2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
The standard equation of a circle is given by:
(x-a)²+(y-b)²=r²
where:
(a,b) is the center and r is the radius.
Given that (a,b) is (-8,-3) and r=2 units
then the equation of the circle will be:
(x-(-8))²+(y-(-3))²=2²
simplifying the above we get:
(x+8)²+(y+3)²=4
0=65-10t-5t^2
now what you want to do is multiply a and c
-5(t^2+2t-13)
Now just find the zeros
Answer:
70.56
Step-by-step explanation:
The variance is the standard deviation squared.
σ² = (8.4)² = 70.56
