Answer:

2 real solutions.

Step-by-step explanation:

the discriminant is (b^2 - 4ac). This is 3^2 - 4(4)(-2), which gives us 41, a positive number. A positive number means that the equation will have 2 solutions.

n music, a quaver is one-eighth of a semibreve (whole note). What fraction of a semibreve is a hemidemisemiquaver? (Hint: hemi-,

Dmitry [639]

Answer:

$\dfrac{1}{64}$

Step-by-step explanation:

Hemi-, demi- and semi- are prefixes which mean <u>half</u>.

When applied to musical notation, each time a prefix is added it means the note's value is <u>halved</u>.

Therefore, if a quaver is one-eighth of a semibreve, then a <u>semiquaver</u> is half of a quaver, which means it's <u>one-sixteenth of a semibreve</u>.

$\large \begin{aligned}\sf quaver & = \sf\dfrac{1}{8}\:of\:a\:semibreve\\\\\implies \sf hemisemidemiquaver & = \sf \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2} \times quaver\\\\& = \sf \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{8}\\\\& = \sf \dfrac{1}{64}\:of\:a\:semibreve\end{aligned}$
