In any given right triangle, the Pythagorean Theorem can be used to show that it is a right triangle.

The Pythagorean Theorem is a^2+b^2=c^2. In a right triangle, a and b would be the shorter legs of the triangle, while c would be the hypotenuse.

So for this problem, you would plug in the numbers in the order that they are listed to see if it is a right triangle.

F would be: 2^2+4^2=7^2. In this case, the sides are not equal.

G would be: 6^2+8^2=10^2. In this case, 100=100. So this is a right triangle.

H would be: 4^2+9^2=12^2. The sides are not equal.

J would be: 5^2+10^2=15^2. The sides are not equal.

Your answer would be G, since the sides are equal. Hope this helps! :)

Tell whether the expression 3x^4 -5x +7 is a polynomial. If it is polynomial , find the degrees and determine whether it is a mo
ioda

Given:

The polynomial is:

3x^4-5x+7

To find:

The degrees and determine whether it is a monomial, binomial, or trinomial.

Solution:

We have,

3x^4-5x+7

The highest power of the variable <em>x</em> in the given polynomial is 4. So, the degree of the polynomial is 4.

Monomial: Polynomial with one term.

Binomial: Polynomial with two terms.

Trinomial: Polynomial with three terms.

In the given polynomial, we have three terms 3x^4,-5x,7. So, the given polynomial is trinomial.

Therefore, the degree of the polynomial is 4 and it is a trinomial.

How are dilations and functions related?
Anika [276]
If we dialate a function we are just changing what the graph looks like by a stretch or a compression, the function really doesn't change.  If a function before the dilation, then it is a function after the dilation.  The opposite is also true.
