Answer:
the second option
Step-by-step explanation:
in ax²+bx+c = 0:
subtract both sides by 6 to get to this form, as the right side will be left with 0
6x² + 8x - 6 = 0
here, the coefficient for x² (a) is 6, the coefficient for x (b) is 8, and the remaining number added on (c) is -6
plugging our numbers into the formula, we get
To solve this, we work out the volume of the two shapes (the cuboid and the pyramid) and then add them together.
We get the volume of the cuboid by multiplying the base by the width by the length:
Volume of cuboid = 6 x 6 x 4
= 144m³
Now to get the volume of the pyramid, we multiply the base by the length by the height, and then we divide by three.
Volume of pyramid = 6 x 6 x 8 ÷ 3
= 96m³

Answer:
Now that we know the two volumes, we simply add them together:
144 + 96 = 240m³
So the volume of the composite sold is 240m³
Being that the system is quadratic—with parabola opening downwards—you’re going to need to find the vertex. You can find the x coordinate of the vertex with -b/2a . Then plug in for x to find the y coordinate…
The answer should be a hope this helps :]
Answer:
Fourth option y = x²
Step-by-step explanation:
It is clear from the graph that parabola passes through origin, which is it's vertex and line of symmetry is y-axis.
So the equation of the parabola will be y = (x - 0)² + 0
This equation of the parabola is in the vertex form [ y = (x - h)² + k]
Therefore, equation of the parabola will be y = x²
This equation is true for the given values of x and y in the table.
For (-2, 4) ⇒ 4 = (-2)²
For (-1, 1) ⇒ 1 = (-1)²
Fourth option y = x² is the answer.
