Cos(30) = x/11

cos(30) × 11 = 9.53

sin(30) × 11 = 5.5

perimeter = 11+9.53+5.5 = 26.03

Hope this helps

Step-by-step explanation:

$\begin{pmatrix}4&1\end{pmatrix}\quad \mathrm{and}\quad \begin{pmatrix}2&9\end{pmatrix}$

$\mathrm{Computing\:dot\:product\:of\:two\:vectors}:\quad \left(x_1,\:\:\ldots ,\:\:x_n\right)\cdot \left(y,\:\:\ldots ,\:\:y_n\right)=\sum _{i=1}^nx_iy_i$

Work out the acceleration for the first 3 seconds?

Finger [1]

The acceleration is given by the slope of the line. This line passes through the points (0, 2) and (3, 5), so it has slope

$\dfrac{5-2}{3-0}=1$

which means the acceleration over this 3 second interval is 1 m/s^2.
