Use FOIL: <em>(a + b)(c + d) = ac + ad + bc + bd</em>

(2s - 2)(4s + 3)

= (2s)(4s) + (2s)(3) + (-2)(4s) + (-2)(3)

= 8s² + 6s - 8s - 6

Find a unit vector in the direction of the vector left bracket Start 3 By 1 Matrix 1st Row 1st Column negative 8 2nd Row 1st Col

MrRissso [65]

Answer:

$\left[\begin{array}{c}-\frac{8}{\sqrt{117} } \\\frac{7}{\sqrt{117} }\\\frac{2}{\sqrt{117} }\end{array}\right]$

Step-by-step explanation:

We are required to find a unit vector in the direction of:

$\left[\begin{array}{c}-8\\7\\2\end{array}\right]$

Unit Vector, $\hat{a}=\dfrac{\overrightarrow{a}}{|\overrightarrow{a}|}$

The Modulus of $\overrightarrow{a}$ = $\sqrt{(-8)^2+7^2+(-2)^2}=\sqrt{117}$

Therefore, the unit vector of the matrix is given as:

$\left[\begin{array}{c}-\frac{8}{\sqrt{117} } \\\frac{7}{\sqrt{117} }\\\frac{2}{\sqrt{117} }\end{array}\right]$

Find the value of X. The diagram is not to scale. Lines F and G are parallel.

sergejj [24]

Step-by-step explanation:

2 × (First Angle + Second Angle) = 360°

5x + 9x + 26 = 360°/2

14x + 26 = 180°

14x = 180 - 26

14x = 154

x = 154/14

x = 11°

The answer is B.
