Which best describe a vector

1 answer:

ANEK [815]3 years ago

6 0

Answer:

Vectors are used to represent physical magnitudes that have an associated address.For example,if we want to represent the displacement of an object,it is not enough to describe only the distance as 10 meters, it is also necessary to describe in which direction the displacement occurred,for example,30°towards the northeast.

Hope this helps:)

for each x-y table given,copy the table, find the pattern and fill in the missing entries. Then write the rule for the pattern i

mash [69]

Answer:

see the attached for the table and rules

Step-by-step explanation:

a) A graph of the given points shows they lie on the same line, one with a slope of 3 and a y-intercept of 2. Thus the rule is ...

y = 3x +2

see the attachment for table values

__

b) The ratios of given points are all the same: y/x = 5/2, so that is the constant of proportionality:

y = (5/2)x

Write an equation in slope-intercept form of the line shown.

7nadin3 [17]

Answer:

$y = 2x - 5$

Step-by-step explanation:

Find the slope using the points, (1, -3) and (3, 1):

$slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-3)}{3 - 1} = \frac{4}{2} = 2$

m = 2

Find the y-intercept (b) by substituting x = 1, y = -3, and m = 2 in $y = mx + b$

$-3 = (2)(1) + b$

$-3 = 2 + b$

Subtract 2 from both sides

$-3 - 2 = 2 + b - 2$

$-5 = b$

$b = -5$

Plug in the value of m and b into the slope-intercept form equation, $y = mx + b$ .

Thus:

$y = 2x +(-5)$

✅ $y = 2x - 5$
