You have to put the number in the graph
The expansion of a perfect square is
In words, the square of a sum of two terms is the sum of the squares of the two terms ( and ), plus twice the product of the two terms ()
So, when determining if you have a perfect square trinomial, you should have two perfect squares. Note that they don't have to be the first and third term, since you can rearrange terms as you prefer.
<u>Explanation:</u>
The rate is 8. It's attached to the "x". When graphed, 8 is the slope.
The y-intercept represents the initial value, or the starting amount of money in Rose's bank account.
Answer:
40,000
Step-by-step explanation:
You want to start with the exponent and then multiply afterward in both of the equations.
8 x 10^-2:
10^-2 = 0.01
0.01 x 8 = 0.08
2 x 10^-6:
10^-6 = 0.000001
0.000001 x 2 = 0.000002
Obviously, you can see the relationship between 8 and 2 in the division. Now, you just divide 0.08 by 0.000002 and you get 40,000.
Sqrt(49)*sqrt (-1) -4 = 7i-4
