PROBLEM 2 The height of a golf ball in feet can be determined using the formula h(t) = -16t2 + 100x , where t is the number of s

wolverine [178]

Answer:

Step-by-step explanation:

Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;

$h(t) = -16t^2 + 100x\\\\h(2.5) = -16(2.5)^2 + 100(2.5)\\\\h(2.5) = -16(6.25) + 250\\\\h(2.5) = -100+250\\\\h(2.5) = 150\\\\$

Hence the height of the golf after 2.5 seconds is 150ft.

What is the distance to the earth's horizon from

shepuryov [24]

Answer: 216.2 miles

Step-by-step explanation:

Alright, lets get started.

As the diagram shows, the line from point P is tangent to earth's curvature.

It means it is making right angle.

So the triangle formed will be right triangle.

Hence we can use Pythagorean theorem in it.

So from point P to center of earth, it will be hypotenuse of triangle.

$c^2=a^2+b^2$

$(3959+5.9)^2=3959^2+x^2$

$3964.9^2=3959^2+x^2$

$15720432.01=15673681+x^2$

$x^2=46751.01$

taking square root, the x will be :

$x = 216.2$

hence the value of x is 216.2 miles. : Answer

Hope it will help :)

Hexagon DEFGHI is translated on the coordinate plane below to create hexagon D'E'F'G'H'I': Hexagon DEFGHI and Hexagon D prime E

BigorU [14]

We write the translation one by one:

D (3, 5)

D' (-6, 2)

That translates to: (x - 9, y - 3), because that is for passing from D to D': (3 - 9, 5 - 3) = (-6, 2).

Therefore if it is true for D and D' then, it has to be true for all others (you can check) for that rule to be true, so the correct answer is:

(x, y)→(x − 9, y − 3)
