Answer: x1=1 x2=-2 and x3=2
Step-by-step explanation:
1st x1=1 is 1 of the roots , so
F(1)=1-1-4+4=0 - true
So lets divide x^3-x^2-4x+4 by (x-x1), i.e (x^3-x^2-4x+4) /(x-1)=(x^2-4)
x^2-4 can be factorized as (x-2)*(x+2)
So x^3-x^2-4x+4=(x-1)*(x^2-4)=(x-1)(x-2)*(x+2)
So there are 3 dofferent roots:
x1=1 x2=-2 and x3=2
To convert 1.3 miles into inches we proceed as follows;
1 mile=63360 inches.
Therefore the number of inches in one mile will be as follows:
(1.3*63360)
=82,368 inches
Therefore, we conclude that our answer is 82,368 inches.
Answer:
2.89 rounded is 3 2.82 rounded is 2.80 which = 2.8 you minus 3-2.8 it = 0.2
Step-by-step explanation:
Answer:
y = 1/3x + 1
Step-by-step explanation:
- find the slope by using y2-y1/x2-x1
4-3/9-6
1/3. slope = 1/3 = m
2. plug the values into the equation to find y-int. You can use whichever point is given to you
I'll use (6,3)
y = mx + b
3 = 1/3(6)+b
1/3(6)=2
3 = 2 + b
3. subtract 2 from both sides and you get b
b = 1
So, the equation of the line would be
y = 1/3x + 1
Answer:
(x - 3)² + (y + 4)² = 49
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + *y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (3, - 4) and r = 7 , then
(x - 3)² + (y - (- 4) )² = 7² , that is
(x - 3)² + (y + 4)² = 49 ← equation of circle
