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.
Answer:

Step-by-step explanation:
- the given expression is : −4≤11−3x
- we use following operations to solve the inequality:
- by adding 4 on both sides, the inequality will become :
-4+4 ≤ 11-3x +4
0 ≤ 15 -3x
- adding 3x on both sides, the inequality will become:
3x ≤ 15
- dividing both the sides of the inequality by 3, the inequality will become:
3x/3 ≤ 15/3
x ≤ 5 ( since, 15/3 = 5)
- therefore the solution for x as an inequality will be x ≤ 5
An expression for the height of the nth bounce is 0.80X^N = Height.
<h3><u>Equations</u></h3>
Since when dropped, a super ball will bounce back to 80% of its peak height, continuing on in this way for each bounce, to determine an expression for the height of the nth bounce the following calculation must be performed:
- X = Initial value
- 80% = 0.80
- N = Number of times the ball bounces
- 0.80X^N = Height
Therefore, an expression for the height of the nth bounce is 0.80X^N = Height.

Answer:
25.2
Step-by-step explanation:
2.1*12=25.2
use a calculator if you're allowed to show work that way, if not a simple way is
2.1*10=21
2.1*11=23.1
2.1*12 is equal to 2.1*10=21 because 2*12=24 and .1*12=1.2
