Mrs.Kunkleman asks her students to write the Pythagorean theorem in their own words
masha68 [24]

Step-by-step explanation:

The Pythagorean theorem can be understood as a mathematical relationship between the sides of a right triangle that helps to understand geometric problems in real situations, such as finding measurements, calculating areas, etc.

The theorem says that the square of the hypotenuse is equal to the sum of the squares on the other sides.

In a right triangle the hypotenuse is the longest side of the triangle, on the side opposite to its longest angle, and the other two sides will be the sides. So the Pythagorean theorem formula is:

a² = b² + c²

where a represents the hypotenuse and b and c the other sides.

If f(x)= 3 over x+2- square root x-3 f(19)=
PSYCHO15rus [73]
F(19)= (3/(19+2)) - sqrt(19-3)
= (3/21) - sqrt(16)
= (1/7) - 4
= (1/7) - (28/7)
= -27/7
= - 3 6/7

NEED ANSWER ASAP PLEASE WILL GIVE BRAINLIEST An integer n is divided by 2 and the quotient is an even integer. What does this te
Nesterboy [21]

Answer:

n is a multiple of 4

Step-by-step explanation:

Let's think about this.

Even numbers are basically numbers that, when divided by 2, get us an integer.

This means that n must be an even integer.

<em>However,</em>

Every other even number, when divided by 2, gets you an odd integer.

This means that every second even number, n \div 2 gets us an even number.

This also means that every time n \div 2 is an even number, n will be a multiple of 4 (as 2\cdot 2 = 4).

Test this out with any even number that's a multiple of 4 (all multiples of 4 are even numbers)

Hope this helped!

Help me please I don't know how to do this.
djyliett [7]
Hey there.

If the decimal point is .500 and up, we will be rounding up. If it is .499 and lower, we will be rounding down.
Now let’s look at the numbers.
2.500 g can be rounded up, so we’ll make that 3.000 g.
5.000 g is going to stay the same, since the decimal point is .000
2.268 g will be rounded down, making it 2.000 g
5.670 will be rounded up and will become 6.000 g
And finally, 11.340 g will be rounded down to 11.000 g.

Hope this helps!

Lynna [10]
We have ( 8 + 4 )/ 2 = 12/2 = 6;
(-2 - 6 ) / 2 = -8 / 2 = -4;
The midpoint is (6,-4);
