The problem has the equation:
f(x) = (3) ^ (x/2)
In order to get the average increase in the number of flowers being pollinated from day 4 to day 10, then we need to use the equation substituting x with 4 to 10
f(4) = 9
f(5) = 12.59
f(6) = 27
f(7) = 46.77
f(8) = 81
f(9) = 140.30
f(10) = 243
Then add all the values and divide it by 7
= 559.66 / 7
= 79.95
So the correct answer is 79.95
1/10x = 0.49
x = (0.49) / (1/10)
x = 0.49 * 10/1
x = 4.9 <==
The answer is -3, Choice 1 because you only need to care about the x values, so what do you add/subtract from 8 you get 5? So the answer is -3
The answer for ''4x = 5x - 12'' would be x = 12.
4x - 5x = 12 (subtract 5x from both sides)
-x = -12 (simplify 4x - 5x to -x)
x = -12 ( multiply both sides by -1) .
For the 2nd one ''10p + 5 = 18p - 6/2''
The answer is 1 not those choices
10p + 5 = 18p - 3
5 = 18p - 3 - 10p
5 = 8p - 3
5 + 3 = 8p
8 = 8p
1 = p
p = 1.
