Answer:
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Step-by-step explanation:
f(x) = x⁴ + 10x³ − 20x² − 90x + 99
f(x) is a fourth order polynomial, so it has 4 roots. Use rational root theorem to find possible rational roots.
±99, ±11, ±9, ±3, ±1
By trial and error, the zeros are -11, -3, 1, and 3.
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Answer:
If you can draw one straight line through a polygon and cross more than two sides, the polygon is concave - A.
Answer:
Definition:
The Jacobian of the transformation x = f(r, θ) and y = g(r ,θ) is:
= ......[1]
Given: and
then,
and
Substitute these value in [1] ;
=
=
On simplify:
=
[ Use ]
therefore, the jacobian transformation of and is;
Jason --> 126/6 = 21 pages per hour
joe --> 115/5 = 23 pages per hour
joe reads 2 more pages per hour
hope this helps :)
