Answer:
Period = 4.5 seconds
Frequency = 0.22 hertz.
Step-by-step explanation:
Given : 10-pound weight oscillating (as a pendulum) on a 5-meter-long rope.
To find : What is the period and frequency.
Solution :
The formula to find time when length is given,
where,T is the time period , L is the length and g is the acceleration due to gravity
L= 5 m and g=9.8 m/s
Substitute in the formula,
The time period is approx 4.5 seconds.
Therefore,Period = 4.5 seconds
Frequency is 0.22 hertz.
B. f(4) = g(-2)
C. f(2) = g(-2)
D. f(-2) = g(-2)
Answer:c. F(2)=g(-2)
Step-by-step explanation:
Let's use the information given to create an inequality for Mary's age (represented as x):
↪ Emily is three years older than twice Mary's age, so Emily's age is 2x + 3.
↪ The sum of their ages is less than 30, so we can write an inequality:
Now, We can simplify the inequality:
Subtract 3 from both sides of the inequality:
Now, divide both sides by 3 to isolate x:
So, Mary's possible age (represented by x) is less than 9. The inequality that represents Mary's possible age is: x < 9.
Answer:
(a+b)^2=a^2+2ab+b^2
The given expression is that -3ab
100-3*16=100-48=52
52 it is.
game. The game cost $54.79. He
started the day with $210 in his bank
account. Looking at his receipts, he
has spent $87.35 at a clothing store,
$42.79 at a party store, and $25.68
at a gas station. Does he have enough
money to buy the video game? Beyond
estimating, explain your answer
mathematically.
Answer:
Justin does not have enough money because if you add up all the numbers you were given you get 155.82 and have 54.18 and the game costs 54.79. he is 61 cents off.
