Answer:
1.)1.3
2.)0.13
3.)13
4.)0.13
5.)True, because multiplying by .001 is the same as dividing by 1000
Step-by-step explanation:

Since the above polynomial is of degree 7, 7 roots exist.
If the degree is odd and the polynomial coefficients are real, there will be at least one real root, since complex roots come in conjugates.
For the given problem, there is exactly one real root. All the rest are complex.</span>
After 5 hours, the northbound train is
(30 mph) (5 h) = 150 mi
north of the station, while the eastbound train is
(40 mph) (5 h) = 200 mi
east of the station.
The distance between the trains is the length of the hypotenuse in the right triangle formed by the trains' paths. By the Pythagorean theorem, this distance is
Answer:
y = 55 degrees.
Step-by-step explanation:
the angles of a triangle add up to 180 degrees, so
40 + y + y + 30 = 180
2y = 180 - 70
2y = 110
y = 55.
C because if you multiply 7x7.50 than add 5 till you get 72.50
