Answer:

\frac{\bf{cd^7}}{\bf{c^6d \cdot c^4d^9}}=\frac{\bf{1}}{\bf{c^9d^3}}

Step-by-step explanation:

Given expression is \frac{cd^7}{c^6d \cdot c^4d^9}

\frac{cd^7}{c^6 d \cdot c^4d^9}=\frac{c d^7}{c^{10}d^{10}} by using the formula a^m+a^n=a^{(m+n)}

\frac{c d^7}{c^6 d\cdot c^4d^9}=\frac{c}{c^{10}}\cdot\frac{d^7}{d^{10}}

\frac{c d^7}{c^6 d\cdot c^4d^9}=\frac{c^-9}{d^-3} by using the formula  \frac{a^m}{a^n}=a^{(m-n)}

\frac{c d^7}{c^6 d\cdot c^4d^9}=\frac{1}{c^9d^3} by using the formula  \frac{1}{a^m}=a^{-m}

Which transformation would change the point (5,3) into (-5,3)?
alexandr1967 [171]
A transformation like this would be a reflection across the Y access. If you flip this point about the Y access, the Y will not change but you will get the inverse of the X.
Hope this helps! :D

lbvjy [14]
So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.


3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.

3.54/3=1.18
10^7/10^8=1/10

Now we just multiply our answers together because we separated them before we divided.

1.18*1/10=.118

So the answer is .118 seconds
