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)”

Answer:
4b this is the correct answer yes
Answer:
-7
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
-2 - 5 = -7
Check by subtracting the second term from the third term
-9 - (-2) = -9+2 = -7
The common difference is -7
Answer:
7.97 is the median
Step-by-step explanation:
Answer:
4 units
Step-by-step explanation:
see attachment for the missing figure.
to find the value of AY or x
We'll use intersecting chord theorem i.e the product of line segment of each chord are equal.
From the figure, we can say that:
BY x YD = AY x YC
Therefore, AY = 4 units
