Thank you for posting you question here at brainly. I hope the answer will help you.
T (z) = 2/3z over z - 1/2
T(3) = 2/2.5 = 4/5 or 0.8
T(1/2) is indeterminate, he reason being that the denominator becomes zero. Division by zero gives an indeterminate result.
10+9 x 8 = 100+50+2 (152)
Since this is a right triangle, you can use the pythagorean theorem, , to find XY. Since we know that 15 and 17 are our legs and that XY is the hypotenuse, we can solve it as such:
In short, XY is √514, or 22.67 rounded to the hundreths, units long.
Here is your answer:
Therefore the answer is "65/88."
Hope this helps!
