R - 18 = 50
r = 50 + 18 = 68
Hence Rick is 68 yrs old
20 x 6 = 120 in³ ( chocolate )
V ( pyramid ) = 1/3 B h = 1/3 · 1 · 2 = 2/3 in³
120 : 2/3 = 120 · 3/2 = 180
Answer: The largest number of pyramids she can make is B ) 180
Answer:
sinx =1-\frac{1}{2} (x-\frac{\pi}{2} )^2+\frac{1}{24} (x-\frac{\pi}{2} )^4-\frac{1}{720} (x-\frac{\pi}{2} )^6+\frac{1}{40320} (x-\frac{\pi}{2} )^8+...
Step-by-step explanation:
given that f(x) = sin x
we have to find the Taylor series for that

and so on.
i.e. 2nd, 4th, 6th terms would be 0
and also 1st, 5th, 9th terms would be positive for f value and 3rd, 9th,... would be negative
Using the above we can write Taylor series as


This is valid for all real values of x.
x ∈
