Answer:

20

Step-by-step explanation:

we know that 414-360 = 54 and we divide it by 3, 54/3 = 18. So we know that every student paid 18 dollars. 360/18 = 20

  • Let total students be x
  • Students didn't came to lunch be y

ATQ

  • x+y=414---(1)
  • x-y=360--(2)

Substracting both

\\ \sf\longmapsto 2y=54

\\ \sf\longmapsto y=27

  • 3 students paid 27

each paid

\\ \sf\longmapsto \dfrac{27}{3}=9

Now

Total students went on trip

\\ \sf\longmapsto \dfrac{360}{9}

\\ \sf\longmapsto 40

Find the value of x. If​ necessary, write your answer in the simplest radical form.
Paul [167]

Answer:

x = 4\sqrt{5}

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 1² = 9²

x² + 1 = 81 ( subtract 1 from both sides )

x² = 80 ( take square root of both sides )

x = \sqrt{80} = \sqrt{16(5)} = \sqrt{16} × \sqrt{5} = 4\sqrt{5}

What is the value of e^infinity and e^-infinity
valentinak56 [21]
E^(∞): This is defined as 'e' being raised to a huge value. Hence the result will definitely be a large number which is also infinity (∞), i.e. e^(∞) = ∞. e^(- ∞) = 1/e^(∞) = 1/∞ = 0.
