Answer:
(n^4 + ((-1)^n)*n^2) / ((-n)^5 + 3(n^3))
n^4 + -1/ -1^5 + 3n^3
n^4 + -1^n / -1^5 +3^3
n^4/ -1 + 3n^3
n^4/ -1 + 3x1^3
n/-1 + 3n
1/-1+3
n = 2
Answer:
c ≈ 40
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° =
=
=
( multiply both sides by c )
c × sin40° = 26 ( divide both sides by sin40° )
c =
≈ 40 ( to the nearest whole number )
Simply follow the units into quantities
E/(mT) = c
Where
E = energy
m = mass
T = temperature
c = specific heat
Solving for T
358/(15*T) = 0.385
T = 62°C
v is 4 more tha x
v=4+x
sum is no more than 14
v+x≤14
sub 4+x for v
4+x+x≤14
4+2x≤14
minus 4 both sides
2x≤10
divide both sides by 2
x≤5
5+4=9
the neighboor's age is 5 years
and victoria is 9
we need the previous question
