Answer:

12x^4y^7

Step-by-step explanation:

base(b)=8x^3y^5

height(h) =3xy^2

Area= (b x h)/2 =12x^4y^7

Answer:

[tex]A = 12x^4y^7[/tex]

Step-by-step explanation:

The formula for the area of a triangle is:

[tex]A = \dfrac{1}{2}bh[/tex]

where [tex]b[/tex] is the length of the triangle's base and [tex]h[/tex] is the length of the triangle's height.

In this problem, we are given the length of the base of the triangle as [tex]8x^3y^5[/tex] and the length of the height of the triangle as [tex]3xy^2[/tex].

Thus, the area of the given triangle is:

[tex]A = \dfrac{1}{2} \cdot 8x^3y^5 \cdot 3xy^2[/tex]

We can simplify this by combining like terms and using the exponent addition rule ([tex]x^a \cdot x^b = x^{a+b}[/tex]).

[tex]A =\left(\dfrac{1}{2} \cdot 8 \cdot 3 \right)(x^3 \cdot x)(y^5 \cdot y^2)[/tex]

[tex]A = (4 \cdot 3)(x^{3 + 1})(y^{5+2})[/tex]

[tex]A = 12x^4y^7[/tex]

Answer:

sum of their present ages is 5 + 20 = 25 years.

Step-by-step explanation:

The father's current age is 4x (because he is four times as old as his son)

Five years ago, the father's age was (4x - 5) and the son's age was (x - 5)

Ten years from now, the father's age will be (4x + 10) and the son's age will be (x + 10)

From the second statement, we know that:

(4x - 5) = 1.5(x - 5)

And from the third statement, we know that:

(4x + 10) = 1.5(x + 10)

We can solve these equations simultaneously to find the present ages of the father and the son.

Solving the first equation:

4x - 5 = 1.5x - 7.5

2.5x = 12.5

x = 5

So the son's current age is 5 years old.

The father's current age is 4x = 4(5) = 20 years old.

So, the sum of their present ages is 5 + 20 = 25 years.

Use A Budgeting Calc This Anwser Is Correct

If Jennifer wants to use the money to buy a new bicycle in 2 years, she can spend (future value) $388.54 on the bike as the account earns 13% interest, compounded monthly.

Compound interest is a system of interest computation where interest accumulates on the principal and previously accumulated interests.

Compounding the present value means adding interest to the principal amount when calculating subsequent interests.

N (# of periods) = 24 months (2 years x 12)

I/Y (Interest per year) = 13%

PV (Present Value) = $300

PMT (Periodic Payment) = $0

Results:

Future Value (F) = $388.54

Total Interest = $88.54

Thus, with a deposit of $300, Jennifer can spend $388.54 after earning 13% monthly compounded interest.

What is inverse function?

A function that returns the initial value for which a function has produced output is called an inverse function. If f(x) is a function that produces the value y, then f-1(y), which is the inverse function of y, will produce the value x. Inverse and reciprocal functions should not be confused. The output's original value is returned by the function's inverse, represented by the symbol f-1 (x). While the reciprocal of a function is represented by 1/f(x) or f(x)-1

Those that do are referred to as invertible. For a function f: X Y to have an inverse, it must possess the characteristic that there is exactly one x in X such that f(x) = y for every y in Y. This characteristic guarantees the existence of a function g: Y X that has the required connection to f.

The trip would have taken 8.89 hours instead of 8 hours.

Distance traveled can be calculated by multiplying the speed at which the object is traveling by the amount of time the object has been in motion.

For example, if a car is traveling at 60 miles per hour for two hours, the distance traveled would be 120 miles.

To calculate distance more accurately, you can use the formula d = rt, where d is the distance, r is the rate of speed, and t is the time in which the object has been in motion.

It is important to note that this formula assumes a constant speed throughout the duration of the journey.

It is also important to remember that the unit of measurement used for both the speed and the time must be the same. Therefore, if the speed is in miles per hour, the time must also be in hours.

In order to calculate this, we need to first calculate the time it took for the family to travel the first 600km at 90km/h. This can be calculated using the formula:

Time = Distance / Speed

So, the time it took for the family to travel the first 600km is:

Time = 600km / 90km/h = 6.67 hours

Then, we can calculate the time it would have taken for the family to travel 800km at 90km/h using the same formula:

Time = 800km / 90km/h = 8.89 hours

Therefore, the trip would have taken 8.89 hours, which is 0.89 hours longer than the original trip which took 8 hours.

Compound interest is interest that is paid on both principal and interest at regular intervals. The first year of compound interest is similar to the first year of simple interest, but the difference begins in the second year.

Continuously compounded interest means that an account balance is constantly earning interest and reinvesting that interest so that it, too, earns interest.

Given that Jessica invests $3,065 in a savings account with an annual interest rate of 5% compounded continuously.

The account balance after 5 years will be calculated as:-

The sampling distribution of the sample mean based on samples of size 2 for a population can be approximated by a normal distribution.

The histogram of the sampling distribution would therefore look like a bell-shaped curve. The mean of the sampling distribution is equal to the population mean, and the standard deviation of the sampling distribution is equal to the population standard deviation divided by the square root of the sample size (in this case, 2).

Therefore, the formula for the sampling distribution of the sample mean for a population of size 2 is:

Mean = Population Mean

Standard Deviation = Population Standard Deviation / √2

The histogram of the sampling distribution would look like a bell-shaped curve with the mean and standard deviation determined by the formula above.
