Point V shows -1,-1
The bottom left corner of a graph is always negative. So if there’s a point, both points will be negative

Find the slope of the line y= 1/8x-1. PLEASE SHOW WORK, I WILL MARK YOU BRAINLYIST IF YOU SHOW YOUR WORK!!!!!!!!

strojnjashka [21]

Answer:

1/8

Step-by-step explanation:

Slope intercept form is written as (y=mx+b)

<u>To define the variables: </u>

The m is the slope

The b is the y-intercept

This line is already written in slope intercept form, and in the place of m, or the slope, is the fraction 1/8... Therefore, the slope of the line is 1/8

The equation r(t)= (3t+9)i+(sqrt(2)t)j+(t^2)k is the position of a particle in space at time t. Find the angle between the veloc

andreev551 [17]

Answer:

$\theta= \frac{\pi}{2} +\pi \cdot i$ , for all $i = \mathbb{Z} \cup\{0\}$

Step-by-step explanation:

The velocity vector is found by deriving the position vector depending on the time:

$\dot r(t)= v (t) = 3 \cdot i +\sqrt{2} \cdot j + 2\cdot t \cdot k$

In turn, acceleration vector is found by deriving the velocity vector depending on time:

$\ddot r(t) = \dot v(t) = a(t) = 2 \cdot k$

Velocity and acceleration vectors at $t = 0$ are:

$v(0) = 3\cdot i + \sqrt{2} \cdot j\\a(0) = 2 \cdot k\\$

Norms of both vectors are, respectively:

$||v(0)||\approx 3.317\\||a(0)|| \approx 2$

The angle between both vectors is determined by using the following characteristic of a Dot Product:

$\theta = \cos^{-1}(\frac{v(0) \bullet a(0)}{||v(0)||\cdot ||a(0)||})$

Given that cosine has a periodicity of $\pi$ . There is a family of solutions with the form:

$\theta= \frac{\pi}{2} +\pi \cdot i$ , for all $i = \mathbb{Z} \cup\{0\}$

the line Plus shows the differences some students jumped during a field day competition what fraction of the students jumped 5 1

MissTica

Answer:

⅛

Step-by-step explanation:

Each mark (x) on the plot presents the distance that each student jumped.

There are 24 marks there, so it means there is a total of 24 students whose distance jumped were recorded.

Number of students that jumped 5½ ft = 3

Fraction of the students that jumped 5½ ft = no of students that jumped 5½ ft / total number of students

= 3/24

Simplify/reduce the fraction

= 1/8
