The answer is:
[B]: -4 .
_____________________________Here is the problem:
_____________________ "Find f(3)."
_______________________ f(x) =
;
______________________________________
Since we are asked to find: " f(3)" ; we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is, " 3
-2" ;
and f(x) = -4 if x
-2 .
_____________________________________________________So, in this case, f(x) = f(3) = -4 ; which is: "Answer choice: [B] ".

Answer:
(x-3) (x+5) => x*x+5x-3x-15
=> x*x+2x-15
Step-by-step explanation:
Answer:
x ≈ 42.3
Step-by-step explanation:
The law of cosines is given. For this problem, ...
a = 25, b = 30, c = x , C = 100°
Filling in these values, we have ...
x^2 = 25^2 +30^2 -2(25)(30)cos(100°)
x^2 ≈ 1785.4723
x ≈ √1785.4723 . . . . take the square root
x ≈ 42.3
Answer: The other leg measures 99 feet
Step-by-step explanation:
53+28+x=180
81+x=180
