Common ratio means the multiplier applied to a previous year to get the next year's value.
For example, production was 1000 units this year, the common ratio is 1.62, so next year production is 1.62*1000=1620, with an increase of 620 units over preceding year of 1000.
So the percentage change is 620/1000 = 0.62 = 62%.
Since O is circumscribed about quadrilateral DEFG, the value of x is equal to: D. 68°.
<h3>What is a supplementary angle?</h3>
A supplementary angle can be defined as two (2) angles or arc whose sum is always equal to 180 degrees. Mathematically, a supplementary angle can be calculated as follows:
Q + R = 180°.
In Geometry, the opposite angles of any cyclic quadrilateral that is inscribed inside a circle always form a supplementary angle. Thus, we would determine the value of x by using the mathematical expression above:
x + 112° = 180°
x = 180° - 112°
x = 68°

Answer:
t = 21
Step-by-step explanation:
The ball strikes the groujd when h = 0.

Since time must be positive, t = 21.
