Draw yourself a general representative triangle and label the base one of a triangle is increasing at a rate of 1,00 centimeters/minute while the area of the triangle is increasing at a rate of 1,000 square centimeters/minute. At a square centimeters? centimeters/minute and the altitude (height) another variable. Note that to solve this problem you don't need to know how big mor what shape the triangle really is. You have unlimited attempts remaining. - For login help or questions with the UCI WeBWorK system click here For instructions on how to enter answers in WeBWork click here fore ns Page generated at 8:21pm on Nov 26, 2015

Explanation / Answer

1) base = 19.6cm/minute

2) 169.19 nautical miles

3) A=8 B=5

4) Dy= 6x(x^2 + 3)

Dy = 1.2

5) x=-6

6) t1 = 0 and t2 =8/5

7) A=-7 , B=6

8) Minimum at x=8 and value= 259

Maximum at x=3 and value = 264

9)Minimum at x=-4 and value= -61

Maximum at x=0 and value = 3

10) -4/5

11) -6

x=1
