A suitable calculator finds the determinant to be ...
... B. -203
_____
This can be calculated by hand by copying the first two columns to the right of the given matrix, then forming the sum of products of the downward diagonals and subtracting the sum of products of the upward diagonals.
... (-4)(3)(-5) +(-4)(-5)(-5) +(-3)(3)(2) -(-5)(3)(-3) -(2)(-5)(-4) -(-5)(3)(-4)
... = 60 -100 -18 -45 -40 -60
... = -203
2 and 5/4 (if you mean fraction greater than 1)
or
3 and 1/4
Happy to Help!
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
So you could do $1725/3 (divided by) which would give you 575 then mulitply that by two and that will give you the months rent of, $1,150. I hope this helps!
Answer:
slope is 1
Step-by-step explanation:
y = mx + b
the m is 1 in this case.
m is the slope
b is the y- intercept
