Answer: 11 square root 57
Step-by-step explanation:
<h3>
Answer: Yes they are equivalent</h3>
==============================================
Work Shown:
Expand out the first expression to get
(a-3)(2a^2 + 3a + 3)
a(2a^2 + 3a + 3) - 3(2a^2 + 3a + 3)
2a^3 + 3a^2 + 3a - 6a^2 - 9a - 9
2a^3 + (3a^2-6a^2) + (3a-9a) - 9
2a^3 - 3a^2 - 6a - 9
Divide every term by 2 so we can pull out a 2 through the distributive property
2a^3 - 3a^2 - 6a - 9 = 2(a^3 - 1.5a^2 - 3a - 4.5)
This shows that (a-3)(2a^2 + 3a + 3) is equivalent to 2(a^3 - 1.5a^2 - 3a - 4.5)

Answer:
The answer is (d)
Exponential decay function

Step-by-step explanation:
∵ y = 0.8^x
∵ 0.8 < 1
∴ 0.8^x is decreasing ⇒ exponential decay function
Ex: 0.8^-4 = 2.441 ⇒ 0.8^4 = 0.4096
when x increase the value of 0.8^x decrease

∴ The answer is (d)
Follow the formula Interest=(Principal)(Rate)(Time)
So, the equation would be:
I= 10,000x0.09x5
This equals $4,500
So, the amount of interest is $4,500
