Larry is making a model of the Solar System. What objects will Larry need to put in his model of the Solar System? Name three types of objects. Describe where Larry should place Earth within the Solar System. es ) your answer below:​

(2/3 (x^2+4)^(1/2) (x^2-9)^((-2)/3)-x(x^2-9)^(1/3) (x^2+4)^((-1)/2))/(x^2+4)

The two terms in the numerator are 2/3 (x^2+4)^(1/2) (x^2-9)^((-2)/3)
and -x(x^2-9)^(1/3) (x^2+4)^((-1)/2)

Dividing the first term with the denominator (x^2+4), you get: 2/3 (x^2+4)^(-(1)/2) (x^2-9)^((-2)/3)

Dividing the second term with the denominator, you get: -x(x^2-9)^(1/3) (x^2+4)^((-3)/2)

So, combining the results(that is adding them), the answer is:

2/3 (x^2+4)^(-(1)/2) (x^2-9)^((-2)/3) -x(x^2-9)^(1/3) (x^2+4)^((-3)/2)

Explanation:

change in K.E = change in P.E

1/2 mv^2 = mgh

v^2 = 2gh

v^2 = 2x 32x82

v^2 = 5248

taking square root

v= 72 ft
