Answer:

A: a(t)

B: v(t)

C: s(t)

Step-by-step explanation:

One graph is position, s(t).

Another is velocity, v(t) = ds/dt (slope of the tangent line of the position curve).

The third is acceleration, a(t) = dv/dt (slope of the tangent line of the velocity curve).

If graph A is s(t), then velocity v(t) would always be positive.  No graph fits, so A is not s(t).

If graph B is s(t), then velocity v(t) would start negative then become positive, like graph A does.  If graph A is v(t), then acceleration a(t) would always be positive.  No graph fits, so A is not v(t), which means B is not s(t).

If graph C is s(t), then velocity v(t) would always be negative, like graph B.  If graph B is v(t), then acceleration a(t) starts negative then becomes positive, like graph A does.

Therefore:

A: a(t)

B: v(t)

C: s(t)

Smallest side XYZ/ Smallest side ABC = Longest side XYZ/ Longest side ABC
Let longest side XYZ be x
280/112 = x/144
x = (280/112)×144
x = 360
Option D will be your answer

Hope it helped!

Congruent triangles are all the same. Given that the faces of a triangular pyramid are congruent then all its faces are the same. It is also good to note that this pyramid has 4 faces. Given that the surface area of the pyramid is 372m^2, the area of one face will be:
area=(total area)/(number of faces)
=372/4
=93 m^2
