b. what is the maximum height the ball will reach
c. find the number of seconds the ball is in the air when it reaches 224 ft in height
d. after how many sec. will the ball hit the ground before rebound?
I am not sure which equation to use and why for the b,c,and d. If I find the ft/sec. that the ball travels (96), and set the quadratic equation to -16t^2+144t+288 or 16t^2-144t-288=0, is this correct? Or should I use the quad formula and why.
Answers
the maximum height of the ball will be where the derivative is zero. In other words you could find the height of the ball by converting this into vertex form, or you could find it by calculating the time needed for the ball to reach its maximum height.
0=-32t+144
t=3 till max and max is 288
224=-16t^2 +144t
0= -16t^2+144t-224
t=2 but then the ball will reach 224 ft again at t=7
the ball reaches its maximum height at t=3 seconds and a parabola is symmetric, so at t=6 seconds it will contact the ground again.

Question:
To control the pandemic, people have been restricted from leaving their homes. This measure is called quarantine and is one of the main ways to decrease the number of infections. The exit restrictions that have been taken are the following: o
• A: In Guayaquil, the first week you could not leave home from 12:00 to 6:00.
• B: In the rest of the country, the first week you could not leave home from 8:00 p.m. to 6:00 a.m.
• C: In the whole country, from the third week onwards you cannot leave the house from 2:00 pm to 6:00 am.
• D: If the cases of contagion continue to increase potentially, a 24-hour restriction would be considered. Activities 1. Represent in the form of an interval and on the number line the 4 cases of restrictions posed.
2. Solve the interval corresponding to the following operations: A∪B; C∩D
Step-by-step explanation:
1. The time in Hours is represented on the number line.
A) Restrictions From 12.00pm until 6.00am
In hours: 0 to 6.00am; 12.00pm to 24.00pm
(0, 6); (12, 24)
B. Restriction from 8.00pm to 6.00am
In hours: 20:00pm to 24.00pm; 0 to 6:00 am
(0, 6); (20, 24)
C. Restriction from 2.00pm to 6.00am
In hours: 14:00pm to 24.00pm; 0 to 6:00am
(0, 6); (14, 24)
D. 24hr restrictions
In hours: 00:00am until 24:00pm
(0, 24)
2. From the graph,
A ∪ B = (0, 6) ∪ (12, 24)
C ∩ D = (0, 6) ∩ (14, 24)
Where '∪' mean the union of A and B. That is, we combine all the element of A and B together.
And '∩' mean the intersection of C and D. That is we pick the values common to C and D.
Equation B: 4y = 2 − 4z
Step 1: −4(y) = −4(4 − 2z) [Equation A is multiplied by −4.]
4y = 2 − 4z [Equation B]
Step 2: −4y = 4 − 2z [Equation A in Step 1 is simplified.]
4y = 2 − 4z [Equation B]
Step 3: 0 = 6 − 6z [Equations in Step 2 are added.]
Step 4: 6z = 6
Step 5: z = 1

Rewrite the original equation as:
Log(4x^2) - log(3yz)
Rewrite log(4x^2) as log(4) + log(x^2)
Rewrite log(4) as 2log(2)
Rewrite log(x^2) as 2log(x)
Separate log(3yz) into 3 logs: log(3), log(y) and log(z)
Now combine them to get:
2log(2) + 2log(x) - log(3) - log(y) - log(z)
Final answer:
The decomposition of the logarithmic expression Log((4)/(3yz)) leads to the end result: Log(4) + Log(
) - Log(3) - Log(y) - Log(z). The given expression is separated into individual logarithms applying the logarithmic rules.
Explanation:
The decomposition of the logarithmic expression Log((4x2)/(3yz)) according to the laws of logarithms can be done as follows:
Using the rule that log(a/b) = log(a) - log(b), we can first split the expression into two parts: Log(4x2) - Log(3yz).
From there, we can apply the rule that log(ab) = log(a) + log(b) to split these further. So, Log(4x2) becomes Log(4) + Log(x2), and Log(3yz) becomes Log(3) + Log(y) + Log(z).
Finally, we substitute these back into the original expression to get the final decomposition: Log(4) + Log(x2) - Log(3) - Log(y) - Log(z).

The nucleus is like the brain of the cell, where genetic information is located and stored. It can’t be the mitochondria because that’s where ATP (energy) is generated. It can’t be the ribosomes because that is the area of informational decoding. It can’t be the lysosomes because that is the area of virus destruction.
