The student is right. Because when multiplying both numbers, we have to multipy the exponents together. And in this case we are going to get 8^-15. And when it is simplified, it is actually bigger than 1.
V=4/3*pi*r^3
dV/dr=4/3*pi*d(r^3)/dr =4/3*pi*(3*r^2)=4*pi*r^2
N³ - 2n² - 15n = 0
"n"
n (n² + 2n - 15) = 0
n = 0
n² + 2n - 15 = 0
Δ = (2)² - 4(1)(-15)
Δ = 4 + 60 = 64
n' = (-2+8) / 2 = 6/2 =3
n'' = (-2-8) / 2 = -10/2 = -5
Solution:
S {-5 , 0 , 3 }
Answer:
900
Step-by-step explanation:
its easy
It’s 37 4(2)+3(3)+20, 8+9+20,
17+20=37
