$\bf \cfrac{1}{3}\sqrt[3]{81}\implies \cfrac{1}{3}\sqrt[3]{3^4}\implies \cfrac{1}{3}\sqrt[3]{3^{3+1}}\implies \cfrac{1}{3}\sqrt[3]{3^3\cdot 3^1}\implies \cfrac{1}{3}\cdot 3\sqrt[3]{3^1}
\\\\\\
\sqrt[3]{3}$

Let m=x²-5. which equation is equivalent to (x²-5)²-3x²+15=-2 in term of m?

SpyIntel [72]

The answer would be m^2+3m+2=0 because the first “part” of the equation (x^2-5) is equal to m; in the equation it’s squared so it can be replaced by m^2. next, 3m is the same as 3(x^2+5) which is what you have when you see 3x^2+15. finally, you have to bring the -2 over from the other side so you have positive 2. hope this helps!

Morgarella [4.7K]

Answer:

The domain that makes sense for this function is all values greater than or equal to 0.

Step-by-step explanation:

A ball is thrown into the air from a height of 4 feet at time t = 0. It is modeled by the function:

$h(t)=-16t^2+64t+4$
