Answer:
52.5
Step-by-step explanation:
The area of a triangle is base * height / 2, or in the case of a right triangle (like this), the legs multiplied by each oehter then halved is the area.
(10 * 10.5) / 2 = 52.5
Answer:
By putting x = -x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Step-by-step explanation:
We need to explain why the function of
is neither even or odd
First we will understand, when the function is even and odd
Even function:
<em>A function is even if f(-x) = f(x) </em>
Odd function:
<em>A function is odd if f(-x) = -f(x) </em>
So, if we get the above result by putting x = -x, then we can say that the function is even or odd.
If we don't get any of the above results then the function is neither even nor odd.
So, for the given function: ![f(x)=4x^2+8x](https://tex.z-dn.net/?f=f%28x%29%3D4x%5E2%2B8x)
Put x = -x
![f(x)=4x^2+8x\\Put x=-x\\f(-x)=4(-x)^2+8(-x)\\f(-x)=4x^2-8x](https://tex.z-dn.net/?f=f%28x%29%3D4x%5E2%2B8x%5C%5CPut%20x%3D-x%5C%5Cf%28-x%29%3D4%28-x%29%5E2%2B8%28-x%29%5C%5Cf%28-x%29%3D4x%5E2-8x)
So, by putting x=-x in f(x) i.e. f(-x) we didn't get f(x) or -f(x) so, the function is neither even nor odd.
Answer:
Order of Operations.
Step-by-step explanation:
If we include -7 in the parenthesis, the exponent acts the negative as well. Therefore:
(-7)²= 49.
However, when squaring without the parenthesis, it will give us a negative number because:
The order of operations, or PEMDAS, states that exponents come before multiplication. Therefore, when doing '-7²', you would first need to square the '7', giving us:
-7² = -49
However, within parenthesis, everything inside will be squared.
