A: -3.25 or -13/4,b:-13/4?????
6+6=12 + 6= 18
6x3=18
(I feel like u know the answer, just asking to give away free points. Either way the answer is 18 and thank you.)
Answer:
the answer is 155 and 93
Step-by-step explanation:
5 and 3 are 8, divided 248 by 8 u get 31. multiply 5 and 31= 155, multiply 3 and 31= 93. 155+91=248
Answer: false
Step-by-step explanation:
If f and g are increasing on I, this implies that f' > 0 on I and g' > 0 on I. That is both f' and g' have a positive slope. However,
Using product rule;
(fg)' = fd(g) + gd(f)
(fg)' = f * g' + f' * g
and although it is given that g' and f' are both positive we don't have any information about the sign of the values of the functions themselves(f and g). Therefore, if at least one of the functions has negative values there is the possibility that the derivative of the product will be negative. For example;
f = x, g = 5x on I = (-5, -2)
f' = 1 and g' =5 both greater than 0
f and g are both lines with positive slopes therefore they are increasing, but f * g = 5x^2 is decreasing on I.
It has to be b because none of the others are correct.
