There are no left or right vectors during free fall, so they are technically equal.
gravity is more powerful than air resistance, so it's vector will be longer.
The answers are the first option and third option.
Answer:
<h3>C.) The area of EFGH is always ¹/₂ of the area of the rectangle. </h3>
Step-by-step explanation:
If EG is parallel to the side of the rectangle then lenght of EG is equal to width of rectangle.
If F and H are midpoints of sides of rectangle then FH is parallel to the side of rectangle {wich is perpendicular to the side parallel to EG}. That means the lenght of FH is equal to lenght of rectangle, and FH is perpendicular to EG.
Then FH is sum of hights of triangles EFG and EHG , and the area of EFGH is sum of areas of triangles EFG and EHG .
So the area of the rectangle:
The area of the kite:
No matter the height of the triangles, so no matter the location of the EG
The total is $87.2 you have to first change the percentage to a decimal so 0.09x80=87.2
Answer:
if you bought 60 feet of copper pipe at $1.25 per foot, the total price would be $75
Step-by-step explanation:
since you are buying 60 feet of copper pipe, you would multiply the amount at which it costs per foot. 60×1.25=75

1) Answer 4.
Explanation.
The number of total roots of a polynomial is the degree of the polynomial. In this case it is 4.
The real, i.e. non-complex roots of a polynomial correspond to the x-intercepts of the graph. Then you can graph the polyomial to see how many real roots it has.
The graph of this polynomial shows that it does not cross or touch the x-axys which means that there are not real roots. Thereafter the 4 roots are complex.
2) The multiplicity of a root is the number of times that the corresponding factor appears in the polynomial. In this case the factor x + 1 appears two times, then - 1 has multiplicity 2.
3) You can either graph the polynomial or factor it.
If you factor it you will find:
x^4 - x^3 - 9x^2+7x+14 = (x +1)(x -2)(x^2 -7).
The there are 4 zeroes or 4 real roots.
