Answer: Answer is 3241 gm or 3.2 kg approx.
Step-by-step explanation:
Weight of the brick( in kg) =22 kg
Weight of the brick in gm= 22*1000 gm (1 kg = 1000gm)
= 22000 gm
Weight of bricks removed = 18759 gm
Weight of bricks left in the pile= 22000-18759gm
=3241 gm or 3.2 kg approx
Hence, the weight of the bricks left is 3.2 kg approx.

The code will have a SyntaxError.
What type of error will the following code have?The line cat "Fluffy" = is a syntax error because the variable cat is not defined using the correct Python syntax.
In Python, you must define a variable before you can assign a value to it. The correct way to write this line of code would be:
cat = "Fluffy"
The line dog == "Ducky": print("x is 10") is also a syntax error because the variable dog is not defined. The correct way to write this line of code would be:
dog = "Ducky"
if cat == "Fluffy" and dog == "Ducky":
print("x is 10")

Curved surface area of cylinder (\(2\pi rh\)):
2\(\pi\)×1×13 = 26\(\pi\) m²
Curved surface area of cone (\(\pi rl\), where \(l\) is the slant height):
Use Pythagoras for slant height: \(\sqrt{2^2 + 1^2}\) = \(\sqrt{5}\)
\(\pi\)×1×\(\sqrt{5}\) = \(\pi \sqrt{5}\) m²
Total:
\(\pi\) + 26\(\pi\) + \(\pi \sqrt{5}\) = 91.8 m²
a rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. 400 feet of fencing is used. find the dimensions of the playground that maximize the total enclosed area
The dimensions of the playground that maximize the total enclosed area is 100 feet.
Let,
L= length of entire playground
W = width of entire playground
Assume the dividing fence is parallel to the width.
Total fencing required
2L + 3W = 400
L= (400 − 3W)2
Area of entire playground,
A= L × W
= (400−3W)/2⋅W
= −3/2W^2 + 200W
Maximum area will occur at a point where the derivative of the area is equal to zero.
dA/dW = −3W+ 200 = 0
W = 66 2/3
Substituting 91 1/3 for W in 2L + 3W = 400

Solve the differential equation. (Use C for any needed constant. Your response should be in the form 'g(y)=f(theta)'.) 3 dy dtheta = ey sin2(theta) y sec(theta)
The solution to the given differential equation is: |y| = D|sec(theta) + tan(theta)| which is solved using integration and then separating both the variables.
To solve the given differential equation, we'll start by separating the variables and integrating both sides.
First, we'll move all terms involving y and dy to one side and terms involving theta and dtheta to the other side:
3dy = ey sin^2(theta) y sec(theta) dtheta
Next, we'll divide both sides by y and sin^2(theta) to isolate the terms involving y on the left side:
3/y dy = e sec(theta) dtheta
Now, we can integrate both sides:
∫(3/y) dy = ∫(e sec(theta)) dtheta
The integral of 3/y with respect to y is ln|y| + C1, where C1 is the constant of integration.
The integral of e sec(theta) with respect to theta is ln|sec(theta) + tan(theta)| + C2, where C2 is the constant of integration.
Therefore, the general solution to the differential equation is:
ln|y| + C1 = ln|sec(theta) + tan(theta)| + C2
We can combine the constants of integration, C1 and C2, into a single constant, C:
ln|y| = ln|sec(theta) + tan(theta)| + C
Finally, by taking the exponential of both sides, we can eliminate the natural logarithm:
|y| = e^(ln|sec(theta) + tan(theta)| + C)
Since e^C is just a constant, we can replace it with a new constant, D:
|y| = D|sec(theta) + tan(theta)|

Answer:
• Equations
\(y=x+2\)\(y=x^2\)• Solutions (2, 4) and (–1, 1)
Explanation
System of equations
• Linear equation
\(y=x+2\)• Quadratic equation
\(y=x^2\)We have to set both equations to 0 and equalize them:
• 1. Setting them to 0:
\(0=x+2\)\(0=x^2\)• 2. Equalizing them:
\(x+2=x^2\)To solve the system using the General Quadratic Formula, we have to set the equation in the form ax² + bx+ c = 0:
\(x^2-x-2=0\)Thus, in this case a = 1, b = -1 and c = -2. Using the formula:
\(x_{1,2}=\frac{-(-1)\pm\sqrt{(-1)^2-4(1)(-2)}}{2(1)}\)\(x_{1,2}=\frac{1\pm\sqrt{1+8}}{2}\)\(x_{1,2}=\frac{1\pm\sqrt{9}}{2}\)Finding both solutions:
\(x_1=\frac{1+3}{2}=\frac{4}{2}=2\)\(x_2=\frac{1-3}{2}=\frac{-2}{2}=-1\)Finally, replacing these values in the linear equation to find y:
\(y_1=2+2=4\)\(y_2=-1+2=1\)Therefore, the solutions are (2, 4) and (–1, 1).

