Answer:
Step-by-step explanation:
y = -x^2+4x-6x +24
y = -x^2 -2x + 24
Vertex (x) = 2/-2 = -1
Vertex (y) = -100/ -4 = 25
Vertex (-1, 25)
axis of symmetry: x= -1
-x^2 -2x + 24 = 0
Δ/4 = 1+24 = 25
x1 = (1 + 5)/-1 = -6
x2 = (1-5)/-1 = 4
left x intercept = (-6,0)
right x intercept = (4,0)
The DOMAIN is the set of all numbers
The range is y less than or equal to 25
Answer:
2 belongs to A
Step-by-step explanation:
€ symbol means "belongs to"
Therefore 2 € A
We know that his woodshed is a parallelepiped, and 8' is the depth, 16' is the lenght and 6' is the height.
A cord of wood is 4' high, 4' deep and 96" long.
96" = 8'
We find the volume of his woodshield.
V = h*d*l = 168*6 = 768 cubic feet
Find the volume of a cord
4*4*8 = 128 cubic feet
Do the ratio: 768/128 = 6
His woodshield can hold 6 cords.
For the second question, simply do a multiplication.
If 1 cord is $120, how much are 6?
120*6 = $720
30/5=6+2=8
Eight would be the number
