Answer:
see attached
Step-by-step explanation:
a) One way you can try to identify the pattern is to look for the differences between the images shown, then divide those differences by 2. For example, the total number of vertical dots is 2, then 4 in patterns 2 and 4. This suggests the total number of vertical dots is equal to the pattern number..
The total number of horizontal dots is 4, then 6 in patterns 2 and 4. This suggests that the number of horizontal dots increases by 1 in each pattern. This would mean pattern 1 would have 3 total horizontal dots and 1 total vertical dot. It will look like one row of 3 dots.
Pattern 3 will have 5 total horizontal dots and 3 total vertical dots. The sequence of patterns will look like the attachment.
__
b) The total number of dots in each pattern is 2×(pattern number) +1. Then the number of dots in Pattern 7 will be 2×7 +1 = 15 dots.

Answer:
clockwise90°originStep-by-step explanation:
The answer statement tells you the transformation is a rotation. The original is in the 2nd quadrant, and the image is in the 1st quadrant, representing a clockwise rotation. AB points east, while A'B' points south, a rotation of 90° (clockwise). Each image point is the same distance from the origin as its preimage point. The origin is the center of rotation.

(del^(2)z)/(delx^(2))-4(del^(2)z)/(delxdely)+4(del^(2)z)/(dely^(2))=e^(2x+y)
Answers
Using Dz and D'z to denote partial derivatives of z with respect to x and y respectively, the equation becomes (D^2 -1)z=0 or (D-1)(D+1)z=0. Put (D+1)z = u(x,y). Then we have (D-1)u =0. The general solution of this equation is u(x,y)=A(y).e^x, where A(y) is an arbitrary function of y, because we have integrated a partial derivative of u with respect to x, and we have to take an arbitrary function of y instead of an arbitrary constant.
Now the original equation becomes
(D+1)z=A(y)e^x and we integrate it with respect to x, giving ze^x = Int[e^x.A(y).e^x.dx] + B(y), (for another arbitrary function B(y)) = (1/2)e^(2x).A(y) +B(y) or
z(x,y) = B(y)e^(-x)+[A(y)e^x]/2 or
z = B(y)e^(-x) + C(y)e^x. Hence putting x=0,
e^y = B(y)+C(y) and Dz= -e^(-x)B(y) + e^x.C(y). Again putting x=0, we get 1 = -B(y) + C(y). Solving the two equations in B(y) and C(y), we have C(y) = (1+e^y)/2, and B(y) = (e^y -1)/2. Hence the required solution is
z = [(e^y -1).e^(-x)]/2 + [(e^y +1).e^x]/2 =
z = (e^y)cosh(x) + sinh(x).

Answers
Answer:
250 $3 tickets and 100 $2 tickets were sold.
Step-by-step explanation:
A family bought a total of 13 tickets to a magic show, some adult and some child. The family paid a total of $85 Adult tickets are $15 each and tickets are $5 each. Let X represent adult tickets. Let y represent child tickets Write an equation to model the total amount of money that they spent.The cost of tickets for a play is $3.00 for adults and $2.00 for children. 350 tickets were sold and $950 was collected. How many tickets of each type were sold?
Let x = number of $3 tickets
Let y = number of $2 tickets
Total = quantity × value
quantityvaluetotal$3 ticketsx33x$2 ticketsy22ytogether350950
Step 3: Add down each column to get the equations
x + y = 350 (equation 1)
3x + 2y = 950 (equation 2)
Use Substitution Method
Isolate variable x in equation 1
x = 350 – y (equation 3)
Substitute equation 3 into equation 2
3(350 – y) + 2y = 950
1050 – 3y + 2y = 950
3y – 2y = 1050 – 950
y = 100
Substitute y = 100 into equation 1
x + 100 = 350
x = 250
Answer: 250 $3 tickets and 100 $2 tickets were sold.

Answers
Answer:
See Below.
Step-by-step explanation:
We want to verify the equation:
[tex]\displaystyle \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}}[/tex]
Recall that tanθ = sinθ / cosθ. Likewise, cotθ = cosθ / sinθ. Then by substitution:
[tex]\displaystyle \begin{aligned} \frac{\tan\theta}{ 1- \cot \theta} + \frac{\cot\theta}{1 - \tan\theta} & = \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \\ \\ & \stackrel{\checkmark}{=} \frac{\dfrac{\sin\theta}{\cos\theta}}{1 - \dfrac{\cos\theta}{\sin\theta}} + \frac{\dfrac{\cos\theta}{\sin\theta}}{1 - \dfrac{\sin\theta}{\cos\theta}} \end{aligned}[/tex]
Hence verified.

during the work week mrs. Jamison drive 75 miles each way to work if she works 21 days each month how far does she drive for the work during the month
Answers
Answer:
See below:
Step-by-step explanation:
So, the question asks how far she drives in a month, this probably includes going to work and coming back. Therefore, each day takes 2 times 75 which is 150!
Now, we know she goes 150 miles each day going to work and coming back. We can now multiply that by 21 to get out answer.
We can split 21 into 10 * 2 + 1 for our convenience.
150 times 10 is 1500 and that times two is 3000 added by 150 is 3150.
Then we get out answer; 3150 miles!
