Answer:

1 and 3 are irrational!!! The others are all rational

Step-by-step explanation:

1 and 3 are never terminating and they are not repeating, therefore, they are irrational! All the others are either terminal (they have a decimal that stops) or they are repeting and those repeting numbers can be written as a fraction, for example 0.2222... can be written as 2/9

(1 - cosx) (1 + 1/cosx) = sinxtanx

Nataly [62]

Answer:

cos x ≠ 0 ⇔ x ≠ $\frac{pi}{2}+k.pi$ ; k ∈ N

$(1-cosx)(1+\frac{1}{cosx})=sinx.tanx\\\\(1-cosx)(\frac{cosx+1}{cosx})=sinx.\frac{sinx}{cosx}\\\\ \frac{1-cos^{2} x}{cosx} =\frac{sin^{2}x }{cosx}\\\\=>1-cos^{2}x=sin^{2}x$

<=> cos²x + sin²x = 1

⇔ 1 = 1

=> x = { R \ (pi/2 + k.pi); k ∈ N}

At x=0 y=6 the y intercept. The rate is -0.25 so the equation is y=6-0.25x. The ordered pair is (x,6-0.25x).

IrinaK [193]

Answer:

x + y = 15

y = 3x + 1.5

x + (3x + 1.5) = 15

Step-by-step explanation:

Let :

Soft ball practice = x

Soccer practice = y

y = 3x + 1.5

Total practice time :

x + y = 15 - - - (1)

x + 3x + 1.5 = 15

4x + 1.5 = 15
