arcsin(1/2) means "the angle whose sine is 1/2".

That's 30° .

y = cos(30°) = (1/2)√3 = about 0.866 .

What is the closest perfect square greater than 54
Anna35 [415]

Answer:

64

Step-by-step explanation:

Perfect squares are integers multiplied by themselves.

  • 2 times 2  = 4
  • 3 times 3  = 9
  • 4 times 4  = 15

The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).

49 is less than 54, so that's ruled out.

Therefore, the closest perfect square to 54 that is greater than it is 64.

X4 – 17x2 + 16 = 0 Rewrite the equation in terms of u
slavikrds [6]
You probably are interested in expressing the given equation as a quadratic equation in u, as it will make it easy to find the solutions.

Let u = x²
So,
u² = x⁴

So, the given equation can be written as:

u² - 17u + 16 = 0

Now the equation is quadratic in u and the solutions can be calculated using quadratic formula or factorization.

They're all d).

1) 28>24=10+14

2) Either 96/8=? or 8*?=96 describe the problem, ? being the number of chairs (the blank square in the answers). Of the two only the first appears in the options.

3) This question is ambiguous: if someone went both days, we could say the total number of people who went to the Saturday and Sunday games would be less than 3271+5844=9115. But who wrote the question likely wanted you to just do the sum between the two numbers, so of all options d is likely what they want you to choose.
