Answer:
Inverse function is
.
Step-by-step explanation:
Given function is
.
Now we need to find the inverse of the given function.
Step 1: replace f(x) with y

Step 2: switch x and y

Step 3: solve for y




Hence required inverse function is
.
Answer:
the possible answer would be A, 6.
Step-by-step explanation:
6/2 is equal to 3 wholes. 7 minus 3 is 4. the sign > is used to indicate that the left number is greater than the right number, which is 3. 4 > 3 would be shown. this means that 6, or A, is the answer! :)
(6 IS ALSO THE ONLY OPTION. I NOTICED IT SAYS “ALL ANSWERS“
3(j+4)-9=9
3j + 12 -9 =9
3j +3 =9
3j =6
j=2
Let the height of the building be x. Let the initial distance of the ant from the building be y, then
tan 32 = x/y
y = x/tan 32 . . . . . . . . (1)
tan 22 = x/(y + 66)
y tan 22 + 66 tan 22 = x
y = (x - 66 tan 22)/tan 22 . . . . . . . . (2)
Equating (1) and (2), we have
x/tan 32 = (x - 66 tan 22)/tan 22
x tan 22 = x tan 32 - 66 tan 22 (tan 32)
x(tan 32 - tan 22) = 66 tan 22 (tan 32)
x = (66 tan 22 (tan 32))/(tan 32 - tan 22) = 66(0.4040)(0.6249)/(0.6249 - 0.4040) = 16.6626/0.2208 = 75.4
Therefore, the height of the building is 75.4 feet.
