A=w*h
p=2w+2h
if w=x, then h=7-x.
a(x) = x*(7-x)
a(x) = 7x - x^2
to find the largest area we need to derivative a(x):
a'(x) = 7 - 2x = 0 --> x = 3.5
therefore:
maxArea = a(3.5) = 3.5 * 3.5 = 12.25
2.37t = feet, where t is time, in minutes. for 6 minutes we do 2.37(6) = 14.22 feet
1/2 × 40 = 2x + 8
⇔ 20 = 2x + 8
⇔ 12 = 2x
⇔ x = 6
Answer:
a) buffalo will be at 7
b) it will be -8
Step-by-step explanation:
a) because if u add - 3 + 10 it will equal 7
b) reason why is because if u substract -24 from - 16 it will be - 8
I took a test on the same thing thats why i kno it
Answer:
14
