jesse drives to work. The distance jesse's car travles (d) on a number of gallons of gas (g) is given y the equation d=15g.

Mademuasel [1]

You need to know what the distance jesse traveled is and then the number of gallons of gas she has then you plug it it.

distance equals 15 times the amount of gas in gallons
d=15g

What are the roots for the equation x^2-2x+37=0 in simplest a+bi form

Gnesinka [82]

$\boxed{x_{1}=1+6i} \\ \\ \boxed{x_{2}=1-6i}$

<h2>Explanation:</h2>

Since we need to write the roots in the simplest form:

$a+bi$

It is obvious that the roots are complex. To solve this, let's use the quadratic formula. For the Standard Equation:

$ax^2+bx+c=0$

The Quadratic Formula is:

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} \\ \\ Here: \\ \\ x^2-2x+37=0 \\ \\ So: \\ a=1 \\ b=-2 \\ c=37 \\ \\ x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(37)}}{2(1)} \\ \\ x=\frac{2\pm \sqrt{4-148}}{2} \\ \\ x=\frac{2\pm \sqrt{-144}}{2} x=\frac{2\pm \sqrt{-1}\sqrt{144}}{2} \\ \\ x=\frac{2\pm 12\sqrt{-1}}{2} \\ \\ but \ \sqrt{-1}=i \\ \\ Two \ solutions: \\ \\ x_{1}=\frac{2+12i}{2} \\ \\ \boxed{x_{1}=1+6i} \\ \\ x_{2}=\frac{2-12i}{2} \\ \\ \boxed{x_{2}=1-6i}$

Sketch the graph of each function

jenyasd209 [6]

Answer:

See diagram

Step-by-step explanation:

First, consider the graph of the parent function $y=\cos x.$ This function has the period $2\pi.$

Rewrite the function $y=2(1+\cos (x-\frac{\pi}{2}))$ as $y=2+2\cos (x-\frac{\pi}{2}).$ The graph of this function has the same period of $2\pi,$ is twice streched and translated $\frac{\pi}{2}$ units to the right and 2 units up graph of the parent function (see diagram).
