How to simplify fractions ti its lowest terms

What is the 101st term for the sequence 13, 9, 5, 1... ?

NeX [460]

Step-by-step explanation:

a=13
d=13-9=4

${:}\longrightarrow$ $\sf S_n={\dfrac {n}{2}}\left [2a-(a-1)d\right]$

${:}\longrightarrow$ $\sf S_101={\dfrac {101}{2}}\left [26 (12)4\right]$

${:}\longrightarrow$ $\sf 50.5×1248$

${:}\longrightarrow$ $\sf S_101=63504$

${:}\longrightarrow$ $\sf a_n=a+(n-1)d$

${:}\longrightarrow$ $\sf a_101=13+(101-1)-4$

${:}\longrightarrow$ $\sf a_101=13+100(-4)$

${:}\longrightarrow$ $\sf 13-400$

${:}\longrightarrow$ $\sf a_101=-387$

PLEASE HELP !! suppose that F(x)=x^2 and G(x)=3x^2+8.which statement best compares the graph of G(x) with the graph of F(x)

Leno4ka [110]

Answer:

The graph of g(x) is the graph of f(x) stretched by 3 and shifted 8 units up

Step-by-step explanation:

Given

$f(x)=x^2$

$g(x) =3x^2 + 8$

Required

Compare g(x) and f(x)

We have:

$g(x) =3x^2 + 8$

Rewrite as:

$g(x) =3[x^2] + 8$

Substitute: $f(x)=x^2$

$g(x) =3f(x) + 8$

This means that:

3f(x)

f(x) is stretched vertically by a factor of 3

+8

Then shifted upwards by 8 units to give g(x)
