WORTH 15 POINTS PLEASE ANSWER ASAP!! MY YOUNGER BROTHER NEEDS HELP ON THIS!!!!<br> ∧ω∧
xxTIMURxx [149]

Answer:

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

Step-by-step explanation:

Given:

Consider a rectangle ABCD as shown in the figure below where,

Area (ABCD) = 635 × 7 = 4445

Therefore length and width of a rectangle will be

LENGTH =635 = AB

WIDTH  = 7 = AD

To Find:

AE =?

EF = ?

FB = ?

Ar(EFGH)=?

Ar(ABCD) =?

Solution:

We know that area of the rectangle is given by

\textrm{Area of rectangle}= LENGTH\times WIDTH

\textrm{Area of rectangle ABCD}= 635\times 7=4445\ unit^{2}

Substituting the values we get

\textrm{Area of rectangle AEHD}= AE\times 7\\\\4200=AE\times 7\\\therefore AE=\dfrac{4200}{7}=600

Similarly for area rectangle FBCG,

\textrm{Area of rectangle FBCG}= FB\times 7\\\\35=FB\times 7\\\therefore FB=\dfrac{35}{7}=5

Now we have

AB = 635,

AE + EF + FB = 635\\\\600+EF+5=635\\\\EF=635 -605=30\\\therefore EF = 30

Similarly for area rectangle EFGH,

\textrm{Area of rectangle EFGH}= EF\times 7\\\\=30\times 7=210\ isunit^{2}

Therefore,

AD = 7 unit

AE = 600 unit

EF = 30 unit

FB = 5 unit

Ar(EFGH)= 210 unit²

Ar(ABCD)= 4445 unit²

What is the inverse of f(x)=(x-5)^2 for x greater or equal to 5 where function g is the inverse of function f
koban [17]

Answer:


y=\sqrt{x}+5

Step-by-step explanation:


The inverse of a function, is the function or rule formed by reflecting the line over y=x. This means essentially that all (x,y) values from the original function switch to (y,x).


(x,y)--->(y,x) in the new function.


If the function has points (-3,4) and (5,-2) then the inverse has points (4,-3) and (-2, 5).


We can find the equation of the inverse by switching x and y in the equation and solving for y.

This means that y=(x-5)^2 becomes x=(y-5)^2. We now solve for y through inverse operations.

x=(y-5)^2

x=(y-5)^2\\\sqrt{x} =\sqrt{(y-5)^2} \\\sqrt{x} =y-5\\\sqrt{x} +5=y
