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:
240 square feet
Step-by-step explanation:
Hello, I can help you with this
Step one
find the real scale
According to the data
scale is 1 in : 2 ft
also remember 1ft=12 inches
so
scale is 1in: 2(12 inches)
scale is 1 in :24 in
the purpose of use inches a unit in both sides is to eliminate the, the scale must be adimensional
so escales is
1:24 , this means, that a measure on the blueprint must be multiplied by 24 to know its real value
Step 2
with the escale find the real dimensions, you can use a rule of three
Abraham's bedroom is 6 inches wide
blueprint ⇔ bedroom
1 in ⇔ 24 in
6 in ⇔x
x=(6*24)/1
x=144 inches=12 ft
Abraham's bedroom is 10 inches long
1 in ⇔ 24 in
10 in ⇔y
y=(10*24)/1
x=240 inches=20 ft
Step 3
find the area
the area is wide *long
area=x*y
area=12ft*20ft
area=240 square feet.
Have a good day
Option 1 =$497.5 option 2 =$494.5 option 3 =$50.5
Answer:
a)
a1 = log(1) = 0 (2⁰ = 1)
a2 = log(2) = 1 (2¹ = 2)
a3 = log(3) = ln(3)/ln(2) = 1.098/0.693 = 1.5849
a4 = log(4) = 2 (2² = 4)
a5 = log(5) = ln(5)/ln(2) = 1.610/0.693 = 2.322
a6 = log(6) = log(3*2) = log(3)+log(2) = 1.5849+1 = 2.5849 (here I use the property log(a*b) = log(a)+log(b)
a7 = log(7) = ln(7)/ln(2) = 1.9459/0.6932 = 2.807
a8 = log(8) = 3 (2³ = 8)
a9 = log(9) = log(3²) = 2*log(3) = 2*1.5849 = 3.1699 (I use the property log(a^k) = k*log(a) )
a10 = log(10) = log(2*5) = log(2)+log(5) = 1+ 2.322= 3.322
b) I can take the results of log n we previously computed above to calculate 2^log(n), however the idea of this exercise is to learn about the definition of log_2:
log(x) is the number L such that 2^L = x. Therefore 2^log(n) = n if we take the log in base 2. This means that
a1 = 1
a2 = 2
a3 = 3
a4 = 4
a5 = 5
a6 = 6
a7 = 7
a8 = 8
a9 = 9
a10 = 10
I hope this works for you!!
if we're factoring you can use the AC method. A multiplied by C is 24. and 4x6 is 24.
(x+4)(x+6) is your answer
