Possible derivation:
d/da(4 - 8 a)
Differentiate the sum term by term and factor out constants:
= d/da(4) - 8 (d/da(a))
The derivative of 4 is zero:
= -8 (d/da(a)) + 0
Simplify the expression:
= -8 (d/da(a))
The derivative of a is 1:
= -8 1
Simplify the expression:
Answer: = -8
Answer:
16/81
Step-by-step explanation:
(-2/3)^4
expand...
-2/3*-2/3*-2/3*-2/3
multiply
numerator: -2*-2*-2*-2=16
denominator: 3*3*3*3=81
Thus the fraction is 16/81
Hope this helps!!!
Let x=number 1 let y=number2
there sum is equal to 70
then
number1+number2=70
substituting
x+y=70
y=70-x
let there product will be p
p=xy
substituting
p=x(70-x)
which is choice c
