Consider a sequence generated by the formula f(n) = 6n − 4 starting with n = 1. Generate the terms f(1),
Ierofanga [76]

Answer:

See explanation below

Step-by-step explanation:

To get all the terms in this sequence, all you need to do is to put the values of n, starting from 1 to 5 in the formula.

The part where n is, you just put the value given.

To get for example f(5), you only need to put n = 5 in the formula, do the math and then get the result.

Here are the values of f1, f2, f3, f4 and f5. Again, we will use the following values for n: 1,2,3,4,5

f(1) = 6(1) - 4 = 6 - 4 = 2

f(2) = 6(2) - 4 = 12 - 4 = 8

f(3) = 6(3) - 4 = 18 - 4 = 14

f(4) = 6(4) - 4 = 24 - 4 = 20

f(5) = 6(5) - 4 = 30 - 4 = 26

What is the answer to this question?
geniusboy [140]

Answer:

A-75 and B-25

Step-by-step explanation:

Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section.  Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.

54 books make up 25% of the books in the library. How many books are there in the library.
Scrat [10]

25% is 1/4.

This means that 1/4 of the books in the library is 54, so just multiply 54 by 4, which gives you 100%, or all of the books. 54 times 4 is equal to 216, so there are 216 books in the library.

Simplify the square root of four over the cubed root of four.
Vikki [24]

\bf ~\hspace{7em}\textit{rational exponents} \\\\ a^{\frac{ n}{ m}} \implies \sqrt[ m]{a^ n} ~\hspace{10em} a^{-\frac{ n}{ m}} \implies \cfrac{1}{a^{\frac{ n}{ m}}} \implies \cfrac{1}{\sqrt[ m]{a^ n}} \\\\\\ ~\hspace{7em}\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} ~\hspace{4.5em} a^n\implies \cfrac{1}{a^{-n}} ~\hspace{4.5em} \cfrac{a^n}{a^m}\implies a^na^{-m}\implies a^{n-m} \\\\[-0.35em] \rule{34em}{0.25pt}

\bf \cfrac{\sqrt{4}}{\sqrt[3]{4}}\implies \cfrac{\sqrt[2]{4}}{\sqrt[3]{4}}\implies \cfrac{4^{\frac{1}{2}}}{4^{\frac{1}{3}}}\implies 4^{\frac{1}{2}}\cdot 4^{-\frac{1}{3}}\implies 4^{\frac{1}{2}-\frac{1}{3}}\implies 4^{\frac{3-2}{6}} \\\\\\ 4^{\frac{1}{6}}\implies (2^2)^{\frac{1}{6}}\implies 2^{2\cdot \frac{1}{6}}\implies 2\frac{1}{3}\implies \sqrt[3]{2}
