Answer:
First choice
Step-by-step explanation:
The difference quotient in general is
. To get an expression for
, replace x with x + h.
For this question,

Factor
out of the numerator.

Answer:
Solution set = {25}
Step-by-step explanation:
=> 
Dividing both sides by -1
=> 
Taking square on both sides
=> x = 25
<em><u>Solution set = {25}</u></em>
Answer:
8 is a positive number.
Step-by-step explanation:
If Hannah gives her younger sister 3 shirts, it does not matter what order she hands them to her. No matter the order, it will still be the same group of 3 shirt. Since order is not important this problem can be solved using a combination.
Specifically, we are asked to find 8C3 (sometimes called "8 choose 3"). This is a fraction. In the numerator, we start with 8 and count down 3 numbers. In the denominator, we start with 3 and count all the way down to 1.
your answer is 56
Answer:
a₆ ≈ 25.284
Step-by-step explanation:
There is a common ratio between consecutive terms , that is
8 ÷ 6 =
÷ 8 = 
This indicates the sequence is geometric with nth term
= a₁ 
where a₁ is the first term and r the common ratio
Here a₁ = 6 and r =
, then
a₆ = 6 ×
= 6 ×
=
≈ 25.284 ( to the nearest thousandth )
