Answer:

-4, 9, -1

Step-by-step explanation:

x³ - 4x² - 41x - 36

= x²(x + 4) - 8x² - 41x - 36

= x²(x + 4) - 8x(x + 4) - 9x - 36

= x²(x + 4) - 8x(x + 4) - 9(x + 4)

= (x + 4)(x² - 8x - 9)

= (x + 4) (x - 9)(x + 1)

so the zeros of f(x) are: -4, 9, -1

The LA dodgers hit the most home runs in 2014. The number of Home runs accounted for 6% of the entire major league baseball home

Hitman42 [59]

Answer:

To answer the question, we will need to find the 6% (the home runs of the LA Dodgers) of 583 (the entire Major League Baseball home run count).

To do that, first we are going to divide 6% by 100% to convert it to a fraction and get rid of the percentage signs :

Now we can multiply our fraction by the entire Major League Baseball home run count to get the home runs of the Dodgers:

We can conclude that the LA Dodgers hit approximately 35 home runs.

Which of these best explains the next step to simplify this expression? 3y−45=35y−4 Question 22 options: Make the –4 exponent in

NISA [10]

The value of y from the give expression is 1

<h3>Expressions and equations</h3>

Give the following expression

$\frac{3y^{-4}}{5} = \frac{3}{5y^{-4}}$

Cross multiply the given expression

$3y^{-4}\times 5y^{-4}= 5 \times 3\\15y^{-8}=15\\$

Divide both sides by 15

$y^{-8}=1\\\frac{1}{y^8} =1\\y^8=1\\y=1$

Hence the value of y from the given expression is 1
