What is the equation of a horizontal ellipse with a center at point (-2,4), a major axis that is 8 units long, and a minor axis that is 4 units long? 1.)(x+2)2/8+(y-4)2/4=1..2.)(x+2)2/4 +(y-4)2/16=1..3)..(x+2)2/16+(y-4)2/ 4=1..4)..(x-2)2/16+(y+4)2/4=1

step-by-step explanation:

hi! i think the answer is 1/2 : )

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
