What is the area of a square with side lengths of 3/5 units?
umka2103 [35]

Answer:

We must solve 3/5 x 3/5.

3/5 x 3/5 = 0.36

The units we'll use is  because units are the unt we're given, and it is squared because it is the area of a shape.

Your final answer is 0.36

The graph shows the total fare, y, for a taxi ride with respect to the miles traveled, x.
Setler79 [48]

Answer:

y-intercept = 3

The y-intercept represents the initial fee before any miles are traveled.

Step-by-step explanation:

By definition, the <u>y-intercept</u> is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The coordinates of the y-intercept is (0, <em>b </em>).

Looking at your graph, it shows that the line crosses the y-axis at (0, 3). Therefore, the y-intercept = 3.

The y-intercept represents the initial fee before any miles are traveled. This means that the taxi ride already has a set amount of $3, regardless of the number of miles traveled. This is added to the total cost of the taxi fare, which is represented by y.

Find all values of k so that the trinomial x^2 + kx - 35 can be factored using integers
Korvikt [17]
(x-r_1)(x-r_2)=x^2-(r_1+r_2)x+r_1r_2

So the trinomial x^2+kx-35 can be factored as long as

\begin{cases}r_1+r_2=-k\\r_1r_2=-35\end{cases}

has integer solutions for r_1,r_2. Clearly, both have to be factors of -35, which leaves only a handful of cases:

(r_1,r_2)=(1,-35)\implies r_1+r_2=-34
(r_1,r_2)=(-1,35)\implies r_1+r_2=34
(r_1,r_2)=(5,-7)\implies r_1+r_2=-2
(r_1,r_2)=(-5,7)\implies r_1+r_2=2

So the possible values of k are \pm34 and \pm2.
