Prove
 m∠5+m∠2+m∠6=180°

we have that
m∠1+m∠2+m∠3=180°   equation I

m∠1=m∠5  -------- > in<span>ternal alternate angles  equation 2
</span>
and

m∠6=m∠3-------- > internal alternate angles    equation 3

<span>I substitute  equation 2 and equation 3 in equation I</span>

m∠1+m∠2+m∠3=180°-------- > m∠5+m∠2+m∠6=180°------- > is ok

An inner city revitalization zone is a rectangle that is twice as long as it is wide. The width of the region is growing at a ra
Ket [755]

Answer:

The area is changing at the point of  \mathbf{61200 m^2/year}

Step-by-step explanation:

From the given information:

Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w

where;

L = length and w = width of the rectangle

Suppose the Length L is twice the width w

Then L = 2w --- (1)

From The area of a rectangle

A = L  × w

A = 2w  × w

A = 2w²

Taking the above differentiating with respect to time

\dfrac{dA}{dt }= 4w \times  \dfrac{dw}{dt} --- (2)

At the time t

\dfrac{dw}{dt}= 34 m \ per \ year ; w = 450 \ m

Replacing the values back into equation 2, we get:

\dfrac{dA}{dt }= 4 \times 450 \times 34

\mathbf{\dfrac{dA}{dt }= 61200 m^2/year}

Write two equations. the first equation should express the area of the square (a as a function of the length (l of a side. the s
Sergeu [11.5K]

Answer:

a = l²

v = s³

Step-by-step explanation:

The area of a rectangle is the product of its length and width. When that rectangle is a square, the length and width are the same. Here, they are given as "l". Then the area of the square is ...

a = l·l = l²

__

The volume of a cuboid is the product of its height and the area of its base. A cube of edge length s has a square base of side length s and a height of s. Then its volume will be ...

v = s·(s²) = s³

The two equations you want are ...

• a = l²

• v = s³
