Write each vector in component form

Mathematics
1 answer:
meriva3 years ago
5 0
Answer to problem 1 is (9,9)
Answer to problem 2 is (0,-4)

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

Explanation:

To find the component form, they basically want the translation rule. To find the translation rule, we subtract the coordinates tip - head

In general, if we have two vectors M and N such that
M = (a,b)
N = (c,d)
then
vector MN = (c-a, d-b)

Applying this to the vector CD gives us
vector CD = (7-(-2), 10-1) = (7+2, 10-1) = (9, 9)
Basically meaning that we shift point C nine units to the right and nine units up to get to point D

Similarly,
vector RS = (-4-(-4), -3-1) = (-4+4, -3-1) = (0,-4)
so we shift point R four units down to get to point S

The domain of all step functions is all real numbers<br> true or false
Mariana [72]

Solution:

The domain of all step functions is all real numbers :True

As we know that the domin of a function is defined as the set of values of the variable for which the given function is defined.


Irrespective of the kind of function, domain will be always real numbers.

Hence in our case of step function, the domain will be real numbers only.

Hence the domain of the all the steps functions is all real numbers  only.

Need help idk how to slove this
Gemiola [76]

Hi!

I'm not sure how to slove this, but I do know how to solve it ;D

<h3>We can't know the exact value of y, but we can isolate y on one side. First, multiply by z on both sides. </h3>

\frac{x+y}{z*z}=3*z

x + y = 3 * z

<h3>Now subtract x from both sides.</h3>

x - x + y = 3 * z - x

<u>y = 3 * z - x</u>

<h2>The answer is y = 3 * z - x</h2>

Hope this helps! :)

Write an equation of the line with a slope of -3 and y-intercept of 0
klemol [59]

Answer:

y=-3x

Step-by-step explanation:

Slope intercept form is written as y=mx+b, where:

m= slope

b= y-intercept

We know the slope and y intercept already, so simply plug them in:

y=-3x+0

We can remove the +0 because it is redundant, therefore the final answer is:

y=-3x
