Answer:
70
+30x-140
Step-by-step explanation:
(7x+3) (10x-14)
70-98+30x-42
70+30x-42-98
70+30x-140
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
Answer:
0.67
Step-by-step explanation:
To solve this we are going to use this lovely equation
P%•X=Y
Y is our end product
X in this case is 45
and P% is our percent
Now let's multiply 4% which becomes .004 by 45 and we get 1.8 which since there isn't 1.8 in American currency that becomes $1.80
We do the same process with the 2.5
0.025•45=1.125
Again not in the American currency so we will round 5 up and now we have $1.13
Now we subtract 1.80-1.13 which gets us 0.67 cents.
