The graph shows g(x), which is a translation of f(x)=|x|. Write the function rule for g(x).

Kay [80]

Answer:

g(x) = |x| -9

Step-by-step explanation:

In the form ...

g(x) = a|x -h| +k

the parameters are ...

a: the vertical scale factor (1)
h: the right shift of the vertex (0)
k: the upward shift of the vertex (-9)

The vertex of |x| is (0, 0). The vertex of g(x) is (0, -9), so there has been a vertical shift of -9 and no horizontal shift. The slopes of the lines on the graph of g(x) have a magnitude of 1, so the vertical scale is not changed from the original function (a=1).

Then the translated function is ...

g(x) = |x| -9

Find the angle θ between ???? and ???? if ????⋅????=12‖????‖⋅‖????‖. (Use symbolic notation and fractions where needed. Give you

BlackZzzverrR [31]

Answer: hello your question is poorly written below is the complete question

Find the angle between and if ⋅=3√2‖‖⋅‖‖.

(Use symbolic notation and fractions where needed. Give your answer in terms of . )

answer :

∅ = π / 6

Step-by-step explanation:

V .W = $\frac{\sqrt{3} }{2} || V ||. ||W||$

Hence

∅ = cos^-1 ( $\frac{\frac{\sqrt{3} }{2} || V ||. ||W||}{||V||.||W||}$

∅ = cos^-1 ( $\frac{\sqrt{3} }{2}$ )

∴ ∅ = π / 6

Quadrilateral WXYZ has vertices W(-4,-3), X(0,-1). Y(6,-2), Z(2,-4). Using properties of diagonals prove that WXYZ is a parallel

yanalaym [24]

Answer:

The diagonals are bisectors of each other and meet at (1, -5/2) but are not congruent, so WXYZ is a parallelogram and not a rectangle

Step-by-step explanation:

for parallelograms.

the diagonals intersect at the midpoints

W X

Z Y

Diagonals are WY and XZ

WY : (-4, -3) to (6, -2)

midpoint is [(-4 + 6)/2 , (-3 - 2)/2 ] = ( 1, -5/2 )

XZ : (0, -1) to (2, -4)

midpoint is [ (0 + 2)/2 , (-1 + -4)/2 ] = (1, -5/2)

The diagonals are bisectors of eachother.

Next show that these diagonals are not congruent.

length of WY = root ( (-4 - 6)^2 + (-3 - (-2))^2 )

WY = root ( 100 + 1)

WY = root(101)

length of XZ = root ( (0 - 2)^2 + ( -1 - -4)^2 )

XZ = root (4 + 9) = root (13)

we see that WY is not equal to XZ

...

so .. quadrilateral WXYZ is a parallelogram but not a rectangle.
