SAS Postulate

we know that the triangles (as a whole) as vertical angles meaning they are congruent. We also know FD and BD are congruent to themselves by the reflexive property. And the last side is already congruent (it’s given) :))

navik [9.2K]

Answer:

93.1

24.83

24.13

2755

12.75

0.151

Step-by-step explanation:

Given :

21.1 + 45.99 + 26.0 = 93.09

15.55 + 21.61 - 12.333 = 24.827

14 + 0.8 + 9.33 = 24.13

14.5 * 190 = 2755

5.1 * 2.5 = 12.75

0.15 ÷ 0.991 = 0.151

I’m having trouble with this problem. Please help
iVinArrow [24]

The software rendering this question really butchered it... I think it's saying the displacement vector for the particle is

\vec r(t) = \sin(t) \, \vec\imath + 4t^3 \, \vec\jmath + 5t \, \vec k

Differentiate twice with respect to time t to get the velocity and acceleration vectors, respectively:

\dfrac{d\vec r}{dt} = \vec v(t) = \cos(t) \,\vec\imath + 12t^2 \,\vec\jmath + 5 \,\vec k

\dfrac{d^2\vec r}{dt^2} = \dfrac{d\vec v}{dt} = \vec a(t) = -\sin(t) \,\vec\imath + 24t \,\vec\jmath

Then at t=3, the acceleration of the particle is

\vec a(3) = -\sin(3)\,\vec\imath + 72\,\vec\jmath

which most closely resembles the first choice.
