Since the line starts with a closed dot, it resembles ≥ and ≤. We can write an inequality to represent it:
j ≤ -5
This means that all real numbers are solutions to the inequality except the numbers greater than -5.
Since we are using the closed dot, -5 is included as one of the solutions. It also satisfies the inequality we wrote above.
5 ≤ 5
Therefore, the answer is [ True ]
Best of Luck!
The value is 21 Because three represents those to variables which both equal to 21.
The sequence multiplies by 1/3.
Using the formula for a geometric sequence:
a(n) = a(1) * r^(n-1)
So...
a(n) = 648 * (1/3)^(n-1)
Plugging in 8 for n produces:
a(n) = 648 * (1/3)^(7)
Using a calculator, I find the answer to be 0.296296296...
Use the pythagoras theorem
And the answer will be 36.
