A quadratic equation is an equation whose leading coefficient is of the second degree. The given quadratic equation can be matched with its solution as shown below.

<h3>What is a quadratic equation?</h3>

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

The given quadratic equation can be matched with its solution as shown below,

2x² − 32 = 0 → x = √(32/2) → x = {-4, 4}

4x² − 100 = 0 → x = √(100/4) → x = {-5,5}

x² − 55 = 9 → x = √(9+55) → x = {-8,8}

x² − 140 = -19 → x = √(-19+140) → x = {-11,11}

2x² − 18 = 0 → x = √(18/2) → x = {-3, 3}

Number 4 I have no idea how to do.

Volume is a three-dimensional scalar quantity. The cost of the glass is $1312.24.

<h3>What is volume?</h3>

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the colony must be able to take a volume of 200,000 cubic meters, therefore, the diameter of the hemisphere will be,

The volume of Hemisphere = (2/3)πr³

200,000 = (2/3) × π × R³

R = 45.7

The area of the base of the hemisphere is,

Area of the base = πR² = π×(45.7)  = 6561.185 meters²

Given the cost of glass is $0.20 per square meter, therefore, the cost of the glass of the base will be,

Cost of glass = 6561.185 × 0.20 = $1312.24

Hence, the cost of the glass is $1312.24.

WARRIOR [948]
$72 - $30 = $42

It increased $42.



Now take this number and divide by the original number (first):

42 ÷ 30

This is 1.4, let's convert this to a percentage.
We now times it by 100



1.4 × 100

The answer is 140%
