Answer:

34.86 unit²

Step-by-step explanation:

[tex]A_{triangle}[/tex] = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex] , where s = [tex]\frac{P}{2}[/tex] ; P = a + b + c

[tex]A_{hexagon}[/tex] = 6 × [tex]A_{triangle}[/tex]

[tex]A_{circle}[/tex] = [tex]\pi r^2[/tex]

[tex]\pi[/tex] ≈ [tex]\frac{22}{7}[/tex]

The product of the polynomials is [tex]15x^4 - 8x^3 - 6x^2 - 22x - 15.[/tex]

Polynomial is an equation written with terms of the form kx^n.

where k and n are positive integers.

There are quadratic polynomials and cubic polynomials.

Example:

2x³ + 4x² + 4x + 9 is a cubic polynomial.

4x² + 7x + 8 is a quadratic polynomial.

We have,

To find the product of the polynomials (3x² - 2x - 3) (5x² + 4x + 5), we can use the distributive property of multiplication to multiply each term in the first polynomial by each term in the second polynomial, and then combine like terms.

We can start by multiplying the first term in the first polynomial, 3x^2, by each term in the second polynomial:

3x² (5x² + 4x + 5)

= [tex]15x^4 + 12x^3 + 15x^2[/tex]

Next, we multiply the second term in the first polynomial, -2x, by each term in the second polynomial:

-2x(5x² + 4x + 5) = -10x³ - 8x² - 10x

Finally, we multiply the third term in the first polynomial, -3, by each term in the second polynomial:

-3(5x² + 4x + 5) = -15x² - 12x - 15

Putting these three results together, we have:

(3x² - 2x - 3) (5x² + 4x + 5)

= [tex]15x^4 + 2x^3 - 3x^2 + 12x^2 - 10x^3 - 10x - 15x^2 - 12x - 15[/tex]

Simplifying and collecting like terms, we get:

(3x² - 2x - 3)(5x² + 4x + 5)

[tex]15x^4 - 8x^3 - 6x^2 - 22x - 15[/tex]

Therefore,

The product of the polynomials is [tex]15x^4 - 8x^3 - 6x^2 - 22x - 15.[/tex]

Answer:

35

Step-by-step explanation:

1 foot = 12 inches

so (multiply both by 9)

9 feet = 108 inches

108 divided by 15 = 7.2

the .2 part can't be used, so each roll can make 7 pieces of ribbon

Theres 5 rolls of ribbon so multiply 7 by 5 which is 35

The prism shown consists of 6 parallelograms and the surface area of the prism shown in the figure is 48 square inches.

The surface area is equal to the sum of all the areas of the sides of the figure.

The figure shown consists of 6 parallelograms. The area for calculating the area of a parallelogram is expressed as:
Area = Base * Height

Surface area = 4(2*4) + (4 * 4)
Surface area = 4(8) + 16
Surface ares = 48 square in

Hence the surface area of the prism is 48 square inches.

Answer:

13 Quarters, 22 Dimes

Step-by-step explanation:

.10d + .25q = 5.45

.10 (35 - q) + .25q = 5.45

3.5 - 10q + .25q = 5.45

.25q - .10q = 5.45 - 3.5

.15q = 1.95

q = 13

Plug the value of q to solve for d, or the number of dimes.

d = 35 - q

d = 35 - 13

d = 22

Answer: for sure the answer is increased rapidly

Step-by-step explanation:

The population of the city increased rapidly for the first four months and then slowly approached 7000 people.

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

WE have given the  graph shows the population of a city n months after the establishment of a new automobile plant in the city.

We can see that at 4000 people, the graph increases and then become constant at the rate of 7000 people.

So we can conclude that the population of the city increases rapidly for the first four months and then slowly approached 7000 people.

The equation of the line of best fit is an illustration of a linear function

The teenager would spend $9 on food if he or she is at the mall for three hours.

The equation of the line of best fit is given as:

y = 2x + 3

When the teenager spends 3 hours in the mall, it means that:

x = 3

So, we have:

y = 2 * 3 + 3

Evaluate the product

y = 6 + 3

Evaluate the sum

y = 9

Hence, the teenager would spend $9 on food if he or she is at the mall for three hours.
