Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, projvu u=(-8,8) , v= (

Jobisdone [24]

Answer:

none of the given options is true

Step-by-step explanation:

Given: u=(-8,8) , v= (-1,2)

To find: vectors $w_1,w_2$ such that $u=w_1+w_2$

Solution:

A vector is a quantity that has both magnitude and direction.

$proj_vu=\frac{u\cdot v}{\left | v \right |^2}(v)\\=\frac{(-8,8)\cdot (-1,2)}{(\sqrt{ (-1)^2+2^2})^2}(-1,2)\\=\frac{8+16}{5}(-1,2)\\=\frac{1}{5}(-24,48)\\=(-4.8,9.6)$

Let $w_1=(-4.8,9.6)$

So,

$w_2=u-w_1\\=(-8,8)-(-4.8,9.6)\\=(-8+4.8,8-9.6)\\=(-3.2,-1.6)$

So, u = $(-4.8,9.6)+(-3.2,-1.6)$

So, none of the given options is true

What's the slope?? <br><br> Thank you!!! :)))

Alja [10]

Answer:

The slope of this line is 4

Step-by-step explanation:

The slope is determined with two points.

Take the pairs (0, - 9) and (1, - 5).

The slope is:

m = (y₂ - y₁) / (x₂ - x₁) = (- 5 - (-9)) / ( 1 - 0) = 4/1 = 4

What are the domain and range of f(x) = (1/6)^x + 2?

Setler [38]

Answer: The domain of f(x) is all real numbers, $(-\infty,\infty)$ and range of f(x) is $(2,\infty)$ .

Explanation:

The given function is,

$f(x)=(\frac{1}{6})^x+2$

The domain is the set of all possible values for which the value of function exist.

The given function is defined for any real value of x, therefore the domain of the function is set of all real number. it can be written in interval notation $(-\infty,\infty)$ .

The range is the set of possible value of f(x) at different value of x. Range is the set of outputs.

In the given function,

$(\frac{1}{6})^x>0$

for any value of x.

So,

$(\frac{1}{6})^x+2>0+2$

$f(x)>2$

Therefore the value of f(x) is always greater than 2 and the range of the function is $(2,\infty)$ .
