A)

Let h represent the height of the flagpole. 

When the angle of elevation is 62°, tan(62°) = h/x   --->   x  =  h/tan(62°)

When the angle of elevation is 48°, tan(48°) = h/(x+16)   --->   x + 16  =  h/tan(48°)   --->   x  =  h/tan(48°) - 16

B)

Since there are two equations for x, they can be set equal to each other.

h/tan(62°)  =  h/tan(48°) - 16

h/1.8807  =  h/1.1106 - 16           (since 1/1.8807 = 0.5317  and  1/1.1106 = 0.9904)  --->

0.5317h  =  0.9004h - 16             (subtract 0.9004 from both sides)  --->

- 0.4587h  =  -16                           (divide both sides by -0.4587)  --->

h  =  35 feet (approximately)

thanks for the cake........i really wanted to have some...........soon a disease called "exams" is going to take over me..they say , this disease somes to people who are great and are soon to get a throne, as you know how great i am , and soon ill be getting Camelot , so due to these , this disease is coming over me....its sad you cant suffer from it............dont be sad....we all have those days.....

dont worry...ill give you a nice job in my empire.......as respectable as a dishwasher ......

Such as? Give me an example

-13 from both sides so

x/8=4

multiply both sides by 8

so x=32 

Camera costs $300 

she saves $15 each week 

in how many weeks will she have enough money for the camera?

300/15=20 so in 20 weeks

the equation algebraically is 

Let C denote the cost of the camera 

let W denote the amount she saves each week 

C/W=number of weeks 

There is no real fourth root to -16/81.

It does have an imaginary (complex) root of 2/3i; but no real root.

It does have a real fourth power:  (-16/81)⁴  =  65536/43046721.

It's already real and it can't be simplified any further.

Wow,,i am so dumb!!!

i didnt even remeber that i was ever mad at you...i have no idea about getting mad at you not wishing.....seriously....

its ok!do you think im such a monstrous witch to remeber that till now?bro, ive got all to think about...i cnat keep this in my head till the day i die.....

anyways....HAPPY BELATED BIRTHDAY,,,,,dear ......enemy or friend......

i hope it went AWESOME

how are you now ? (how much ever, youll still be my junior HAHAHAHA)

heres your gift...my two favorite things...now yours!!

7 hours reading each week

6 hours of watching tv each week

4 hours of playing outside each week

The associative property of addititon is (a+b)+c=a+(b+c)

let 7 = a

let 6 = b

let 4 = c

so you have (7+6)+4=7+(6+4)

the two expressions are (7+6)+4 and 7+(6+4) 

(7/2)^36 = 38587762477395204358.3125251694727922

She has 2 left

atan(2) = 1.107148717794

atan(2)=63.434948822922

Do arc tan or tan^-1 so that tan(2)^-1=x but i'm not sure if you're talking in degree's or radians.

if the balance at the end of eight years on an investment of $630 that has been invested at a rate of 9% is $1,083.60, how much was the interest.

If the $630 was invested for 8 years @ 9% comp. annually, the $630 should have have grown to $1,255.31 and NOT $1,083.60. This means there had to be a withrawal of $1,255.31 - $1,083.60=$171.71 sometime in that 8-year period. $1,083.60 would be the amount you would expect to receive @ about 7% and NOT 9%. At any rate, whtaever the final balance is supposed to be, $1,255.31 or $1,083.60, you simply subtract the original $630 from it and you get the interest.

im in english...and history....

science...physics chemistry biolong....just not my thing.....

coldplay...i dont know about being a zombie...but im definitely sure im a vampire.......what do you think about that hun? 

its good to be here too melody. my exams are starting so idk if this would be often. i just thought to make a post so that im not declared dead and someone else comes and take Camelot coz....it it MINE!!!! and will always be.....hehe

thanks melody....i really worked heard to get it.....lol
