Answer:
it's 9.947
Step-by-step explanation:
for this we need an equation which contain height in it so we used volume in both so we get height
π2^2h=5*5*5
π4h=125
h=9.947
Answer:
After 16 rounds the champion of Ping-Pong player can be determined.
Step-by-step explanation:
This is an example of geometric progression,
First term = 65,536
Now we need to find which term is 1 in this GP.
N th term of GP is given by
Substituting
Seventeenth term of this GP is 1.
That is after 16 rounds the champion of Ping-Pong player can be determined.
Should be the last one, 43, 52, 61.
Answer:
19.
h=0, the result is 1000×2⁰ = 1000
this is the population of bacteria the excitement started with at the very beginning.
h=-3, the result is 1000×2-³ = 1000/(2³) = 1000/8 = 125
this is a calculation 3 hours backwards from the very start of the experiment, saying that if we started the experiment 3 hours earlier, this would have had to be the starting population of the bacteria so we would arrive at the same amount of population at any given time (value of h).
20.
D 25x⁶
Step-by-step explanation:
for 19 there is not more explanation. it is all ashtray in the answer.
for 20 we see that we are dealing with a square, so ask 4 sides have the same length.
one side is 5x³.
the area of a square is simply side².
so, here (5x³)² = 25x⁶
