If the series is
then it is geometric, which we know converges as long as the base is smaller than 1 in absolute value, i.e.
. "Expanding" the absolute value, this is equivalent to
When
is in this interval, the geometric sum converges to
-7x ≥ 56.
Divide both sides by -7, and the inequality sign reverses, because we are dividing by a negative number.
The sign also reverses when you multiply both sides of inequality by a negative number.
-7x/-7 ≤ 56/-7
x ≤ -8
The answer is the first option.
<span>{x | x ≤ -8}
</span>
This simply means x, such that x is less than or equal to -8.
I hope this helped.
Y=(x/2)+7 as an equation if that is what you are asking
Answer:
153.94
Step-by-step explanation:
The formula for area is pi*radius^2
the radius is 7, so we do pi7^2 which is 49pi
49pi is 153.93804 which is 153.94 rounded to two decimal places
Answer:
<u>The correct answer is 2. a = 1/2, b = - 3, c = -2</u>
Step-by-step explanation:
1. Let's review the information provided for an answering the question correctly:
0 =1/2x^2- 3x- 2
0 = 1/2x² - 3x - 2
2. Let's find the values for a, b and c.
According to the quadratic equation, we have:
a = 1/2
b = - 3
c = - 2
<u>The correct answer is 2. a = 1/2, b = - 3, c = -2</u>
