The unit vector that is in the same direction as v is given by:

$u = \left$

<h3>How to find a vector given two points?</h3>

The vector is given by the <u>terminal point subtracted by the initial point,</u> hence:

v = (-17, 4) - (7, -9) = <-24, 13>

<h3>How to find the unit version of a vector?</h3>

Each coordinate of the vector is <u>divided by it's norm</u>.

For this vector, the norm is given by:

$|v| = \sqrt{(-24)^2 + (13)^2} = \sqrt{745}$

Hence the unit vector is:

$u = \left$

Kaylib’s eye-level height is 48 ft above sea level, and addison’s eye-level height is 85 and one-third ft above sea level. how m

The addison see to the horizon at 2 root 2mi.

We have given that,Kaylib’s eye-level height is 48 ft above sea level, and addison’s eye-level height is 85 and one-third ft above sea level.

We have to find the how much farther can addison see to the horizon

<h3>Which equation we get from the given condition?</h3>

$d=\sqrt{\frac{3h}{2} }$

Where, we have

d- the distance they can see in thousands

h- their eye-level height in feet

For Kaylib

$d=\sqrt{\frac{3\times 48}{2} }\\\\d=\sqrt{{3(24)} }\\\\\\d=\sqrt{72}\\\\d=\sqrt{36\times 2}\\\\\\d=6\sqrt{2}....(1)$

For Addison h=85(1/3)

$d=\sqrt{\frac{3\times 85\frac{1}{3} }{2} }\\d\sqrt{\frac{256}{2} } \\d=\sqrt{128} \\d=8\sqrt{2} .....(2)$

Subtracting both distances we get

$8\sqrt{2}-6\sqrt{2} =2\sqrt{2}$

Therefore, the addison see to the horizon at 2 root 2mi.

The function ƒ(x) = 6x is vertically shrunk by a factor of ½ and translated 9 units in the negative y- direction. Select the cor

vredina [299]

Answer:

option C.

Step-by-step explanation:

since the graph y = 6x is shrunk by a factor of ½

it becomes y = 3x

to find one coordinate of this graph we put x = 1 so that we get y = 3

so one point we have is (1, 3).

and the other point is origin

[ for if you keep x = 0 then 3 × 0 = 0 so y comes 0 too.]

now this graph is translated 9 units in the negative y direction

so the point that initially was (0, 0) now becomes (0, -9).

we see that the only graph passing thru (0, -9) is C.

so the answer is <u>option C.</u>

Tariq is comparing the prices of various packages of golf tees at a sporting goods store. He finds a package of 8 golf tees that

Alenkasestr [34]

Answer:

$0.25

Step-by-step explanation:

To find unit rate divide number of shirts by cost of package

$2.00/8 = $0.25

So each individual golf tee costs $0.25

3 ( 8m+5) = 4 (6m+7)-13

Kitty [74]

Answer:

infinite solutions

Step-by-step explanation:

Given

3(8m + 5) = 4(6m + 7) - 13 ← distribute parenthesis on both sides

24m + 15 = 24m + 28 - 13 , that is

24m + 15 = 24m + 15

Since both sides are equal then any real value of x makes the equation true.

Thus there are an infinite number of solutions

Find the length of x round your answer to the nearest hundredth

allsm [11]

Answer:

x = 7.55

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2 +8^2 = 11^2

x^2 +64 = 121

Subtract 64 from each side

x^2 +64-64 = 121-64

x^2 =57

Take the square root of each side

sqrt(x^2) = sqrt(57)

x = 7.549834435

To the nearest hundredth

x = 7.55
