The value of given Polynomial 25y³ - 36y = 0 is 0, 6/5, -6/5.

<h3>What is Polynomial?</h3>

A polynomial is a type of expression. An expression is a mathematical statement without an equal-to sign (=).

Here, given polynomial

              25y³ - 36y = 0

              y(25y² - 36) = 0

             y { (5y)² - (6)²} = 0

             y {(5y-6)(5y+6)} = 0

so, y = 0, or 5y-6 = 0  or 5y+6 = 0

      y = 0,  or  y = 6/5  or   y = -6/5

Thus, the value of given Polynomial 25y³ - 36y = 0 is 0, 6/5, -6/5.

The solution to 25y³ - 36y = 0 are y = 0, y = 6/5 and y =-6/5

<h3>How to solve the polynomial?</h3>

The polynomial is given as:

25y³ - 36y = 0

Factor out y in the above equation

y(25y² - 36) = 0

Split

y = 0 or 25y² - 36 = 0

Solving 25y² - 36 = 0, we have:

25y² - 36 = 0

Express 36 as 6² and 25 as 5²

(5y)² - 6² = 0

Apply the difference of two squares

(5y - 6)(5y + 6) = 0

Split

5y - 6 = 0 or 5y + 6 = 0

Solve for y

y = 6/5 or y = -6/5

Recall that:

y = 0

Hence, the solution to 25y³ - 36y = 0 are y = 0, y = 6/5 and y =-6/5

If y varies directly as x and x = 9 when y = 15 , find y when x = 33
poizon [28]
This would practically be very reliable of course. We can see in the sentence above that y and x, and x and y are both depending on each other. So, now that this has been considered, we can see that whenever "x" would be a certain number, this would show you that "y" would also be a certain number, and depending how much "x" or "y" would move, it would also change these variable no matter how they move.

This would be a matter of division. As we can see above on how 9 and 15 could be divisible down the line as they multiply.

Therefore, we would then see how many times would "x" which is 9, how many times that would go in 33.

Let's start!

\boxed{33\div9= \ (3.6)}

We take this "3.6" away from this, and we would plug it into "y".

We then do the following:

\boxed{3.6*15=55}

Therefore, when "x" = 33, "y" would then equal 55.

Your answer: \boxed{\boxed{\bf{y=55}}}

The table shows the distance the students a group of students walked during after-school practice. What was the total distance,
ser-zykov [4K]

First let's convert the decimal numbers to mixed numbers:

\begin{gathered} 3.4=3+0.4=3+\frac{4}{10}=3+\frac{2}{5}=3\frac{2}{5} \\ 1.75=1+0.75=1+\frac{75}{100}=1+\frac{3}{4}=1\frac{3}{4} \\ 2.25=2+0.25=2+\frac{25}{100}=2+\frac{1}{4}=2\frac{1}{4} \end{gathered}

Now, adding all the numbers, we have:

\begin{gathered} (3+\frac{2}{5})+(3+\frac{1}{5})+(1+\frac{3}{4})+(2+\frac{1}{4})+(1+\frac{7}{10}) \\ =(3+3+1+2+1)+(\frac{2}{5}+\frac{1}{5}+\frac{3}{4}+\frac{1}{4}+\frac{7}{10}) \\ =10+(\frac{3}{5}+1+\frac{7}{10}) \\ =11+(\frac{6}{10}+\frac{7}{10}) \\ =11+\frac{13}{10} \\ =12+\frac{3}{10}=12\frac{3}{10} \end{gathered}

So the correct option is B.

3. The height in feet of a thrown football is modeled by the equation
KonstantinChe [14]

The expression 30t mean that the velocity of the football is 30, while the term 16t² makes the function to be quadratic.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

f(t) = 6 + 30t – 16t²

Where f(t) is the height of the football after t seconds.

The constant 6 means the football was thrown from a height of 6 feet above the ground.

The expression 30t mean that the velocity of the football is 30, while the term 16t² makes the function to be quadratic.
