Strike441 [17]

Answer:

The number of eggs in the basket is 56

Step-by-step explanation:

Given as :

Let The number of eggs in the basket = 3x + 5x

When Loza counts 3's , there are 2 eggs left over

I.e , 3 ( x - 2 )

And When Loza counts 5's , there are 4 eggs left over

I.e 5 ( x - 4 )

∴ 3 x - 6 = 5 x - 20

Or, 20 - 6 = 5 x - 3 x

Or, 14 = 2 x

∴ x = 7

So, the number of eggs = 3 × 7 + 5 × 7

= 21 + 35 = 56

Hence The number of eggs in the basket is 56 Answer

Find all values of x in the interval [0,2π] that satisfy the equation sin2x=cosx. enter your answers as a list of numbers separa

yuradex [85]

$\sin(2x) = \cos(x) \\ 2 \sin(x) \cos(x) = \cos(x) \\ \cos(x) (2 \sin(x) - 1) = 0$
so
$\cos(x) = 0 > > > x = \frac{\pi}{2} + k\pi \\ \sin(x) = \frac{1}{2} > > > x = \frac{\pi}{6} + 2k\pi \\ or \: x = \frac{5\pi}{6} + 2k\pi$
$x = \frac{\pi}{2} or \frac{3\pi}{2} \\ x = \frac{\pi}{6} or \frac{5\pi}{6}$
