The best one that is described is the first one
The example of exponential growth is: <span>c. y=0.5(1.5)x </span>
The function y = ab˟ is a can only be growth function if the value b>1. And if 0<b<1 it will decay. Therefore, the only correct value that fits the definition of exponential growth is option C.
Answer:
(0.9,4.2)
Step-by-step explanation:
Given:
The table above such that
![y = -x + 5](https://tex.z-dn.net/?f=y%20%3D%20-x%20%2B%205)
![y = 6x - 1](https://tex.z-dn.net/?f=y%20%3D%206x%20-%201)
Required
Approximation of the solution
To do this, we start by equating both values of y
![-x + 5 = 6x - 1](https://tex.z-dn.net/?f=-x%20%2B%205%20%3D%206x%20-%201)
Collect like terms
![-x - 6x = -5 -1](https://tex.z-dn.net/?f=-x%20-%206x%20%3D%20-5%20-1)
![-7x = -6](https://tex.z-dn.net/?f=-7x%20%3D%20-6)
Divide both sides by -7
![\frac{-7x}{-7} = \frac{-6}{=7}](https://tex.z-dn.net/?f=%5Cfrac%7B-7x%7D%7B-7%7D%20%3D%20%5Cfrac%7B-6%7D%7B%3D7%7D)
![x = \frac{6}{7}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B6%7D%7B7%7D)
![x = 0.8571](https://tex.z-dn.net/?f=x%20%3D%200.8571)
(Approximated)
Substitute
for x in any of the expression of y
Using ![y = -x + 5](https://tex.z-dn.net/?f=y%20%3D%20-x%20%2B%205)
![y = -\frac{6}{7}+ 5](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B6%7D%7B7%7D%2B%205)
![y = \frac{-6+35}{7}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-6%2B35%7D%7B7%7D)
![y = \frac{29}{7}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B29%7D%7B7%7D)
(Approximated)
The closest to this is option D
(x,y) = (0.9,4.2)
Answer:
Is an irrational number because it cannot be turned into a fraction or have any specific patterns. An irrational number is an number that is not a terminating or repeating decimal, and that applies to
. So therefore,
Is an irrational number.
