Answer:

$\large\boxed{(x^3)(-x^3y)^2=x^9y^2}$

Step-by-step explanation:

$(x^3)(-x^3y)^2\qquad\text{use}\ (ab)^n=a^nb^n\\\\=(x^3)(-x^3)^2(y^2)\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=(x^3)(x^6)(y^2)\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=x^{3+6}y^2\\\\=x^9y^2$

Jason jumped off of a cliff into the ocean in Acapulco while vacationing with some friends. His height above ocean measured in f

lbvjy [14]

Answer:

480 feet.

Step-by-step explanation:

We are told that the function $h(t)=-16t^2+16t+480$ models Jason's height above ocean measured in feet as a function of time and t is the time in seconds from jumping off.

To find the height of cliff we need to substitute t=0 in our given function as at t=0 we will get Jason's height above ocean which is same as the height of the cliff.

Upon substituting t=0 in our function we will get,

$h(0)=-16(0)^2+16*0+480$
