(2,3) so x=2, y=3 and h=(2^2+3^2)^(1/2)=√13

sina=3/√13, cosa=2/√13, tana=3/2 Afterwards multiply sina and cosa by √13/√13 and get sina=(3√13)/13 and cosa=(2√13)/13

Answer:

8 units

Step-by-step explanation:

Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...

A = (1/2)(b1 +b2)h

to find the area.

Here, b1=3, b2=1, h=4, so the area is ...

A = (1/2)(3 +1)(4) = 8

The displacement is 8 units in the time from t=1 to t=4.
