Determine the height
tangare [24]

Answer:

The height of the model is 138 cm.

Step-by-step explanation:

Simply multiply the height by the scale factor.

230*0.006

= 1.38 m

We need to convert this measure to centimeters. Centimeters are 1/100 of a meter. Therefore, we can multiply 1.38 meters by 100 to find how many centimeters it is equal to.

1.38*100 = 138

The height of the model is 138 cm.

<h3>What is Discriminant Formula?</h3>

The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equationax^{2} +bx+c=0 is D =b^{2} -4ac

If D > 0, then the equation has two real distinct roots.

If D = 0, then the equation has only one real root.

Given that: Area\; of \;walkway,\; a(w)\;= 4w^{2} + 100 w

also, area of walkaway = 464 square feet.

So, 4w^{2} + 100 w =464

     4w^{2} + 100 w -464=0

Using Discriminant method,

a=4, b=100, c=-464

w= \frac{-b\pm\sqrt{b^{2}-4ac} }{2a}

w= \frac{-100\pm\sqrt{(100)^{2}-4*4*(-464)} }{2*4}

w= \frac{-100\pm\sqrt{17424} }{8}

So, w_1= \frac{-100+\sqrt{17424} }{8} \;\;\;\; w_2= \frac{-100-\sqrt{17424} }{8}

w_1= \frac{-100+132 }{8} \;\;\;\; w_2= \frac{-100-132}{8}

w_1 = 4 \;\;\;\; and \;\;\; w_2= -29

Hence the width of the walkaway be 4 feet.
