Mathematics

Aleksandr [31]3 years ago
6 0

Answer:

g(-3)= -45

Step-by-step explanation:

G(n)=n^{3}-2n^{2} \\

Now you have to replace n for -3 because you have to find g(-3).

g(-3) = (-3)^{3}-2(-3)^{2} \\= -27-18 \\=-45

Use the formula to evaluate the series 1/4 + 1/9 + 1/27 + 1/81.
Dmitriy789 [7]
Is the first term supposed to be 1/4, or did you actually mean 1/3?

I'll assume the latter. Write

S=\dfrac13+\dfrac19+\dfrac1{27}+\dfrac1{81}
S=\dfrac13+\dfrac1{3^2}+\dfrac1{3^3}+\dfrac1{3^4}
\dfrac13S=\dfrac1{3^2}+\dfrac1{3^3}+\dfrac1{3^4}+\dfrac1{3^5}
\implies S-\dfrac13S=\dfrac13-\dfrac1{3^5}
\dfrac23S=\dfrac13\left(1-\dfrac1{3^4}\right)
S=\dfrac12\left(1-\dfrac1{81}\right)
S=\dfrac{40}{81}

Leviafan [203]

Answer:

$324.00

Step-by-step explanation:

Increase the number by 8% of its value.

Percentage increase = 8% × 300

New value =

300 + Percentage increase =

300 + (8% × 300) =

300 + 8% × 300 =

(1 + 8%) × 300 =

(100% + 8%) × 300 =

108% × 300 =

108 ÷ 100 × 300 =

108 × 300 ÷ 100 =

32,400 ÷ 100 =

324
