Answer:
Rs. 300
Step-by-step explanation:
Given that the watch was sold for 90%.
So, 90% = 270.
We have to find 100%.
To do this, find ten % the. Multiply that by 10.
90%=270
10% = 270/9 = 30
100% = 30 x 10= 300.
Hope this helps
= 3(4a^2 + 4a - 3) - 4a^2 + 28
= 12a^2 + 12a - 9 - 4a^2 + 28
= 8a^2 + 12a + 19
= 4a(2a + 3) + 19
For vertex at (h,k)
the equation is
y=a(x-h)^2+k
for vertex at (0,-1)
equation is
y=a(x-0)^2+(-1) or
y=ax^2-1
find what a is
(2,2)
x=2
y=2
2=a(2^2)-1
2=a(4)-1
add 1
3=a(4)
divide both sides by 4
3/4=a
the equation is
y=3/4x^2-1
