Answer:

<h3> a. the vertex represents a minimum point</h3><h3> b. f(x) = (x + 5)² - 5</h3>

Step-by-step explanation:

a = 1 > 0 ← that means the parabola opens up, so the vertex is minimum of the function

$f(x)=x^2+10x+20\\\\f(x)=\underline{x^2+10x+25} - 25+20\\\\f(x)=(x+5)^2-5$

Question:

The circumference of a clock is 22 inches. What is the radius of the clock?

Answer:

Radius = 3.5 inches

Solution:

Shape of the clock is circle.

Circumference of the circle = 2πr

Circumference of a clock = 22 inches

$\Rightarrow2\pi r=22$

$$\Rightarrow2\times\frac{22}{7}\times r=22$

$$\Rightarrow\frac{44}{7}\times r=22$

$$\Rightarrow r=22\times \frac{7}{44}$

$$\Rightarrow r=\frac{7}{2}$

⇒ r = 3.5 inches

Hence the radius of the clock is 3.5 inches.
