Rectangle with coordinates: (0, negative 0.5), (1, negative 0.5), (0, negative 3), and (1, negative 3).
OPTION B.
The rectangle with coordinates: (0, 1), (0, 6), (2, 1), and (2, 6) shows the new position of the original rectangle after a translation of 2 units upwards on the y-axis.
Explanation:In mathematics, a translation moves an object without changing its shape or orientation. You simply move it to another position in the plane. To find the new position of the rectangle after a translation, we need to find which set of coordinates matches those of our original rectangle but is located in a different spot.
Looking at the options given, the only rectangle that represents a translation of the original is the rectangle with coordinates: (0, 1), (0, 6), (2, 1), and (2, 6). This rectangle is similar in shape and orientation to our original rectangle, but it is shifted 2 units upwards on the y-axis.

How to transform the preimage and image of a quadrilateral?In Mathematics, a translation is a type of transformation that is typically used for shifting every point of a geometric object in the same direction on the cartesian coordinate, as well as for the same distance.
In this scenario and exercise, we would apply a translation of 2 units to the right and 2 units up to the given rectangle, in order to determine the new position of the rectangle after a translation as follows;
(x, y) → (x + 2, y + 2)
Point (1, 0) → (1 + 2, 0 + 2) = (3, 2).
Point (1, 2) → (1 + 2, 2 + 2) = (3, 4).
Point (6, 0) → (6 + 2, 0 + 2) = (8, 2).

what direction is 45 degrees in clockwise from due east?
A direction of 45 degrees clockwise from due east would put you in the South-East quadrant of a compass or geometric plane.
Explanation:When discussing directions in terms of degrees, it's commonly understood with the idea of a compass rose or a unit circle in mind. Here, 'Due East' is represented as 0 or 360 degrees. A clockwise rotation would mean we are moving in a positive direction.
Therefore, if you start from Due East which is 0 degrees and rotate 45 degrees in the clockwise direction, you would end up in the south-east direction. This is because in the coordinate system, the +x direction is East and moving in the clockwise direction, the next quadrant would be the South-East quadrant. So, 45 degrees clockwise from due east would be considered as South-East direction on a compass rose or geometrically on a plane if you are looking at it in terms of degrees on a circle.

Marianne has been collecting donations for her biscuit stall at the school summer fayre. There are some luxury gift tins of biscuits to be sold at £5 each, normal packets at £1 each, and mini- packs of 2 biscuits at 10p each. She tells Amy that she has received exactly 100 donations in total, with a collective value of £100, and that her stock of £1 packets is very low compared with the other items. Amy wants to work out how many of each item Marianne has. Show how she can do it.
Number of luxury gift tins of biscuits L sold is 18.
Number of mini- packs of 2 biscuits M sold is 80.
Number of normal packets N sold is 2.
Step-by-step explanation:Let L, M, N represent the number of Luxury, Mini, and Normal packets sold.
Total earned by selling luxury gift tins of biscuits = 5L
Total earned by selling normal packets = £1N
Total earned by selling 2 biscuits at 10p = 0.1M
Marianne tells Amy that she has received exactly 100 donations in total:
Equation becomes:
[tex]L+N+M=100[/tex] .... (1)
total earning is £100, so another equation becomes:
[tex]5L+N+0.1M=100[/tex] .......(2)
Given is that stock of £1 packets is very low compared with the other items:
so, N<L and N<M
Putting y = 0 in equation 1 and 2
[tex]L+M=100[/tex] or [tex]L=100-M[/tex] .....(3)
[tex]5L+0.1M=100[/tex] ......(4)
Replacing L by 100-M in the equation 4
[tex]5(100-M)+0.1M=100[/tex]
[tex]500-5M+0.1M=100[/tex]
4.9M=400
M=81.63
As, L=100-M
[tex]L=100-81.63=18.37[/tex]
L=18.37
We can round L and M to 18 and 81 respectively and solve for N from 1 and 2 equations.
[tex]L+M+N=100[/tex]
=>[tex]18+N+81=100[/tex]
=>[tex]N=1[/tex]
[tex]5(18)+N+0.1(81)=100[/tex]
[tex]90+N+8.1=100[/tex]
=> N=1.9
We will repeat the same process with N = 2 and get the following result.
Number of luxury gift tins of biscuits L sold is 18
Number of mini- packs of 2 biscuits M sold is 80
Number of normal packets N sold is 2

