The answer would be: D. f(x)=2x
The f-1(x) is also called as an inverse function. To find the inverse function, you just need to switch the y variable with the x variable. The inverse function of f(x)=2x would be
y=2x
x'=2y'
y'= 1/2 x'
The inverse function is different with f(x)
Answer:
1. 2.19g + 0.59b + 1.49p
2. 6.57 + 1.77 + 2.98 = 11.32
Answer:
Lateral areas have ratio of 4:1
Volumes have ratio of 8:1
Step-by-step explanation:
There is a rule in 3D geometry that when two solids are similar, and their edges are in the ratio of 
, the ratio of any surface area type measure is always 
this includes the lateral area, which is just a surface area minus the base, which is not important for this problem. The ratio of volumes of those similar solids is in the ratio of 
.
Now, to solve this, we need to find the ratio of any corresponding length of these similar pyramids. We have both the heights, so if we form a ratio of 
which if you simplify it, it is 
, which is 
. The ratio of the heights are 
.
Now we can apply those rules to this ratio, the ratio of lateral areas would then be 
, which is 
. the ratio of volumes would be 
, which is 
Carlos rode an average of 9 miles every hour on his bicycle. It is because 3*9=27 and the distance is rate multiplied by time. use the formula and check it!
Hope I helped.
Good Luck!
