Answer: Choice A. It travels for 1 hour, stops for 1 hour, then travels for 3 hours

------------------------------------------------

Any portion of the graph that isn't flat and horizontal is when the car is traveling. In this case, it's the portion from x = 0 to x = 1 (the first hour of travel) and the portion from x = 2 to x = 5 (the final three hours of travel). The flat portion starts at x = 1 and stops at x = 2. So this represents 1 hour of rest. This is where the distance (y) isn't changing.

Diagram 1 shows absolute function of f(x)= 3x-1a)State the domain for that functionb)State the value of a

omeli [17]

The function given is,

$f(x)=3x-1$

a) Domain

This is the set of all points over which a function is defined.

Therefore, the domain of the function is

$-2\leq x\leq1$

b) Solving for the value of a

To solve for the value of a, the value of y = 0 at x = a

Therefore,

$\begin{gathered} f(x)=3x-1 \\ \text{where,} \\ f(x)=y=0 \\ x=a \end{gathered}$

Solving for a

$\begin{gathered} 0=3(a)-1 \\ 0=3a-1 \\ \end{gathered}$

Collect like terms

$\begin{gathered} 3a=0+1 \\ 3a=1 \end{gathered}$

Divide both sides by 3

$\begin{gathered} \frac{3a}{3}=\frac{1}{3} \\ a=\frac{1}{3} \end{gathered}$

Hence,

$a=\frac{1}{3}$

Solve the following quadratic equation using the quadratic formula. Which of the following expressions gives the numerators of t

Illusion [34]

I hope the choices for the numerators of the solutions are given.

I am showing the complete work to find the solutions of this equation , it will help you to find an answer of your question based on this solution.

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

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

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = 10, b = -19 and c = 6.

Next step is to plug in these values in the above formula. Therefore,

$x=\frac{(-19)-\pm\sqrt{(-19)^2-4*10*6}}{2*10}$

$=\frac{19\pm\sqrt{361-240}}{20}$

$=\frac{19\pm\sqrt{121}}{20}$

$=\frac{19\pm11}{20}$

So, $x=\frac{19-11}{20} ,\frac{19+11}{20}$

$x=\frac{8}{20} , \frac{30}{20}$

So, $x= \frac{2}{5} ,\frac{3}{2}$

Hope this helps you!
