Work shown above! Answer is the 3rd Choice!
(y - 10)^2 is what I come up with, let me know if this helps.
Answer:
a
Step-by-step explanation:
In any function of the form f(x) = a(b^x), the initial value is always <em>a</em> because it is not dependent on <em>x</em>.
Use the Pythagorean theorem to find z:
z = √(6^2 + 9^2)
z= √(36 + 81)
z = √117
z = 3√13 = 10.8
Use leg rule to find x:
x/6 = 6/9
Cross multiply:
9x = 36
Divide both sides by 9:
x = 36/9
x = 4
Use Pythagorean theorem to find y:
y = √(6^2 + 4^2)
y= √(36 + 16)
y = √52
y = 2√13 = 7.2
