Sydney placed 10 guppies in a fish tank she recorded the number of guppies in the tank
pav-90 [236]

Answer:

g(n) = 10 * 3^{n}

Step-by-step explanation:

Given

See attachment for table

Required

Determine the explicit formula for the table

First, we need to check if the guppies increases at arithmetic progression or geometry progression.

For arithmetic progression:

We calculate the common difference (d)

d = g(n) - g(n-1)

Take n as 1

d = g(1) - g(1-1)

d = g(1) - g(0)

From the table:

g(1) = 30\ \&\ g(0) = 10

d = 30 - 10

d = 20

Take n as 2

d = g(2) - g(1)

From the table:

g(1) = 30\ \&\ g(2) = 90

d = 90 - 30

d = 60

The two differences are not equal. So, this

For geometry progression:

We calculate the common ratio (r)

r = \frac{g(n)}{g(n-1)}

Take n as 1

r = \frac{g(1)}{g(1-1)}

r = \frac{g(1)}{g(0)}

From the table:

g(1) = 30\ \&\ g(0) = 10

r = \frac{30}{10}

r = 3

Take n as 2

r = \frac{g(2)}{g(1)}

From the table:

g(1) = 30\ \&\ g(2) = 90

r = \frac{90}{30}

r = 3

The two ratios are equal.

So, the next step is to calculate the explicit formula using n term of a geometric progression.

Because the progression starts from 0, we make use of the following formula

g(n) = g(0) * r^{n}

Substitute values for g(0) and r

g(n) = 10 * 3^{n}

Hence:

The explicit formula is: g(n) = 10 * 3^{n}

When using quadratics to model parabolic motion, which value represents the time at which the object falls to the ground? x-inte
morpeh [17]

Answer:  x-intercept

<u>Step-by-step explanation:</u>

NOTES

1) Parabolic motion is represented by the equation:

   h(t) = -9.8t² + vt + h   (in meters per second²), v is velocity

   or

   h(t) =  -32t² + vt + h   (in feet per second²),  v is velocity

2) The x-axis is time (in seconds) & the y-axis is height (in meters or feet).

Since you want to know what time the object hit the ground, h = 0

Therefore, you are looking for the zero of the equation, which is on the x-axis, thus is the x-intercept.
