Use geometric series to find the fraction of 0.8967898989
Sliva [168]

I'm guessing the repeating part is 89 at the end, so that

x=0.8967\overline89\implies10^4x=8967.\overline{89}

Then

10^4x=8967+\displaystyle89\sum_{i=1}^\infty\frac1{100^i}

10^4x=8967+89\left(\dfrac1{1-\frac1{100}}-1\right)

10^4x=8967+\dfrac{89}{99}

x=\dfrac{8967}{10^4}+\dfrac{89}{99\cdot10^4}

x=\dfrac{443911}{495000}

###

An arguably quicker way without using geometric series:

10^4x=8967.\overline{89}

10^6x=896789.\overline{89}

10^6x-10^4x=887822

x=\dfrac{887822}{10^6-10^4}=\dfrac{443911}{495000}

A line segment contains the points (4,8) and(2,-4). what is the slope of a line segment perpendicular to the given lin segment?
Mice21 [21]

Answer:

-1/6

Step-by-step explanation:

Slope=change in y/change in x

Y-values: 8 and -4

X-values: 4 and 2

Change is the difference in position (subtract)

8- (-4)/(4-2)=12/2=6 = first slope

Perpendicular lines have opposite reciprocal slope
