Answer: the circumference of the yellow circle is 43.96 ft

Step-by-step explanation:

The perimeter of a plane shape is the total distance around the shape. The circumference of a circle is the same as its perimeter.

The formula for determining the circumference of a circle is expressed as

Circumference = 2πr

Where

π is a constant whose value is 3.14

r represents the radius of the circle

The diameter of the purple circle is 9 ft. Since both circles have a common center, the diameter of the yellow circle would be

9 + 2.5 + 2.5 = 9 + 5 = 14 ft

Radius = diameter/2

Radius of yellow circle = 14/2 = 7 ft

Circumference of yellow circle is

2 × 3.14 × 7 = 43.96 ft

What is the vertex of the function f(x) = x2 + 12x?

Stels [109]

Consider the function $f(x) = x^2 + 12x.$

You can rewrite it as

$f(x) = x^2 + 12x=x^2+2\cdot x\cdot 6=x^2+2\cdot x\cdot 6+6^2-6^2=(x+6)^2-36.$

When x=-6,

$f(-6)=(-6+6)^2-36=36.$

The vertex is (-6.-36).

Answer: correct choice is A.

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Check all that apply.

Kryger [21]

3x − 4y = 7
4y = 3x - 7
y = 3/4 x - 7/4 slope = 3/4

parallel lines, slope is the same so slope = 3/4
passes through the point (−4, −2)
equation
y + 2 = 3/4 (x + 4)
4y + 8 = 3x + 12
3x - 4y = -4

answer
3x − 4y = −4
