Add or Subract.Write your answer in scientific notation.6.4+(10×10×10)+1.4×(10×10×10×10)+7.5×(10×10×10)

Sergeeva-Olga [200]

Answer:

$1.53\times10^4$

Step-by-step explanation:

The given expression is:

$6.4\times(10*10*10)+1.4\times(10*10*10)+7.5\times(10*10*10)$

We apply the distributive property to get:

$(6.4+1.4+7.5)\times(10*10*10)$

We add to get:

$(6.4+1.4+7.5)\times(10*10*10)$

$15.3\times10^3$

In scientific notation, we have

$1.53\times10^4$

What is limit of (startstartfraction negative sine (startfraction pi x over 3 endfraction) overover 3 endendfraction) as x appro

Nutka1998 [239]

I'm guessing your limit is

$\displaystyle \lim_{x\to5} \frac{-\sin\left(\frac{\pi x}3\right)}3$

The limand is continuous at x = 5, so we can evaluate the limit directly by substituting x = 5:

$\displaystyle \lim_{x\to5} \frac{-\sin\left(\frac{\pi x}3\right)}3 = -\frac13 \sin\left(\frac{5\pi}3\right) = -\frac13 \times \left(-\frac{\sqrt3}2\right) = \boxed{\frac1{2\sqrt3}} = \boxed{\frac{\sqrt3}6}$
