5 * root(x ^ 2, 3) is the equivalent expression.

Why do roots grow in numbers?

Simply multiplying the radicands and placing the result behind the radical sign is all that is required to multiply two square roots. The square root of the product of the radicands, in other words, is equal to the product of two square roots.

Only if the numbers under the radical sign are equal can you add or subtract square roots themselves. The original number will still be in the radical sign after adding or subtracting the coefficients (numbers in front of the radical sign). Implement the suggested action.

The inequality that represents the situation is

Answers

The inequality that represents the situation is 45x + 1240 ≥ 6000

There are 45 members overall.

If one individual contributes $x, then

The sum that 45 individuals together raised is then equal to 45x.

$6000 is the bare minimum necessary to enter the competition.

$1240 is the amount they already have.

Therefore, the amount they need to raise is $6000 minus $1240.

Inequality can be displayed as:

What is 1 mole equal to grams?

Answers

Therefore, one mole of any substance is equal to its molar mass in grams.

Define molar mass.

Mass per mole is a definition of molar mass. In other terms, molar mass is the total mass of all the atoms in a material that makes up a mole. It is measured in gram-per-mole units.

What are atoms?

A chemical element is uniquely defined by its atoms, which are tiny pieces of substance. An atom is made up of a core nucleus and one or more negatively charged electrons that orbit it. The positively charged, comparatively hefty protons and neutrons that make up the nucleus may be present.

The molar mass of a substance is the mass of one mole of that substance and is usually expressed in grams per mole (g/mol).

For example, the molar mass of carbon is 12.01 g/mol, so one mole of carbon weighs 12.01 grams.

Therefore, one mole of any substance equals its molar mass in grams.

It is essential to mention that the molar mass is the weight of one mole of a substance and is determined by the atomic or molecular weight of the substance.

Item 48 A couple has 5 children, all sons. If the woman gives birth to a sixth child, what is the probability that the sixth child will be a son

Answers

The probability that the sixth child will be a son is 50%. Each child, regardless of gender, has an equal chance of being born.

What is the probability that the sixth child will be a son?The probability of having a son as the sixth child can be calculated using the binomial formula. The binomial formula is used to calculate the probability of an event occurring after a certain number of trials, given the probability of success in each trial.In this case, the probability of having a son is the same for each trial (or birth), which is 0.5 (since the odds of having a boy or a girl are equal).Therefore, the probability of having a son as the sixth child can be calculated as follows:

P(son) = (5 choose 6) x (0.5^6) = 0.015625

Angle of elevation: In 2001, the tallest building in the world was the Petronas Tower in Kuala Lumpur, Malaysia.

7. Kya picks up where she left off in her book and starts reading. After 2 hours, she's on page 195. After reading for 4 hours that day, she's on page 297. Write an equation to represent how many pages Kya reads per hour.

I did the equation= y=51x+93

There are a total of 399 pages in the book. How many more hours does Kya have left to read? PLEASE HELP WILL THIS PART I DONT UNDERSTAND ​

Answers

Answer:

Step-by-step explanation:

Work for finding the equation, feel free to skip it:

So first off, to write the equation, we will use an equation in slope intercept form: y = mx + b, where y is the numbers of pages she has read, m is the number of pages she reads per hour, x is the number of hours she read, and b is the number of pages she has already read.

To find the slope(The number of pages she reads per hour), we can subtract the number of pages she had read at 2 hours from the number of pages she had read at 4 hours:

297 - 195 = 102.

This tells us she read 102 pages over 2 hours. Thus, over 1 hour, she had read 102/2 = 51 hours. This is m. So our equation so far is y = 51x + b

To find b, we can take 195(the pages she had read after 2 hours), and subtract it by the pages she can read over 2 hours(51 * 2), giving us the amount of pages she had already read(b):

195 - (51*2) = 195 - 102 = 93.

So our equation is:
y = 51x + 93.

Work for finding how many hours it will take Kya to read the whole book:

Y is the total number of pages Kya has read when we plug in x hours. However, if we already know the total number of pages in a book, we can plug in that number for Y, and then solve for x to find how many hours it takes for Kya to read the book:

399 = 51x + 93

Subtracting 93 from both sides gets us:

51x = 306

=

x = 6

This means it takes 6 hours for Kya to read the whole book.

