9x^2+4y^2+54x+8y-59=0 an ellipse in that needs to be in standard form explain how to do

D

edge

Step-by-step explanation:

The standard form of an ellipse is

Let's try to complete some squares: if we focus on the part involing x, we have

Similarly, for the part involving y, we have

So, the equation becomes

Divide both sides by 144 to get

which is the standard form

heyyy

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
