Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
Answer: C
Step-by-step explanation:
For this problem, we know that customers already have to pay $5 just to enter the farm. The $5 is basically a flat fee. Our equation would be:
y=5+____
Now, we know that the apples cost $2.50 per pound. Our final equaiton would be:
y=5+2.5x
Step-by-step explanation:
Given the table:
Month f(x) = Number of imports g(x) = Number of exports
January (1) 3 1
February (2) 4 3
March (3) 5 5
April (4) 6 7
From the table, it is clear that:
Number of imports = number of month + 2
so

also
Number of exports = 2(number of month) + 1
so

Therefore, number of imports equals the number of month plus one. i.e.
, which is a linear function.
If we compare it with slope-intercept form of the line

Then,
slope = m = 1
y-intercept = 2
Also number of exports equals is also a linear function.
i.e. 
Here,
slope = m = 2
y-intercept = -1
6000 pounds per day is equal to 21,000 tons per week
