Answer: 50
Step-by-step explanation:
I am rounding it to 1 significant figure.
9.8 = 10 (round up when the last digit is 5, 6, 7, 8 or 9)
5.2 = 5 (round down when the last digit end with 0, 2, 3 or 4)
So it now is 10 x 5 = 50
A.) A = P (1 + r)^t
P = 500 ; r = 3% ; t = 2
A = 500 (1 + 0.03)²
A = 500 (1.03)²
A = 500 * 1.0609 numerical expression
A = 530.45
A numerical expression is an expression that involves purely numbers and one or more operational symbols.
B) compound interest for 2 years.
530.45 - 500 = 30.45 is the compound interest for 2 years.
Answer:
in order from least to greatest:
-1.6, -1.4, -0.9, 0.25, 0.6
Step-by-step explanation:
Convert each numeral into its mixed number decimal fraction equivalent:
-1.4 = -1.4
-8/5 = -1.6
0.6 = 0.6
-0.9 = -0.9
1/4 = 0.25
Now arrange these in order from least to greatest:
-1.6, -1.4, -0.9, 0.25, 0.6
Answer:
The negative three times negative five
Answer:
Step-by-step explanation:
Take out the common factor from the first and second terms and again from the 3rd and fourth terms.
x^2(x + 2) - 9(x + 2)
Take out x + 2 from around the minus sign.
(x + 2)(x^2 - 9)
Factor x^2 - 9 which will come out to the difference of squares.
(x + 2)(x + 3)(x - 3)
This is how it factors.
You could also use synthetic division if you know how it works.
-2 || 1 2 -9 -18
-2 0 18
====================
1 0 -9 0
This gives you (x + 2)(x^3 - 9) just as before.
