The <em>speed</em> intervals such that the mileage of the vehicle described is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h]

<h3>How to determine the range of speed associate to desired gas mileages</h3>

In this question we have a <em>quadratic</em> function of the <em>gas</em> mileage (g), in miles per gallon, in terms of the <em>vehicle</em> speed (v), in miles per hour. Based on the information given in the statement we must solve for v the following <em>quadratic</em> function:

g = 10 + 0.7 · v - 0.01 · v²      (1)

An effective approach consists in using a <em>graphing</em> tool, in which a <em>horizontal</em> line (g = 20) is applied on the <em>maximum desired</em> mileage such that we can determine the <em>speed</em> intervals. The <em>speed</em> intervals such that the mileage of the vehicle is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h].

Make y the subject of the formula <br><br> W= x squared - 2yz
AveGali [126]

Answer:

The formula    y = \frac{x^{2} }{2z} + \frac{W}{2z}

Step-by-step explanation:

<em><u>Explanation</u></em>

Given   W = x² - 2 y z

          2 y z = x² + W

Dividing '2z' on both sides , we get

         \frac{2yz}{2z} = \frac{x^{2} + W}{2z}

⇒       y = \frac{x^{2} }{2z} + \frac{W}{2z}
