Answers
Answer:
16x^2 + 24x + 9
Step-by-step explanation:
perfect square trinomial is of the form
a^2 + 2 * a * b + b^2
9x^2 + 9x + 1 = (3x)^2 + 3*3x*1 + 1^2 not a perfect square trinomial
36b^2 − 24b + 8 = ( 6b)^2 -2 * 6b *2 + ( 2 sqrt(2)) ^2 not a perfect square trinomial
16x^2 + 24x + 9 = ( 4x) ^2 + 2 * ( 4x) * 3 + 3^2 = perfect square trinomial
4a^2 − 10a + 25 = ( 2a) ^2 - 1 * 2a *5 + 5^2 not a perfect square trinomial

If p is true and ~ q is false, then p -> ~ q is always, sometimes, never false.
If p is true and q is true, then ~ p -> ~ q is always, sometimes, never true.
If p -> q is true and q is true, then p always, sometimes, never is
Answers
1. If p is true and q is false, the p -> q is never true.
2. When p is false and q is true, then p or q is always true.
3. If p is true and ~ q is false, then p -> ~ q is never false.
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.

Answer:
1) 15 feet per second
2) distance after 3 seconds 45 feet
3) slower
Step-by-step explanation:
1) 30/2 = 15
2) 15 x 3
3) 55/4 = 13.75 < 15
Final answer:
The scooter travels 15 feet after 1 second, 45 feet after 3 seconds, 60 feet after 4 seconds, and 75 feet after 5 seconds. The speed of the scooter is 15 feet per second. The skateboard is going slower than the scooter.
Explanation:
To complete the double number line, we need to determine the distance the scooter travels after 1, 3, 4, and 5 seconds. Since the scooter travels 30 feet in 2 seconds at a constant speed, we can determine the distance for each time by finding the proportion:
After 1 second: 30 feet / 2 seconds = 15 feet
After 3 seconds: 30 feet / 2 seconds * 3 seconds = 45 feet
After 4 seconds: 30 feet / 2 seconds * 4 seconds = 60 feet
After 5 seconds: 30 feet / 2 seconds * 5 seconds = 75 feet
The speed of the scooter is the same as its constant speed, which is 30 feet / 2 seconds = 15 feet per second.
The distance the scooter travels after 3 seconds is 45 feet.
Since the scooter traveled 30 feet in 2 seconds, and the skateboard traveled 55 feet in 4 seconds, we can compare their speeds. The scooter traveled 30 feet in 2 seconds, which means its speed is 30 feet / 2 seconds = 15 feet per second. The skateboard traveled 55 feet in 4 seconds, so its speed is 55 feet / 4 seconds = 13.75 feet per second. Therefore, the skateboard is going slower than the scooter.

Which expression gives the number in the nth position in the sequence?
A) 2n - 2
B) 3n + 4
C) 4n - 1
D) 5n
Answers
Answer:
Option B is correct
3n+4[/tex]
Step-by-step explanation:
The nth term for the arithmetic sequence is given by:
....[1]
where,
is the nth position
n is the number of term
is the first term and
d is the common difference.
Given the table:
Position(n) Value of Term()
1 7
2 10
3 13
4 16
5 19
6 22
from the given table:
At n = 1 ,
At n = 2
at n = 3
and so on
Common difference(d) for the sequence is 3
Since,
⇒
Substitute d = 3 and in [1] we have;
⇒
⇒
Therefore, the expression gives the number in the nth position in the sequence is,
3(3)+4
