x=11.5 i think
Step-by-step explanation:
Answer:
70123214.6cm^2
Step-by-step explanation:
Lets just choose the first one, 3 4 and 5. According to the Pythagorean Theorem,
a^2+b^2=c^2
So lets plug in our numbers.
3^2+4^2=c^2
The answer should be 5, but lets make sure.
3*3 = 9
4*4 = 16
9+16=c^2
25 = c^2
Square root both sides so:
5=c
And sure enough 5 is the last number on that list. The order doesn’t matter as long as the value you are trying to find is the c^2.
For this case we have a quadratic equation of the form:

What we must keep in mind to know which direction opens the parabola, is the value of a.
We have two options:
If a <0 the parabola opens down
If a> 0 the parabola opens up
We have the following equation:

We observed that:

Therefore, the parable opens up.
Answer:
the direction that this parabola opens is:
Upwards
2 equal angles is the correct answer
