Answer:

3\frac{4}{5} pounds of food

Step-by-step explanation:

We have been given that Rodney bought a 25-pound bag of dog food. His dog ate 10\frac{2}{5} pounds of the food in the first month and 10\frac{4}{5} pounds in the second month.  

Let us find the amount of dog-food eaten by dog in two months.

\text{Dog-food eaten in 2 months}=10\frac{2}{5}+10\frac{4}{5}

\text{Dog-food eaten in 2 months}=\frac{52}{5}+\frac{54}{5}

\text{Dog-food eaten in 2 months}=\frac{52+54}{5}

\text{Dog-food eaten in 2 months}=\frac{106}{5}

Now we will subtract amount of food eaten by dog from the amount of food initially to find the remaining amount of dog food.

\text{Remaining amount of dog-food}=25-\frac{106}{5}

\text{Remaining amount of dog-food}=\frac{5*25}{5}-\frac{106}{5}

\text{Remaining amount of dog-food}=\frac{125}{5}-\frac{106}{5}

\text{Remaining amount of dog food}=\frac{125-106}{5}

\text{Remaining amount of dog food}=\frac{19}{5}

\text{Remaining amount of dog food}=3\frac{4}{5}

Therefore, 3\frac{4}{5} pounds of food was remaining in the bag at the end of the two months.

3 4/5 pounds left.
10 2/5 + 10 4/5 = 21 1/5.
25 - 21 1/5 = 3 4/5.

Use DeMoivre's theorem to evaluate the expression
natima [27]

Answer:

B. \dfrac{9}{2}-i\dfrac{9\sqrt{3}}{2}

Step-by-step explanation:

DeMoivre's theorem:

If the complex number z=r(\cos \alpha+i\sin\alpha), then for natural number n

z^n=r^n(\cos n\alpha+i\sin n\alpha).

In your case,

z=\sqrt{3}\left(\cos\dfrac{5\pi}{12}+i\sin\dfrac{5\pi}{12}\right)

and you have to evaluate z^4.

By DeMoivre's theorem,

z^4=(\sqrt{3})^4\left(\cos 4\cdot \dfrac{5\pi}{12}+i\sin 4\cdot \dfrac{5\pi}{12}\right)=9\left(\cos \dfrac{5\pi}{3}+i\sin\dfrac{5\pi}{3}\right)=9\left(\dfrac{1}{2}-i\dfrac{\sqrt{3}}{2}\right)=\dfrac{9}{2}-i\dfrac{9\sqrt{3}}{2}.

Please solve and explain steps for this problem.
Helen [10]
This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.
