L = $20 r = 4% t = 2 years
Annette [7]
I'm guessing this is a question about interest rates? If you have $20 that increases by 4% in one year, you need to multiply 20 by 1.04. This gets you $20.8.

If you are talking about compound interest, we will take this number and multiply it again by 1.04 for the second year. 20.8 x 1.04 = $21.632. 

If it is instead simple interest, we will simply add another .8 dollars for each year, instead of getting 4% interest compounded every year onto the new value. This gets you $21.6.

What is the sum of 4.9 × 102 and 6.8 × 103?
dusya [7]

Answer:

The sum is

7.92\times 10^3

Step-by-step explanation:

We want to add

4.9\times 10^2 and 6.8\times 10^3

The sum of these two numbers is:

4.9\times 10^2 +6.8\times 10^3

This is the same as:

4.9\times 100 +6.8\times 1000

490 +6800=7290

We rewrite 7290 in standard form to get;

7.92\times 10^3

Hello may i please have help with this question
Pani-rosa [81]

Answer:

x=√139-3, x=-√139-3

Step-by-step explanation:

to complete the square, you first move the constant to the other side of the equation-its already done for you!

now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.

What you do to one side has to be done with the other.

x^2+6x+9=130+9

now you can factor the square:

(x+3)^2=139

squareroot both sides:

x+3=√139

x+3=-√139

now subtract both sides by 3

x=√139-3

x=-√139-3
