Okay so you have to figure out all the possible ways to get six or higher. between a 6 sided dice and a 4 sided dice. We do 6*24 to find all the possibilities.

The probability of getting a 6 or higher is 14/24

The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation h = -16t2 + h0, where

lawyer [7]

$\bf h=-16t^2+255\implies h=-16t^2+0t+255
\\\\\\
~~~~~~~~~~~~\textit{quadratic formula}\\\\
\begin{array}{lcccl}
h=& -16 t^2& +0 t& +255\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array} 
\qquad \qquad 
h= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}
\\\\\\
h=\cfrac{-0\pm\sqrt{0^2-4(-16)(255)}}{2(-16)}\implies h=\cfrac{\pm\sqrt{16320}}{-32}
\\\\\\
h=\cfrac{\pm\sqrt{8^2\cdot 255}}{-32}\implies h=\cfrac{\pm 8\sqrt{255}}{-32}\implies h=\cfrac{\mp \sqrt{255}}{4}
\\\\\\
h\approx \mp 3.992179856$

60 POINTS AND BRAINLY

kkurt [141]

Answer:

Step-by-step explanation:

Multiply the parenthesis

2*x = 2x

2*5 = 10

2x-10 = 12

Because we subtract 10 to get 12, we add 10 to see the 2x

12+10 = 22

Now 2x = 22

2x=22

2x / 2 = 22 / 2

x=11

Please help me thank you

notsponge [240]

Answer: a=60, b= 50, c= 180-148=32, d=64, e=d=64, g=180-125=55 and since f=g then f=55, h= 76, I=h=76, j= 180-76= 104

Sorry I cannot explain why they are true because I only learn them in my language so I can’t explain them clearly in English but there is the answer
