Step-by-step explanation:
Given the expression [tex]\frac{z^{-1}}{3} \div\frac{z^{-5}}{6}[/tex], we are to write it in the form of [tex]nz^n[/tex]. To do that we will simplify the given indicinal expression as shown;
[tex]\dfrac{z^{-1}}{3} \div\dfrac{z^{-5}}{6}\\= \dfrac{z^{-1}}{3} \times\dfrac{6}{z^{-5}}\\= \dfrac{6z^{-1}}{3z^{-5}}\\ = \dfrac{2z^{-1}}{z^{-5}}\\[/tex]
According to indices [tex]\dfrac{a^m}{a^n} = a^{m-n}[/tex], the resulting equation will become;
[tex]= \dfrac{2z^{-1}}{z^{-5}}\\= 2z^{-1-(-5)}\\= 2z^{-1+5}\\= 2z^{4}[/tex]

The following points are a minimum and a maximum of a sinusoid. Complete the following steps to
model the curve using the sine function.
(4.5, 2), (1.5, 22)
a) What is the vertical shift, k, of this curve?
b) What is the amplitude, a, of this curve?
c) What is period and frequency factor, b, of this curve?
d) Write an equation using the sine function that models this curve.
Answer: K= 12
A=10
P= 6
B=pi/3
Equation: y=10sin(pi/3(x))+12
Step-by-step explanation: You can find k by finding the midline, or adding the minimum and maximum y values together and then dividing by 2.
You find a by using the midline value (12) and subtracting it from the maximum y value to get the amplitude.
To find the period, find the difference between the min and max x values, which is 3, then double it to get the full period.
To find the b value, plug it into the 2pi/b=p equation, using the period value you found before you should get pi/3.
When assembling the equation use this format: y=asin[b(x-h)]+k.
You can also graph it with a graphing calculator to check to be sure the max and min points line up.
A sine function is represented as: [tex]\mathbf{y = A\sin(Bx) + k}[/tex]
The vertical shift is 12The amplitude is 10The period is 6, and the frequency factor is [tex]\mathbf{\frac{\pi}{3}}[/tex].The sine function is [tex]\mathbf{y = 10\sin(\frac{\pi}{3}x) + 12}[/tex]The given parameters are:
[tex]\mathbf{(x_1,y_1) = (4.5,2)}[/tex]
[tex]\mathbf{(x_2,y_2) = (1.5,22)}[/tex]
(a) The vertical shift (k)
The vertical shift is calculated using:
[tex]\mathbf{k = \frac{y_1 + y_2}{2}}[/tex]
So, we have:
[tex]\mathbf{k = \frac{2 + 22}{2}}[/tex]
[tex]\mathbf{k = \frac{24}{2}}[/tex]
[tex]\mathbf{k = 12}[/tex]
(b) The amplitude (A)
The amplitude is calculated using:
[tex]\mathbf{A = \frac{y_2 - y_1}{2}}[/tex]
So, we have:
[tex]\mathbf{A = \frac{22 - 2}{2}}[/tex]
[tex]\mathbf{A = \frac{20}{2}}[/tex]
[tex]\mathbf{A = 10}[/tex]
(c) The period (p) and the frequency factor (b)
The period is calculated using:
[tex]\mathbf{p = x_1 + x_2}[/tex]
So, we have:
[tex]\mathbf{p = 4.5 + 1.5}[/tex]
[tex]\mathbf{p = 6}[/tex]
The frequency factor (b) is calculated using:
[tex]\mathbf{b = \frac{2\pi}{p}}[/tex]
So, we have:
[tex]\mathbf{b = \frac{2\pi}{6}}[/tex]
[tex]\mathbf{b = \frac{\pi}{3}}[/tex]
(d) The equation of the sine function
A sine function is represented as:
[tex]\mathbf{y = A\sin(Bx) + k}[/tex]
So, we have:
[tex]\mathbf{y = 10\sin(\frac{\pi}{3}x) + 12}[/tex]

A set of 4 consecutive even integers has a sum of 380. What is the least of the 4 integers ?
Answer:
92
Step-by-step explanation:
If the 4 consecutive even integers have a sum of 380, then the average value is 380/4.
380/4 = 95
There must be 2 integers less than 95 and 2 grater than 95.
The 4 integers are: 92, 94, 96, 98
Sum: 92 + 94 + 96 + 98 = 380
Answer: 92
The 4 consecutive even integers are 92,94,96 and 98 whose sum is 380.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The 4 consecutive even integers has a sum of 380.
x+2+x+4+x+6+x+8=380
Add the like terms
4x+20=380
Subtract 20 on both sides
4x=380-20
4x=360
Divide both sides by 4
x=90
So the four consecutive integers are
x+2=90+2=92
x+4=90+4=94
x+6=90+6=96
x+8=90+8=98
Hence, the 4 consecutive even integers are 92,94,96 and 98 whose sum is 380.

