Andru [333]

Answer:

The tree is 28 feet tall.

Step-by-step explanation:

It is given that:

Height of flag pole = 8 feet

Shadow of flag pole = 6 feet

Ratio of height to shadow = 8 : 6

Shadow of nearby tree = 21 feet

Height of nearby tree = x

Ratio of height to shadow = x : 21

8 : 6 :: x : 21

Product of means = Product of extremes

6x = 8*21

6x = 168

Dividing both sides by 6

$\frac{6x}{6}=\frac{168}{6}\\x=28$

Therefore,

The tree is 28 feet tall.

lbvjy [14]

Answer:

The rate of change of area is 35360 m /year

Step-by-step explanation:

Let the width of rectangle be w

We are given that a rectangle that is twice as long as it is wide

So, Length of Rectangle = 2w

Area of rectangle A = Length \times Breadth = $w \times 2w= 2w^2$

Differentiating area with respect to time

$A=2w^2\\\frac{dA}{dt}=4w\frac{dw}{dt}$

We are given that $\frac{dw}{dt} = 34m/year$ and w = 260

$\frac{dA}{dt}=4(260)(34)=35360$

Hence the rate of change of area is 35360
