Answer:

D. -6 + 2\sqrt{5}

Step-by-step explanation:

The answer is D because to solve for X you use the quadratic formula which is...

-b±\sqrt{b^{2} - 4ac}

now just plug in which would be

-6±\sqrt{6^{2} - 4(1)(4) }

then solve and the final answer would be

-6 ± 2\sqrt{5} but there is only one answer for this which is a positive that is how I got  

-6 + 2\sqrt{5}

A ball is thrown from ground level straight up into the air at an intitial velocity of 54 feet per second. The height of the bal
bonufazy [111]

Answer:

3 3/8 seconds.

Step-by-step explanation:

When it reaches the ground h = 0 so:

54t - 16t^2 = 0

16t^2 - 54t = 0

2t(8t - 27) = 0

t = 0 or t =  27/8   (we ignore the t = 0 ) so:

t =   3 3/8 seconds.

Ainat [17]

Answer:

Graph A → Equation A → Table B → Property D

Graph D → Equation B → Table A → Property B

Graph B → Equation C → Table C → Property E

Graph C → Equation D → Table E → Property A

Graph E → Equation E → Table D → Property C

Step-by-step explanation:

Graph A corresponds to equation A, x·y = 2, and Table B → Property D

xy = 2 has a vertical asymptote at x = 0, and a horizontal asymptote at y = 0

y = 2/x, when x = 0, y = ∞

Graph D corresponds to equation B, -\left |  x\right | + 1 which corresponds to table A → Property B

The domain extends from (-∞, ∞), and [1, -∞)

Graph B corresponds to equation C, -(x + 2)² which gives the values in Table C and Property E wich is a horizontal shift of 2 units left and a reflection across the x-axis

Graph C corresponds to equation D, (1/3)·x - 2, which gives the values on Table E and Property A

The y-intercept of (1/3)·x - 2 = (0, -2), and the x-intercept = (6, 0)

Graph E corresponds to equation E, x³ = y, which gives the values on Table D  Property C, y is x cubed

Given the arithmetic sequence an= 2 - 3(n - 1), what is the domain for n?
wel
Generally we use n as a counter and begin it with 1:  the first term is obtained when n = 1.  Thus, n must be a positive integer, 1 or greater:  {1, 2, 3, ... }.
