Give more context please??
Answer:
Step-by-step explanation:
From the given information:
Let assume that the invested amount in the investment paying 8% interest is a
Now, since the total amount invested = $3000.
Then, the amount invested in the investment that will be paying 10% interest can be represented as:
= $(3000-a)
Income earned on $a that is being invested in 8% interest = $a × 8/100 = $0.08a
Income earned from $(3000-a) in the 10% investment is:
= $(3000-a)× 10/100
= $(300 - 0.1a)
Since total income of the two investment = $290;
Then;
0.08a + (300 - 0.1a) = 290
0.08a + 300 - 0.1a = 20-
300 - 0.02a = 290
-0.02a = -10
a = -10/-0.02
x = 500
Thus;
the amount invested in an investment paying 8% interest = $500
the amount invested in an investment paying 10% interest = $(3000 - 500) = $2500

Answer:
$3.07 in taxes
Step-by-step explanation:
You multiply 43.89 by .07 and the number you get is 3.07 and that represents the taxes. The total would be 46.96
Answer:
(2)
Step-by-step explanation:
2(2x-1) = 5x²
expand
4x - 2 = 5x²
subtract (4x-2) from both sides to make it a quadratic equation
5x² -4x + 2 = 0
plug into the quadratic formula
ax² + bx + c
thus, the coefficient attached to i is +- √6/5, making (2) our answer
(1) is not the answer because our answer would then be
a + bi = 2/5 + √6/5 * i * i = 2/5 - √6/5, which isn't our answer
