Answer:

f^-1 (x)=x^2-4x+1

Step-by-step explanation:

y=sqrt(x+3)+2

x=sqrt(y+3)+2

sqrt(y+3)=x-2

y+3=(x-2)^2

y+3=(x-2)(x-2)

y+3=x^2-2x-2x+4

y+3=x^2-4x+4

y=x^2-4x+4-3

y=x^2-4x+1

FrozenT [24]

Answer:

68%

Step-by-step explanation:

Calculate percentage change

from V1 = 82 to V2 = 138

(V2−V1)|V1|×100

=(138−82)|82|×100

=5682×100

=0.682927×100

=68.2927%change

=68.2927%increase

=68%

Answer:

Step-by-step explanation:

by looking at the given image...

the shape ABCD is a parallelogram.

<u>Required:</u>

is to prove ∡A and ∡B are supplementary

and ∡C and ∡D are supplementary.

so, m∠A + m∠B = 180°

and m∠C + m∠D = 180°

<u><em>the Statement </em></u>

1. ABCD is a parallelogram

<em><u>the reason is..</u></em><em> </em>

It is Given!

<u><em>the Statement </em></u>

2.m∠A=m∠C and m∠B=m∠D

<em><u>the reason is..</u></em><em> </em>

Definition of parallelogram.

<u><em>the Statement </em></u>

3.m∠A+m∠B+m∠C+m∠D=360°

<em><u>the reason is..</u></em><em> </em>

Definition of quadrilateral

<u><em>the Statement </em></u>

4. m∠A+m∠B+m∠A+m∠B=360°

<em><u>the reason is..</u></em><em> </em>

By substitution

⇒ 2( m∠A + m∠B ) = 360°

⇒ m∠A + m∠B = 180°

it is also similar m∠C + m∠D = 180°

<u><em>the Statement </em></u>

5.∠A and ∠C are supplementary

<em><u>the reason is..</u></em><em> </em>

by the definition of Supplementary ∠ B and ∠D are supplementary

Hope it helps!
