Find the sum of the geometric series. 20-10+5-5/2+ a. 3718/13 b. 40/3 c. 3003/7 d. 715 select the best answer from the choices provided a) a b) b c) c d) d

40/3  option B

Step-by-step explanation:

20-10+5-5/2+ ...

We need to find the sum of infinite geometric series

a is the first term (20)

r is the common ratio

To find common ratio we divide second term by first term

r=

now we plug in the values

sum = 40/3

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
