4. If p is true and q is true, then ~ p -> ~ q is always true.
5. If p -> q is true and q is true, then p is always true.
Further Explanation:
The logic gates are used here.
Here, the symbol -> is for implication. Implication p-> q means that if p is true then q must be true.
So let us look at all the questions one by one.
1. If p is true and q is false, the p -> q is always, sometimes, never true.
p -> q
true -> false
The true should imply true so the given statement will never be true.
2. When p is false and q is true, then p or q is always, sometimes, never true.
false or true
We know that in or gate even if one input is true, the whole output is true. So this statement will be always true given p is false and q is true.
3. If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.
This translates to:
true -> true
So it will never be false.
4. If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.
This translates to:
false -> false
This will always be true.
5. If p -> q is true and q is true, then p is always, sometimes, never true.
If p->q is true and q is true then p will always be true. "Implies to" states that in p->q, in order for q to be true p has to be true. So p will always be true.

jessie uses 20 liters of gasoline to travel 200kilometers, how many liters of gasoline will he use on a trip of 700 kilometer?
Answer: He will use 70 liters of gasoline on a trip of 700 kilometer.
Step-by-step explanation:
Given : Jessie uses 20 liters of gasoline to travel 200 kilometers.
We assume that the rate of consumption of gasoline is contant.
By UNITARY METHOD, the amount of gasoline required for 1 kilometer distance = [tex]\dfrac{20}{200}=\dfrac{1}{10}[/tex] liter
Now, the amount of gasoline required for 700 kilometer distance = [tex]700\times\dfrac{1}{10}=70[/tex] liters
Hence, He will use 70 liters of gasoline on a trip of 700 kilometer.
To calculate how many liters of gasoline Jessie will use for a 700 km trip, the fuel efficiency is first determined to be 10 km/L from the given data. Using this information, it is found that Jessie will need 70 liters of gasoline for the 700 km trip.
Jessie uses 20 liters of gasoline to travel 200 kilometers. To determine how much gasoline Jessie will use on a trip of 700 kilometers, we first need to find the fuel efficiency of the vehicle. By dividing the distance traveled by the amount of gasoline used, we get the fuel consumption rate:
Fuel efficiency = Distance / Gasoline
Fuel efficiency = 200 km / 20 L
Fuel efficiency = 10 km/L
Now we know that the vehicle uses one liter of gasoline to travel 10 kilometers. To find out how many liters are needed for a 700 km trip, we apply the following:
Gasoline needed = Trip distance / Fuel efficiency
Gasoline needed = 700 km / (10 km/L)
Gasoline needed = 70 liters
Therefore, Jessie will use 70 liters of gasoline to travel 700 kilometers.

Write an equation to represent the value of his stamp collection in terms of the number of stamps, s, that he had originally, and find the value of s.
Tony misplaced 7 stamps
Each stamp worth = $0.15
Total value of stamp now = $5.55
Let the number of stamps be 's'
Number of stamps now = s - 7 (misplaced 7 stamps)
price (number of stamps now ) = 0.55
0.15 (s - 7) = 5.55
Divide by 0.15 on both sides
s - 7 = 37
Add 7 on both sides
s = 44
Total number of stamps originally he had = 44 stamps

