Answer:
x=-4,4,-3,3
Step-by-step explanation:
<u>Factor</u><u> </u><u>by</u><u> </u><u>the</u><u> </u><u>difference</u><u> </u><u>of</u><u> </u><u>two</u><u> </u><u>squares</u>
Therefore, our answer is x = -4,4,-3,3
The length of the side = <span>The length of the arc intercepted by the central
<span>angle
</span></span>∴ length = Θ r
where Θ = <span>central<span> angle in radians
and r = radius
∴ </span></span><span>Θ = 70° = 70 * π /180
</span><span>r = 13 in.
∴ </span>length = <span>(70 * π /180) * 13 ≈ 15.88 in.

Solve using differentials
In differentiation:
Express 126 as 125 + 1;
i.e.
So, we have:
To calculate f(125), we have:
So:
Also:
Rewrite as:
Differentiate
Using law of indices, we have:
So:
So, we have:
