Answer:
(d) -11
Step-by-step explanation:
Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.
h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2
f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11
Then f(h(-1)) is ...
f(h(-1)) = f(2) = -11
<h2>Length of the other leg, expressed in radical form is 
</h2>
Step-by-step explanation:
We have Pythagoras theorem,
Hypotenuse² = Base² + Perpendicular²
Here we have
Hypotenuse = 9
Base = 7
Substituting
9² = 7² + Perpendicular²
Perpendicular² = 81 - 49
Perpendicular² = 32
