1. Supposed that a ball is dropped from the upper observation deck of the Horizons 101 Tower 1., located
178 m above the ground. (a) What is the velocity of the ball after 5 sec? (b) How fast is the ball traveling
when it hits the ground?
Answer:
49m/s
59.07 m/s
Step-by-step explanation:
Given that :
Distance (s) = 178 m
Acceleration due to gravity (a) = g(downward) = 9.8m/s²
Velocity (V) after 5 seconds ;
The initial velocity (u) = 0
Using the relation :
v = u + at
Where ; t = Time = 5 seconds ; a = 9.8m/s²
v = 0 + 9.8(5)
v = 0 + 49
V = 49 m/s
Hence, velocity after 5 seconds = 49m/s
b) How fast is the ball traveling when it hits the ground?
V² = u² + 2as
Where s = height = 178m
V² = 0 + 2(9.8)(178)
V² = 0 + 3488.8
V² = 3488.8
V = √3488.8
V = 59.07 m/s

HELP NOW! A music club has 35 drum players. If 25% of the total number of members in the club are drum players, what is the total number of members in the club?
There's a way to think about it, in case you get other questions like this.
When you look at your problem, take out the 35. Out of the picture.
Look at 25%. 25% x 4 = 100% Meaning 4 is golden.
Then bring back the 35 and multiply it by 4. It gives you 140.

How are the signs of the coordinates of point A and point C related HURRY
Answer: They both are located at (2,3)
Step-by-step explanation:
The sign that A and C are related is that they both have the same distance from the y axis.
What are coordinates?a pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).
Coordinates are always written in the form of small brackets the first term will be x and the second term will be y.
For example (5,3) here 5 will be for the x and 3 will be for the y.
Another example is (9,0) here 9 is for x and 0 is for y.
Given that the coordinates A and C how are related now as we can see that both A and C are the same amount of distance by the y-axis.
This also can be seen by the coordination of A and C.

A radioactive substance decays according to the formula
Q(t)=Q0eâkt where Q(t) denotes the amount of the substance present at time t (measured in years),
Q0 denotes the amount of the substance present initially, and k (a positive constant) is the decay constant.
(a) Find the half-life of the substance in terms of k.
(b) Suppose a radioactive substance decays according to the formula
Q(t)=15eâ0.0001438t
How long will it take for the substance to decay to half the original amount? (Round your answer to the nearest whole number.) yr
Answer:
[tex]t=4820 y[/tex]
Step-by-step explanation:
a) The half-life equation is given by:
[tex]t_{1/2}=\frac{ln(2)}{k}[/tex]
b) Using the decay equation we have:
[tex]Q(t)=15e^{-0.0001438t}[/tex]
we need to find t when [tex]Q(t)=\frac{Q_{0}}{2}[/tex]
[tex]7.5=15e^{-0.0001438t}[/tex]
[tex]0.5=e^{-0.0001438t}[/tex]
[tex]ln(0.5)=-0.0001438t[/tex]
[tex]t=\frac{ln(0.5)}{-0.0001438}[/tex]
[tex]t=4820 y[/tex]
Therefore, it will take 4820 years to decay to half the original amount.

Triangle similarity problem
Answer:
ST = 16
Step-by-step explanation:
The similar triangles are given as triangle PQR similar to triangle STU.
That makes sides PQ and ST corresponding sides. It also makes sides PR and SU corresponding sides. The ratios of the lengths of corresponding sides of similar triangles are equal.
[tex] \dfrac{ST}{PQ} = \dfrac{SU}{PR} [/tex]
[tex] \dfrac{5x + 1}{36} = \dfrac{11x - 5}{63} [/tex]
Multiply both sides by 9.
[tex] \dfrac{5x + 1}{4} = \dfrac{11x - 5}{7} [/tex]
Cross multiply.
[tex] 7(5x + 1) = 4(11x - 5) [/tex]
Distribute on both sides.
35x + 7 = 44x - 20
Subtract 44x from both sides.
-9x + 7 = -20
Subtract 7 from both sides.
-9x = -27
Divide both sides by -9.
x = 3
ST = 5x + 1 = 5(3) + 1 = 15 + 1 = 16
Answer: ST = 16

John goes out to eat at a local restaurant. The bill comes to $47.83. John want to leave a 20% tip. How much of a tip should he leave? (use only numbers) $____
Answer:
Twenty percent of $47.83 is equal to $14.66
If you did 20% of 47.83, that would equal 9.566. So, now you need to take the 5, which is equal to 500 cents, and turn it into 5 dollars. (One hundred cents is a dollar so 500 cents , is 5 dollars.) now it’s 9 + 5. Easy, it’s 14. Now add back the 66, and it’s 14.66 dollars. So the answer is...
