Answer:
$6752.86
Step-by-step explanation:
Given that the value of a car that costs $17900 depreciates at 13% per year, the value of the car in 7 years time will be:
The formula we will use is
V(t) = P(1 - r)^t
where P = 17900 r = 13% = 0.13 and t = 7
V(t) = 17,900 * (1 -0.13)^7
V(t) = $6752.86
Answer:
y - 8 = -2(x + 1)^2
Step-by-step explanation:
The vertex of this parabola is (-1, 8). It opens downward, so the x^2 term has a negative coefficient. The zeros are (-3, 0) and (1, 0), and the y-intercept is (0, 7).
Through the vertex form of the equation of a parabola we get:
y - (8) = a(x - (-1)) + 7, or
y - 8 = a(x + 1)^2. Find coefficient a by substituting the coordinates (-3, 0) in this equation:
0 - 8 = a(-3 + 1)^2, or
-8 = a(-2)^2, or a = -2
The desired equation is
y - 8 = -2(x + 1)^2
3 times 3 times 3 times 3 equals 81 so it would be 81
Discount is:
$42* (30/100)= $12.60
$42 -$12.60= $29.40
The sweater will cost $29.40 after the discount~
