Simplify nine square root of two minus three square root of seven plus square root of eight minus square root of twenty eight.

avanturin [10]

Answer:

$11\sqrt{2} - 5\sqrt{7}$

Option (A) is the correct answer.

Step-by-step explanation:

$9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

Now, $\sqrt{8} = \sqrt{2 \times 2 \times 2} = 2\sqrt{2}$

$\sqrt{28} = \sqrt{2 \times 2 \times 7} = 2\sqrt{7}$

∴ $9\sqrt{2} - 3\sqrt{7} + \sqrt{8} - \sqrt{28}$

= $9\sqrt{2} - 3\sqrt{7} + 2\sqrt{2} - 2\sqrt{7}$

= $9\sqrt{2} + 2\sqrt{2} - 3\sqrt{7} - 2\sqrt{7}$

= $11\sqrt{2} - 5\sqrt{7}$

Therefore option (a) is the correct answer.

For which value(s) of the constant k is the circle x² + (y − k)² = 16 tangent to the line y = 3?

<em>Step-by-step explanation:Let us find points of intersection of line </em>

<em>3 </em>

<em>x </em>

<em>+ </em>

<em>4 </em>

<em>y </em>

<em>− </em>

<em>k </em>

<em>= </em>

<em>0 </em>

<em> and circle </em>

<em>x </em>

<em>2 </em>

<em>+ </em>

<em>y </em>

<em>2 </em>

<em>= </em>

<em>16 </em>

<em>. We can do this by putting value of </em>

<em>y </em>

<em> from first equation i.e. </em>

<em>y </em>

<em>= </em>

<em>k </em>

<em>− </em>

<em>3 </em>

<em>x </em>

<em>k </em>

<em>x </em>

<em>+ </em>

<em>k </em>

<em> </em>

<em>This would give two values of </em>

<em> and corresponding two values of </em>

<em> i.e. two points. But tangent cuts the circle in only at one point. This will be so when discriminant is zero i.e. </em>

the area of a square floor on a scale drawing is 100 square centimeters, and the scale of the drawing is 1 cm: 2 ft. what is the

kondaur [170]

The square root of 100 is 10. The drawing must be 10 cm by 10 cm.

1 cm = 2 ft, so 10 cm must equal 20 feet.

20 * 20 = 400 square feet :)

Which board geometrically represents 4x2 – 1 using algebra tiles? An algebra tile configuration showing only the product spot, w

NemiM [27]

An algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

The correct option is B.

Given

Equation; $\rm 4x^2 - 1$

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero.

Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

4x² -1 = 0 is a quadratic equation.

An algebra tile configuration showing only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.

Then,

The factors of the polynomial is;

$\rm 4x^2 - 1=0\\\\ 4x^2-2x+2x-1=0\\\\ 2x(2x-1)+1(2x-1)=0\\\\(2x-1)(2x+1)=0$

Hence, an algebra tile configuration shows only the product spot, which has 9 tiles in 3 columns with 3 rows. First row: 2 + x squared, 1 + x. Second row: 2 + x squared, 1 + x. Third row: 2 negative x, 1 negative.
