Your Answer Is 4
f(x) = x⁷ – 6x⁶ + 8x⁵
f'(x) = 7x⁶ - 36x⁵ + 40x⁴
= x⁴ (7x² - 36x + 40) ... (1)
Critical point (x,y): x = 0 , x = (36 ± √(-36)²-4*7*40) / (2*7) = (18±2√11) / 7
x = 0 or x = 3.5 or x = 1.6
plug into (1): y = 0 , y = -394.3 , y = 10.1
extreme : maximum (1.6 , 10.1) minimum (3.5 , -394.3) ... turning points
x⁷ – 6x⁶ + 8x⁵ = x⁵ (x² - 6x + 8) = x⁵ (x-2) (x-4) =0
real zeros: x = 0, x=2, x=4
Answer:
C = 2½ miles.
Step-by-step explanation:
Let the total distance be A
Let the distance covered be B.
Let the unknown distance (distance left) be C.
<u>Given the following data;</u>
A = 3¾ miles
B = 1¼ miles
To find the distance left to hike;
A = B + C
Substituting into the equation, we have;
3¾ = 1¼ + C
C = 3¾ - 1¼
C = (3 - 1) ¾ - ¼
C = 2 2/4
<em>C = 2½ miles. </em>
<u>Method II.</u>
We would convert the mixed fraction into a proper fraction:
A = 3¾ = (4*3 + 3)/4 = 15/4
B = 1¼ = (4*1 + 1)/4 = 5/4
C = 15/4 - 5/4
C = 10/4
C = 5/2
<em>C = 2½ miles. </em>