Since Kya has already been reading for 4 hours, the time she has left is:

6-4 = 2

So it takes Kya 2 more hours to finish reading the 399 pages in the book.

x =√ 9.000 = -3.00000 or :

x =√ 8.000 = 2.82843 or :

x =√ 8.000 = -2.82843

Four solutions

Answer:

x^4 - 17x^2 + 72 = (x^2 - 9)(x^2 - 8)

Step-by-step explanation:

First, we need to find two numbers that multiply to give us 72 and whose sum is -17. We can see that 8 and 9 multiply to give us 72, and their sum is 8 + 9 = 17. Since we want the sum to be negative, we need to change one of the signs. So we write -(8 + 9) = -17.

Next, we write the expression as the product of two binomials. We factor out the common factor x^2 from the first two terms: x^4 - 17x^2 + 72 = x^2(x^2 - 17) + 72

Now, we complete the square in the first binomial. To do this, we need to add and subtract (17/2)^2 = (8.5)^2 = 72.25 inside the bracket:

x^2(x^2 - 17) + 72 = x^2(x^2 - 17 + 72.25 - 72.25) + 72 = x^2(x^2 - 17 + 72.25) - 72.25 + 72

Now we can rewrite the square of a binomial :

x^2(x^2 - 17 + 72.25) = x^2((x-8.5)^2)

Finally, we can combine the two binomials

x^2((x-8.5)^2) + 72 = (x^2(x-8.5)^2) + 8(9)

So the expression x^4 - 17x^2 + 72 factors completely as (x^2 - 9)(x^2 - 8)

A grocery store has increased its prices over time. The price per pound of apples in 2016 was $0.45. Today, the price per pound of apples is $0.85.
What is the equation of the line that would represent the price increase per pound of apples over time?

Answers

Answer:

C = 0.06x + 0.45

Step-by-step explanation:

Today is 2023

So, from 2016 to 2023, it has been 7 years.

0.85 - 0.45 = $0.40

So, $0.40 is the increase in 7 years

0.40 / 7 = $0.06

So, $0.06 is the change per year

Let C represent the total cost and x represent the number of years and we have

C= 0.06x + 0.45

The tree is ___ meters high. Round your answer to the nearest tenth and write it as a decimal.

Answers

Answer:

The tree is 9.1 meters high.

Step-by-step explanation:

We can use the Pythagorean Theorem to solve this problem. Let T be the height of the tree. We can set up the following equation:

4.2^2 + T^2 = 6.5^2

Solving for T, we get:

T = sqrt(6.5^2 - 4.2^2)

T = sqrt(41.25 - 17.64)

T = sqrt(23.61)

T = 4.878

Since the height of the tree is measured to the nearest tenth, we can round this value to 9.1 meters.

Find the inverse of y = √x + 8, y ≥ 8

Answers

To find the inverse of a function, you can follow these steps:

Swap the variables x and y in the original function. For example, if the original function is y = √x + 8, you would swap the variables to get x = √y + 8.

Solve the equation for y. In this case, you would get:

x = √y + 8

y = x - 8

Replace y with f^-1(x) to denote the inverse function. The inverse function is defined as f^-1(x) = y, so you would get:

f^-1(x) = x - 8

This is the inverse function of y = √x + 8.

Note that the inverse function is only defined for values of x such that y ≥ 8. This is because the original function y = √x + 8 is only defined for y ≥ 8.

Answers

Answer: y = 14x - 81.

Step-by-step explanation:
1. Since the lines are parallel to each other, that means they have the same slope, which is 14.
2. To find the equation of line q, you would need to use the point-slope equation, which is y2 - y1 = m (x2 - x1) and input the values of point (6, -3).
3. The equation you need to solve after inputting values would be y + 3 = 14 (x - 6).
4. Simplify the equation by distributing 14 into the parentheses. This would give you y + 3 = 14x - 84.
5. Now, subtract 3 on both sides to get the y alone. This should give you y = 14x - 81.
