I think it's 27 minutes
Step-by-step explanation:
D and e are equivalent
if you plug in 1,2,3 for X for each equation you can see only d and e are equivalent to the original this is because (50/5)^x and 50^x/5^x simplified is still 10^x
Answer:
Step-by-step explanation:
This is not possible over the real numbers system. You cannot take the square root of a negative number without ending up with imaginary solutions.
and
In the world of imaginary numbers, the 2 solutions would be
x = 5i and x = -5i
0.5 repeating as a fraction can be written as 5/9
Answer:
Yes
Step-by-step explanation:
f(x) = x³ − 9x² + 11x + 21
f(3) = (3)³ − 9(3)² + 11(3) + 21
f(3) = 27 − 81 + 33 + 21
f(3) = 0
