Answer:Parabolas always have a lowest point. This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

<h3>Further explanation</h3>

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)

Formula used:

$\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}$

Fractions either proper or mixed (consisting of numerators and denominators) or decimal forms

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert proper fractions to percent forms is by multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number

35% from Several trays of danishes are filled with cream

There are four (4) trays

18 danishes on each tray
