Answer:

\sqrt{28}

Step-by-step explanation:

You don't need to memorize all of the square roots.  Looking at each square root, find a number close to it that you know -- The square root of five is close to the square root of four, which is 2. The square root of 28 is close to the square root of 25, which is 5.  28 is a slightly bigger than 25, so the square root will be slightly greater than 5.

Write down in terms of n, an expression for the nth term
Nimfa-mama [501]

Answer:

a_{n} = - 7n - 1

Step-by-step explanation:

There is a common difference between consecutive terms , that is

- 15 - (- 8) = - 22 - (- 15) = - 29 - (- 22) = - 36 - (- 29) = - 7

This indicates the sequence is arithmetic with nth term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 8 and d = - 7 , then

a_{n} = - 8 - 7(n - 1) = - 8 - 7n + 7 = - 7n - 1

In how many ways can you arrange MATHEMATICS if duplication of the arrangement are not allowed?​
sukhopar [10]

Answer:

4989600 ways

Step-by-step explanation:

From the question,

The word MATHEMATICS can be arranged in n!/(r₁!r₂!r₃!)

⇒ n!/(r₁!r₂!r₃!) ways

Where n = total number of letters, r₁ = number of times M appears r₂ = number of times A appears, r₃ = number of times T appears.

Given: n = 11, r₁ = 2, r₂ = 2, r₃ = 2

Substitute these value into the expression above

11!/(2!2!2!) = (39916800/8) ways

4989600 ways

Hence the number of ways MATHEMATICS can be arranged without duplicate is 4989600 ways

Which angles below are complementary?
tigry1 [53]

9514 1404 393

Answer:

  ∠KXN and ∠QXT

Step-by-step explanation:

The measure of each angle is the difference of the scale values that the rays intercept. (The same scale needs to be used for each ray.) Of course, complementary angles have a sum of 90°.

Here, we'll refer to angle aXb as "ab".

  NP = 95 -35 = 60

  PQ = 35 -20 = 15  . . .  not complementary to NP

__

  KN = 165 -95 = 70

  QT = 20 -0 = 20  . . .  complementary to KN   ⇒ your answer

__

  JK = 180 -165 = 15

  PQ = 35 -20 = 15  . . . not complementary to JK

__

  JK = 15

  NK = KN = 70  . . .  not complementary to JK