Applying the concept:
Given, [tex] BASE\; (B)= \; 74\; cm\\ HEIGHT \;(H)=14.8 \;cm\\\\ Area \; of \; the \; Parallelogram = 74 \; cm \times 14.8 \; cm = 1095.2 \; cm^{2} [/tex]
Find the general solution of the differential equation. (enter your solution as an equation.) (8 + x)y' = 3y
Final answer:
The general solution to the differential equation (8 + x)y' = 3y is y = C(8+x)³, where C is a constant and can be found by integrating and rearranging the separated variables.
Explanation:
To find the general solution of the differential equation (8 + x)y' = 3y, we can separate variables and integrate both sides. First, we divide both sides by (8 + x) and then by y to get [tex]\frac{ y'}{y} = \frac{3}{8 + x}[/tex]
Next, we integrate both sides:
Integrate LHS: [tex]\int \frac{dy}{y} = ln|y| + C_1[/tex]
Integrate RHS: [tex]\int \frac{3dx}{8 + x} = 3ln|8+x| + C_2[/tex]
Now, we can combine the two constants (C₁ and C₂) into a single constant C by writing C = C₂ - C₁. So our solution looks like ln|y| = 3ln|8+x| + C. We can exponentiate both sides to solve for y:
[tex]y = e^{3ln|8+x|+C}[/tex]
Remembering that [tex]e^{ln|a|} = a[/tex], we can simplify this to:
y = C(8+x)³ where C is a constant.
This is the general solution to the differential equation.
a copper alloy that is 40% copper is to be combined with a copper alloy that is 80% copper to produce 120 kilograms of an alloy that is 70% copper. how many kilograms of each alloy must be used? please work it out
After setting up and correcting a system of equations, the student needs to use 30 kg of the 40% copper alloy and 90 kg of the 80% copper alloy to create 120 kg of a 70% copper alloy.
To solve this problem, we need to set up a system of equations. Let x be the amount of 40% copper alloy needed, and y be the amount of 80% copper alloy needed.
First, we have the total weight equation:
x + y = 120 kg (the final alloy's total weight)
Next, we have the copper content equation:
0.40x + 0.80y = 0.70 × 120 kg (the final alloy's copper content)
Now, let's solve this system of equations:
Address the second equation: 40x + 80y = 8400
Express x in terms of y: 40x = 8400 - 80y
Divide by 40: x = 210 - 2y
Substitute x in the first equation: (210 - 2y) + y = 120
Solve: 210 - y = 120, y = 90 kg
Finally, substitute the value of y back into x = 210 - 2y: x = 210 - 2 imes 90 = 210 - 180 = 30 kg
So, we need 30 kg of the 40% copper alloy and 90 kg of the 80% copper alloy.

how can a ratio's number can be changed without changing the ratio itself
The ratio is a fraction that tells us how many times longer a thing is compared to another thing. In mathematics, we express a ratio as the relationship between two numbers, namely [tex]a \ and \ b[/tex], so the ratio can be written as:
[tex]r=\frac{a}{b}[/tex]
If we can change this number without changing the ration we need to multiply both the numerator and the denominator by the same number. For instance, if we have the following ratio:
[tex]r=\frac{2}{3}[/tex]
We can multiply both the numerator and denominator, say, by 7. Then:
[tex]r=\frac{7\times 2}{7 \times 3}=\frac{14}{21}[/tex]
As you can see, the ratio's number has changed but without changing the ratio itself because:
[tex]\frac{2}{3}=\frac{14}{21}[/tex]
