Need a little help on this one

Mathematics
1 answer:
Vesna [10]1 year ago
8 0

Answer:

  • numerator: 4
  • denominator: 5y

Step-by-step explanation:

You want the simplified form of (8x²y²)/(10x²y³).

<h3>Cancel common factors</h3>

A rational expression is simplified by cancelling common factors from numerator and denominator. When exponents are involved, the rules of exponents apply. (It can be helpful to think of an exponent as telling you how many times the factor is replicated.)

  \dfrac{8x^2y^2}{10x^2y^3}=\dfrac{8}{10}\cdot\dfrac{x^2}{x^2}\cdot\dfrac{y^2}{y^3}=\dfrac{4}{5}\cdot 1\cdot\dfrac{1}{y}=\boxed{\dfrac{4}{5y}}

The numerator is 4.

The denominator is 5y.

Prove this trigonometric equation;<br><br> - tan^2x + sec^2x = 1,
alekssr [168]
Hey there :)

- tan²x + sec²x = 1    or    1 + tan²x = sec²x

sin²x + cos²x = 1 
Divide the whole by cos²x

\frac{sin^2x}{cos^2x} + \frac{cos^2x}{cos^2x} = \frac{1}{cos^2x}

\frac{sinx}{cosx} = tanx so \frac{sin^2x}{cos^2x} = tan^2x
and
\frac{1}{cosx} = secx so \frac{1}{cos^2x} = sec^2x

Therefore,
tan²x + 1 = sec²x
Take tan²x to the other side {You will have the same answer}

1 = - tan²x = sec²x or sec²x - tanx = 1
