214/1000 is this as a fraction
Among the coefficient signs (++-) there is one sign change, so Descarte's rule of signs tells you there is one positive real root. Changing x to -x does not affect the signs, so there is also one negative real root. Then there are two complex roots to bring the total number to 4, the degree of the polynomial.
The factorization is
f(x) = (x^2 +25)(x^2 -4)
Each of these can be factored using the form for factoring the difference of squares.
f(x) = (x -5i)(x +5i)(x -2)(x +2)
There are 2 real roots: ±2.
There are 2 imaginary roots: ±5i.
1/10 is 10 times=
1/10 divided by 10=
copy dot flip
1/10 X 1/10= 1/100
because 1/10 is 10x more than 1/100
Answer:
200,7 miles
Step-by-step explanation:
Proportions:
223 miles ⇔ 10 gallons
D miles ⇔ 9 gallons
D = 223*9/10
D = 200.7 miles
Answer:
3
Step-by-step explanation:
The coordinates of B ( 4,0)
The coordinates of C = (5,3)
The slope is
m = (y2-y1)/(x2-x1)
= (3-0)/(5-4)
= 3/1
= 3
