Write the explicit formula for the geometric sequence.
My name is Ann [436]

Answer:

D

Step-by-step explanation:

the n th term ( explicit formula ) of a geometric sequence is

• a_{n} = a_{1}(r)^{n-1}

where r is the common ratio and a_{1} the first term

here r = \frac{8}{16} = \frac{16}{32} = \frac{1}{2} and a_{1} = 64, hence

a_{n} = 64(0.5)^{n-1} → D

Subtract 43 from 20 raised to the 7th power; then multiply by 3.
viktelen [127]

Hi there! :)

<u>Answer:</u>

Subtract 43 from 20 raised to the 7th power; then multiply by 3. The answer is: <u>3,839,999,871</u>

Step-by-step explanation:

"Subtract" means to take away a number from another.

" 20 raised to the 7th power" is the same thing as 20 exponent 7: 20^{7}


SO, you want to take away 43 from 20^{7} and then multiply the answer by 3:

(20^{7} - 43) × 3

20^{7} = 1,280,000,000

(1,280,000,000 - 43) × 3

1,280,000,000 - 43 = 1,279,999,957

1,279,999,957 × 3

1,279,999,957 × 3 = <u>3,839,999,871</u>


There you go! I really hope this helped, if there's anything just let me know! :)

Consider the equations 15x + 9y = 45 and 9x + 8y = 12. Solve the system of equations using elimination. Give your solution to th
True [87]

Answer:

(-5.77, 6.46)

Step-by-step explanation:

15x + 9y = 45 ----------- i

9x + 8y = 12----------------ii

Multiply equation i by 9 the coefficient of x in equ ii

And equation ii by 15 the coefficient of x in equ I

9 x 15x + 9y = 45 ----------- i

15 x 9x + 8y = 12----------------ii

135x+81y = 405

135x+120y= 180

Subtract equation ii from I

135x-135x+81y-(+120y)= 405-180

-39y=225

y = 225/-39 = -5.77

Insert the value of y in equ i

15x + 9y = 45

15x+9(-5.77) = 45

15x-51.92=45

15x = 45+51.92

15x= 96.92

x = 96.92/15= 6.46

(x,y) = (-5.77, 6.46)

x = 6.92/15
