Find the focus and the directrix of the parabola with the equation y = 1∕4(x – 6)2+ 5 Question 20 options: A) Focus = (–5,6), directrix is y = –4 B) Focus = (5,–6), directrix is y = –7 C) Focus = (6,6), directrix is y = 4 D) Focus = (6,–6), directrix is y = –4

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

you divide them and then you get the answer i took this class this year
