Answer:
f^(-1)(x) = (x-b)/m or x/m - b/m
Step-by-step explanation:
f(x) = y = mx + b
To find the inverse function, interchange x and y and solve for y, i.e.
x = my + b
my = x-b
y = (x-b)/m = x/m - b/m
Answer:
6/5 or 1 1/5
Step-by-step explanation:
Each piece is 2/5 so you add it up 3 times or multiply by 3 to get 6/5 or 1 and 1/5.
Answer:
77 C
Step-by-step explanation:
To find the mean add all the numbers together then divide by the total amount of numbers
The volume of a cone is V=(1/3)(area of the base)(height)= (1/3)(pi*r^2)(h)
r^2= (d/2)^2 = (d^2)/4. Given: V= 301.44cm^3 and h= 18cm.
r^2= V/[(1/3)(pi)(h)]
r^2= 3V/(pi)(h)
(d^2)/4= 3(301.44)/(3.14)(18)
d^2= 12(301.44)/(3.14)(18)
d^2= 63.967
d= 7.997
d~= 8cm.
Answer:42
Step-by-step explanation:
V= 18 + 6(4)
V= 18 + 24
V= 42
