Answer:
70,000
Step-by-step explanation:
66,681 is closest to 70,000 rather than 60,000.
Answer:
496+1404+2695+489=5084
Step-by-step explanation:
5084 is closer to 5,000 than it is to 4000. 5084 is only 84 more than 5000, but its 1084 away from 4000
Answer:
Cos A = 3/5
Step-by-step explanation:
Points to remember
<u>Trigonometric ratios
</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see a right angled triangle, ABC
AC = 9, CB = 12 and AB = 15
<u>To find the value of Cos A</u>
Cos A = Adjacent side/Hypotenuse
= AC/AB
= 9/15 = 3/5
Therefore the value of Cos A = 3/5
Answer:
0.44237 units
Step-by-step explanation:
Given


Required
The distance traveled in this interval
We have:

The distance is calculated as:

So, we have:

Let:

Differentiate

So:

So, we have:


Rewrite as:


Integrate:

Substitute 

Split
