Find the value of x help 10 points

Mathematics
1 answer:
MrRissso [65]3 years ago

<u>Answer:</u>

x = 5.67

<u>Step-by-step explanation:</u>

We are given a right angled triangle with a length of the hypotenuse 8 with the remaining two sides (base and perpendicular) that are equal to each other.

Assuming the two equal legs of this right angled triangle to be x, we can use the Pythagoras Theorem to find the value of x.

(x)^2+(x)^2=(8)^2

2x^2=64

Taking square root at both the sides to get:

\sqrt{2x^2} =\sqrt{64}

1.41x=8\\\\x=5.67

Therefore, x = 5.67.

Can you please explain to me what the end behavior of the function f(x)=-2x^4-x^3+3 looks like?
Artist 52 [7]
The dominant term is -2x⁴. 

As X approaches infinite, y is naturally going to be really large as well.

Remember that a number with an even exponent, regardless of whether it's positive or negative, will be positive.
As x approaches infinite, y will approach -2 * ∞, or -∞. Therefore, the end behavior in the positive direction is y=-∞
As x approaches negative infinite, y will approach -2 *∞ again. This is because         -∞⁴ = ∞. Therefore, the end behavior in the negative direction is also y=-∞

Basically, due to the dominance of the -2x^4 term, the function will look more or less like a downward facing parabola with a y-intercept of 3.
