Your answer is D because rhombus because you can look at examples that are rhombus like the trapezoid and the diamond
<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>
Answer:
56 people
Step-by-step explanation:
49 times 8= 392
392 divided 7= 56
The decimal form is x=1.2 and the mixed number is x= 1 1/5
Definition of an equilateral triangle: A triangle with the exact same sides and angles, which is 60°
<em>5 more than twice a number:</em>
Let the number be x:
2x + 5
<em>Since it is an equilateral triangle, multiply that by 3:</em>
3(2x +5) = 6x + 15
The perimeter is (6x + 15) inches.
