5 0

Answer:

y = -10

Step-by-step explanation:

−3(y+5)=15

Divide each side by -3

−3/-3(y+5)=15/-3

y+5 = -5

Subtract 5 from each side

y+5-5 = -5-5

y = -10

A grandfather clock’s pendulum has a period of 4.5 seconds. What is its frequency? Round to the nearest hundredth.
Brilliant_brown [7]

Answer: 0.22hz

Step-by-step explanation:

Hi to answer this question we have to analyze the information given:

  • <em>Period (T) = 4.5 Seconds </em>

So, to calculate the frequency of the pendulum we have to apply the formula;

Frequency (f)= 1 / period  

Replacing with the value given:

f = 1/ 4.5 sec = 0.22 hz

Feel free to ask for more if needed or if you did not understand something.
