).

The image of (0,1) under a 30∘ clockwise rotation is (-1/2, √3/2). The image of this under reflection through the line y=x is (√3/2, -1/2).

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%

Answer:

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

Step-by-step explanation:

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.
