Determine whether the function represents exponential growth, exponential decay, or neither. Explain.y = 161(0.725)t

SOVA2 [1]

If it looks like this
y = 161*(0.725)^t then it's a decay. Reason: the base is under 1. Try a couple of values for t say 0,1,2

y = 161 * (0.725)^0
y = 161

y = 161 * (0.725)^1
y = 161 * 0.725
y = 116.7

y = 161 * (0.725)^2
y = 161 * (0.5256
y = 84.63

You can see that the function is steadily getting smaller. Remember if the base is under 1 and more than 0 the function decays. If it is greater than 1 then the function grows.

Just to make sure we understand what I'm saying
0 < base < 1
y = a ( base)^power.

alisha [4.7K]

Answer:

20 km/h

Step-by-step explanation:

the total time is 0.5 hours as the cyclist travels for 30 minutes

the formula for speed is distance travelled divided by time taken which gives us 20 km/hr

joja [24]

Answer:

V=19.9*(0.9144m)^3=15,2146416738816 m^3

On their farm, Adam’s family maintains a storage that can hold 18.0 cubic yards (yd3) of grain. Use the fact that 1 yard is approximately equal to 0.9144 m to convert this volume to m3. Round your answer to the nearest hundredth. Do not type the units in the space below.

Step-by-step explanation:

1 yard =0.9144 m

We will take the 18.0 cubic yards, cross multiply with 0.9144 and then divide the result by one to get

A geometric sequence is defined by the equation an = (3)3 − n.

Delvig [45]

PART A

The geometric sequence is defined by the equation

$a_{n}=3^{3-n}$

To find the first three terms, we put n=1,2,3

When n=1,

$a_{1}=3^{3-1}$

$a_{1}=3^{2}$

$a_{1}=9$
When n=2,

$a_{2}=3^{3-2}$
$a_{2}=3^{1}$

$a_{2}=3$

When n=3

$a_{3}=3^{3-3}$

$a_{3}=3^{0}$
$a_{1}=1$
The first three terms are,

$9,3,1$

PART B

The common ratio can be found using any two consecutive terms.

The common ratio is given by,
$r= \frac{a_{2}}{a_{1}}$
$r = \frac{3}{9}$

$r = \frac{1}{3}$

PART C

To find
$a_{11}$

We substitute n=11 into the equation of the geometric sequence.

$a_{11} = {3}^{3 - 11}$

This implies that,

$a_{11} = {3}^{ - 8}$

$a_{11} = \frac{1}{ {3}^{8} }$

$a_{11}=\frac{1}{6561}$
