Step-by-step explanation:

The binomial theorem states that for some a,b∈R and some k ∈Z+ ,
(a+b)k=∑n=0k(kn)ak−nbn.
The binomial series allows us to use the binomial theorem for instances when k is not a positive integer. The binomial series applies to a given function f(x)=(1+x)k for any k∈R with the condition that |x|<1 . It is stated as follows:
(1+x)k=∑n=0∞(kn)xn .
Note that the binomial theorem produces a finite sum and the binomial series produces an infinite sum.
5x- 10 = 20
5x -10 +10 = 20 +10
5x = 30
5x/5 =30/5
x = 6
The pythagorean theorem works for all right triangles. Just make sure it IS a right triangle.
Answer:
25 Seconds.
Step-by-step explanation:
You need to know how many seconds it takes to read the bottom of the lake.
If, each second, the anchor is falling 0.7 feet, then you need to know how many times it falls 0.7 feet.
This is done by dividing 17.5 by 0.7, which is 25 seconds.
