Circumfrence: pi times diameter
7.9*

circumfrence is approximatley 24.806
area:

a=

*(1/2(d))^2
a= 48.99
The correct answer is x= -1. Hope this helps!!
<span>Since charged particles cannot move across the membrane easily due to them being hydrophobic, they require a transport protein that expends energy in the form of ATP. ATP attaches onto the transport protein which changes the shape of the protein allowing ions to flow in, and it leaves a phosphate group turning into ADP.When the molecule has crossed the membrane, the phosphate group is detached from the protein.</span>
Answer: -1
Step-by-step explanation: A typical quadratic equation is
and the maximum value formula is -b/2a, so let plug it in -4/2(-4) which equals 1/2. Then let plug 1/2 into the equation,
-4(1/2)^2+4(1/2)-2=
-1+2-2=
-1
