The change from 10 to 11 or from 100 to 101 is 1 in each case.

In the first case, the percentage of change is 1/10 = 10%.

In the second case, the percentage of change is 1/100 = 1%.

The percentages of change are different because the bases from which the change is measure are different.

Answer:

B. $6\sqrt2$

Step-by-step explanation:

Given:

The given triangle is an isosceles right angled triangle with the legs equal to 6 cm each and the hypotenuse is 'x' cm.

Applying Pythagoras theorem which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Therefore,

$x^2=6^2+6^2\\x^2=36+36\\x^2=72\\x=\sqrt{72}\\x=\sqrt{36\times 2}\\x=\sqrt{36}\times \sqrt{2}\\x=6\sqrt2\ cm$

Therefore, the length of the hypotenuse is $x=6\sqrt2$ cm.

Hence, the option B is the correct one.

Identify the zeros of the function f(x) =2x^2 − 2x + 13 using the Quadratic Formula. SHOW WORK PLEASE!! I NEED HELP!!

Answer:

$x=\frac{1+5i} {2}$ and $x=\frac{1-5i} {2}$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$f(x)=2x^{2} -2x+13$

Equate the function to zero

$2x^{2} -2x+13=0$

$a=2\\b=-2\\c=13$

substitute in the formula

$x=\frac{-(-2)\pm\sqrt{-2^{2}-4(2)(13)}} {2(2)}$

$x=\frac{2\pm\sqrt{-100}} {4}$

Remember that

$i=\sqrt{-1}$

$x=\frac{2\pm10i} {4}$

Simplify

$x=\frac{1\pm5i} {2}$

therefore

$x=\frac{1+5i} {2}$ and $x=\frac{1-5i} {2}$
