Answer:
Option D.
Step-by-step explanation:
To find the inversion of a function follow the following procedure
1) Replace x with y in the function and clear y
------> 


2) Check. The range of f(x) is the domain of
.
So if f(a) = b, this means that
= a.


Is fulfilled. Therefore
is the inverse of 
Answer:
For an equation like:
y = a*x + b
a is the slope, and this is the rate of change of the function.
For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.
Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.
No. For example, if I gave you the equation y= 3x+5, the y-intercept will be at (0,5), eliminating the (0,0).
Answer:
true
Step-by-step explanation:
If the total unit cost of manufacturing Product Y is currently $40 and the total unit cost after modifying the style is estimated to be $48, the differential cost for this situation is $8.
true
Answer:
Surface area of box = 94cm²
Step-by-step explanation:
Given that:
Width of box = 3 cm
Length of box = 5 cm
Height of box = 4 cm
Surface Area = 2lw + 2lh + 2hw
Surface area = 2( lw + lh + hw )
Surface area = 2(5*3 + 5*4 + 4*3) = 2(15+20+12)
Surface area = 2(47) = 94 cm²
Hence,
Surface area of box = 94cm²
