Answer:
- vertex: (-5/8, 7/16)
- axis of symmetry: x = -5/8
Step-by-step explanation:
For quadratic ax²+bx+c, the axis of symmetry is located at x=-b/(2a).
Here, we have a=4, b=5, so the axis of symmetry is ...
... x = -5/(2·4) = -5/8
_____
The vertex y-value will be f(-5/8).
... f(-5/8) = (4·(-5/8) +5)·(-5/8) +2 = (5/2)·(-5/8) +2 = -25/16 +32/16
... f(-5/8) = 7/16
_____
The axis of symmetry is x = -5/8; the vertex is (-5/8, 7/16).
Swap yards to feet 3 feet= 1 yard so you end up with 45 feet x 66 feet at that is 2,970 so you will end up with 2,970 feet in area and 35,640 inches.
Answer: length = 6 and breadth = 3.
Step-by-step explanation:
For perimeter,
2(l+b) = 18
For area,
l*b = 18
Solve these equation and you'll get answer.
LW = A
L(L - 3) = 18
L^2 - 3L - 18 = 0
(L - 6) (L + 3) = 0
L could be 6 or -3 ( -3 cannot be a length of a side of a rectangle since it’s negative.)
So L = 6 and W= 3
3/4 x 1 = 3/4 x / = 21/28
?/? = 7/7
