Answer:
Step-by-step explanation:
Well we can start by seeing if the parabola is the same width by comparing it to its parent function ( y = x^2 )
In y = x^2 the 2nd lowest point is just up 1 and right 1 away from the vertex.
This is not true for our parabola.
So we can widen it by to the desidered width by making the x^2 into a .5x^2.
So far we’ve got y = .5x^2
Now the parabola y intercept is at -5.
So we can add a -5 into the equation making it.
y = .5x^2 - 5
Now for the x value.
So we can find the x value by seeing how far away the parabola is from from the y axis.
So the x value is -2x.
So the full equation is
Look at the image below to compare.
Given:
The shape is square.
To find:
The surface area and volume of a square.
Explanation:
The length of each side of the square is "a" units.
The formula for the surface area of the square is,
The formula for the volume of the square is,
Using these formulas, we can find the surface area and the volume of the square that has side length "a" units.
For example:
Let the side length of 3cm for a square.
So, the dimensions are 3cm by 3cm by 3cm.
That is,
The Length is 3cm.
The breadth is 3cm.
The height is 3cm.
So,
The surface area of the square is,
Therefore, the surface area of the square is 54 square cm.
The volume of the square is,
Therefore, the volume of the square is 27 cubic cm.
Answer:
Step-by-step explanation:
We want to determine an expression equivalent to:
Therefore:
It is x=8 because 13+7=20 and 28-20 would be 8 and that's the missing number.

<u>Explanation</u></h3>
Therefore, we have to make x-term as the subject of equation. Currently c-term is the subject of equation.
Isolate x and we get the answer.
