What is the first four terms in the multiplication or ,geometric , pattern in which the first term is 2 and then each term is mu

kirza4 [7]

Answer:

Sequence will be 2, 14, 98, 686.

Step-by-step explanation:

Since we know in an geometric sequence the terms are in the form are

$T_{n}=a(r)^{n-1}$ in which

a = first term

r = common ratio

n = number of term

Now from this expression we can all terms of the sequence

in which a = 2 and common ratio r = 7

The sequence will be

$2, 2.(7), 2.(7)^{2},2.(7)^{3}$

Or 2, 14, 98, 686

So the answer is 2, 14, 98, 686.

Let r vary directly with s and inversely with t. Which equation represents this equation? Assume that a is a constant.

andrew11 [14]

$\bf \qquad \qquad \textit{combined variation}
\\\\
\begin{array}{llll}
\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}
\end{array}\implies y=\cfrac{kx}{z}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\stackrel{\textit{\underline{r} varies directly with \underline{s} and inversely with \underline{t}}}{r=\cfrac{ks}{t}\qquad \textit{ and since a = k}\qquad r=\cfrac{as}{t}}$

What is the sum of these mixed numbers 4 2/3+ 3 1/9

Mariana [72]

Hello!

First you have to make the denominators the same so the numbers are comparable.

You can multiply the top and bottom number in 2/3 to get 6/9

Now you add

4 6/9 + 3 1/9 = 7 7/9

The answer is 7 7/9

Hope this helps!
