Rounded to the nearest hundredth , what is the positive solution to the quadratic equation 0=2x^2+3x-8

The positive solution to the quadratic equation is x = 1.39

Given quadratic equation is

The general quadratic equation is of form:

Now comparing the general equation with the given equation we get

a = 2 , b = 3 and c = -8

The formula to determine roots of the quadratic equation is:

On plugging in vlaues, we get

On solving we get,

x = 1.39  OR  x = -2.89  

Hence , the positive solution to the quadratic equation  is x = 1.39

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
