What is the sum of a 6-term geometric series if the first term is 23 and the last term is 1,358,127? 1,395,030 1,461,460 1,527,890?

Last term is 1,527,890.

Step-by-step explanation:

In this question a geometric series has been given  with

first term A = 23

6th term     = 1,358,127

Number of terms n = 6

we have to calculate the sum of this geometric series

we know

r = 9

Now we know the formula to sum a geometric series is

S = 23 ×

S = 23 ×

S = = 23 × 66430

S = 1,527,890

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
