At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f

IgorLugansk [536]

Use the equation of motion under gravity:-

s = 16t^2 where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 = 128.94 s

t = sqrt 128.94 = 11. 4 seconds to the nearest tenth of a second

Which expression is equivalent to 4^ 5x4^ -7÷4 ^-2?

Andre45 [30]

$\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^{-n} \qquad \qquad a^n\implies \cfrac{1}{a^{-n}}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ 4^5\cdot 4^{-7}\div 4^{-2}\implies \cfrac{4^5\cdot 4^{-7}}{4^{-2}}\implies \cfrac{4^{5-7}}{4^{-2}}\implies \cfrac{4^{-2}}{4^{-2}}\implies 4^{-2}\cdot 4^2 \\\\\\ 4^{-2+2}\implies \boxed{4^0}\implies 1$
