log_a(b)=clog_a(b)=c translates to

a^c=ba^c=b
let's say it equals y

log_2(25)=ylog_2(25)=y
trsnaltes to
2^y=252^y=25
doesn't help us
we can also translate it to
log_2(5^2)log_2(5^2) or 2log_2(5)log_2(5^2)

Consider the series 4 + 12 + 36 ... Find the sum of the first 9 terms.​
jeyben [28]

Answer:

39364

Step-by-step explanation:

You can simplify the equation to make 4(1+3+9...) The nth term is therefore 3^{n-1} so u can substitute that into the equation so 4(3^{n-1}+ 3^{n}  + 3^{n+1}..). This would simplify to 4(3^0 +3+3^2+3^3+3^4+3^5+3^6+3^7+3^8). By simplifying this, you can make it so 4(2^2+6^2+18^2+42^2+81^2) = 4(4+36+324+2916+6561) =39364

Determine the standard form of the equation of the line that passes through (-2, 0) and (-8, 5).
Vladimir79 [104]

Answer:

5x + 6y = -10

Step-by-step explanation:

(-2, 0) and (-8, 5)

m = (y₂ - y₁) /  (x₂ - x₁)

m = (5 - 0) / (-8 -(-2)

m = 5 / (-8+2)

m = -5/6

y = mx + b

(-8, 5)

5 = -5/6(-8) + b

5 = 40/6 + b

b = 5 - 40/6

b = -5/3

y = mx + b

y = -5/6x - 5/3           *6

6y = -5x -5(2)

6y = -5x - 10

5x + 6y = -10
