If the width of the reactangle is x=13, the area of the rectangle is:
A(13)=2*(13)^2-5*(13)
A(13)=2*(169)-65
A(13)=338-65
A(13)=273
The area of the rectangle is 273 square units
8,15,17 represents
(17)^2=289
(15)^2=225
(8)^2=64
i.e. (17)^2=(15)^2+(8)^2
By converse of Pythagoras theorem
This ∆ is a right angled ∆
Answer:
0.531 (3 s.f.)
Step-by-step explanation:

Power rule is used for the 3rd step.
The value of f(a)=4-2a+6
, f(a+h) is
, [f(a+h)-f(a)]/h is 6h+12a-2 in the function f(x)=4-2x+6
.
Given a function f(x)=4-2x+6
.
We are told to find out the value of f(a), f(a+h) and [f(a+h)-f(a)]/hwhere h≠0.
Function is like a relationship between two or more variables expressed in equal to form.The value which we entered in the function is known as domain and the value which we get after entering the values is known as codomain or range.
f(a)=4-2a+6
(By just putting x=a).
f(a+h)==
=4-2a-2h+6(
)
=4-2a-2h+6
=
[f(a+h)-f(a)]/h=[
-(4-2a+6
)]/h
=
=
=6h+12a-2.
Hence the value of function f(a)=4-2a+6
, f(a+h) is
, [f(a+h)-f(a)]/h is 6h+12a-2 in the function f(x)=4-2x+6
.
