Volume = are base*height
32 = x^2*h --> h = 32/x^2
surface area = 4x(32/x^2) + x^2
SA = 128/x + x^2
SA' = -128/x^2 + 2x = 0
2x = 128/x^2
2x^3 = 128
x^3 = 64
x = 4
surface area minimized when length of base is 4 in.
hope this help
FALSE.
The effect of adding +3 to the argument of a function f(x) is to shift the original f(x) horizoantally 3 units to the left.
Answer:
3 ways
Step-by-step explanation:
7 and 3
6 and 4
5 and 5
you need to get a common denominator
the common denominator is 40
3/8 * 5/5 = 15/40
2/5 * 8/8 = 16/40
25 15/40 < 25 16/40 so Karen rode farther
