Answer:

Step-by-step explanation:

A man steps out of a plane at 4,000m of height above the ground.The point at which he jumps out of the plane would make a good reference point. However, if his acceleration is going to change as a result of him opening his parachute 2000m above the ground, a good reference point would be there. Keep in mind though, that his velocity at that instant would need to be known for it to be useful- otherwise the airplane reference point would be just as good with appropriate modeling....

The function f(x)=x^2is graphed above. which of the graphs below represents the function g(x)=x^2-3
steposvetlana [31]

Answer:

The graph which is translated 3 down, represents the function g(x)=x^2-3

Step-by-step explanation:

Top of f has coordinates (0, 0).

Top of g has coordinates (0, -3).

When you just look at the y-coordinates of f(x) and g(x), you see that the top of g(x) is 3 lower the that of f(x).

The graph which is translated 3 down, represents the function g(x)=x^2-3

<h2>Answer:</h2>

P=(19+50x)ft

<h2>Step-by-step explanation:</h2>

A rectangle is a quadrilateral whose angles are all right angles. In this problem, we have a rectangle whose height h=9ft and whose area is A=225xft^{2}. We don't know the other side of the rectangle, but let's call it w. So the area of a rectangle is:

A=h.w

The perimeter is the distance around a shape in two dimensions. For our rectangle, our perimeter is:

P=2h+2w

So our goal is to find w. From the equation of the area:

w=\frac{A}{h} \\ \\ w=\frac{225x}{9}=25x

If we substitute both this value and the height in the equation of the perimeter we get:

P=2(9+25x)ft \\ \\ \boxed{P=(19+50x)ft}

Help please <br><br>numbers 46, 47, 48
pentagon [3]

Answer:

46. ΔQRP ≅ ΔUTV

47. y = 42

48. ∠KMN = 101°

Step-by-step explanation:

46. It is convenient to name the vertices in the order of the number of arc identifying the angle. Corresponding vertices need to be named in the same order in the congruence statement.

47. From the sum of angles of a triangle, you know that ...

  x +62 +65 = 180

  x = 180 -127 = 53

  x - y = 11 since the corresponding sides are the same length

  53 - y = 11 . . . . . .substitute the value of x

  y = 53 - 11 . . . . . . add y-11

  y = 42

48. The exterior angle has the same measure as the sum of the opposite interior angles:

  81 +4x = 13x +36

  45 = 9x . . . . . . . . . add -4x-36

  5 = x . . . . . . . . . . . divide by 9

  ∠KMN = (13x +36)° = (13·5 +36)° = 101°
