Answer:
a 840$
Step-by-step explanation:
bcuz
marked price = $1200
discount % = 30%
selling price = ?
so,
SP = MP - D% of MP
= $1200 - 30% × 1200
= $1200 - 360
= $840
The range is the highest y value to the lowest y value
ok
find the vertex because it is the highest or lowest point in the equation
make into f(t)=a(x-h)²+k form
(h,k) is the vertex
k is the y value of the vertex
if a>0, then the vertex is the minimum
if a<0, then the vertex is the maximum
so
f(t)=t²-6t
f(t)=t²-6t+9-9
f(t)=(t-3)²-9
f(t)=1(t-3)-9
k=-9
a=1
1>0
so y=-9 is the minimum value
the maximum value will be infinity
so the range is from y=-9 to infintiy
so R=[9,∞)
Answer:
(x-3)^2 + (y+1)^2 =65
Step-by-step explanation:
1.find centre
2. substitute centre (h,k) into (x-h)^2 + (y-k)^2 = r^2
Answer:
Step-by-step explanation:
24:
1 and 24
6 and 4
2 and 3 2 and 2
So 24 = 1 X 2^3 X 3
28:
1 and 28
7 and 4
2 and 2
So 28 = 1 X 2^2 X 7
Therefore the greatest common factor of 24 and 28 is 2.
