Answer:
Step-by-step explanation:
The standard form of this exponential function is
where a is the initial value and b is the growth rate. Our initial value is 490 and our growth rate is .2 so the equation is

I believe it’s b but maybe e or l for the answers to the questions
If we let x and y represent length and width, respectively, then we can write equations according to the problem statement.
.. x = y +2
.. xy = 3(2(x +y)) -1
This can be solved a variety of ways. I find a graphing calculator provides an easy solution: (x, y) = (13, 11).
The length of the rectangle is 13 inches.
The width of the rectangle is 11 inches.
______
Just so you're aware, the problem statement is nonsensical. You cannot compare perimeter (inches) to area (square inches). You can compare their numerical values, but the units are different, so there is no direct comparison.
Answer:
Degree 4
Step-by-step explanation:
Expression:
3x^3 + 3x^2y^2 - y^2
- 3x^3 - degree 3
- 3x^2y^2 - degree 2+2 = 4
- y^2 - degree 2
So the expression has degree 4 as per the highest degree of the terms
Answer:
You distribute the 2xy and get
2xy(3xy + 5y - xy^2) = 6(x^2)(y^2) + 10xy^2 - 2(x^2)(y^3)
