Answer:

7π cm² ≈ 22.0 cm²

Step-by-step explanation:

The shaded area is the difference between the area of Circle B and the areas of Circle C and Circle O. That is, those white areas are subtracted from the area of Circle B to get the shaded area.

The formula for the area of a circle is

A = πr²

Using this, we find ...

Circle B area = π(3 cm)² = 9π cm²

Circle C area = Circle O area = π(1 cm)² = π cm²

Then the shaded area is ...

Shaded Area = Circle B area - Circle C area - Circle O area

= (9π cm²) - (π cm²) - (π cm²)

= 7π cm² ≈ 22 cm²

lilavasa [31]

We will use the Sine Law:
$\frac{sin 54.33}{b}= \frac{sin29.16}{3} \\ b = \frac{3sin54.33}{sin29.16}$
b = 5.001

Given the linear system:

azamat

Answer:

y=x+1/2z+-1/2

Step-by-step explanation:

Let's solve for y.

2x−2y+z=1

Step 1: Add -2x to both sides.

2x−2y+z+−2x=1+−2x

−2y+z=−2x+1

Step 2: Add -z to both sides.

−2y+z+−z=−2x+1+−z

−2y=−2x−z+1

Step 3: Divide both sides by -2.

-2y/-2 = -2-z+1/-2

y=x +1/2z+-1/2

Leonard is studying the relationship between the fuel efficiency in miles per gallon (mpg), y, and the speed in miles per hour (

Nataliya [291]

Answer:

D. There is a nonlinear relationship between the speed and fuel efficiency.

Step-by-step explanation:

A desirable residual plot should show a horizontal band with points randomly distributed about the horizontal axis.

Leonard's plot is definitely nonlinear.

The residuals show a good fit to a parabola.

This suggests that the relation between speed and fuel efficiency may be parabolic.
