Answer:
x = 2
Step-by-step explanation:
Using Pythagoras' identity on each of the 3 right triangles
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Outer right triangle
x² + z² = (9 + 4)² = 13² = 169, that is
x² + z² = 169 → (1)
Left right triangle
y² + 4² = x²
y² + 16 = x² ⇒ y² = x² - 16 → (2)
Right right triangle
z² = y² + 9²
z² = y² + 81 → (3)
Substitute (3) into (1)
x² + y² + 81 = 169 ← substitute (2) into here
x² + x² - 16 + 81 = 169
2x² + 65 = 169 ( subtract 65 from both sides )
2x² = 104 ( divide both sides by 2 )
x² = 52 ( take the square root of both sides )
x =

Answer:
Step-by-step explanation:
Let C represent number of dairy cows.
We have been given that each dairy cow produces 3500 gallons of milk per year. So amount of milk produced by C cows in 1 year would be gallons.
We are also told that the dairy sells milk for 2.00 per gallon. So yearly income I, in dollars for the dairy milk production would be 2.00 times the yearly milk production.
Since yearly milk production from C cows is , so Income would be:
Therefore, the formula represents yearly income (I) as a linear function of C.
