NEED HELP ASAP PLEASE WITH #7!!
AnnZ [28]

Answer:

The answer to your question is: The second option

Step-by-step explanation:

Points A (3 , 7)     B (5, 11)

slope = m = (y2 - y1) / (x2 - x1)

m = (11 - 7) / (5 - 3)

m = 4 / 2 = 2

equation if the line

  (y - y1) = m(x - x1)

 (y - 7) = 2(x - 3)      Answer

Can someone help me pls
Wittaler [7]

Answer:

3 cm

Step-by-step explanation:

  • V_{cylinder} = 189\pi \: cm^3 (Given)

  • h_{cylinder} = 21\: cm (Given)

  • Formula for V_{cylinder} is given as:

  • V_{cylinder} = \pi r^2h

  • \implies  189\pi = \pi r^2(21)

  • \implies \frac{ 189\pi}{21\pi} = r^2

  • \implies 9 = r^2

  • \implies \pm\sqrt 9 = r

  • \implies \pm 3 = r

  • Length of radius can not negative

  • \implies r = 3 \: cm

Hope it helps you in your learning process.

Let W be the subspace of R5 spanned by the vectors w1, w2, w3, w4, w5, where
Gwar [14]
To find W⊥, you can use the Gram-Schmidt process using the usual inner-product and the given 5 independent set of vectors. 

<span>Define projection of v on u as </span>
<span>p(u,v)=u*(u.v)/(u.u) </span>
<span>we need to proceed and determine u1...u5 as: </span>
<span>u1=w1 </span>
<span>u2=w2-p(u1,w2) </span>
<span>u3=w3-p(u1,w3)-p(u2,w3) </span>
<span>u4=w4-p(u1,w4)-p(u2,w4)-p(u3,w4) </span>
<span>u5=w5-p(u4,w5)-p(u2,w5)-p(u3,w5)-p(u4,w5) </span>

<span>so that u1...u5 will be the new basis of an orthogonal set of inner space. </span>

<span>However, the given set of vectors is not independent, since </span>
<span>w1+w2=w3, </span>
<span>therefore an orthogonal basis cannot be found. </span>
