Suppose that P(n) is a propositional function. Determine for which nonnegative integers n the statement P(n) must be true if a) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 2) is true. b) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 3) is true. c) P(0) and P(1) are true; for all nonnegative integers n, if P(n) and P(n 1) are true, then P(n 2) is true. d) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n 2) and P(n 3) are true

Answers

Answer 1

Solution :

a). [tex]$P(0)$[/tex] is true

Then ,[tex]$P(0+2)=P(2)$[/tex] is true.

         [tex]$P(2+2)=P(4)$[/tex] is true

          [tex]$P(4+2)=P(6)$[/tex] is true.

Therefore, we see that [tex]$P(n)$[/tex] is true for all the even integers : [tex]$\{0, 2,4,6,...\}$[/tex]

b). [tex]$P(0)$[/tex] is true

Then ,[tex]$P(0+3)=P(3)$[/tex] is true.

         [tex]$P(3+3)=P(6)$[/tex] is true

          [tex]$P(6+3)=P(9)$[/tex] is true.

Therefore, we see that [tex]$P(n)$[/tex] is true for all the multiples of 3 : [tex]$\{0, 3,6,9,12,...\}$[/tex]

c). [tex]$P(0)$[/tex] and [tex]$P(1)$[/tex] is true, then [tex]$P(0+2)=P(2)$[/tex] is true

[tex]$P(1)$[/tex] and [tex]$P(2)$[/tex] is true, then [tex]$P(1+2)=P(3)$[/tex] is true.

[tex]$P(2)$[/tex] and [tex]$P(3)$[/tex] is true, then [tex]$P(2+2)=P(4)$[/tex] is true.

So, we observe that  [tex]$P(n)$[/tex] is true for all the non- negative integers : [tex]$\{0, 1,2,3,4,5,6,...\}$[/tex].

d). [tex]$P(0)$[/tex] is true,

   So, [tex]$P(0+2)$[/tex] and [tex]$P(0+3)$[/tex] is true or [tex]$P(2)$[/tex] and [tex]$P(3)$[/tex] is true.

   Now,   [tex]$P(2)$[/tex] is true.

Again, [tex]$P(2+2)$[/tex] and [tex]$P(2+3)$[/tex] is true or [tex]$P(4)$[/tex] and [tex]$P(5)$[/tex] is true.

   Now, [tex]$P(3)$[/tex] is true.

Again, [tex]$P(3+2)$[/tex] and [tex]$P(3+3)$[/tex] is true or [tex]$P(5)$[/tex] and [tex]$P(6)$[/tex] is true.

Thus,

[tex]$P(n)$[/tex] is true for all the non- negative integers except 1 : [tex]$\{0, 2,3,4,5,6,...\}$[/tex].

Step-by-step explanation:

The absolute value function negates its argument when its argument is negative. The expression 3x+12 will be negative when ...

  3x +12 < 0

  x +4 < 0

  x < -4 . . . . . makes the absolute value function change its argument's sign

2) The difference of nine times a number y and eighteen
3) Half a number n increased by four times the number
4) Twice the sum of a number w cubed and twenty-three

Answers

Answer:

             1)   7x - 5              2)   9y - 18              3)   0.5n + 4n              4)  2(w³+23) Step-by-step explanation:

1)

The product of seven and a number x:   7·x = 7x

Five less than the product of seven and a number x:

7x - 5

2)

nine times a number y:  9·y = 9y

The difference of nine times a number y and eighteen:

9y - 18

3)

half a number n:   0.5n

four times the number:   4·n = 4n

Half a number n increased by four times the number:

0.5n + 4n

4)

a number w cubed:  

the sum of a number w cubed and twenty-three:  w³+23

Twice the sum of a number w cubed and twenty-three:

2(w³+23)

The measure of an angle is 39°. What is the measure of its complementary angle?

Answers

Answer:

51 degrees

Step-by-step explanation:

Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).

90 - 39 = 51

Answer:

51°

Step-by-step explanation:

Complementary angles add to 90°.

If one of them is 39°, then the other is:

90° - 39° = 51°

If the sequence 4, 8, 12, 16 continues, what will be the 7th
term?

Answers

Answer:

28

Step-by-step explanation:

In order to find the seventh term in this arithmetic function, you need to find its function; in order to do this, you must first identify the common difference by finding the difference between two consecutive terms:

16 - 12 = 4; the common difference is 4

Now, you need to find the 0th term, which is the 1st term minus the common difference:

4 - 4 = 0

At this point, you can write out the function (where f(n) = [0th term] + [common difference]n:

f(n) = 4n

Finally, you can plug 7 into this function:

f(n) = 4(7)

f(n) = 28, so the 7th term is 28

Answers

Answer:

A square has all sides congruent. SIDE A, B, C and D would be congruent in size to one another, and the angles would also be equal to one another. However, most any polygon can be drawn with all sides and angles equal. For instance, an equilateral triangle has all sides and all angles equal, and that is the definition of a polygon. Polygons with more sides are described as "regular" e.g., a stop sign or an equilateral octagon is also a shape that has all sides congruent. A rectangle, however, would not, since only two sides would be congruent to one another.

You are making lemonade. The amount of sugar you need depends on the amount of lemonade mix you use. Cups of sugar

1/3

3

Packets of lemonade mix

1

Is the amount of sugar you need proportional to the amount of lemonade mix you use?

Cups of sugar ∝ Number of packets

C ∝ N

C = k/N

k = C/N

a) For

1/3 cups of sugar and 1 packet of Lemonade mix

1/3 ∝ 1

1/3 = 1k

k = 1/3/1

k = 1/3

b) For

1 cups of sugar and 3 packets of Lemonade mix

1 ∝ 3

1 = 3k

k = 1/3

k = 1/3

c) For

3 cups of sugar and 9 packets of Lemonade mix

3 ∝ 9

3= 9k

k = 3/9

k = 1/3

Therefore, Yes, the amount of sugar you need proportional to the amount of lemonade mix you use. This is because the value is k is the same
