30 points!!<br> What is the sum of the first six terms of the series?<br> 48 - 12 + 3 - 0.75 +...
Lunna [17]

Answer:

The sum of the first six terms is 38.39

Step-by-step explanation:

This is a geometric sequence since the common difference between each term is -\frac{1}{4}

Thus, r=-\frac{1}{4}

To find the sum of first six terms, we need to find the fifth and sixth term of the sequence.

To find the fifth term:

The general form of geometric sequence is a_{n}=a_{1} \cdot r^{n-1}

To find the fifth term, substitute n=5 in a_{n}=a_{1} \cdot r^{n-1}

\begin{aligned}a_{5} &=(48) \cdot\left(-\frac{1}{4}\right)^{5-1} \\&=(48) \cdot\left(-\frac{1}{4}\right)^{4} \\&=(48)\left(\frac{1}{256}\right) \\a_{5} &=0.1875\end{aligned}

To find the sixth term, substitute n=6 in a_{n}=a_{1} \cdot r^{n-1}

\begin{aligned}a_{6} &=(48) \cdot\left(-\frac{1}{4}\right)^{6-1} \\&=(48) \cdot\left(-\frac{1}{4}\right)^{5} \\&=(48)\left(-\frac{1}{1024}\right) \\a_{5} &=-0.046875\end{aligned}

To find the sum of the first six terms:

The general formula to find Sn for |r| is S_{n}=\frac{a\left(1-r^{n}\right)}{1-r}

\begin{aligned}S_{6} &=\frac{48\left(1-\left(-\frac{1}{4}\right)^{6}\right)}{1-\left(-\frac{1}{4}\right)} \\&=\frac{48\left(1-\frac{1}{4096}\right)}{1+\frac{1}{4096}} \\&=\frac{48(0.95)}{5} \\&=\frac{48(0.9998)}{5} \\&=\frac{48(0.9998)}{5} \\&=\frac{47.9904}{5} \\&=38.39\end{aligned}

Thus, the sum of first six terms is 38.39

Slope = 2/5 ; Passes through (-4, -7) ; Point-slope form

point-slope form : y-y₁=m(x-x₁)

Simply plug everything in :)

Remember !! m=slope

y - (-7) = 2/3(x - (-4))

Simplify.

y + 7 = 2/3(x + 4)

*Some teachers want this simplified more so here's the simplest answer : 

y + 7 = 2/3x + 8/3 *

~Hope I helped!~

Solve this system of equations by using the substitution method. y=2x-5 6x+7=y
gogolik [260]

Answer:

x =  - 3 \: and \: y =  - 11

Step-by-step explanation:

L

since \: y = 2x - 5(equation \: 1) \:  \\

substitute \: for \: y \: in  \: equation \: 2 \:  (6x + 7 = y)

6x + 7 = y \\ 6x + 7 = 2x - 5 \\ collect \: like \: terms \\ 6x - 2x =  - 5 - 7 \\ 4x =  - 12 \\ x =  \frac{ - 12}{4}  \\ x =  - 3

substitute \: for \: x  in \: equation \: 1

y = 2x - 5 \\ y = 2( - 3) - 5 \\ y =  - 6 - 5 \\ y =  - 11
