PSYCHO15rus [73]3 years ago
8 0

Answer:

Step-by-step explanation:

a =3 ;r  = 1/2

first term = 3

second term = 3*1/2 = 3/2

third term = 3/2 * 1/2 = 3/4

Fourth term = 3/4*1/2 = 3/8

Fifth term = 3/8 * 1/2 = 3/16

GP is: 3,3/2,3/4,3/8,3/16......

The quadratic function modeling the height of a ball over time is symmetric about the line , where t is time in seconds. Which s
Rashid [163]

Answer:

A. The height of the ball is the same after 1 second and 3 seconds.

Step-by-step explanation:

The quadratic equation function modeling is used to analyze the relationship between variables in the equation. If the ball is at height and t is time then the ball is on symmetric line which will move for initial 1 second then stabilizes at 3 seconds.

You toss a rock of mass m vertically upward. Air resistance can be neglected. The rock reaches a maximum height h above your han
laiz [17]

Answer:

v=\sqrt{\frac{3gh}{2}}

Step-by-step explanation:

If air resistance is neglected, the energy is constant. That means that in every point in the trajectory the energy is the same.

At the point of height h, all the energy is potential and velocity is zero (no kinetic energy)

E=mgh

At point of height h/4, some of the potential energy has transformed in kinetic energy and the velocity is no longer zero. But we know the total amount of energy is the same as the maximum height point.

With that information, we can calculate the velocity v:

E=mg(\frac{h}{4})+m\frac{v^2}{2}=mgh\\\\m\frac{v^2}{2}=mg(h-\frac{h}{4})\\\\\frac{v^2}{2}=\frac{3gh}{4}\\\\v^2=\frac{3gh}{2}\\\\v=\sqrt{\frac{3gh}{2}}

Given the following geometric sequence, find the common ratio:<br><br> {225, 45, 9...}
Tom [10]

Answer:

\frac{1}{5}  is the common ratio

Step-by-step explanation:

Common ratio(r) states that the ratio of each term of a geometric sequence to the term preceding it.

r = \frac{a_2}{a_1} =\frac{a_3}{a_2}........\frac{a_{n+1}}{a_n}

Given the sequence:

225, 45, 9, .........

Here,

a_1 = 225

a_2 = 45

a_3 = 9 and so on...

Using definition to find r.

r = \frac{45}{225}=\frac{9}{45}......

After solving we get;

r = \frac{1}{5}

Therefore, the common ratio is, \frac{1}{5}
