I'm confused on how to find x​

Mathematics
1 answer:
azamat2 years ago
7 0

Answer:

x = 2

Step-by-step explanation:

Since this is a 45-45-90 triangle, the 2 legs will be the same, meaning that y will also be \sqrt2.

We can then solve for x using the Pythagorean theorem:

\sqrt2^2+\sqrt2^2=x^2\\2+2=x^2\\4=x^2\\x=2

Or, we could use a quicker approach: if the triangle is a 45-45-90 triangle, the hypotenuse will be \sqrt2 times the length of 1 leg. It essentially does the same thing; it's just faster so you could save time on tests.

Answer:

5 terms

to the fourth degree

leading coeff of 1

3 turning points

end behavior (when x -> inf, y -> inf. When x -> - inf, y -> -inf)

x intercepts are (0,-4) (0,-2) (0,1) (0,3)

Relative min: (-3.193, -25) (2.193, 25)

Relative max: (-0.5, 27.563)

Step-by-step explanation:

The terms can be counted, seperated by the + and - in the equation given.

The highest exponent is your degree.

The number before the highest term is your leading coeff, if there is no number it is 1.

The turning points are where the graph goes from falling to increasing or vice versa.

End behaviour you have to look at what why does when x goes to -inf and inf.

X int are the points at which the graph crosses the x-axis.

The relative min and max are findable if you plug in the graph on desmos or a graphing calculator.
