The answer is true i had the same question

is a classic approximation, true for small x.
The next term in the polynomial expansion will be
where k is a positive number. So our estimate 1-x is definitely an underestimate on both sides of x=0.
Since for negative xs the exponential rises exponentially and the line only linearly, the exponential exceeds the line for all negative x. For positive x, the line quickly goes negative while the exponential is always positive.
So, there's no interval for which our approximation is an overestimate.
Answer:
representations are thought in the form utilized by Horner's method. E.g., in the decimal system we have
(1)√2= 1.41421 ... = 1 + 1/10 (4 + 1/10 (1 + 1/10 (4 + 1/10 (2 + 1/10 (1 + 1/10 ( ... )))))),π= 3.14159 ... = 3 + 1/10 (1 + 1/10 (4 + 1/10 (1 + 1/10 (5 + 1/10 (9 + 1/10 ( ... )))))),
But was there a positional system in which π was known? As S. Rabinowitz has realized, there indeed was such a system albeit an unusual one. The starting point was the series

which also can be written as

or, in the Horner form,

Answer:
52
Step-by-step explanation:
The square means that the angle is a right angle, measuring 90 degrees.
90 = 50 + (x - 12)
Subtract 50 from both sides.
40 = x - 12
Add 12 to both sides.
52 = x
