Answer:
20
Step-by-step explanation:
f(n)=n^2-n
f(-4)=(-4)^2-(-4)
f(-4)=16+4
f(-4)=20
The difference of a number and 5 = n - 5
Twice that = 2(n - 5)
‘is’ is the equal sign, so the expression before is equal to 7.
Equation: 2(n - 5) = 7
Answer:
1.2850
Step-by-step explanation:
Using the change of base formula,
Log 10 to base 6 = Log 10 ÷ Log 6
Log 10 = 1
Log 6 = 0.7782
Log 10 ÷ Log 6 = 1 ÷ 0.7782 = 1.2850
