Answer:
8008
Step-by-step explanation:
This is the selection of 6 elements out of 16 elements. Applying the combination formula, the total number of selections is nCr with n =16 and r =6.
16C6 = 8008
Answer: 97% growth rate.
Step-by-step explanation:
Hi, to answer this question we have to analyze exponential function:
A = P (1 + r) t
Where:
p = initial value
r = growth or decay rate (decimal form)
t= number of time intervals
A = value after t intervals
Replacing with the values given:
y=3400(1.97)^x
Where the term 1.97 = 1 + r
Solving for r:
1.97-1 = r
0.97 =r
Since the rate is positive, it is a growth rate.
To determine the percentage we have to multiply it by 100
0.97 x 100 = 97%
Feel free to ask for more if needed or if you did not understand something.
Your set the equation equal to 0 and you start factoring it, if it doesn’t factor out then you use the quadratic formula but if you do that then set it equal to “X”, not equal to 0
Given that Jerry mows 3/20 yards of lawn in 1/6 hour.
Now we have to found how much Jerry can mow per hour.
We know that "work" and "time" are in direct proportion so we can setup the ratio of work and time to easily find the required work.
Hence final answer is 
yards.
