Suppose h(t) = -0.2t? + 2t models the height, in feet, of a ball that is kicked into the air where t is

ipn [44]

Answer:

Below in BOLD.

Step-by-step explanation:

h(t) = -0.2t^2 + 2t

We can find the maximum height and the time by converting to vertex form:

h(t) = -0.2(t^2 - 2t)

= -0.2[(t - 1)^2 - 1)

= -0.2(t - 1)^2 + 0.2

The time to get to maximum height = 1 second and the maximum height is 0.2 m.

When the ball reaches the ground h = 0 so

-0.2(t - 1)^2 + 0.2 = 0

(t - 1)^2 = -0.2 / -0.2 = 1

t - 1 = 1

t = 2 seconds.

What is the equation of the line shown in this graph? graph shown down below

Andrew [12]

Answer: $x = -2$

Step-by-step explanation:

In the given picture , the line is parallel to the y- axis and passing through (-2,2) and (-2 , -3).

The equation of line parallel to y-axis (has slope undefined) is given by

x= a , where a is the point on x-axis through which the line is passing .

For the given graph , the line is passing through x = -2.

Therefore , the equation of the given line = $x = -2$

Hence, the correct answer = $x = -2$

1.5( x + 4) -3 = 4.5 ( x - 2 )

Hitman42 [59]

Answer:

Step-by-step explanation:

1.5(x + 4) - 3 = 4.5(x - 2)

1.5x + 6 - 3 = 4.5x - 9

1.5x + 3 = 4.5x - 9

3 + 9 = 4.5x - 1.5x

12 = 3x

12/3 = x

Which equation is the inverse of f(x)=LaTeX: \frac{1}{x+2}1 x + 2 A. LaTeX: f^{-1}\left(x\right)=\frac{1}{x}+2f − 1 ( x ) = 1 x

inna [77]

Answer:

$g^{-1}x = \frac{1-2x}{x}$

Step-by-step explanation:

Given the function $g(x)= \frac{1}{x+2}$ , we are to find the inverse of the function and this can be done y following the simple steps:

Step 1: Replace y with $g(x)$

$g(x)= \frac{1}{x+2}\\y= \frac{1}{x+2}$

Step 2: Interchange x with y

$x= \frac{1}{y+2}$

Step 3: Make y the subject of the formula;

$x= \frac{1}{y+2}\\y+2 = \frac{1}{x}\\y = \frac{1}{x} - 2\\Find \ the\ LCM\\y = \frac{1-2x}{x}$

Step 4: Replace y as $g^{-1}(x)$

$g^{-1}x = \frac{1-2x}{x}$

Hence the inverse of the function is $g^{-1}x = \frac{1-2x}{x}$
