Answer:
number 3
Step-by-step explanation:
Answer:
4a) 4 1/6
4b) 2
5a) 36.424
5b) 5.4
Step-by-step explanation:
When multiplying or dividing by mixed numbers, convert them into improper and just do it from left to right for each numerator and denominator
First convert the feet to inches:
3 feet= 36 in.; 4 feet=48 in.
Make an equation for each one:
Type A: h=36+15x
Type B: h=48+10x
Since the questions wants the heights to be equal, h=h so you can substitute so you have:
36+15x=48+10x
5x=12
x=2 2/5 years or 2.4 years
True. Every irrational number is included in the set of real numbers.
The irrational numbers are a subset of the real numbers.
The Lagrangian is

with critical points where the partial derivatives vanish:





The second and third equations tell us
, so that in the last equation we find

and from the fourth equation we get

So we have two critical points,
and
, which give respective extreme values of
(maximum) and
(minimum).
