I think
A. convert the time to seconds, so all the time are 7070sec and the total course to meter.
so 31300meter
Vector = TotalCourse÷total time
V=31300/7070=4.427157m/s
convert it to km/h so 4.427157×36÷10=
15.9377km/h
B. 45÷15.9377=2.823Hour
it means that around 2 Hour 48Minutes more.
i think the teacher need to simplify it
(57/19)*65=195
is the answer.
Answer:
20x+21y+14
Step-by-step explanation:
Combine like terms:
150x-80y+50-50x-25y+20=
100x-80y+50-25y+20=
100x-105y+50+20=
100x-105y+70
100x-105y+70 can be divided by 5 and get 20x+21y+14.
either a rectangle or circle will be made. If you cut it horizontially you will get a circle. Vertically and you will have a rectangle
The roots of
are 0 (multiplicity 2), -3 (multiplicity 1),
(multiplicity 1) and
(multiplicity 1).
The characteristics of the polynomial can be derived from algebraic techniques. Roots and multiplicity can be found by <em>factoring</em> the polynomial. The multiplicity is represented by a power binomial of the form:
(1)
Where
is the grade of the polynomial.
Now we proceed to factor the formula:



Please notice that
have two complex roots.

The roots of
are 0 (multiplicity 2), -3 (multiplicity 1),
(multiplicity 1) and
(multiplicity 1).
