The given polynomial is a 3rd degree polynomial so it has a total of three roots.

And we know, where the curve (of polynomial) cuts the x - axis is its real root. so, from the graph we can infer that the given polynomial has 2 real roots [ as it cuts the x - axis at two points, i.e x = -2 and x = 1 ]

Hence, Number of real roots = 2

Number of imaginary roots = total roots - real roots

i.e 3 - 2 = 1

So, number of imaginary roots = 1

The ordered pairs are on the inverse function are (-5, -2) and (4, 1)

Inverse functions are the opposite of an original equation. This means that for a function f(x), the inverse of the function f(x) is f-(x); it also represents the opposite function

From the question, we have the following coordinate points

Rewrite the points as:

Remove the inflection point.

So, we have

The next step is to switch/swap the positions of x and y in the above equation ordered pairs

The unknown angles of the triangle and trapezium are as follows:

A triangle is a polygon with three sides.

The sum of angles in a triangle is 180 degrees.

Therefore, angle 1 can be found as follows:

∠1 = 180 - 40 - 30

∠1 = 180 - 70

∠1 = 110 degrees.

Therefore, angle 2 can be found as follows:

∠2 = 180 - 40 - 40 - 30 - 30

∠2 = 180 - 80 - 60

∠2 = 180 - 140

∠2 = 40 degrees.

A quadrilateral is a polygon with 4 sides. The sum of angles in a quadrilateral is 360 degrees.

Therefore, the triangle in the trapezium is an isosceles triangle. The base angles are equal.

Hence,

∠1 = 180 - 30 - 30

∠1 = 180 - 60

∠1 = 120 degrees

Sum of angles in the same transversal is supplementary.

Therefore,

90 + 30 + ∠2 = 180

∠2 = 180 - 120

∠2 = 60 degrees

Cost of the health insurance is $11657.14

What is cost?

A cost is the worth of money that has been used up to create something or supply a service and is thus no longer accessible for use in production, research, retail, or accounting. In business, the cost might be one of acquisition, in which case the money spent to obtain it is recognized as cost. In this situation, money is the input that is used to purchase the item. This acquisition cost might be the total of the original producer's production expenses and the acquirer's additional transaction costs over and above the amount paid to the producer. Typically, the price includes a profit margin above the cost of manufacture.

14% of x = 68

x = 68 x 100/14

Algebraic expression for Height of Balloon 2 = 7x and Height of Balloon 3 = x/2.

Heights reached by balloons 1, 2, 3 and 4 will be 54.73, 383.11, 27.36, 84.73 respectively.

We have the following given information as per the question

Balloon 1 reaches x m.

Balloon 2 reaches a height of 7 times balloon 1

∴ Balloon 2 reaches 7x m.

Balloon 3 reaches a height of half that of balloon 1.

∴ Balloon 3 reaches [tex] \frac{x}{2} [/tex] m.

Balloon 4 reaches a height of 30 meters more than balloon 1.

∴ Balloon 4 reaches ( x + 30 ) m.

Now As given The total height reached by all the balloons was 550 meters.

∴ Height of Balloon 1 + Height of Balloon 2 + Height of Balloon 3 + Height of Balloon 4 = 550 meter

∴ x + 7x + [tex] \frac{x}{2} [/tex] + (x + 30 ) =550

∴ 9.5x + 30 = 550

∴ 9.5x = 550 - 30

∴ 9.5x = 520

∴ x = 520/9.5

∴ x = 54.73 meter

(a) Algebraic expression to model the heights reached by balloons 2, 3 will be

Height of Balloon 2 = 7x = 7(54.73) = 383.11 meter

Height of Balloon 3 = x/2 = 54.73 / 2 = 27.36 meter

(b) The heights reached by balloons 1, 2, 3 and 4 will be as follows

Height of Balloon 1 = x = 54.73 meter.

Height of Balloon 2 = 7x = 7(54.73) = 383.11 meter

Height of Balloon 3 = x/2 = 54.73 / 2 = 27.36 meter

Height of Balloon 4 = x + 30 = 54.73 + 30 = 84.73 meter

Cos(0) = - 0.949 this expression is accurate for the unit circle which is intersected at point by angle 8 according at point (-0.949, 0.314).

An elliptical plane figure is a circle. From a fixed location known as the circle's center, each point on the circle is equally distant. It has a two-dimensional (2D) shape and a radius value. The Latin word "circulus" (which means little ring) is the root of the English word "circle."A circle is a two-dimensional shape that is made up of a collection of points that are spaced out from the center of the circle (its fixed point) on the plane by a fixed or constant distance (radius). The radius of a circle is the fixed distance between points that is fixed from the fixed point, which is known as the origin or center of the circle.

The terminal side of angle 0 intersects the unit circle at point P(- 0.949, 0.314) That means, OQ = 0.949 and PQ = 0.314

Here, OP is the radius of the unit circle. So, OP = 1

In respect of angle 0, the adjacent side is OQ and the hypotenuse is OP.

We know that,

cos= [tex]\frac{adjacent}{hpotenusey}[/tex]

So,

cos(0) = - [tex]\frac{OQ}{OP}[/tex]  [As the angle is in quadrant II, so cos is negative]

cos(0) = - [tex]\frac{-0.949}{1}[/tex]

cos(0) = - 0.949

False, The product of two irritational numbers is either rational or irrational numbers.

A rational number is a number expressed in the form of p/q where p and q are integers and q should not be zero. Example: 2/5, 24

Whereas an irrational number is a number that is not rational in nature means it neither be expressed in the form of p/q nor in ratio terms. Example: √12, √3

Product of two irrational numbers: √2* √2 = 4 (which is a rational number)

Product of again two irrational numbers: √2*√3= √6 ( which is an irrational number)

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

The product of two irrational numbers √3 ×√3 = 3

This is a rational number.

Again, the product of two irrational numbers: √5 ×√3 = √15

The point is a solution if it satisfies the inequality.

In this case, the inequality is y ≤ (1/3)x + 4, so replacing (x, y) = (-6, 2), we get:

y ≤ (1/3)x + 4

2 (1/3)(-6) + 4≤

2 ≤ -2 + 4

2 ≤ 2

Since 2 is equal to 2, the inequality is satisfied and (-6, 2) is a solution.

Mike works 40 hours at job A and 18 hours at job B.

Simultaneous equations are two or more algebraic equations that share the same unknown variables and have the same solution for each of them. This suggests that the equations are simultaneous and have a single solution.

Given:

Mike makes $7 per hour at job A and $8 per hour at job B.

Let x be the number of hours Mike spends working at job A and y be the number of hours he spends working at job B.

Since he works a total of 58 hours per week,

x + y = 58

His total pay for one week is ​$424.

7x + 8y = 424

Solving both equations simultaneously we get,

From the first equation, we have, y = 58 - x

Putting the value of y in the second equation,

7x + 8(58 - x) = 424

7x + 464 - 8x = 424

8x - 7x = 464 - 424

x = 40

So, now calculate y = 58 - 40 = 18

Therefore, Mike spends 40 hours working at job A and 18 hours working at job B.
