Ok so Candy draws a square design with a side length of x inches for the window at the pet shop. She takes the design to the printer and asks for a sign that has an area of
16x^2-40x+25square inches.
Let y(x) =16x^2-40x+25
If differentiating both sides w.r.t x we get
y'(x)=32x-40
And
to find critical point x ,Put y'(x)=0 then
32x-40=0
x=5/4
x^2 + 3x + 9
i hope that's what your looking for
she walked 12 and a half meter every day 12.5
Part/whole = percent/100
REMEBER THIS: 100 WILL ALWAYS BE THE TOTAL OF THE PERCENT!!!!!!!
So you multiply 24 ˣ 100 =2400/75 = 32
1g = 1,000mg
0.5g = 0.5 · 1,000mg = 500mg
