The equation of a circle uses the following formula:
The center of the circle is given by (h,k). Therefore, h = -2, and k = -5. r = 1, so we can find the equation from the information given to us.
Plug in your values.
The equation of this circle is as follows:
Answer:
2.6 x 10^21
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Step-by-step explanation:
w=5 L=7
w=5+x. L=7+x
A = w*L
= (5+x)* (7+x)
=35+5x+7x+x^2
=x^2+12x+35
Answer:
y=3x-4
Step-by-step explanation:
Lets make this into y=mx+b form
m(slope)
b(y intercept)
y=3x+b
Now plug in 2 for y and 2 for x (since the coordinantes are 2,2)
2=3(2)+b
Simplify like terms
2=6+b
-4=b
So b=-4 and m=3.
You got your equation, y=3x-4
Given that sample standard deviation is zero. This indicates that the variance of sample is also zero as square of sample standard deviation is sample Variance. Variance is average of the squared deviations from mean. As shown in below formula
Since Variance = 0 , we substitute in formula and we get the sum of squares of deviations of all data points from mean should be zero. This is only possible if and only if all the data points in the data distribution are same as mean of the data distribution. In the case the variance and standard deviation will be zero.
Variance = Summation n to i = 1
0 = Summation n to i = 1
Summation n to i = 0
