Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -4x² + 6x - 4
f(5) is x = 5
<u>Step 2: Evaluate</u>
- Substitute: f(5) = -4(5)² + 6(5) - 4
- Exponents: f(5) = -4(25) + 6(5) - 4
- Multiply: f(5) = -100 + 30 - 4
- Add: f(5) = -70 - 4
- Subtract: f(5) = -74
We solved it using the rule:

Answer:
1/27 cubic in.
Step-by-step explanation:
1/3*1/3*1/3= 1/27
As you know what 100% is (810) the best thing to do is to find what 30% is.
The best way to do this is to find 10% then multiply it by 3.
810/10= 81
81*3= 243
You've then got to add these two (810 and 243) together
810+243= 1053
As you've got an increase, this then means that you have to add this to the original number
810+1053= 1863
Therefore, there are now 1863 songs.
Hope this helps :)
