Write an equation for a function that has vertical asymptotes at x=3 & x=-10

Mathematics

stepan [7]3 years ago

Answer:

\frac{5}{ {x}^{2}   + 7x - 30}

Step-by-step explanation:

We can write a rational function.

We need to make sure our denominator both have zeroes at 3 and 10.

Set an equation equal to zero to find the function

0 - x = 3

0 - x =  - 10

0 - ( - 3) =  = 3

0 - 10 = 10

So we would represent that's as

x - 3

and

x + 10

Multiply the two binomial together.

(x - 3)(x + 10) =  {x}^{2}  + 7x  - 30

Let our numbetator be any interger.

Use any equation as long as the quadratic is the denominator and the interger is the numerator.

\frac{5}{ {x}^{2} + 7x - 30 }

36 boys complete a school task in 4 hours. How many boys would be required to complete the same task in 2¼ hours?​
vova2212 [387]

Answer:

20

Step-by-step explanation:

If 36 boys can conplete a task in 4 hours, then 19.35 boys could do it in 2 and a fourth hours.

You can set up an equation

A fourth of an hour is 15 minutes, so,

36 is to 4 as x is to 2.15, or,

36=4 as X=2.15

Multiply 2.15 by 36 (77.4)

77.4 divided by 4= 19.35.

Of course, you cannot have 19.35 boys, so there must be 20.

Hope this helps!
