Answer:
No.
Step-by-step explanation:
This type of problem is actually a trick problem. The question indicates that the PRODUCT of 3.93 and 0.07 would be about 4. The question is referring to the answer of the two values Multiplied to each other.
To visualize the question, we have:
3.93 x 0.07
This would give us:
0.2751
Kerri would be correct if she was looking for the SUM of the two values.
This would be:
3.93 + 0.07
This would give us:
4
Therefore in trick problems like this ones, it is better to look at what exactly is being asked.
Answer:
Part 1
Multiply both sides by 2π
2πf = √(g/L)
Square both sides
4π²f²= g/L
Invert both sides
1/(4π²f²) = L/g
Multiply both side by g
g/(4π²f²) = L
We usually write an equation with the subject (L) n the left
L = g/(4π²f²)

Part 2
Using the above equation with the given values:
L = g/(4π²f²)
. .= 9.8 / (4π² x 1.6²)
. .= 0.097m (= 9.7cm)

By the way, where it says
“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”
this should say
“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”
Step-by-step explanation:
This problem is basically
If I plug in n = 16 and r = 9
So there are 4151347200 different nine player batting orders that can be chosen from a baseball team of 16 :)
