Hey! So, here's a tip. When writing exponents, an easier way is to write a^b, rather than a to the b power. Besides that, here is your answer!
So-------
9^3=729
3^2=9
6^3=216
15^2=225
Now that we have that figured out, we can add them together, wish is simple. 729 + 9 + 216 + 225= 1,179.
Therefore, your final answer will be 1,174.
If you have any questions on this, I'm happy to help you. :)

Step-by-step explanation:
I really hope you know how to use your calculator to find regression equations, because in this forum it is impossible to teach you how to do that. I ran the data through my calculator and got the exponential equation as
which means at 4 hours, we started with 1963 bacteria and it is growing at a rate of 114% each hour. Since we started out with an x value of 0, and that value represents the number of bacteria after 4 hours, then time 0 is 4 hours, which means that time 12 is 16 hours. We replace the x in the equation with a 12 and do the math:
which gives us, in the end,
y = 9460
Answer:
7x^2 -28x +28
Step-by-step explanation:
7(x - 2)^2
7 ( x-2)(x-2)
Foil
7 ( x^2 -2x-2x+4)
Combine like terms
7( x^2 -4x+4)
Distribute
7x^2 -28x +28
Answer:
Step-by-step explanation
- Amount of discount: 20%= 0.20; 0.20×42= $8.4
- Sale price: $42-$8.4= $33.6
For interest question, plug in the values:
P= $3200
r= 3%÷100 = 0.03
t= 4 years
Calculate:
I=Prt
= 3200×0.03×4
=$384
