Answer:

s= 15 (nearest integer), 14.8 (to nearest 10ths)

Step-by-step explanation:

here you need to apply the cosine rule,

${s}^{2} = {u}^{2} + {t}^{2} - 2ut \cos(s)$

substituting the values,

u= 13, t=5 and angle S as 60 and solving will give you the answer 14.76 (2 dp)

If u= <4,5> and v= <0,-1>, find 2v+5u

GaryK [48]

Answer:

<20,23>

Step-by-step explanation:

u= <4,5> and v= <0,-1>

2v = 2*<0,-1> = <0,-2>

5u = 5* <4,5> = <20,25>

2v+5u = <0,-2> + <20,25>

= <20,23>
