Answer:
31 i think
155.3 divided by 5 is equal to 31
C = (5n + 40)/9
Multiply by 9 on both sides
9C = 5n + 40
Subtract 40 from both sides
9c - 40 = 5n
Divide both sides by 5
9c/5 - 40/5 = n
n = (9/5)c - 8
Answer:
AC or Alternating current electricity
Step-by-step explanation:
Answer:
Step-by-step explanation:
f(x) = - 4√x
1) the domain : x ≥ 0 : D= [0;+∞[
2) the rang of : f is the domain of the inverse
y = -4 √x calculate x ..... ( x ≥ 0)
y ≥ 0 : y² = ( -4 √x )²
y² = 16 x
x = y²/16
the inverse is : g(x) = x²/ 16 .... x ≥ 0 the range is : D= [0;+∞[ ( same domain)
