The volume of the cone and pyramid are the same.
Formula for volume of cone = ⅓(144π × h)
What is the Volume of a Triangular Pyramid and a Cone?Volume of cone = ⅓[πr² × height of cone)
Volume of triangular pyramid = ⅓[(½bh × height of pyramid)]
Also note the following:
Area of a circle = πr²
Area of a triangle = ½bh
Part A:
Area of circle 1 = πr² = π(12²) = 144π units²
Area of circle 2 = πr² = π(6²) = 36π units²
Area of circle 3 = πr² = π(3²) = 9π units²
Area of triangle 1 = ½(24)(12π) = 144π units²
Area of triangle 2 = ½(12)(6π) = 36π units²
Area of triangle 3 = ½(6)(3π) = 9π units²
Part B: Based on our results in part A, the volumes of the cone and pyramid, having the same height are the same.
Part C:
Volume of pyramid = ⅓(144π × h)
Using this measurement and our conclusion in part B:
Formula for the Volume of a cone = ⅓(144π × h)

The graph shown is the second derivative
⇒ first derivative equals the area between
- the second derivative function from 0 to 2
- the axis
Thus the first derivative f(2) equals [tex]8 + c[/tex]
c: represents the initial positionHowever there is an inital position for the first derivative ⇒ f(0) = 2.5
Therefore we must add the initial position to the first derivative found
f(2) = 8 + 2.5 = 10.5

What is a polynomial?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]

Dumpster #1 contains 45 fewer molded vegetables than dumpster #2. Dumpster #2 contains 80 fewer molded vegetables than dumpster #3. If there are 236 molded vegetables in all the dumpsters combined, how many vegetables are in dumpster #1?
Answer:
22 vegetables
Step-by-step explanation:
Set the #number of molded vegatables in dumpster 1 as X
The number of molded vegetables in 2 is x + 45 and the number of molded vegies in 3 is x + 45 + 80
x + x + 45 + x + 45 + 80 = 236 (combine similar terms)
Thats 3x = 66

What is the inverse of a function?Suppose that the given function is

such that:
[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]
(and vice versa).
It simply means, the inverse of 'f' is a reverse operator, that takes back the effect of 'f'
The equation is given below.

The vertices of a right triangle are p(-3,4), q(-3,-4) and r (7,-4). Explain algebratically whether or not (2,0) is on the side of the triangle.
Algebraically, it was possible to show that the point (2,0) is on the side (PR) of the given triangle.
RIGHT TRIANGLEA triangle is classified as a right triangle when it presents one of your angles equal to 90º. In this triangle from the trigonometric ratios or the Pythagoras Theorem ([tex](hypotenuse)^2=(side_1)^2+(side_2)^2[/tex]), it is possible finding angles or sides.
The question gives the points for a right triangle, you can draw the triangle, see the attached image. From the figure, it is possible to see the lengths for the sides PQ=8 and QR=10.
Linear EquationA linear function can be represented by a line. The standard form for this equation is: ax+b , for example, y=2x+7. Where:
a= the slope. If
a> 0 , the function is increasing; a< 0 , the function is decreasing;b=the constant term that represents the y-intercept.
The slope for the line PR can be calculated from the ratio between the side PQ and QR.
[tex]a=\frac{PQ}{QR}=\frac{4-(-4)}{(-3-7)}=\frac{8}{-10} =-0.8[/tex]
From the attached figure, it is possible to see that the y-intercept is (2,0). Therefore, the given point is on the side PR, but the question asks to show this algebraically.
From the Standard form (ax+b), the equation for the line PR will be: y=- 0.8x+b. After that, you should replace the coordinates of the given point P (-3,4) in the equation line: y=-0.8x+b for finding b.
4=-0.8*(-3)+b
4=2.4+b
b=4-2.4= 1.6
Then, the equation line y=-0.8x+1.6.
Now you should replace the x-coordinate for the point (2,0) in the equation y=-0.8x+1.6.
y=-0.8*2+1.6
y=-1.6+1.6
y=0
The calculated y-coordinate is the same the y-coordinate for the point (2,0), thus the point (2,0) is on the side of the triangle.

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.
What is Graph?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.
