If 43 liters of water are enough to water 25 of the plants in the house, how much water is necessary to water all the plants in the house? Write a multiplication equation and a division equation for the situation, then answer the question. Show your reasoning.
Which of the following functions is quadratic?
O A. F(x) = 5^2
O B. f(x) = 2/x
O c. f(x)=3(x-4)(x+3)
O D. f(x) = 2x^3 + 3x^2 - 5
if u look at it and and which ones have more then u will get ur answer
Option C is correct, f(x)=3(x-4)(x+3) is a quadratic function.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
In the given functions which are in the form of ax²+bx+c=0 such functions are considered as quadratic function.
The highest power of the variable x should be two.
f(x)=5² is not a quadratic function.
f(x) = 2/x is not a quadratic function.
f(x)=3(x-4)(x+3)
Let us simplify the function
f(x)=3(x²+3x-4x-12)
=3(x²-x-12)
f(x)=3x²-3x-36
So f(x)=3(x²+3x-4x-12) is a quadratic function.
Hence, Option C is correct, f(x)=3(x-4)(x+3) is a quadratic function.

Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo. Esto cambia la dirección de la señal.
3x+4≤7
Resta 4 en los dos lados.
3x≤7−4
Resta 4 de 7 para obtener 3.

The area of a square is 36 cm² what is the length of each side of the square
Answer:
6 cm
Step-by-step explanation:
take the sqaure root of 36 and get 6
Answer:
6 cm
Step-by-step explanation:
Formula for Area of A Square Is: [tex]A = s^2[/tex]
s - given side
We would need to take the square root of 36 to get the side length.
[tex]36 = s^2\\\\\sqrt{36} = \sqrt{s^2}\\\\\boxed{6 = s}[/tex]
Each side length should be 6 cm.

You can treat x and 2x+1 just as though they are real numbers.
So f(2x+1) = 3(2x+1) - 5 = 6x + 3 - 5 = 6x - 2

If the height of a cone is 7.5 cm and the radius is 2 cm, find the approximate volume of the cone.
Answer:
The volume of the cone is approximately 31.43 cm³Step-by-step explanation:
We know that:
Volume of cone: πr²h/3h = 7.5r = 2Work:
πr²h/3=> π x r² x h/3=> 22/7 x 2² x 7.5/3=> 22/7 x 4 x 2.5=> 22/7 x 10=> 220/7=> 31.43 (Rounded to nearest hundredth.)Hence, the volume of the cone is approximately 31.43 cm³
