The standard equation of parabola:
(y-k)²=4p(x-h), with:
a) vertex = (h,k)
b) focus = (h+p, k)
c) directrix = (x=h-p)
Since this parabola has a vertex at (0,0) that means h=k=0
Hence the equation becomes: y²=4px, let's calculate p:
focus is given (-9,0) Remember h+p = -9 & since h=0, then p= -9
===> y²= - 36x
The fraction would be 35/100, in simplest form that is 7/20.
The answer to the solution is x=43+√249/2
I hope this helps.
Answer: " 0.95 " .
___________________________________
Step-by-step explanation:
___________________________________
;
= 95 ÷ 100 ;
Note: to divide a number by "100" ; you take the decimal place of the original number, and move the decimal space two spaces backward.
= 95. ÷ 100 = .95 ; → write as: " 0.95 " .
____________________________________
<u> Other method</u>:
19/20 = 19 ÷ 20 ; Use calculator; to get the exact number:
→ " 0.95 " ;
→ which is already rounded to the nearest hundredths place.
