Answer:
Cos x = 1 - 
+ 
- 
+ ...
Step-by-step explanation:
We use Taylor series expansion to answer this question.
We have to find the expansion of cos x at x = 0
f(x) = cos x, f'(x) = -sin x, f''(x) = -cos x, f'''(x) = sin x, f''''(x) = cos x
Now we evaluate them at x = 0.
f(0) = 1, f'(0) = 0, f''(0) = -1, f'''(0) = 0, f''''(0) = 1
Now, by Taylor series expansion we have
f(x) = f(a) + f'(a)(x-a) + 
+ 
+ 
+ ...
Putting a = 0 and all the values from above in the expansion, we get,
Cos x = 1 - + - + ...
It’s probably B because the domain is all real numbers
<span>1.7a+0.3a=4/5
2a = 4/5
a = 4/5 * 1/2
a = 4/10
a = 2/5</span>

Answer:
The number of pet dogs are 11.61% less than the number of pet cats.
Step-by-step explanation:
Number of pet dogs in the United states = 76.9 million
Number of pet cats in the United states = 87 million
Difference between the number of cats and dogs :
Percentage of number of pet dogs less than pet cats:
The number of pet dogs are 11.61% less than the number of pet cats.
