900! is really 900 * 899 * 898 * 897 * 896 * 895 ......... * 3 * 2 * 1.


899 is really 899 * 898 * 897 * 896 * 895 ......... * 3 * 2 * 1.


\bf \cfrac{900!}{899!}\implies \cfrac{900\cdot 899!}{899!}\implies 900\cdot \cfrac{899!}{899!}\implies 900\cdot 1\implies 900

Answer:

x = \dfrac{-\log 7}{\log 7 - \log 2}

Step-by-step explanation:

2^x = 7^{x + 1}

Take the log of both sides.

\log 2^x = \log 7^{x + 1}

Use properties of log.

x \log 2 = (x + 1) \log 7

x \log 2 = x \log 7 + \log 7

x \log 2 - x \log 7 = \log 7

x(\log 2 - \log 7) = \log 7

x = \dfrac{\log 7}{\log 2 - \log 7}

x = \dfrac{\log 7}{-(\log 7 - \log 2)}

x = \dfrac{-\log 7}{\log 7 - \log 2}

Solve for t. f(t)=-16t^2+576​
IgorC [24]

Answer: t^2=-f-576/16

Step-by-step explanation:

Step 1. Switch the equation around:

-16t^2+576=f

Step 2. Subtract 576 from each side:

-16t^2+576-576=f-576

Step 3. Now simplify:

-16t^2=f-576

Step 4. Divide everything now by -16:

-16t^2/-16=f/-16-576/-16

Step 5. Simplify again:

t^2=-f-576/16

Hope I could help! :)
