Answers

(a) The sum of the interior angles of the nonagon is 1260°.

(b) The sum of the interior angles of the dodecagon is 1800°.

(c) The sum of the interior angles of the 23-gon is 3780°.

What is a convex polygon?

A convex polygon is a closed figure with all of its interior angles less than 180° and all of its vertices pointing outward. The term convex refers to a shape with a curve or a projecting surface. To put it another way, all of the lines across the outline are straight and point outwards.

The formula for the sum of the interior angle is (n -2)180°.

The number of sides of the nonagon is 9.

Putting n = 9 in (n -2)180°, to find the sum of interior angle of nonagon:

The sum of the interior angle is (9 -2)180° = 1260°.

The number of sides of dodecagon is 12.

Putting n = 12 in (n -2)180°, to find the sum of interior angle of dodecagon:

The sum of the interior angle is (12 -2)180° = 1800°

Putting n = 23 in (n -2)180°, to find the sum of interior angle of 23-gon:

The sum of the interior angle is (23 -2)180° = 3780°.

what is polynomial ?

In mathematics, the intersection point is the place on the y-axis where the slope of the line passes. a place where the y-axis crosses on a line or curve. Y = mx+c, where m stands for the slope and c for the y-intercept, is used as the equation for the straight line to show this. The slope (m) of the line and its y-intercept (b) are highlighted in the equation's intercept form. When an equation has the intercept form (y=mx+b), the slope is m and the y-intercept is b. Some equations can also be rewritten so that they appear to be slope intercepts. If y=x is rewritten as y=1x+0, for instance, the slope and y-intercept are both changed to 1.

It follows from the task content that the domain of the piecewise function which is as described in the task content be determined.

The domain of a function is the set of all possible input values of that function.

For the first piece, since the curve increases from left ( -∞ ) through a point and ends at a closed point (-2, -2). Hence, the set of inputs for the first piece in interval notation is; ( -∞, -2 ].

Also, for the second piece which is linear with an open point at (-2, -1) and ends at an endpoint (2, 1). Hence, the domain of the second piece is; [-2, 2].

Finally, the third piece is curved with an endpoint at (2, 1) and continues to increase tonthe right. Hence, the domain of the third piece is; [2, ∞)

How do the graphs of the functions f(x) = (3/2)x and g(x)

Answers

The function g(x) = (2/3)ˣ is the graph of the function f(x) = (3/2)ˣ reflected over y-axis.

What is function?

A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math.

f = {(a, b)| for all a ∈ A, b ∈ B}.

Given, the function

f(x) = (3/2)ˣ

g(x) = (2/3)ˣ

We have to compare the graphs of the functions f(x) and g(x).

Exponential function is of the form: y = abˣ

Where a is the initial value and b is the growth factor.

a) If b > 1, then the function is an exponential growth function.

b) If 0 < b < 1, then the function is an exponential decay function.

f(x) = y = (3/2)ˣ

The function is an exponential growth function.

The rule of reflection over y-axis:

(x, y) → (-x, y)

Applying the rule, we get,

(3/2)ˣ = (3/2)⁻ˣ

= (2/3)ˣ

= g(x)

Therefore, g(x) is graph of f(x) reflected over y-axis

Hence, graph of the function f(x) = (3/2)ˣ  reflected over y-axis is function g(x) = (2/3)ˣ .

Write a function in terms of $t$ that represents the situation.

Sales of $10,000 increase by 65% each year.

Answers

A function in terms of t that represents the situation of sales that is of $10,000 and increase by 65% each year is t = 10,000(1.65)ⁿ.

What is function?

An element of one non-empty set and an element of another non-empty set are said to have a special relationship when they are connected by a function in mathematics.

An assignment of an element from set Y to each element of set X, where set X is the domain and set Y is the codomain, is what is meant when a function is applied from a set X to a set Y.

We have given that f(t) is given by the Sales of $10,000 increase by 65% each year, i.e.

As sales of $10,000 increase by 65% each year.

The situation is represented by an exponential growth function.

The initial amount a = 10,000

The rate of growth r = 65% = 0.65

Therefore, the function will be:

                                                   t = a(1 + r)ⁿ                                                  

Where,

t represents the final amount.

a represents the initial amount

r represents the rate of growth

1+r represents the growth factor

n represents the time.

⇒  t = a(1 + r)ⁿ      

⇒  t = 10,000(1 + 0.65)ⁿ    

⇒  t = 10,000(1.65)ⁿ    

Thus, a function in terms of t that represents the situation of sales that is of $10,000 and increase by 65% each year is t = 10,000(1.65)ⁿ.

The costs of producing the gloves are $2 for a small pair and $4 for a large pair. Wanda has 16 hours available to sew gloves. The materials to make the gloves must cost at most $40. The system of linear inequalities represents this situation.

{45x+120y≤9602x+4y≤40

Answers

The point represents the number of small gloves is 16 and the number of large gloves is 2.

What is linear inequality?

According to the mathematical definition of inequality, neither side is equal. When a relationship leads to a non-equal comparison between two expressions or numbers, it is known as an inequality in mathematics. The equal sign "=" in this statement can be replaced with any of the inequality symbols, such as greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), or not equal to (≠).

Given  Wanda sews small and large gloves,

time for small gloves = 45 minutes

time for large gloves = 120 minutes

total time = 16 hours = 960 minutes

let x be the number of small gloves and y be the number of large gloves,

inequality equation is 45x + 90y ≤ 960

and the cost of small gloves = $2

cost of large  gloves = $4

total amount = $40

equation 2x + 4y ≤ 40

let us assume the system of inequality in form of a linear equation,

45x + 90y = 960

2x + 4y = 40

by solving the equations

the equation is written as

x = 20 - y

45(20 -y) + 90y = 960

y = 2

and x = 16

so the minimum values for x and y are 16 and 2 to maximize the profit Wanda should not decrease the production of small gloves from 16 and large gloves to 2.

Hence the point of maximization is (16, 2).
