<h2>Solution</h2>

Given :-

diameter of circle = 12

Then,

Radius will be circle= 12/2 = 6

<h3>Explanation</h3>

Using Formula

★Circumference of circle = 2πr

Keep Value

==> Circumference of circle = 2π × 6

==> Circumference of circle = 12π

<h2>Hence</h2>

your answer will be option number b.

Answer:

b. 12π

Step-by-step explanation:

C= 2πr

R= D/2= 12/2= 6

C= 2x3.14x6

2x6= 12

C= 12π

Jeanne babysits for $6 per hour. She also works as a reading tutor for $10 per hour. She is only allowed to work 20 hours per we

Allushta [10]

Part a) Use a system of inequalities to model the scenario

Let

x-------> represent babysitting hours

y-------> represent tutoring hours

we know that

--------> inequality

Part b) Use the model created in part A to create a graph representing Jeanne’s probable income earned and possible number of hours worked this week

we know that

--------> inequality

This inequality represent Jeanne’s possible number of hours worked this week

Using a graph tool

the solution of this inequality is the shaded area

see the attached figure N

--------> inequality

This inequality represent Jeanne’s probable income earned this week

Using a graph tool

the solution of this inequality is the shaded area

see the attached figure N

Part c) Analyze the set of coordinate values that represent solutions for the model created in part A. Choose one of the coordinates within the solution and algebraically prove that the coordinate represents a true solution for the model

we have the system of inequalities

--------> inequality

the solution of the system of inequalities is the shaded area

using a graph tool

see the attached figure N

Let

------> see the attached figure N

The point belongs to the shaded area, so it is a system solution.

If the point is a solution, it must satisfy both inequalities.

Prove algebraically

substitute the value of x and y in the inequalities

inequality

------> is ok

inequality

-------> is ok

the point A satisfy both inequalities

therefore

the point A is a solution of the system

When you see questions of this nature, test the individual inequalities and look out for their intersection.

For
$y < \frac{2}{3} x$
Choose a point in the lower or upper half plane created by the line
$y = \frac{2}{3} x$
The above line is the one which goes through the origin.

Now testing (1,0) yields,

$0 < \frac{2}{3} (1)$
That is,

$0 < \frac{2}{3}$
This statement is true. So we shade the lower half of
$y = \frac{2}{3} x$

For
$y \geqslant - x + 2$
We test for the origin because, it is not passing through the origin.

$0 \geqslant - (0) + 2$
This yields
$0 \geqslant 2$
This statement is false so we shade the upper half.

The intersection is the region shaded in B. The top right graph

Answer: a) add n+1 to the previous term

b) add the previous two terms

d) subtract n+1 from the previous term

e) multiply the previous term by 3

f) subtract 2 from previous term then add 5 to the next term

Step-by-step explanation:

a) 1, 3, 6, 10

∨ ∨ ∨

+2 +3 +4 The next term is 10 +5 = 15

b) 1, 2, 3, 5

∨ ∨ ∨

=3 =5 =8 The next term is 5 + 8 = 13

d) 8, 7, 5, 2

∨ ∨ ∨

-1 -2 -3 zThe next term is 2 - 4 = -2

e) 1, 3, 9, 27

∨ ∨ ∨

×3 ×3 ×3 The next term is 27 × 3 = 81

f) 49, 47, 52, 50, 55

∨ ∨ ∨ ∨

-2 +5 -2 +5 The next term is 55 - 2 = 53

The following term is 53 + 5 = 58
