Answer:
is a way to express the definition of a circle on the coordinate plane.
Step-by-step explanation:
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. Then complete the square for the y terms.
Answer:
h=5
Step-by-step explanation:
10+38h=200
-10 -10
38h=190
divide 38 from each side
h=5
Hello!
As you can see, 3x+9 makes a right angle, or 90 degrees. We can turn this into an equation and solve for x.
3x+9=90
First we subtract 9 from both sides.
3x=81
Then divide both sides by 3.
x=27
Therefore, x=27.
I hope this helps!
EXPLANATION
The nth term of the sequence is given by
Where
is the first term and
is the constant difference.
We were given that,
S we just need the common difference to write the nth term.
We can get that from another information given to us.
We were also given that the 4th term is 6. This gives the equation.
We substitute
to obtain
Or
This implies,
We substitute these values into the general formula to obtain,
This gives us,
Hence the nth term of the sequence is,
