An 18 foot tall pole casts a shadow that is 28.8 feet long. At the same time a woman casts a shadow that is 8.8 feet long how ta

Alex73 [517]

Answer:

5.5 ft tall

Step-by-step explanation:

The shadows cast by the pole and by the woman form <em>similar triangles</em>.

In similar triangles, corresponding sides are in the same proportion.

Thus,

18/28.8 = x/8.8

Multiply each side of the equation by 8.8

x = 8.8 × 18/28.8 = 5.5 ft

The woman is 5.5 ft tall.

Solve for the roots in simplest form by completing the square <br> 6x^2+120x+2070=0

Kitty [74]

Answer:

Step-by-step explanation:

First, we can divide out the common factor, 6

$6x^2 + 120x + 2070 = 0\\x^2 + 20x + 345 = 0\\$

Now we complete the square

$(x^2 + 20x + (\frac{20}{2})^2) + 345 - (\frac{20}{2})^2\\(x^2 + 20x + 100) + 345 - 100\\(x+10)^2 + 245\\$

$(x+10)^2 = -245\\x + 10 = \sqrt{-245}\\x = i\sqrt{245} - 10\\x = -10 \pm i\sqrt{245}$

a laptop computer is purchased for $4500. Each year, its value is 80% of its value the year before. After how many years will th

motikmotik

Answer:

So after 7 year price of the laptop will be less than $1000

Step-by-step explanation:

We have given price of the laptop is $4500

Its price is 80% of if its value in every next year

So depreciation rate = 100 - 80 =20%

For depreciation we know that

$V=P(1-r)^n$

Here V is final value and P is present value

So $1000=4500(1-0.2)^n$

$0.2222=(0.8)^n$

Taking log both side

$log0.222=nlog0.8$

n = 6.74

So after 6.74 year the price of the laptop will be less than $1000
