First, we have to realize that this is factored form, so we have to put this in standard quadratic form using FOIL, which is a rule mandating how we multiply the numbers here. F stands for First, which means the first number inside the parentheses for both of them, then O means the first number in the first quantity(fancy word for parentheses) multiplied by the last number of the second quantity, and so forth. When you are done, you combine like terms
anyway, you end up with x²-12x-189, but you have to inverse all numbers because of the parentheses in front, so it becomes -x²+12x+189.
Now you can find the axis of symmetry uisng the equation -b=2a (oh yeah, I forgot to mention: the standard quadratic form is a(x)²+b(x)+c already). So you do -12 / -2, which then becomes 6.
The axis of symmetry is 6
Answer:
For an ordered pair (x,y) that a set contain :
x = Domain of the relation
y = Range of the relation
In a relation x can have two or more than two ranges i.e a x can have more or more than two images.
So, Domain = First element of ordered pair that the following relation R contains ={(−3, 4), (5, 0), (1, 5), (2, 8), (5, 10)}= -3, 5, 1,2,5
But the element 5 is Occuring twice.
Domain = { -3,1,2,5} →→Option A
<span>False.
Experimental probability is based on doing trials.</span>
Answer:
Steps shown below
Step-by-step explanation:
We will simplify this using definitions and identities. Let's start.
Using , we have:
Using , we have:
Hence, proved.
The vertical asymptote is r = 0. The intensity is undefined at the source. The horizontal asymptote is I = 0. As the distance from the source increases, the intensity goes to zero. The intensity decreases as the distance increases.
