Answer:

(0,-1) and (1,3) are the coordinates you draw he line through

Step-by-step explanation:

plot a point at -1 on the y axis and then turn the 4 into an improper fraction like 4/1 then you take the 4 on top of the fraction go up 4 units and over to the right 1 and those are your two points just draw a line in between 'em

Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho

gulaghasi [49]

$1813\times10^9$ cells were not burnt when Jennie escaped from the fire.

<u>Solution:</u>

Given:

2% of skin cells were burnt i.e, $3.7\times10^{10}$ of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write $3.7\times10^{10} \text{ as } 37\times10^{9}$

Therefore, by equating the values we get,

2% of the cell is $37\times10^9$

1% of the cell is $\frac{37\times10^9}{3}=18.5\times10^9$

As, 1% of the cell is $18.5\times10^9$

98% of the cell will be $98\times18.5\times10^9=1813\times10^9$

$\therefore \text{ skin cells that are not burnt is } 1813\times10^9$

How do u do question 6. Pls help fast

photoshop1234 [79]

$y= \frac{a}{x-h} +k
\\x=4 \ vertical\ asymptote
\\ Vertical\ asymptote \ can\ be\ found \ from
\\ \\x - h = 0,\ x=h,
\\ \\ so \ h = 4
\\ \\ y= \frac{a}{x-4} + k= \frac{a+kx-4k}{x-4} 
\\Vertical\ asymptote \ can\ be\ found\ as 
\\ \\ \frac{kx}{x} = k.
\\ We\ know\ that\ vertical\ asymptote\ is\ 2,\ so\ k=2.
\\ \\ y= \frac{a}{x-4} + 2
\\ \\ We \ need\ to\ find\ a.\ We\ have\ point\ (5,4),\ that\ belongs\ to\ \\this\ function.\ So,
\\ \\ y= \frac{a}{x-4} + 2
\\ \\4= \frac{a}{5-4} + 2



$

$4= \frac{a}{5-4} + 2
\\ \\ 2= \frac{a}{1} 
\\ \\ a=2
\\ \\ So,\ hyperbola\ has\ formula
\\ \\ y= \frac{2}{x-4} +2$
