Answer:
<em>15.4 </em>
Step-by-step explanation:
= tan51.3° ⇒ u = 4tan51.3° ≈ 5
= cos51.3° ⇒ v =
≈ 6.4
<em>P </em>≈ 4 + 5 + 6.4 = <em>15.4</em>
-1/2 + 2 = 1.5
because if u add 2 to a minus half it goes 0 and then 1.5 (positive half)
The information given requires you to rework the formula as :
distance÷time=rate
so then plug in values to get
5÷2=rate
and the answer will be 2.5 as your rate
Your answer is 158 hope this helps.
