Answer:
Chris will take 0.75 seconds to return to his starting height of 10 feet.
Step-by-step explanation:
Let the height of Chris be represented by 
, where 
is the height in feet and 
, the time in seconds. First, we equalize the formula to a height of 10 feet and simplify the resulting expression, that is:
Then, we simplify the expression by algebraic means:
Roots of the polynomial are, respectively:
First root represents the initial height of Chris, whereas the second one represents the instant when Christ returns to the same height above the surface of the water. Hence, Chris will take 0.75 seconds to return to his starting height of 10 feet.
The answer is letter A. A meter has nearly the same value to a yard, one yard approximately amounting to 1.09361 meter. The rest of the other measures are far from meter's value in distance.

2. Using the external angle of a triangle theorem.
6x - 17 = 3x - 11 + 2x + 11
6x - 5x = 17
x = 17
So m angle K = 2(17) + 11
= 45 degrees answer
3. The diagonals are both medians of the triangle so the 2 parts are in the ratio 2:1 so 3:x = 2:1 and x = 1.5 answer
2:1
Answer:
50.27 units
Step-by-step explanation:
The formula for the circumference of a circle is:
C = 
d
where, d = diameter
Now plug in the values as shown below:
C = 16
C = 50.27
