Answer:
$72
Step-by-step explanation:
100 - 10% = 90
90 - 20% = 72
(x-h)^2=4p(y-k)
vertex is (h,k)
p is the distance from focus to vertex and distance from vertex to directix (vertex is in middle of directix and focus)
if p is positive, the parabola opens up and the focus is above the directix
if p is negative, the parabola opens down and the focus is below the directix
we see the directix is over the focus (1>-1) so the parabola opens down and p is negative
distance from (5,-1) to y=1 is 2 units
2/2=1
p=-1 since p is negative
1 up from (5,-1) is (5,0)
veretx is (5,0)
(x-5)^2=4(-1)(y-0)
(x-5)^2=-4y is the equation
Answer: use PEMDAS
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Y is the starting point so it would be y=12322 and it becomes 1.18 because you add 100 to 18
Since 5×4 is in brackets, we start with that
so 2÷3 (20)÷3+6÷7
we do ×/÷ first from the left
so 4.44+ 0.8571428571 = 5.301
