The electric currents and magnetic materials have an
effect called magnetic field. This magnetic field is specified with its
direction and magnitude. The magnitude is the strength of the field.
the magnetic field at a distance r from a
long straight wire carrying current I can be calculated with the
equation:
B = μ I / 2 pi R
where <span>μ is a constant, I is the current and R is the radius. </span>
Answer:
Step-by-step explanation:
(6x+1)4 = 124
6x+1 = 31
x = 5
Answer:
9 p.m.
Step-by-step explanation:
Lowest common multiple (LCM) of 6 and 4.
LCM of 6, 4 = 2 × 2 × 3 = 12
After 12 hours 9 A.M. = 9 P.M.
After 12 hours at 9 P.M. she will take both medicines together again.
Options :
A. The initial number of bacteria is 7.
B. The initial of bacteria decreases at a rate of 93% each day.
C. The number of bacteria increases at a rate of 7% each day.
D. The number of bacteria at the end of one day is 360.
Answer:
C. The number of bacteria increases at a rate of 7% each day.
Step-by-step explanation:
Given the function :
f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :
The function above represents an exponential growth function :
With the general form ; Ab^x
Where A = initial amount ;
b = growth rate
x = time
For the function :
A = initial amount of bacteria = 360
b = growth rate = (1 + r) = 1.07
If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;
1 + r = 1.07
r = 1.07 - 1
r = 0.07
r as a percentage ;
0.07 * 100% = 7%