Tyler is packing lunches for a local youth program. He has 36 sandwiches, 72 apples, and 108 granola bars. What is the greatest number of lunches he can pack so that each lunch has an equal number of sandwiches, apples, and granola bars? How many of each item will the lunch contain?
Answer:
The greatest number of lunches he can pack so that each lunch has an equal number of sandwiches, apples, and granola bars is 12.
Each lunch will contain 3 sandwiches, 6 apples and 9 granola bars
Step-by-step explanation:
The greatest common divisor (GCD) of two or more numbers is the largest number by which these numbers can be divided, that is, it is the largest number that divides them all exactly.
In other words, the greatest common divisor of two numbers a and b is the largest number that divides a and divides b.
To find the greatest common divisor of two or more numbers, you start by breaking those numbers down into prime factors. In this case:
36=2²*3²
72 = 2³*3²
108 = 2²*3
The greatest common divisor is obtained by choosing only the prime factors common to the numbers, raised to the smallest exponent. That is, you choose only the common factors and those that are repeated must be raised to the minimum exponent.
The 2 appears as a prime factor in the three decompositions, whose minimum exponent is 2.
3 also appears as a common factor, whose minimum exponent is 1.
By doing the multiplication to get the greatest common divisor, you get:
2²*3=12
So the greatest number of lunches he can pack so that each lunch has an equal number of sandwiches, apples, and granola bars is 12.
To calculate how many lunches each item will contain, you simply divide the amount you have of each item by the most lunches Tyler can pack, 12.
Sandwiches: 36÷12= 3
Apples: 72÷12= 6
Granola bars: 108÷12= 9
Each lunch will contain 3 sandwiches, 6 apples and 9 granola bars

Answer:
y = 2/3x +6 for x< -3
y = 2/3x +1 for x> 3
Step-by-step explanation:
The graph is a line for x < -3
( - 6,2) and ( -3,4)
The slope is m= ( y2-y1)/(x2-x1)
m = ( 4-2)/(-3 - -6) = 2/ ( -3+6) = 2/3
The slope is 2/3
Using point slope form
y-y1 = m(x-x1) and the point ( -6,2)
y -2 = 2/3(x - -6)
y -2 = 2/3(x +6)
y-2 = 2/3 x +4
y = 2/3x +6 x< -3
The graph is a line for x > 3
(3,3) and ( 6,5)
The slope is m= ( y2-y1)/(x2-x1)
m = ( 5-3)/(6-3) = 2/ (3) = 2/3
The slope is 2/3
Using point slope form
y-y1 = m(x-x1) and the point (6,5)
y -5 = 2/3(x - 6)
y-5 = 2/3 x -4
y = 2/3x +1 x> 3

Answer:
(-162)/7 or -23 1/7 as mixed fraction
Step-by-step explanation:
Simplify the following:
(-36)/14 (-18) (-3)/6
Hint: | Express (-36)/14 (-18) (-3)/6 as a single fraction.
(-36)/14 (-18) (-3)/6 = (-36 (-18) (-3))/(14×6):
(-36 (-18) (-3))/(14×6)
Hint: | In (-36 (-18) (-3))/(14×6), divide -18 in the numerator by 6 in the denominator.
(-18)/6 = (6 (-3))/6 = -3:
(-36-3 (-3))/14
Hint: | In (-36 (-3) (-3))/14, the numbers -36 in the numerator and 14 in the denominator have gcd greater than one.
The gcd of -36 and 14 is 2, so (-36 (-3) (-3))/14 = ((2 (-18)) (-3) (-3))/(2×7) = 2/2×(-18 (-3) (-3))/7 = (-18 (-3) (-3))/7:
(-18 (-3) (-3))/7
Hint: | Multiply -18 and -3 together.
-18 (-3) = 54:
(54 (-3))/7
Hint: | Multiply 54 and -3 together.
54 (-3) = -162:

The John Jay Theater Dept has tickets at $6 for adults, $4 for teachers, and $2 for students. A total of 280 tickets were sold for one showing with a total revenue of $1010. If the number of adult tickets sold was twice the number of teacher tickets, how many of each type of ticket were sold for the showing?
Answer:
number of adults tickets sold = x = 90
number of teachers tickets = y = 45
number of students tickets = z = 145
Step-by-step explanation:
Cost of tickets
Adults = $6
Teachers = $4
Students = $2
Total tickets sold = 280
Total revenue = $1010
Let
x = number of adults tickets
y = number of teachers tickets
z = number of students tickets
x + y + z = 280
6x + 4y + 2z = 1010
If the number of adult tickets sold was twice the number of teacher tickets
x = 2y
Substitute x=2y into the equations
x + y + z = 280
6x + 4y + 2z = 1010
2y + y + z = 280
6(2y) + 4y + 2z = 1010
3y + z = 280
12y + 4y + 2z = 1010
3y + z = 280 (1)
16y + 2z = 1010 (2)
Multiply (1) by 2
6y + 2z = 560 (3)
16y + 2z = 1010
Subtract (3) from (2)
16y - 6y = 1010 - 560
10y = 450
Divide both sides by 10
y = 450/10
= 45
y = 45
Substitute y=45 into (1)
3y + z = 280
3(45) + z = 280
135 + z = 280
z = 280 - 135
= 145
z = 145
Substitute the values of y and z into
x + y + z = 280
x + 45 + 145 = 280
x + 190 = 280
x = 280 - 190
= 90
x = 90
Therefore,
number of adults tickets sold = x = 90
number of teachers tickets = y = 45
number of students tickets = z = 145
-10b + 5 = 7b + 5 what is b
Answer:
0?
Step-by-step explanation:
Original Equation:
-10b + 5 = 7b + 5
Add 10b to both sides
5 = 17b + 5
Subtract 5 from both sides.
0 = 17b
Divide both sides by 17
