<u>Answer:</u>
![y = 2 5 0 ( 0 . 8 9 ) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%202%205%200%20%28%200%20.%208%209%20%29%20%5E%20x%20)
Initial value: 250
Decay
Decay rate: 11%
![y = 4 0 ( 1.11 ) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%204%200%20%28%201.11%20%29%20%5E%20x%20)
Initial value: 40
Growth
Growth rate: 11%
<u>Step-by-step explanation:</u>
The function we have on the left of the table is:
![y = 2 5 0 ( 0 . 8 9 ) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%202%205%200%20%28%200%20.%208%209%20%29%20%5E%20x%20)
<u>Initial value</u> (when x = 0): ![y = 2 5 0 ( 0 . 8 9 ) ^ 0](https://tex.z-dn.net/?f=%20y%20%3D%202%205%200%20%28%200%20.%208%209%20%29%20%5E%200%20)
y = 250 (initial value)
Growth or Decay: 0.89 < 1 so decay
Decay rate: (1 - 0.89) * 100 = 11%
Function on right side:
![y = 4 0 ( 1.11 ) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%204%200%20%28%201.11%20%29%20%5E%20x%20)
<u>Initial value</u> (when x = 0): ![y = 4 0 ( 1 . 1 1 ) ^ 0](https://tex.z-dn.net/?f=%20y%20%3D%204%200%20%28%201%20.%201%201%20%29%20%5E%200%20)
y = 40 (initial value)
Growth or decay: 1.11 > 1 so growth
Growth rate: (1.11 - 1) * 100 = 11%
Answer:
$400
Step-by-step explanation:
Let 'p' represent the original price, the 'p-0.3p' represents the sale price:
280 = p - 0.3p
.
Solving for 'p' we have p=400.
The original price of the television was $400
It would be B because you would take amelias age and take two away since todd is five years younger to get the a-5.
hope this helps :)
Answer:
The answer should be 69°
Step-by-step explanation:
Each line is being cut by a transversal, that means that the degree on the other side of it, added with the given degree will add up to 180°
1. On the right, you need to find the interior angle where 160° is outside so you subtract 180° from 160° to find the angle inside. That gives you 20°
2. On the top left you have 131° so 180°-131°=49°
Next you add the angles you have and then subtract it from 180 to get the interior angle with n° outside.
3. 20°+49°=69°
4. 180°-69°=111°
Then you do the same thing as the beginning which would be n°+111°=180°
5. n°+111°=180°, that means n=69°
Hopefully that clears it up for you :)
