Answer:
212*(2)ⁿ
6784
Step-by-step explanation:
To find the number of two tailed monkey in 2016 we have
212*2
to find in 2017
212*2*2 or 212*2^2
we can write the following equation
212*(2)^n
where n is the number of years
To find the number of monkeys in 2020 we plug in 5 for n

Answer:
![(a)\ (8,-3)](https://tex.z-dn.net/?f=%28a%29%5C%20%288%2C-3%29)
Step-by-step explanation:
Given
![y =7x +-59](https://tex.z-dn.net/?f=y%20%3D7x%20%2B-59)
Required
Select all solutions
![(a)\ (8,-3)](https://tex.z-dn.net/?f=%28a%29%5C%20%288%2C-3%29)
This implies that:
![x = 8; y=-3](https://tex.z-dn.net/?f=x%20%3D%208%3B%20y%3D-3)
So:
![y =7x +-59](https://tex.z-dn.net/?f=y%20%3D7x%20%2B-59)
![-3 =7 * 8 + -59](https://tex.z-dn.net/?f=-3%20%3D7%20%2A%208%20%2B%20-59)
![-3 =7 * 8 -59](https://tex.z-dn.net/?f=-3%20%3D7%20%2A%208%20-59)
![-3 =56 -59](https://tex.z-dn.net/?f=-3%20%3D56%20-59)
![-3 =-3](https://tex.z-dn.net/?f=-3%20%3D-3)
The above is a solution:
![(b)\ (9,8)](https://tex.z-dn.net/?f=%28b%29%5C%20%289%2C8%29)
This implies that:
![x=9\ y =8](https://tex.z-dn.net/?f=x%3D9%5C%20y%20%3D8)
So:
![y =7x +-59](https://tex.z-dn.net/?f=y%20%3D7x%20%2B-59)
![8 =7 * 9 + -59](https://tex.z-dn.net/?f=8%20%3D7%20%2A%209%20%2B%20-59)
![8 =7 * 9 -59](https://tex.z-dn.net/?f=8%20%3D7%20%2A%209%20-59)
![8 =63 -59](https://tex.z-dn.net/?f=8%20%3D63%20-59)
![8 =4](https://tex.z-dn.net/?f=8%20%3D4)
The above is not a solution because ![8 \ne 4](https://tex.z-dn.net/?f=8%20%5Cne%204)
![(c)\ (7,-3)](https://tex.z-dn.net/?f=%28c%29%5C%20%287%2C-3%29)
This implies that:
![x=7;\ y=-3](https://tex.z-dn.net/?f=x%3D7%3B%5C%20y%3D-3)
So:
![y =7x +-59](https://tex.z-dn.net/?f=y%20%3D7x%20%2B-59)
![-3 = 7 * 7 +-59](https://tex.z-dn.net/?f=-3%20%3D%207%20%2A%207%20%2B-59)
![-3 = 7 * 7 -59](https://tex.z-dn.net/?f=-3%20%3D%207%20%2A%207%20-59)
![-3 = 49 -59](https://tex.z-dn.net/?f=-3%20%3D%2049%20-59)
![-3 = -10](https://tex.z-dn.net/?f=-3%20%3D%20-10)
The above is not a solution because ![-3\ne -10](https://tex.z-dn.net/?f=-3%5Cne%20-10)
![(d)\ (10,5)](https://tex.z-dn.net/?f=%28d%29%5C%20%2810%2C5%29)
This implies that:
![x =10; y=5](https://tex.z-dn.net/?f=x%20%3D10%3B%20y%3D5)
So:
![y =7x +-59](https://tex.z-dn.net/?f=y%20%3D7x%20%2B-59)
![5 = 7 * 10 + -59](https://tex.z-dn.net/?f=5%20%3D%207%20%2A%2010%20%2B%20-59)
![5 = 7 * 10 -59](https://tex.z-dn.net/?f=5%20%3D%207%20%2A%2010%20-59)
![5 = 70 -59](https://tex.z-dn.net/?f=5%20%3D%2070%20-59)
![5 = 11](https://tex.z-dn.net/?f=5%20%3D%2011)
The above is not a solution because ![5 \ne 11](https://tex.z-dn.net/?f=5%20%5Cne%2011)

Answer:
the conclusion is not justified. No statement is made regarding the angles of the rhombus
Step-by-step explanation:
A square is a rectangle because of its right angles, not because of its equal-length sides. The rhombus having equal-length sides does not qualify it as a rectangle. The conclusion of the argument is unsupported.
8.8 because you need to multiply 1.68 by 10 which is 16.8-8=8.8
