Step-by-step explanation:
75×12 , 75× 6(year and A HALF) + 400
If there is 4 thousands and 7 hundreds is 4,700
Answer:
Step-by-step explanation:
the first method :
s(x) = 2 - x and f(x) = 3x
(s f) (-7) = s(-7) ×f(-7)
but : s(-7) = 2 - (-7) =2+7 = 9
f(-7) = 3(-7) = - 21
so : (s f) (-7) = (9)×(-21) = - 189
the second method :
calculate : (s f) (x) == s(x)×f(x) = (2-x) 3x = 6x - 3x²
(s f) (-7) = 6(-7) -3 (-7)² = - 42 -147 = -189
The answer would be An = -1.3n + -3.7
Drops = 27
First, we need to find the volume of the given tank using the following equation

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation
