Answer:

x = 60°, 120°

Step-by-step explanation:

If we let t=2x, our equation now becomes \cos{t}=-1/2, which is true for two values of t: 120° and 240°. Since t = 2x, we can say that 120^{\circ}=2x and 240^{\circ}=2x, and therefore x = 60^{\circ} and x=120^{\circ}

2. explain what is meant by (distribution) transparency and give examples of different types of transparency.
konstantin123 [22]

The phenomena of hiding distribution characteristics in a system from applications and users is known as distribution transparency. Access transparency, location transparency are some examples.

<h3>Define the term (distribution) transparency?</h3>

Distributed databases have the attribute of distribution transparency, which keeps consumers from knowing the internal workings of the distribution.

  • The DDBMS designer has the option of replicating table fragments, storing them at several locations, and fragmenting tables.
  • There are numerous distribution methods. Systems that need a wide range of management systems to pinpoint the source of resources, a product, or a service delivery process from the end user.
  • Typically, the distributor, seller, or producer is responsible for maintaining transparency to track the many points at which resources, goods, or services are delivered.
  • Accounting supplied by any intermediary company in the product, service, or resource flow is, of course, the usual approach to determine the degrees of value added through distribution management.

Thus, access transparency, location transparency are some examples of the (distribution) transparency.

Help!<br><br> If a sphere has a radius of 8mm, what is its volume? (Show work)
babymother [125]
The formula for the volume of a sphere is V = (4/3) * π * r³. Knowing this, we can plug in the radius:

V = \frac{4}{3} \pi *8^{3} \\ V = \frac{4}{3} \pi*512 \\ V = 2144.66

The sphere's volume is approximately 2144.66 mm^3.
