Answer:

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

Step-by-step explanation:

We need to find mistake make in work below:

$(-2x^4)^4=-16x^{16}$

The mistake here is when we have even power, the negative sign gets positive i.e $(-a)^m=a^m$ if m is even

so, in our case it would be:

$(-2x^4)^4=16x^{16}$

The correct choice is:

-2 to the 4th power is positive 16.

Option C is correct.

12. Use a trigonometric ratio to find the measure of O in the triangle below. Give your answer to the nearest degree.

Given :-

A right angled triangle with two sides 10cm and 9cm .

To Find :-

The value of theta .

Solution :-

At angle theta , 9cm side will be considered as the perpendicular and 10cm side will be hypotenuse . So , as we know that ;

$\longrightarrow sin\theta =\dfrac{perpendicular}{hypotenuse}$

Substituting the respective values,

$\longrightarrow sin\theta =\dfrac{9cm}{10cm}$

Simplify,

$\longrightarrow sin\theta= 0.9$

Take arcsin both sides ,

$\longrightarrow \theta =sin^{-1}(0.9)$

$\\\longrightarrow\underline{\underline{\theta = 64.15^o }}$

Hence the required answer is 64.15° .
