Answer:
-5
Step-by-step explanation:
The leading coefficient means the thing you're multiplying your highest power by. Here, your highest power of x is x^2, and that term's coeff. is -5, so the leading coefficient is -5.
Answer:
csc^2x
Step-by-step explanation:
It's a trig identity where 1+cot^2x = csc^2x

Answer: 12
Step-by-step explanation:
Answer:
Radius = 2 cm.
Step by step explanation:
By the Pythagoras theorem the third side of the triangle
= sqrt (6^2 + 8^2)cm = sqrt100 = 10cm.
The formula for the radius of the circle is
r = sqrt [ (s - a)(s-b)(s-c)/ s ] where a,b,c are side lengths and s = the semi perimeter.
Here s = ( 6+8+10) / 2 = 12
So the radius r
= sqrt [ (12-6)(12-8)(12-10)/ 12 ]
= sqrt 4
= 2 (answer).
