A rock is tossed vertically from a height of 2m with an initial velocity of 20 ms-1. The height of the rock, h, after t seconds can be modeled by the polynomial function :h(t)=−4.9t2+20t+2, t≥0. Calculate how many seconds, rounded to three significant figures, it takes for the rock to hit the ground.

Answers

Answer:

The rock takes 4.18 seconds to hit the ground

Step-by-step explanation:

Function Model

The height of a rock h, after t seconds, can be modeled by the polynomial function:

[tex]h(t)=-4.9t^2+20t+2, t\geq 0[/tex]

When the rock hits the ground, the height is 0, thus we need to find the value of t such as:

[tex]-4.9t^2+20t+2=0[/tex]

A quadratic equation can be expressed as:

[tex]at^2+bt+c=0[/tex]

where a,b, and c are constants.

Solving with the quadratic formula:

[tex]\displaystyle t=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The values for the given equation are:

a=-4.9, b=20, c=2

Applying the formula:

[tex]\displaystyle t=\frac{-20\pm \sqrt{20^2-4(-4.9)(2)}}{2(-4.9)}[/tex]

[tex]\displaystyle t=\frac{-20\pm \sqrt{400+39.2}}{-9.8}[/tex]

[tex]\displaystyle t=\frac{-20\pm 20.957}{-9.8}[/tex]

There are two possible solutions:

[tex]\displaystyle t=\frac{-20- 20.957}{-9.8}=4.18[/tex]

[tex]\displaystyle t=\frac{-20+ 20.957}{-9.8}=-0.1[/tex]

Since t > 0, the only solution is t=4.19 seconds

The rock takes 4.18 seconds to hit the ground

Please help! A line has a slope of -2 and a y-intercept of -3. Graph the line using the slope and y-intercept. Which of the following points lie on this same line? Check all that apply.

Answers

Answer:

2. -1.5, 0

3. -6, 9

5. 3, -9

Step-by-step explanation:

Given parameters:

Slope = -2

y - intercept = -3

Unknown:

The point that lies on the line = ?

Solution:

To do the equation of the line,

y = mx + c

y and x are the coordinates

m is the slope

c is the y -intercept

Input the parameters:

y= -2x -3

The points that lie on the line will conform with the equation:

y + 2x = -3

1. -2, 0

y = 0 and x = -2

0 + (-2)2 = -4

2. -1.5, 0

y = 0 and x = -1.5

0 + 2(-1.5) = -3

3. -6, 9

y = 9, x = -6

9 + 2(-6) = 9 - 12 = -3

4. 2, -3

y = -3 and x = 2

-3 + 2(2) = -3 + 4 = 1

5. 3, -9

y = -9, x = 3

-9 + 2(3) = -9 + 6 = -3

6. -4, 4

y = 4 , x - 4

4 + 2(-4) = 4 - 8 = -4

The boldened coordinates line on the same line.
