Answer:

Length of the minor arc AB = 5.27777777778 cm

Step-by-step explanation:

Here you would require a simple proportionality.

The ratio of the degree of the minor arc (95 degrees) over the total, 360 degrees of every circle, comparative to the length of the minor over the circumference (20 cm).

Here we can propose that the length of the minor can be equal to x.

Now let's substitute the known values:

95 / 360 = x / 20

Now cross multiply:

360 * x = 95 * 20 ⇒

360x = 1900 ⇒

x = 5.27777777778 ⇒

length of the minor arc AB = 5.27777777778 cm

Which of the following inverse functions are defined for x=-1/2? Select all that apply.
Aleksandr-060686 [28]

Answer:

A, B, E, and F  

Step-by-step explanation:

sinx and cosx are defined for all values of x. So, sin⁻¹x and cos⁻¹x  are also defined for all values of x.  

A and E are correct.

tanx is defined for all values of x.

However, tan(nπ) = 0 at when n is an integer. So, tan⁻¹(±nx) is undefined. However, tan⁻¹(-½x) is defined, because -½ is not an integer.

B and F are correct.

C and D are <em>wrong</em>. Both sec⁻¹x  and csc⁻¹x are undefined when -1 < x < 1, and -½ is in this forbidden region.

(B). A physical change takes place that causes molecules to move faster

Step-by-step explanation:

When a bar of chocolate melts its physical form is changed, there is no difference in its chemical composition as it is still same.

When the chocolate bar was frozen its molecules were held strongly, and they were barely moving, whereas when it melts the molecules are more free to move now.
