Nhân đa thức đối xứng

(2\sqrt{3} -4)/(\sqrt{3} -1) + (2\sqrt{2} -1)/(\sqrt{2} -1) - (1+\sqrt{6} )/(\sqrt{2} +3)

=(2\sqrt{3} -4)(\sqrt{3} +1)/(\sqrt{3} -1)(\sqrt{3} +1) + (2\sqrt{2} -1)(\sqrt{2} +1)/(\sqrt{2} -1)(\sqrt{2} +1) - (1+\sqrt{6} )(\sqrt{2} -3)/(\sqrt{2} +3)(\sqrt{2} -3)

=3-\sqrt{3} -2+4+\sqrt{2} -1 +(\sqrt{2} -3+2\sqrt{3} -3\sqrt{6} )/7

= 2.900712176

Teresa runs 7 miles in 80 minutes. At the same rate, how many miles would she run in 64 minutes?
sveta [45]

Answer:

She would run about 5.8 miles in 64 min.

Step-by-step explanation:

Let m= miles per minute

7=80m divide 80 on both sides.

0.0875=m Round

0.09 miles per minute

0.09 x 64= 5.76 round or leave it like that

Name the relationship <br> A.complementary <br> B.linear pair<br> C.vertical<br> D.adjacent
Tom [10]

Answer:

∠a and ∠b are the adjacent angles.

Therefore, option D i.e. adjacent is the correct option.

Step-by-step explanation:

Given the angles

  • ∠a
  • ∠b

We know that the two angles are termed as the adjacent angles when they share the:

  • common vertex
  • common side

From the given diagram, we are given the angles ∠a and ∠b.

It is clear that angles ∠a and ∠b have a common vertex and common side.

Therefore, the relationship between the angles ∠a and ∠b is 'adjacent'.

In other words, ∠a and ∠b are the adjacent angles.

<em />

<u><em>Please note that the given relation can not be a 'linear pair' because the sum of two angles is NOT a straight line or 180°.</em></u>

<u><em /></u>

Therefore, option D i.e. adjacent is the correct option.

A quadratic function has a vertex at (2,5) and passes through the point (4,9).
uranmaximum [27]
Since another way to write an equation for a parabola is a(x-h)^2-k, with h and k as the vertex points, we can plug that in to get a(x-2)^2-5. To find a, we plug 4 in and have 9 as what it equals, getting a(4-2)^2-5=9=4a-5=9 and 4a=14, where a=14/4. Therefore, the equation would be (14/4)(x-2)^2-5
