Answer:
its the second option...
Step-by-step explanation:
Answer:
Let's work out the intercepted points:
-4x + 8 = -3x^2 + 5x + 2
<=>
3x^2 - 9x + 6 = 0
<=>
x^2 - 3x + 2 = 0
<=>
(x - 1)(x - 2) = 0
<=>
x = 1 => y = -4 x 1 + 8 = 4 => A(1, 4)
and
x = 2=> y = -4 x 2 + 8 = 0 =>B(2, 0)
Then, length of chord AB is calculated by:
L = sqrt [(2 - 1)^2 + (0 - 4)^2)] = ~4.123
Answer:
30% profit
Step-by-step explanation:
The amount by which the shopkeeper reduced the advertised selling price = 20%
The resulting profit over the cost price = 4%
Let x represent the initial advertised selling price, and let y represent the new selling price, and let c represent the cost price, we have;
x - 20% of x = y
x - x × 20/100 = y
0.8·x = y
y = c + 4% of c = 1.04·c
∴ 0.8·x = 1.04·c
x = 1.04·c/0.8 = 1.3·c
x = 1.3·c = c + 0.3·c = c + 30% of c
x = c + 30% of c
From which we have that the initial advertised selling price, x = The cost price + 30% of the cost price
Therefore, the initial advertised selling price = The cost price + 30%profit on cost price.
The shopkeeper would have made 30% profit if the dress had then been sold at the original selling price.
