AB and CD are parallel lines and EH is a transversal.
What is the size of angle AFG?
The value of the consecutive interior angles formed by the parallel lines is : ∠CGF = 61°
Define the term co-interior angles?The two angles which it are on the same side of both the transversal are known as co-interior angles as well as consecutive interior angles. The inside angles total 180 degrees and are known as co-interior angles. It indicates that two internal angles that reside on the same sides of the transversal have a sum that is additional.For the stated question:
∠HGD = ∠CGF = 119° (vertically opposite angles)
And,
∠AFG + ∠CGF = 180° (consecutive interior angles)
∠CGF = 180° - 119°
∠CGF = 61°
Thus, the value of the consecutive interior angles formed by the parallel lines is : ∠CGF = 61°

what is the maximum length of instruction for 8086 based-ibm pc?
The maximum length of an instruction for the 8086-based IBM PC is 15 bytes.
The 8086 microprocessor was used in the original IBM PC and was capable of executing instructions up to 15 bytes in length. The instruction length is determined by the number of bytes needed to encode the operation code, the addressing mode, and any operands.
The maximum length of 15 bytes allows for complex instructions that can perform multiple operations in a single instruction cycle, increasing the efficiency of the processor. However, not all instructions require the full 15 bytes, and many are much shorter, so the average instruction length is typically much less than 15 bytes.

As per the given data:
An engineer designs an improved light bulb.
The previous design had an average lifetime of 1200 hours.
The new bulb had a lifetime of 1201 hours, using a sample of 2000 bulbs.
Let us assume the null and alternative hypothesis
Null: The average lifespan of old and new designs is the same.
Alternative: The lifespans of new and ancient designs differ.
Because of the huge sample size, the p-value is lower. Reject the null hypothesis as a result, and the effect is now considered statistically significant.
Although the difference between 1200 hours and 1201 hours is quite tiny, the effect was statistically significant because of the high sample size.

y =
y =
x + 5
y=x+5
y = -x +5
Answer:
5x - 4y = -20
y = x + 5
y = -x + 5
Step-by-step explanation:
The formula for slope-intercept form is y = mx + b, with b being the y-int.
If the equation does not have an x, y, or b, it is not a slope-intercept form.
5x - 4y = -20 (can be rearranged to y = 5/4x + 5)
y = 1, x = 5/4, b = 5
y = x + 5y
x = 1, y = 1, b = 5
y = -x + 5
x = -1, y = 1, b = 5.

The value of the given limit (at x =1) f(x)=18.
An output value that a function approaches for the specified input values is referred to as a limit. Calculus and mathematical analysis depend on limits, which are also used to determine integrals, derivatives, and continuity. It is employed in the analysis process and constantly considers how the function will behave at a specific point.
A function may approach two different limits. One where the variable approaches its limit through values larger than the limit and the other where the variable approaches its limit through values smaller than the limit. In such a case, the limit is not defined but the right and left-hand limits exist.

what is the eigenvalue for the eigenfunction cosθ of the operator 1sinθddθ(sinθddθ) ?
The eigenvalue for the eigenfunction cosθ of the operator 1sinθddθ(sinθddθ) is -1.
The eigenvalue for the eigenfunction cosθ of the operator 1sinθddθ(sinθddθ) can be calculated by using the formula:
λ = 1/sinθ (d/dθ cosθ)
This formula states that the eigenvalue is equal to the inverse of the sine of θ multiplied by the derivative of the eigenfunction cosθ with respect to θ.
To calculate the eigenvalue, we first take the derivative of the eigenfunction cosθ with respect to θ, which is -sinθ. Then, we multiply this value by the inverse of the sine of θ. This gives us an eigenvalue of -1.
In summary, the eigenvalue for the eigenfunction cosθ of the operator 1sinθddθ(sinθddθ) is -1. This can be calculated by taking the derivative of the eigenfunction and multiplying it by the inverse of the sine of θ.

The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is equal to____(mm)^2
Answer:
150.72
Step-by-step explanation:
area of a cylinder = top circle + bottom circle + lateral
lateral = perimeter of the circle * height = 2π*2 * 10 =40π
area of a circle = πr² = 4π
top & bottom =8π
total = 40π+8π =48π = 150.72
The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is [tex]$$150.8 \mathrm{~cm}^2$$[/tex].
What is the surface area of a solid cylinder?The sum of the areas of all the faces or surfaces that surround a solid results in its total surface area. The tops and bottoms (bases) as well as the remaining surfaces make up the faces. The surface area of a solid without its bases is known as its lateral surface area.
The area of the cylinder is determined by adding the areas of the curving surface and its two circular bases.
A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².
Total surface area [tex]$S=2 \pi r h+2 \pi r^2$[/tex]
Substitute the values in the above equation, we get
[tex]$$\Rightarrow \mathrm{S}=2 \pi \mathrm{r}(\mathrm{r}+\mathrm{h})=2 \times 3.1416 \times 2 \times 12$$[/tex]
simplifying the equation, we get

the top and bottom margins of a poster are 8 cm and the side margins are each 10 cm. if the area of printed material on the poster is fixed at 762 square centimeters, find the dimensions of the poster with the smallest area.
The total area of the poster would actually be 792 square cm, which includes the area of the margins (36 square cm) and the area of the printed material (756 square cm)
To find the smallest area of the poster, we need to determine the size of the poster such that the printed material takes up the maximum amount of space, while still satisfying the margin constraints. Here's the detailed explanation and calculation:
The area of the top and bottom margins is 8 cm × poster width = 8 cm × w.
The area of the side margins is 10 cm × poster height = 10 cm × h.
Total area of the margins = 2 × (8 cm × w) + 2 × (10 cm × h) = 36 cm.
Available space for the printed material = 762 cm - 36 cm = 726 cm.
The optimal dimensions of the printed material would be the closest pair of factors of 726 that add up to 36, which are 18 and 42 cm.
The area of the printed material would be 18 cm × 42 cm = 756 cm.
The total area of the poster = 756 cm + 36 cm = 792 cm.
Therefore, the dimensions of the poster with the smallest area are 756 cm and the total area of the poster is 792 square cm.

sam takes out a loan of R 1 2000 for a year .if the rate is 12% per annum ,how much interest will he pay
Answer:
R 1440
Step-by-step explanation:
Given:-
Principal Amount = R 12000
Time = 1 year
Rate = 12% pa
The Interest can be calculated using the following formula:-
Interest = (Principal Amount * Rate * Time) / 100
Substituting the respective values:-
Interest = (12000 * 12 * 1) / 100
Interest = 144000 / 100
Interest = R 1440
So, Sam will pay an interest of R 1440
you and your roomate are hosting a party, you invited 20 other pair of roommate, during the party you pull everyone at the party excluding yourself and ask everyone how mnya hnads each person shook, 2 condition each person did not shake his roomates hands each person shook a different number of hands how many hands did my roommate shake?
Your roommate shook 10 hands at the party you and your roommate hosted.
If each person at the party shakes hands with a different number of people, and each person did not shake hands with their own roommate, then the number of hands each person shakes will form a set of integers from 0 to 19, with no duplicates. Since there are 20 people at the party, the sum of the numbers from 0 to 19 is 20 * 19 / 2 = 190.
If we subtract the number of hands that each person shakes from this sum, we find that the number of hands that my roommate shook is equal to 190 - (0 + 1 + 2 + ... + 19) = 190 - (0 + 19) * 20 / 2 = 190 - 20 * (19 / 2) = 190 - 20 * 9.5 = 190 - 190 = 0. This is not possible, since each person must shake at least one hand. The only possible answer is 10, which satisfies the conditions.
