The volume flow rate of the air being pumped into the football will be given by:
Q=V*A
Where
V=Speed
A=Area
You know that your pump expels air at speed of 8.2 ft/s
The area of The needle of your pump is
A=pi*r^2=pi*((4.5/1000)*(3.28))^2=0.00068442 ft^2
Finally
Q=V*A=(8.2 ft/s)*(0.00068442ft^2)=0.005612243 ft^3/s
Since a atom of chlorine has 36 fewer protons than an atom of iodine, then their total is 70.
So you have to subtract 36 from 70
70 - 36
= 34
*your answer is 34 protons for an atom of iodine
Given:
The given quadratic equation is:
To find:
The solution for the given quadratic equation in simplest form by using the quadratic formula.
Solution:
Consider a quadratic equation is defined as 
, then the quadratic formula is:
The given quadratic equation is:
We have, 
. Using the quadratic formula, we get
![[\because \sqrt{-a}=i\sqrt{a}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B-a%7D%3Di%5Csqrt%7Ba%7D%5D)
The solutions of the given equations are 
and 
.
Hence, the correct option is B.
although you come up with 50 you have to pay attention to the significant figures and realize that the seconds only have 1 figure so the answer then becomes 5.
The answer would be B
First, you solve the equation (-2a-5>3=-2a>8=a>-4). Since a>-4 would be our final solution, we have to graph a as anything above -4.
