If f(x)=3x+9,what is f−1(x)?

1 answer:

8 0

F inverse? then :
let's consider 3x + 9 as y.
so :
y = 3x + 9
y - 9 = 3x
x = y/3 - 3
now replace y with x and you get the inverse.
f^-1 (x) = x/3 - 3

Derive the equation of the parabola with a focus at (_5, 5) and a directrix of y = -1.

mars1129 [50]

Answer: Option D is correct.

Step-by-step explanation:

Since we have given that

focus = (-5,5)

and a directrix y= -1

Since, equation of parabola in this case will be

$(x-h)^2=4.a(y-k)$

Now, here

$y=k-a=-1\\\\\text { focus =(h,k+a)}\\\\\text{So,} k+a=5\\\\\text{ by solving these two equation , we get }\\\\a=3\text{ and } k=2$

So equation will be

$(x+5)^2=4\times 3(y-2)\\\\(x+5)^2=12(y-3)\\\\y=\frac{1}{12}(x+5)^2+2$

So, option D is correct .

What is the remainder when 599 is divided by 9?

Schach [20]

$599=540+59=540+54+5=60(9)+6(9)+5$
$\implies\dfrac{599}9=66+\dfrac59$

so the remainder is 5.
