Answer:
17.5 units
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem which states that a^2+b^2=c^2
Plug in what we know....
9^2+15^2=c^2
81+225=c^2
c=sqrt(306)
c=17.5
Answer:
True
Step-by-step explanation:
Only we can control ourselves, but if something is coming in our head and we want to think of something else we can. It could be hard for some but you can with effort
Hope this helps (:
Answer:
x = -1/2
Step-by-step explanation:
This question can be solved by applying the laws of indices
In a^n, a - base
n - index
Given
9^x = 1/3
According to the laws of indices, a/b = b^(-a)
Hence we can write, 1/3 = 3^(-1)
9^x = 3^(2x)
Again according to the laws of indices,
a^b = a^n can be written as;
b = n
That is, if in an equation the bases are the same, the indices are also equal.
So we can write,
3^(2x) = 3^(-1)
2x = -1
Divide both sides of the equation by 2, the coefficient of x
2x/2 = -1/2
x = -1/2
I think you mean what's the name of it,
they are called ordered points.
