32
Step-by-step explanation:
you listed 8 animals and each of those species have 4 legs
Answer:
20
Step-by-step explanation:
substitute first to get:
6 + (3·4 - 5)2
multiply 3 and 4 to get 12:
6 + (12 - 5)2
subtract 12 and 5 to get 7:
6 + 7(2)
multiply 7 and 2 to get 14
6 + 14 = 20
First, we would need to divide the number of portraits he can paint (919,191) by the amount of weeks it takes (777), which gives us 1,183 portraits per week. Then, we have to multiply that number by 444, which gives us 525,252, which is our answer to this problem. So Luke can paint 525,252 portraits in 444 weeks.
Answer:
a. 28.
b 20.78.
Step-by-step explanation:
a. f(x) = 0.001(x - 10)(x + 20)(x - 40)
When x = 50
Height = f(40) = 0.001(50-10)(50+20)(50-40)
= 0.001(40*70*10)
= 0.001 * 28,000
= 28 units.
b.
Expanding the function we get
f(x) = 0.001(x - 10)(x^2 - 20x - 800)
f(x) = 0.001(x^3 - 30x^2 - 600x + 8000)
f(x) = 0.001x^3 - 0.03x^2 - 0.6x + 8
Finding the derivative
f'(x) = 0.003x^2 - 0.06x - 0.6
This is zero for maxm/minm values:
0.003x^2 - 0.06x - 0.6 = 0
x = 27.32, - 7.32.
The values of the heights corresponding to these values of x are:
0.001(27.32-10)(27.32+20)(27.32-40)
= -10.39. and
0.001(-7.32-10)(-7.32+20)(-7.32-40)
= 10.39.
So the distance between A and B = 10.39 - (-10.39)
= 20.78.
