Answer:

$=-12$

$d(u,v)=2\sqrt{31}$

Step-by-step explanation:

We are given that inner product defined on $R_n$

$=3u_1v_1+u_2v_2$

u=(0,-4),v=(5,3)

We have to find the value of <u,v> and d(u,v)

We have $u_1=0,u_2=-4,v_1=5,v_2=3$

Substitute the value then we get

$=3(0\cdot5)+(-4)(3)=-12$

Now, $d(u,v)=\left \|v-u\right \|$

Using this formula we get

$d(u,v)=\left \| (5,7) \right \|=\sqrt{3(5)^2+(7)^2}=\sqrt{75+49}=\sqrt{124}$

$d(u,v)=2\sqrt{31}$

What is BC?<br><br> ___ units

Okay. First off, let’s solve for the first two sides, since they are the same length. Set it up like this: 8x - 4 = 5x + 11. Subtract 5x from both sides to get 3x - 4 = 11. Next, add 4 to both sides to get 3x = 15. Now, divide each side by 3 to isolate the x and you get 5. Let’s plug in the values. 8 * 5 = 40 - 4 = 36. 5 * 5 = 25 + 11 = 36. There. x = 5. Now, let’s plug the 5 in to the other formula. 5 * 4 = 20. 20 - 2 = 18. There. BC is 18 units long.

How can i solve this exponent

Firdavs [7]

$\frac{p^2n^4(p^{10}n^5)^{\frac{2}{5}}}{(p^{-8}n^3)p^{12}n^5} = \frac{p^2n^4p^{10\times \frac{2}{5}}n^{5\times \frac{2}{5}}}{(p^{-8+12}n^{3+5})} = \frac{p^2n^4 p^4n^2}{p^4n^8}= \frac{p^6n^6}{p^4n^8}= \frac{p^2}{n^2}$

( 4 over 4 )x = 4/32 what is the value of x

aksik [14]

4 over 4 (4/4) is equal to 1.

The equation can be rewritten as X = 4/32

4/32 can be simplified to 1/8

So you have X = 1/8
