F(x)=2^x+6
let f(x) = n
f^-1(n) = x
x = 2^n + 6
x - 6 = 2^n
2^n = x - 6
log 2^n = log (x-6)
n log 2 = log (x-6)
n = (x-6)/2
f^-1(x) = (x-6)/2
The number of loaves of white bread more than whole meal bread that are produced in a day are 1760.
We are given that:
A factory produces 6 times as many loaves of white bread as whole meal bread in a day that is:
Let the number of whole meal bread be a variable say x.
So, the number of loaves of white bread = 6 x.
Now, we are given that:
number of loaves of white bread = 2640
6 x = 2640
x = 2640 / 6
x = 880
The number of loaves of white bread more than whole meal bread that are produced in a day = 2640 - 880 = 1760
Therefore, we get that the number of loaves of white bread more than whole meal bread that are produced in a day are 1760.

Answer:
x=71
Step-by-step explanation:
Since this is an isosceles triangle the bottom 2 angles are equal.
The three angles of the triangle are x, x, and 38. They must add to 180 degrees
x+x+38 = 180
Combine like terms
2x+38=180
Subtract 38 from each side
2x+38-38 = 180-38
2x = 142
Divide each side by 2
2x/2 =142/2
x =71
Answer:
After 120 seconds
Step-by-step explanation:
Here, we want to know the number of seconds after which both spotlights will change colors at the same time again.
Basically, what we want to do here is to
calculate the value with which 30 and 40 have the same multiples or we want to
calculate the lowest common multiple of 30 and 40
The multiples of 30 are 30,60,90,120 etc
The multiples of 40 are 40,80,120 etc
We can see that the lowest common multiple of both is 120
So therefore the spotlights will change colors at the same time after 120 seconds
