Solve for t. d=−16t2+4t t=12±41−4d‾‾‾‾‾‾√ t=8±1−4d‾‾‾‾‾‾√ t=18±1−4d√8 t=12±41−4d√2

Answer:

$t=\dfrac{1}{8}\left(1\pm\sqrt{1-4d}\right)$

Step-by-step explanation:

Rearranging your quadratic to standard form, you get ...

16t^2 -4t +d = 0

For the quadratic formula, you have ...

a = 16

b = -4

c = d

so the solution is ...

$t=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t=\dfrac{-(-4)\pm\sqrt{(-4)^2-4(16)(d)}}{2(16)}=\dfrac{4\pm 4\sqrt{1-4d}}{32}\\\\t=\dfrac{1}{8}\left(1\pm\sqrt{1-4d}\right)$

I need help on this anyone

DanielleElmas [232]

Perimeter = 2L + 2W

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

Perimeter = 8x^2 + 2y^2

x^2 - 7x^2 = -6x^2

-3x - -2x = -3x +2x = -x

8 - -1 = 8+1 = 9

Answer = -6x^2 -x + 9

9x^2 -4x - 3x^2 -2x

9x^2 - 3x^2 = 6x^2

-4x - -2x = -4x +2x = -2x

Answer = 6x^2 -2x

Which is greater 2/9 to 1/5

BARSIC [14]

First, find the common denominator.

5 x 9 = 45

1/5 = 9/45 (1 x 9 = 9)

2/9 = 10/45 (2 x 5 =10)

<span>So, 2/9 is greater than 1/5 because 10 is greater than 9</span>
