(m+2)⁴ = ((m+2)²)²
= (m² + 4+ 2m)²
= m⁴ + 8 + 4m² + 8m² + 16m + 4m³ .........( (a+b+c)² = a²+b²+c²+2ab+2bc+2ac)
= m⁴ + 8 + 12m² + 16m + 4m³
The radius of the circle is given to be r = 14.5
Let the center be O. So OB is the radius = 14.5
We can draw a triangle as shown in the image below. We have a right angled triangle. We know the hypotenuse and the base, we need to find the perpendicular side. This can be done using the Pythagorean theorem.
So, we can write:

Thus, the measure of OA = 10.5
OB = OA + AB
14.5 = 10.5 + AB
⇒
AB = 4
Answer:
The answer to your question is y = 1/2x - 7
Step-by-step explanation:
Data
Point = (0, -7)
line = y = 1/2x + 5
Parallel line have the same slope.
Slope of the first line = 1/2
Slope of the new line = 1/2
Equation of the line
y - y1 = m(x - x1)
Substitution
y + 7 = 1/2(x + 0)
Simplification
y + 7 = 1/2x
result
y = 1/2x - 7
The graph of the line segment PQ is attached. To find the length, we have to use distance formula which is



To find the midpoint,we have to use the formula
