Answer:
Step-by-step explanation:
If the question is to factorize
![x^4-17x^2+16\\\\x^4-x^2-16x^2+16\\\\=x^2(x^2-1)-16(x^2-1)\\\\=(x^2-1)(x^2-16)\\\\=(x+1)(x-1)(x-4)(x+4)\\](https://tex.z-dn.net/?f=x%5E4-17x%5E2%2B16%5C%5C%5C%5Cx%5E4-x%5E2-16x%5E2%2B16%5C%5C%5C%5C%3Dx%5E2%28x%5E2-1%29-16%28x%5E2-1%29%5C%5C%5C%5C%3D%28x%5E2-1%29%28x%5E2-16%29%5C%5C%5C%5C%3D%28x%2B1%29%28x-1%29%28x-4%29%28x%2B4%29%5C%5C)
LKJ= 360
L and J are congruent
360-64-36= 260
X=260-80
260-80 =180
X=180
<span>I am assuming that this is a parametric curve.
We see that the curve intersects the x-axis when:
t - t^2 = 0 ==> t = 0 and t = 1.
Then, since x = 1 + e^t is an increasing function, the curve is being traced exactly once on the interval (0, 1).
Using the fact that the area under the curve given by the parametric equations x = f(t) and y = g(t) on (a, b) is:
A = ∫ f'(t)g(t) dt (from t=a to b),
and that f(t) = 1 + e^t ==> f'(t) = e^t, the area under the curve is:
A = ∫ e^t(t - t^2) dt (from t=0 to 1)
= e^t(-t^2 + 3t - 3) (evaluated from t=0 to 1), by integrating by parts
= e(-1 + 3 - 3) - (0 + 0 - 3)
= 3 - e. </span>
