Answer:

The inverse of the function is ±sqrt( (x+4)/2

Step-by-step explanation:

Set the function equal to y

y = 2x^2 -4

Exchange x and y

x = 2y^2 -4

Solve for y

Add 4 to each side

x+4 = 2y^2 -4+4

x+4 = 2y^2

Divide each side by 2

(x+4)/2 = 2/2y^2

(x+4)/2 = y^2

Take the square root of each side

±sqrt( (x+4)/2 )= sqrt(y^2)

±sqrt( (x+4)/2 )= y

The inverse of the function is ±sqrt( (x+4)/2

H=255-21t-16t^2<br><br> PLEASE HELP!!
Colt1911 [192]

Answer:

3.15 seconds is the answer.

<u>Explanation</u>

when the ball touches the ground, h =0

hence,

0=255-21t-16t²

16t²+21t-225=0

here a=16 ,b=21, c= -225

t=   \frac{ - b± \sqrt{ {b }^{2}  - 4ac} }{2a} \\  \\ t=   \frac{ - 21± \sqrt{ {21}^{2}  - 4 \times 16 \times  - 225} }{2 \times 16} \\  =  \frac{ - 21 ± \sqrt{441 - ( - 14400)} }{32} \\  =  \frac{ - 21± \sqrt{14841} }{32}  \\  =  \frac{ - 21±121.82}{32}  \\  \\ t =   \frac{ - 21 + 121.82}{32}  \: or \:  \: t =  \frac{ - 21 - 121.82}{32}  \\ t = 3.15 \:  \: or \:  \: t =  - 4.46

time cannot be negative, hence t = -4.46 can be avoided

The ball takes 3.15 seconds to hit the ground.

1) There is a jar containing 100 marbles: 40 of the marbles are red, 30 are blue, 20 are white, and 10 are black. You are blindf
Ainat [17]
A. The probability that you would select a black marble is 10/100. Which is also 1/10.
B. It would be 10/60. Which is 1/6.

For the first you count how many black marbles are in the jar total? There is 10. Which means 10/100.

For the second the red marbles doesn’t count so now we have only 60 marbles in the jar. 10 of those marbles are still black.

Please vote my answer brainliest! Thanks.
