Amount in compound interest = p(1 + r/t)^nt where p is the initial
deposit, r = rate, t = number of compunding in a period and n = period.
Here,
Amount after 4 years = 500(1 + (2/100)/3)^(4 x 3) = 500(1 +
0.02/3)^12 = 500(1 + 0.0067)^12 = 500(1.0067)^12 = 500(1.083000) =
$541.50

Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
Answer:
a mix with a total cost of x=$73.
Of course, 30 pounds (50 pounds - 20 pounds = 30 pounds) of that mix will be the more expensive ground beef.
Answer:
-13=5+x, rearrange the terms.
-x=5+13, add.
-x=18, invert the sign.
x=-18
