We are given with a equation of Circle and we need to find it's radius and it's equation in standard form . But , let's recall , the standard equation of a circle is where <em>(h,k)</em> is the centre of the circle and radius is <em>r</em> . Proceeding further ;
Collecting <em>x</em> terms , y terms and transposing the constant to RHS ;
Now , as in standard equation their is a whole square , so we need to develop a whole square in LHS , for which we will use completing the square method , as coefficient of x² and y² is 1 , so adding 121 and 36 to LHS and RHS .
On comparing this with the standard equation , we got our centre at <em>(-11,-6)</em> and radius is <em>18 units </em>
Answer:
12/20
60%
Step-by-step explanation:
A fraction has a numerator and denominator
The numerator is the total number of heads
The denominator is the total number of times the coin was flipped
To express in percent form, multiply by 100
x 100 = 60%
Answer:
C
Step-by-step explanation:
The answer is c because there is only one answer for the question.
Simple,
You have 11
to change it into an improper fraction multiply the
whole number (11) by the
denominator (8)
11*8=88
Then,
add the numerator to what you have multiplied..
88+5=93
Finally,
use the original denominator....Making your answer...
Thus, your answer.
Okay, it's very simple, to solve this triangle you need to understand what the other angles are. We know that angle A is 90º, as it is represented as a square.
We now need to solve for angle B. angle B can be solved for by
Sin (x) = Opposite / Hypotenuse = 3 / 3√5 = 2.24ish
sin(x) = 2.24
x = (2.24)
Use sin.
