Which table represents a direct variation function?
2 answers:
Answer:
The correct option is 3.
Step-by-step explanation:
A function is direct variation function if
where, k is the constant of proportionality.
It means the value of y is k times of x. Only table 3 represents a direct variation function because each value of y is -2 times of x.
At x=-5,
At x=-4,
At x=-3,
At x=-2,
At x=-1,
Therefore the correct option is 3.

Answer:
Minor arc BC - 130° (arc at which inscribed angle is subtended)
The major arc BC - 230°
Step-by-step explanation:
Angle BDC is inscribed angle subtended on the arc BC.
The measure of the angle BDC is 65°.
The Central Angle Theorem states that the central angle from two chosen points B and C on the circle is always twice the inscribed angle from those two points.
By the central angle theorem, the measure of central angle BOC (O is the center of the circle) has the measure of
Hence, the minor arc BC has the same measure as the central angle BOC that is 130°.
The major arc BC has the measure
Time taken to collect 12 different state quarters is 2.5 months.
Now , we need to find time taken to collect all 50 state quarters.
Let , time required is x.
So,
Therefore, time required is 10.7 months.
Hence, this is the required solution.
