Answer:
B. 47
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =3 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
5-3 =2
d=2
n = the term number we are looking for
an = 3 + 2(n-1)
We are looking for the 23rd term so n=23
a23 = 3 +2(23-1)
= 3 +2(22)
= 3+44
= 47
Yes both equations are equal because when you do distributive property it is the same
Answer:Values for the coefficient in the product k:
, so the first four boxes should be filled with the number "3"
Drop down arrow: "does"
Step-by-step explanation:
We perform all the products of wavelength time frequency indicated for the column of the quantity "k":
=
=
Therefore, all products of these different wavelengths and their associated frequencies render the exact same answer : 
, which means that as one of these quantities increase, the other one will decrease in the same proportion to give the same numerical answer.
This means that the two quantities are associated via inverse proportionality. As seen in the equation below, if the quantities "x" and "y" are related by inverse proportionality (shown as one equals a constant "A" divided by the other variable), their product x*y will give that constant value "A" (which in our case is .
{18,21,24,27(A),36,37,38(B)}
Area = π x r^2
Area = π x 12^2
Area = 144π or 452.16 square units. ( using 3.14 for PI)
Circumference = 2*PI *radius
Circumference = 12π or 37.68 units ( using 3.14 for PI)
