Answer: a) 2092278989 b) 576, c) 
Step-by-step explanation:
Since we have given that
Number of students = 16
Number of desks = 16
a) How many days must pass before the class must repeat a seating arrangement?
If the number of rows = 4
b) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?
c) How many seating arrangements are there that put Larry, Moe, Curly, and Shemp in the front seats?
Hence, a) 2092278989 b) 576, c)
Answer:
9the only correct answer is 9
A quadratic should be in the form ax²+bx+c=0
where a b and c are all numbers
Answer:
TRUE
Step-by-step explanation:
tanθ = 1/cotθ
cotθ = 0 when θ = ±(1/2)π, ±(3/2)π, … ±[(2n+1)/2]π.
∴ tanθ is undefined when θ = ±[(2n+1)/2]π.
secθ = 1/cosθ
cosθ = 0 when θ = ±(1/2)π, ±(3/2)π, , …, ±[(2n+1)/2]π.
∴ secθ is undefined when θ = ±[(2n+1)/2]π.
The tangent and secant functions are undefined for the same values of θ.
ANSWER: L=13; W=9
--Please read this explanation and this will be much easier for you, it took time to type..
Set up variables first. I will lead through how to get the answer.
First get variables. So, what is Perimeter? Perimeter is like so:
P = 2L + 2W = 44ft
Now instead of using P, we'll continue with
2L + 2W = 44 because this can be used to help answer the question better than P.
"Length of the patio is 5 ft less than twice the width"
So it says "length of the patio", so we put
L =
"5 ft less than twice the width"
L = 2W - 5
Now we know what L is, and we can plug this in to our first equation!
2L + 2W = 44
L = 2W - 5
Multiply by 2...
2L = 4W - 10
Plug in...
4W - 10 (2L see?) + 2W = 44
Rearrange...
4W + 2W - 10 = 44
And solve...
=6W - 10 = 44
=6W = 44 + 10
=6W = 54
=6W/6 = 54/6
=W = 9
Now we have W. Plug this into our other equation.
L = 2W - 5
L = 2*9 - 5
L = 18 - 5
L = 13
The length of the patio is 13 ft and the width of the patio is 9 ft.
