Answer:
31.5
Step-by-step explanation:
You need to first use the formula of calculating surface area of a cuboid
SA=2(lw+lh+wh)
now you put the values in as
H=3
W=1.5
L=2.5
You get 31.5
Hope this Helps!
Answer:
first one should be $35.52
Second one $18.60
Step-by-step explanation:
Answer:
the largest interval of x values where f(x) is increasing is (-1,1).
Step-by-step explanation:

the domain of f(x) is all real numbers.
As we can conclude from the table that the function f(x) is decreasing from (-3, -1) and the function is increasing from (-1, 1) .
Graphically we can also show this that for the x-values in (1,-1) function is increasing.
Answer:
y = 54 (⅓)ˣ
Step-by-step explanation:
Assuming this is an exponential function:
y = a (b)ˣ
Plug in both points:
54 = a (b)⁰
2 = a (b)³
First equation simplifies to a = 54.
Solving the second equation:
2 = 54 b³
1/27 = b³
b = 1/3
y = 54 (⅓)ˣ
18 is 60% of 30. I know this because 10% of 30 is 3 and 3 * 6 is 18