Part 1: Mr. Nicholson accepts a job that pays an annual salary of $60,000. In his employment contract, he is given the option of choosing a) an annual raise of $3,500 or b) an annual raise of 5% of his current salary.
Procedures:
1. Use the provided information to identify each of Mr. Nicholson's earning opportunities as arithmetic or geometric. For each opportunity, include all the common difference or ratio.
2. Model each of Mr. Nicholson's salary options with a recursive model that includes his potential earnings for the first three years of employment.
a. $60,000 salary with an annual raise of $3,500
b. $60,000 salary with an annual raise of 5% of his current salary
3. Suppose Mr. Nicholson plans on working for his new employer for at least 9 years. use each of the recursive models to determine Mr. Nicholson plans on working for his new employer for at least 9 years. Use each of the recursive models to determine Mr. Nicho
Answer:
See belowStep-by-step explanation:
1. Arithmetic: Add 3,500
The annual raise of 3,500 means add 3,500 to the previous year's salary
60,000 + 3,500 = 63,500
63,500 + 3,500 = 67,000
67,000 + 3,500 = 70,500
70,500 + 3,500 = 74,000
74,000 + 3,500 = 77,500
Geometric: Multiply by 1.05
The annual raise by 5% of his current salary means multiply by 1.05.
60,000 x 1.05 = 63,000
63,000 x 1.05 = 66,150
66,150 x 1.05 = 69,457.50
69,457.50 x 1.05 = 72,930.38 rounded
72,930.375 x 1.05 = 76,576.89
The first sequence is arithmetic because we add the same number (3,500) to the preceding term. The second sequence is geometric because we multiply the preceding term by the same number always (1.05.)
2a. Arithmetic - New salary is $3,500 greater each year than last year's salary
S = 60,000 + 3500(n-1)
Geometric - New salary is 5% more each year than last year's salary
60,000 + (1.05)^(n-1)
2b. Arithmetic Earnings over 3 years
60,000 + 63,500 + 67,000 = 190,500
Geometric Earnings over 3 years
60,000 + 63,000 + 66,150 = 189,150
There is a 1,000 dollar difference. In this case, the arithmetic increase of 3,500 dollars would be better for Mr. Nicholson. 1,000 dollars may or may not be considered a big difference. In my opinion, I'd say there is a slight difference between the two
3.Arithmetic
a(9) = 3,500 + a(9-1)
a(9) = 3,500 + 89,000
a(9) = 92,500
Geometric
a(9) = 1.05 x a(9-1)
a(9) = 1.05 x 84,425.90
a(9) = 88,647.20
4. In this case, both the 3 year and 9 year time frames favor the arithmetic increase of $3,500. At 3 years, he would have 190,500 compared to the geometric salary of 189,150. However, this is a small difference. If he is going to be at the company for 9 years, then definitely he should choose the first opportunity. 92,500 is significantly more money than 88,647.20. So, longer time frames only make the first opportunity, which is better to begin with, shine even more.
I'm always happy to help :)
The problem analyses two salary options: a regular increase (arithmetic sequence) and a percentage increase (geometric sequence). It involves using recursive models to calculate potential earnings over a specified period. Over the long term, the geometric sequence provides a greater total income.
Explanation:The subject is about Mr. Nicholson's two different salary options. An arithmetic sequence series represents option a) where Mr. Nicholson's salary increases by a steady $3,500 per year. The difference, or increase, remains constant.
On the other hand, option b) represents a geometric sequence where Mr. Nicholson's salary increases by 5% of his current salary each year. The ratio, or multiplier remains constant at 1.05 (current salary * 5%).
To calculate his earnings for the first three years using the recursive model: Option a) Year 1: $60,000 Year 2: 60,000 + 3,500 = $63,500, Year 3: 63,500 + 3,500 = $67,000. Option b) Year 1: $60,000, Year 2: 60,000 * 1.05 = $63,000, Year 3: 63,000 * 1.05 = $66,150.
For a period of 9 years, continually apply the recursive model for each year. It becomes apparent that with the geometric sequence (option b), the amount of raise will increase per year because it is based on a percentage of his increasing salary, providing a higher total over time compared to the arithmetic sequence (option a).

The coordinate of A
[tex]x=\frac{0+2}{2}[/tex], [tex]y=\frac{0+6}{2}[/tex]
[tex]x_1=0,x_2=2,y_1=6,y_2=0[/tex]
[tex]x=1,y=3[/tex]
The coordinates of A is (1,3).
The coordinates of mid point B
[tex]x=\frac{0+8}{2},y=\frac{0+6}{2}[/tex]
[tex]x_1=0,y_1=6,x_2=8,y_2=0[/tex]
[tex]x=4,y=3[/tex]
The coordinates of midpoint B is (4,3).
Therefore, the end points of midsegement for triangle RST are (1,3) and(4,3) which is parallel.
