Answer:
x=3 15/16 hours together
Step-by-step explanation:
the painter paints 1/7 of the house in 1 hour
the assistant paints 1/9 of the house in 1 hour
x=# of hours it takes them together to paint the house
(1/7)x+(1/9)x=1 (job finished)
multiply both sides by the LCM which is 63
63(1/7)x+63(1/9)x=63(1)
9x+7x=63
16x=63
x=63/16
x=3 15/16 hours together
Answer:The missing number is 27
Step-by-step explanation:It is a matter of spotting the relationship if you can. If not obvious you will need to experiment to find what type of sequence it is; geometric or arithmetic.
Observe that there is a connection of 3 in the numbers 1,3,9 in that
1
×
3
=
3
Lets experiment with that for a moment!
If we apply the same rule to 3 what will we get?
3
×
3
=
9
which is correct.
Ok. lets apply the same rule yet again!
9
×
3
=
27
Using 27, if we apply the rule once more and get 81 we have found the correct 'rule' for this sequence.
27
×
3
=
81
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This works so the missing number is 27
Question #1 is x=-44
Question #2 is both points are a local minimum
Question #3 is g''=(x^2-4x+16)/(x-2)^2 since g'' is never negative, g is never concave down
Question #4 is y-4=-9(x-3)
Question #5 is since the graph is always concave up, any tangent lines muse lie below the graph.
I hope that helped
