Answer:
1 . -9 = 0
2 . x = 0
3 . 0 = 0
4 .x = -27
5 . x = -4
Step-by-step explanation:
Let's assume that the parabola has the following intersections with the x axis:
x1 = p
x2 = q
To find the equation of the parabola, we write the following product of binomials:
(x-p) (x-q) = 0
Where,
p, q: intersections with the x axis.
When developing the product of binomials, we obtain the equation of the parabola.
Answer:
(x-p) (x-q) = 0
Answer:
Explanation:
H(t) = -2/5t - 5
-2/5t - 5 = 0
-2/5t = 5
t = 5 x -5/2
t = -25/2
Step-by-step explanation:
The rectangle area is equal to LENGTH * WIDTH
then
t^2-16t+48 = L*W
L = [t^2-16t+48] / W
and
t^2-16t+48 = L*W
W = [t^2-16t+48] / L

Answer:
30.594
Step-by-step explanation:
To find perimeter we need to find the length of all the sides
The coordinates are A(-3,4), B(7,2), C(6,-3), D (-4,-1)
To find the length of side , we use distance formula
Side 
Side 
Side 
Side 
To find perimeter we add all the sides
10.198 + 5.099 + 10.198 + 5.099= 30.594
the perimeter of the rectangle= 30.594
