Answer:
x ≈ - 5.83 , x ≈ - 0.17
Step-by-step explanation:
x² + 6x + 1 = 0 ( subtract 1 from both sides )
x² + 6x = - 1
Using the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(3)x + 9 = - 1 + 9
(x + 3)² = 8 ( take square root of both sides )
x + 3 = ± 
( subtract 3 from both sides )
x = - 3 ±
Then
x = - 3 - ≈ - 5.83 ( to 2 dec. places )
x = - 3 + ≈ - 0.17 ( to 2 dec. places )
Average rate=(change in y)/(change in x)
if f(x)=-x/3
r=( f(2)-f(-2) )/(2--2)
r=(-2/3-2/3)/(2+2)
r=(-4/3)/4
r=-4/12
r=-1/3
For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.
Answer:
56.52
Step-by-step explanation:
1. multiply your r by 2
so 9*2= 18
2. multiply that by pi, which you substitute 3.14 in for
so 18*3.14=56.52
Answer:
It is impossible to draw two different triangles with these criteria.
Step-by-step explanation:
The 3,4,5 triangle is a Pythagorean triplet, but if it was said to be 6,8,10, then yes two different triangles can be made, same with any other multiple of a 3,4,5 right triangle. The 3,4,5 triangle is in its reduced form causing there to be no other triangles that can be made that still function as a triangle through the theorem of triangles where the hypotenuse has to be bigger than either side length.
