Step-by-step explanation:

edge of cube = 12 cm

dimensions of cuboidal block = 1.2m × 0.72m ×0.6m  = 120cm * 72cm * 60cm

no of CUBES that can be cut out from cuboid = VOLUME of cuboid / volume of one cube

From the sum of x²+x+1 and x²-x+1, subtract -x²-x+1​

Answer»

Answer:

3x² + X + 1

Step-by-step EXPLANATION:

Sum of (x² + x + 1) and (x² - x + 1) :

→ (x² + x + 1) + (x² - x + 1)

Open the brackets.

→ x² + x + 1 + x² - x + 1

Write the COMMON terms together.

→ x² + x² + x - x + 1 + 1

→ 2x² + 2

Subtract (- x² - x + 1) from (2x² + 2) :

→ (2x² + 2) - (- x² - x + 1)

Open the bracket.

→ 2x² + 2 + x² + x - 1

Write the common terms together.

→ 2x² + x² + x + 2 - 1

→ 3x² + x + 1

  • Whenever there is a (+) sign outside the bracket, the sings of the terms doesn't CHANGES while opening the bracket.
  • Whenever there is a (-) sign outside the bracket, the sings of the terms changes while opening the bracket.

(2) A line passes through the points A (-1, 1) and B (2, 2). Without using graph, siareason, through which quadrants the line passes.​

Answer»

Step-by-step explanation:

The equation of line is y=\frac{1}{3}(x)+\frac{4}{3}. The line passing through first, second and THIRD quadrant.

Step-by-step explanation:

It is given that the line is passing through the POINTS A(-1,1) and B(2,2).

If a line passing through the two points, then the equation of line is

y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

The equation of line AB is

y-1=\frac{2-1}{2-(-1)}(x-(-1))

y-1=\frac{1}{3}(x+1)

y=\frac{1}{3}(x)+\frac{1}{3}+1

y=\frac{1}{3}(x)+\frac{4}{3}

Using slope intercept FORM we can say that the slope of the line is \frac{1}{3} and y-intercept is \frac{4}{3}.

Put y=0, to find the x-intercept.

0=\frac{1}{3}(x)+\frac{4}{3}

-\frac{4}{3}=\frac{1}{3}(x)

x=-4

Since the x-intercept is negative, y-intercept is positive and slope is positive, therefore the line passing through first, second and third quadrant.

Prove that 1 + costheta ÷ sintheta - sintheta ÷ 1 + costheta = 2cottheta

Answer»

\dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta, PROVED.

Step-by-step explanation:

To prove that, \dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta.

L.H.S. = \dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta}

Taking LCM of DENOMINATOR PART, we get

=\dfrac{(1+\cos \theta)^2-\sin^2 \theta}{\sin \theta(1+\cos \theta)}

USING the algebraic identity,

(a+b)^{2} =a^{2} +2ab+b^2

=\dfrac{1+\cos^2 \theta+2\cos \theta-\sin^2 \theta}{\sin \theta(1+\cos \theta)}

Using the TRIGONOMETRIC identity,

\sin^2 A+\cos^2 A=1

⇒ \sin^2 A=1-\cos^2 A

=\dfrac{1+\cos^2 \theta+2\cos \theta-(1-\cos^2 \theta)}{\sin \theta(1+\cos \theta)}

=\dfrac{1+\cos^2 \theta+2\cos \theta-1+\cos^2 \theta}{\sin \theta(1+\cos \theta)}

=\dfrac{2\cos^2 \theta+2\cos \theta}{\sin \theta(1+\cos \theta)}

=\dfrac{2\cos \theta(\cos \theta+1)}{\sin \theta(1+\cos \theta)}

=\dfrac{2\cos \theta}{\sin \theta}

= 2\cot \theta

= R.H.S., proved.

Thus, \dfrac{1+\cos \theta}{\sin \theta} -\dfrac{\sin \theta}{1+\cos \theta} =2\cot \theta, proved.
