Solve: I 2x +5 I + 6 ≥ 4

Mathematics
1 answer:
masya89 [10]3 years ago
4 0

Answer:

Step-by-step explanation:

This is an absolute value problem.

If we begin a tentative solution by subtracting 6 from both sides, we get

I 2x +5 I + 6 ≥ 4  =>   I 2x +5 I  ≥ -2

Note well that  I 2x +5 I has a value of 0 or greater; it cannot be negative.

Thus  I 2x +5 I  ≥ -2 has no solution.

Answer:

sin\pi/4 * sin\pi/6 = 1/2 *(cos \pi/12 - cos 5\pi/12)

Step-by-step explanation:

Formula:- sinX sinY = (1/2) [ cos (X - Y) - cos (X + Y) ]

sin(π/4)sin(π/6)

= (1/2)[cos(π/4 - π/6) - cos(π/4 + π/6)]

= (1/2)[cos(3π/12 - 2π/12) - cos(3π/12 + 2π/12)]

= (1/2)[cos(π/12) - cos(5π/12)]

<u>Answer:</u>

The variable that has the highest power is considered to be the degree of polynomials in an algebraic equation.

A column:

1) 4x^3 .

The degree is 3.

2)x^2+4.

The degree is 2.

3) x-2

The degree is 1.

B column:

1) 2x^2+1

The degree is 2.

2) x^2-x

The degree is 2.

3) x^3-5x^2+1

The degree is 3.

A×B columns:

While Multiplying two terms in a equation, if the variables are same then multiply the constant value and sum the exponent value.

1) (4x^3)(2x^2+1).

=8x^5+4x^3.

The degree is 5.

2) (x^2+4)(x^2-x).

=x^4-x^3+4x^2-4x.

The degree is 4.

3) (x-2)(x^3-5x^2+1).

=x^4-5x^3+x-2x^3+15x^2-3.\\=x^4-7x^3+15x^2+x-3.

The degree is 4.
