Yakvenalex [24]

For the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -<u>4</u>x + <u>0.</u>

<h3>What is the equation?</h3>

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, at 2 hours before sunset, the temperature is 0°F. 2 hours after sunset, the temperature is −4°F and the equation representing the temperature y, in degrees Fahrenheit, at x hours after sunset.

The equation is obtained as,

y = -4x + 0.

Thus, for the given condition the equation represents the temperature y, in degrees Fahrenheit, at x hours after sunset will be y = -<u>4</u>x + <u>0.</u>

Find the height of the figure below if the triangle is an equilateral triangle and the surface area is 51.678 mm^2

Neko [114]

SA=bh

The base is an equilateral triangle that means that the base=2.7^3=19.683

51.678=19.683h

divide both sides by the base

$\frac{51.678=19.683h}{19.683}$

2.626mm=h