Which plot matches the description
Based on Kamila's description, the dot plot that matches her description is Dot plot 1.
The presence of an outlier and the right-skewed distribution can be inferred from the high frequency of data points on the left side of the plot and the single data point that is much larger than the others on the right side.
What is frequency of dot plot?
The frequency in a dot plot refers to the number of dots or data points that appear in a particular bin or category. In a dot plot, each dot typically represents one data point, and the frequency of the dot is the number of data points that have that value. For example, if a dot plot shows the heights of students in a class, with bins for each inch, then the frequency of a particular bin would be the number of students whose height falls within that bin. The frequency can be represented by the number of dots in that bin or by a numerical value.

The interval containing the values of k for which the curves to not cross nor touch is given as follows:
0 < k < 3.
Discriminant and number of solutionsThe two functions in the context of this problem are defined as follows:
y = k(2x - 1).y = x² + 2x + 1.The functions will not cross neither touch if the following quadratic equation has no solutions, that is:
x² + 2x + 1 = 2kx - k.
x² + (2 - 2k)x + 1 + k = 0.
The coefficients of the quadratic equation are given as follows:
a = 1, b = 2 - 2k, c = 1 + k.
The discriminant is calculated as follows:
Δ = b² - 4ac
Δ = (2 - 2k)² - 4(1)(1 + k)
Δ = 4k² - 8k + 4 - 4 - 4k
Δ = 4k² - 12k
The roots of the discriminant are as follows:
4k² - 12k = 0
4k(k - 3) = 0
k = 0, k = 3.
The equation has no solution if the discriminant is negative. A concave up quadratic equation is negative between it's roots, hence the interval is:

I set z=t=0(x,y,z,t)
and I got a partial solution (0,1,0,0).
I solved two homogeneous matrices once for z=1
and t=0
, then for z=0
and t=1
and I got two solutions (1,1,1,0)
and (1,1,0,1).
Then, I got (0,1,0,0)+a∗(1,1,1,0)+b∗(1,1,0,1
)
Therefore, all possible results are (0,1,0,0),(1,0,1,0),(1,0,0,1),(0,1,1,1)
Would this be correct?
The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).
Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.
Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).
Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).
Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).
To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.
(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)
Expanding this expression, you get:
(0+a+b, 1+a+b, 0+a, 0+b)
Simplifying, you obtain the following set of solutions:
(0, 1, 0, 0)
(1, 2, 1, 0)
(1, 2, 0, 1)
Therefore, the correct set of possible results would be:
(0, 1, 0, 0)
(1, 2, 1, 0)
(1, 2, 0, 1)
Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

Step-by-step explanation:
Vanessa has $200 in her savings account and
just received $30 for her birthday. She intends
to spend all of her money on coffee. She spends
$3.50 on coffee every day. Write an equation
that can be used to find the amount of money she
has left after x days.
Answer:
y = -3.5x + 230
Step-by-step explanation:
Find how much money she has now:
200 + 30 = $230
To create an equation to find how much money she has left, let y represent the amount of money left, and x represent the number of days.
Coffee will cost $3.50 every day, so 3.5x will represent all of the money that she will spend on coffee.
The amount of money she has left will be represented by 230 - 3.5x.
Rearrange this to put x in front, and let this equal to y to create the equation:
y = -3.5x + 230
So, the equation that can be used to find how much money she has left is y = -3.5x + 230

The period of the given degree-4 LFSR with the polynomial p(x) = x^4 + x^2 + 1 and the seed (s3, s2, s1, s0) = 0110 is 15.
A Linear Feedback Shift Register (LFSR) is a deterministic algorithm that generates a pseudo-random sequence of numbers based on a polynomial function and an initial seed. The period of an LFSR is the length of the generated sequence before it repeats itself. In this case, the polynomial is p(x) = x^4 + x^2 + 1, and the seed is (s3, s2, s1, s0) = 0110. To find the period, we iterate through the LFSR sequence and count the steps until the seed is repeated. In this specific case, after iterating 15 times, the seed (0110) is repeated.
Thus, given the degree-4 LFSR with polynomial p(x) = x^4 + x^2 + 1 and seed (s3, s2, s1, s0) = 0110, the period of the generated sequence is 15.
