Answer:
<h2>The standard form: x² + (y + 1)² = 25</h2><h2>The general form: x² + y² + 2y - 24 = 0</h2>Step-by-step explanation:
The equation of a circle:
(h, k) - center
r - radius
We have the center (0, -1) and the radius r = 5 <em>(look at the picture)</em>.
Substitute:
<em>use (a + b)² = a² + 2ab + b²</em>
<em>subtract 25 from both sides</em>
Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence
where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is

Solving the inequality we get
Step-by-step explanation:
We need to find the value of x from the inequality
Solving:
Subtract 8 on both sides:
Divide both sides by (-1). For doing this the sign of inequality is reversed i.e, > is changed into <
So, Solving the inequality we get
