Car A began a journey from a point at 9 am, traveling at 30 mph. At 10 am car B started traveling from the same point at 40 mph
Natasha2012 [34]
Let after t hours the distances D1<span> traveled by car A</span>

=> D1<span> = 30 t</span>

Car B starts at 10 am and will, therefore, have spent one hour less than car A when it passes it.

After (t - 1) hours, distance D2<span> traveled by car B </span>

=> D2<span> = 40 (t - 1)</span>

When car B passes car A, they are at the same distance from the starting point and therefore<span> D1 = D2 </span>

=> 30 t = 40 (t - 1)

Solve the equation for t,

=> 30 t = 40t - 40

=> 10 t = 40

=> t = 4

=><span> Car B passes car A at = 9 + 4 = 13 pm.</span>

Given sin(-0)=-1/6 and tan0=-√35/35
elena55 [62]

Answer:

<u>Option a. √35/6</u>

Step-by-step explanation:

Given  sin θ = -1/6  and tan θ = -√35/35

We should know that :

tan θ = (sin θ)/(cos θ)

∴ Cos θ = (sin θ)/(tan θ)

∴ Cos θ = (-1/6)/(-√35/35) = (-1/6) * (-35/√35)

             =  35/(6√35) = (√35 * √35)/(6√35) = √35/6

<u>The answer is option a. √35/6</u>
