What is the zeros of the quadratic function y=x^2+14x+24

Mathematics
1 answer:
777dan777 [17]3 years ago
6 0

Step-by-step explanation:

{x}^{2}  + 14x + 24 = 0 \\  {x}^{2}  + 12x + 2x + 24 = 0 \\ x(x + 12) + 2(x + 12) = 0 \\ (x + 12)(x + 2)  = 0\\ x =  - 12 \\ x =  - 2

Please simplify the following trigonometric identity.
lesya692 [45]

<u>Examining the question:</u>

We are given the expression:

\frac{1}{Sec(\alpha)-Tan(\alpha)}

We know from Basic trigonometry that:

Sec(\alpha) = \frac{1}{Cos(\alpha)}

Tan(\alpha) = \frac{Sin(\alpha)}{Cos(\alpha)}

<u>Simplifying the expression:</u>

Replacing these values in the given expression, we get:

\frac{1}{\frac{1}{Cos(\alpha)} -\frac{Sin(\alpha)}{Cos(\alpha)} }

Since the denominator of both the values in the denominator is the same:

\frac{1}{\frac{1-Sin(\alpha)}{Cos(\alpha)} }

We know that \frac{1}{\frac{a}{b} } = \frac{b}{a}, using the same property:

\frac{Cos(\alpha)}{1-Sin(\alpha)}

and we are done!

Masteriza [31]
Let's add the percentage of the processing new books and repairing bindings.

6%+9%= 15%

We need to find how many times that goes into 44%

15%*3= 45

It is about 3 times more than she will spend processing new books and be repairing bindings.

I hope this helps!

The quotient of 5n^2(m^2+2m-3)/10n(m^2-3m+2) divided by n^2(m^2-3m-18)/4n^2(m^2-8m+12)
slavikrds [6]
\dfrac{ 5n^2(m^2+2m-3)}{10n(m^2-3m+2)} \div  \dfrac{n^2(m^2-3m-18)}{4n^2(m^2-8m+12)}

\dfrac{ 5n^2 (m + 3)(m - 1)}{10n( (m - 1)(m - 2)} \div  \dfrac{n^2(m + 3)(m - 6)}{4n^2(m - 2)(m - 6)}

\dfrac{ 5n^2 (m + 3)(m - 1)}{10n( (m - 1)(m - 2)} \times  \dfrac{4n^2(m - 2)(m - 6)}{n^2(m + 3)(m - 6)}

= 2n
