What is the principal square root of 16

Mathematics

Your answer would be 4.

This is because the 'principal square root' means the positive square root of a certain number, and so √16 = 4 × 4, making 4 the answer. This has a certain term for it as √16 could equal -4 also (-4 × -4 = 16).

I hope this helps!

I need some serious help with standard form, Im really confused . Here's a problem ,
OLEGan [10]
I can see that the equation given above is a linear equation since y and x are the only variable and the degree is one. The standard form of a linear equation is written as:

Ax + By = C

We write the given equation into standard form as follows:

<span>y - 2 = 2(x - 3)
</span><span>y - 2 = 2x - 6
y -2x = -6 +2
y - 2x = -4
2x - y = 4</span>

Jose is thinking of a number.
alexira [117]

The number is 66.

Solution:

Let the number be x.

To find the number x using given conditions.

Start with the last condition.

It is less than 7 times 8 + 23 = 7 × 8 + 23 = 79

So, the number is less than 79 which implies x < 79.          

Using condition (4),  

It is greater than 5 times 4 = 5 × 4 = 20

So, the number is greater than 79 which implies x > 20.    

Combining condition (4) and (7), we get 20 < x < 79.

Using condition (3) and (5),

The number is a multiple of 11 and 6.

The number which is multiplied by both 11 and 6 is 66, 132, ...

But here x lies between 20 < x < 79.

So x = 66.

66 is not odd number and the sum of the digits is divisible by 2.

Therefore condition (1) and (2) also satisfied.

Hence the number is 66.

The square below has an area of 22 - 10.2 + 25 square meters.
ZanzabumX [31]

Answer:

x = 1.89

Step-by-step explanation:

Solve 22 - 10.2 + 25 to get 36.8 as the square's area.

Set up the equation 36.8 = (-10x + 25)^2 to represent the relationship between one side length and the area.

Reverse the equation to solve for x! Find the square root of both sides to cancel out the exponent. This gets you: 6.07 = -10x + 25.

Subtract 25 from both sides, then divide by -10 to get x by itself.

x = 1.89
