Answer: Vector Resolution
Step-by-step explanation:
Vector components can form right triangle, since one acts vertically and the other acts horizontally. Thus, the original vector forms the hypotenuse of the right triangle formed by its components.
The process of breaking a vector down into its components is called vector resolution.
Answer: 78 degrees
Step-by-step explanation:
Since the angles of a triangle have to add up to 180 degrees, and angle A is 28 degrees, and angle B is 74 degrees, angle C would have to be 78 degrees so there are a total of 180 degrees in the triangle. Since triangle ABC is similar to triangle DEF, the angle measurements of that triangle would also have to be 28 degrees, 74 degrees, and 78 degrees, corresponding to angles D, E, and F. Since the largest of these numbers is 78 degrees, and angle F is the largest angle of the triangle, that would be your answer.
Hope this helps!
B.) would be correct

ANSWER
8 minutes
EXPLANATION
We know that the cost of using the internet in dollars is given by,

Where x is the number of minutes spent on the internet.
In this problem, we have to find how many minutes will 6 dollars buy. In other words, we have to find x for y = 6. To solve the given equation for x, we have to multiply both sides by 4,

And divide both sides by 3,

So, for y = 6, x is,

Hence, $6 will buy 8 minutes.
