Step-by-step explanation:

The equation which is a radical equation from the given answer choices is; 7 √x = 14.

In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x: {\displaystyle r^{n}=x, } where n is a positive integer, sometimes called the degree of the root. A root of degree 2 is called a square root and a root of degree 3, a cube root.

here, we have,

According to the task content;

It follows that we are required to determine the equation which is a radical equation.

here, we have,

given that,

we have to find the radical equation.

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(6,7) and B(-5,-9)

The midpoint is

[tex]M = ( \frac{6 - 5}{2} \: , \: \frac{7 - 9}{2} ) \\ = ( \frac{1}{2} \: , \: - \frac{2}{2} )[/tex]

We have the final answer as

8 3/4 chores

Step-by-step explanation:

Answer:

37 is the smallest positive integer n such that n(n+1)(n+2) is divisible by 247.

Step-by-step explanation:

First we will find the prime factors of 247:

247 = 13 x 19 (which are both prime).

So now we need to find a number (the smallest one) that is of the form (n)(n+1)(n+2) (the product of three consecutive numbers) and that is divisible by both 13 and 19 (and therefore divisible by 247)

Let's take a look at the multiples of 13: 13, 26, 39, 52...

Let's take a look at the multiples of 19: 19, 38, 57...

We can see that the first time we have two multiples close together are the 38 (for 19) and the 39 (for 17).

So, if our number has both 38 and 39 as factors, then it will be divisible by 247.

However, we need not two but three consecutive numbers, and since we want the number to be the smallest positive integer, we will add 37 (since our other choice would be to add 40 and that would make the number bigger) and thus our number is (37)(38)(39) or in other words (37)(37 + 1)(37 + 2) and therefore this is the smallest positive number such that n(n+1)(n+2) is divisible by 247.

The smallest positive integer n such that n(n+1)(n+2) is divisible by 247 is 37.

n(n+1)(n+2) is divisible by 247

Then, n(n+1)(n+2) =247k, where k is an integer

so, [tex]k = \frac{n(n+1)(n+2)}{247}[/tex]

An integer is a number that is not a fraction but a whole number.

Since the prime factors of 247 are 19 and 13.

By hit and trial let us choose the value of n such that n *(n+1) or (n+1) *(n+2) or n *(n+2)  become the multiples of 19 *13.

If n = 37

n+1 = 38

n+2 = 39

So, if n=37, ( n+1 )*(n+2) will get divided by 19*13

So, the smallest possible integer 'n' will be 37.

Therefore, the smallest positive integer n such that n(n+1)(n+2) is divisible by 247 is 37.

Answer:

Step-by-step explanation:

This exercise desires to test our   knowledge of units conversion,

now, given that on the map 1 inch represents 4 miles

the distance of 1mile when converted to inches ordinarily would be

1mile is 63360 inches

since on the map

1 inch represents 4 miles

63360 inches represents  Xmiles

cross multiply we have

X would be = 63360*4

On a map one mile would be 253440 miles

Answer:

False

Step-by-step explanation:

A subset is a set whose elements belong to another set

If B is a subset of A, B would contain elements of A

For example,  A = {a, b, c} and if B is a subset of A , B = { a, b}

Step-by-step explanation:

F(x) =x^2

G(x) =x-3

G(f(x))

= (x^2) -3

F(f(x))

= (x-3)^2

(x-3)(x-3)

x^2 -6x+9

For the second one

1/(x-3)

x-3 ≠ 0

x ≠ 3

So the domain restriction = 3

Step-by-step explanation:

Answer:

Step-by-step explanation:

This is how to round 6.47 to the nearest tenth.

First note that 6.47 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 6

Fractional Part: 47

To round 6.47 to nearest tenth means to round the numbers so you only have one digit in the fractional part.

Answer:

median = 10

mean = 10.9

Step-by-step explanation:

These are the answers because:

1) Whenever, there is an even set of numbers for the median, you have to take the two middle numbers in the number set given and then add them. After you add them, you have to divide them by 2.

In this case, it would be:

10 + 10 = 20

20/2 = 10

2) 10.9 is the answer for mean because first, you need to add all the numbers in the set. If you add

8 + 8 + 10 + 10 + 10 + 12 + 13 + 16 you would get 87. Then, you have to divide by how many numbers there are in the number set. In this case it would be 87/8 which is 10.875

Once you round it, you will get 10.9
