Step-by-step explanation:
I don't know
Recall the Maclaurin expansion for cos(x), valid for all real x :

Then replacing x with √5 x (I'm assuming you mean √5 times x, and not √(5x)) gives

The first 3 terms of the series are

and the general n-th term is as shown in the series.
In case you did mean cos(√(5x)), we would instead end up with

which amounts to replacing the x with √x in the expansion of cos(√5 x) :

Answer:
10 ( b+10)
Step-by-step explanation:
10 b + 100
Factor out a 10
10 * b + 10 * 10
10 ( b+ 10)
hope it helps !!!!
Answer:
D) J
B) point Q
Step-by-step explanation:
we know that the ginipigs are only given 80 in total. that means 80 is 100%
40÷80*100=50%
20÷80*100=25%
10÷80*100= 12.5%
10÷80*100= 12.5%
all this together is 100%
meaning the best answer is
Q is the only place that = -1/2
