Best ResponseYou've already chosen the best response.3you are given she is 6 miles away from the shuttle launch

Best ResponseYou've already chosen the best response.3use the given and the thing you want to find to express a trigonometric equation to solve

Best ResponseYou've already chosen the best response.3for example you are given the adjacent side to the angle given and you are ask to find the opp site this just screams what trig ratio?

Best ResponseYou've already chosen the best response.0I honestly have no idea... I don't even what a trigonometric ratio is

Best ResponseYou've already chosen the best response.3that is weird so you never heard so sin,cos,tan,csc,sec,cot?

Best ResponseYou've already chosen the best response.0I know sin cos and tan

freckles

Best ResponseYou've already chosen the best response.3and do you know that tan(of an angle) is the opposite side of that angle divided by the adjacent side of that angle?

Best ResponseYou've already chosen the best response.3ok so that is the trigonometric ratio you want to use

Best ResponseYou've already chosen the best response.1here is an easy solution if you know tan and sindw:1436226242655:dw use the angle of 10 with the tan ratio

freckles

Best ResponseYou've already chosen the best response.3notice as I said before you are given the adjacent side and looking for the opposite side of the angle 80 deg

Best ResponseYou've already chosen the best response.3the sum of the angles of a triangle equal 180 deg

Best ResponseYou've already chosen the best response.0so would it be 80/10

Best ResponseYou've already chosen the best response.3tan(80)=(opp SIDE of angle with measurement 80) divided by (adj SIDE of angle with measurement 80)

Best ResponseYou've already chosen the best response.3dw:1436226787960:dw \[\tan(80^o)=\frac{\text{ opp side }}{\text{ adj side }} \]dw:1436226852206:dw can you identify the sides that are opposite and adjacent ?

Best ResponseYou've already chosen the best response.0opposite  10 ? adjacent  6 ?

Best ResponseYou've already chosen the best response.3adjacent is right but how are you getting the opp is 10?

Best ResponseYou've already chosen the best response.3\[\tan(80^o)=\frac{x}{6}\] great now solve this for x

anonymous

Best ResponseYou've already chosen the best response.0How do i solve for x

freckles

Best ResponseYou've already chosen the best response.3you undo the division there by x do you see that x is being divided by 6?

freckles

Best ResponseYou've already chosen the best response.3try multiplying by 6 on both sides to get x by itself

anonymous

Best ResponseYou've already chosen the best response.0would it be tan80 * 6?

freckles

Best ResponseYou've already chosen the best response.3yes x=6*tan(80) just whip out your calculator and type that in to find what x is

Best ResponseYou've already chosen the best response.3I would probably round to 34.03 since there is a 7 behind that 2

Best ResponseYou've already chosen the best response.0yea sorry about that lol

freckles

Best ResponseYou've already chosen the best response.3you could have used the angle mentioned by campbell too

freckles

Best ResponseYou've already chosen the best response.3the setup would have looked different but should end up with same answer

Best ResponseYou've already chosen the best response.3\[\tan(10^o)=\frac{6}{x} \\ \frac{1}{\tan(10^o)}=\frac{x}{6} \\ \frac{6}{ \tan(10^o)}=x\]

freckles

Best ResponseYou've already chosen the best response.3this also gives you 34.03

Best ResponseYou've already chosen the best response.0can you tell me what geometric mean is

freckles

Best ResponseYou've already chosen the best response.3oh the geometric mean of a and b is : \[\sqrt{a \cdot b}\] in general the geometric means of \[x_1,x_2,... ,x_n \text{ is } \sqrt[n]{x_1 \cdot x_2 \cdots x_n}\]

anonymous

Best ResponseYou've already chosen the best response.0Find the geometric mean between 14 & 21. this is the questoin

freckles

Best ResponseYou've already chosen the best response.3well that fits in with that first formula nicely since like that one you have two numbers

freckles

Best ResponseYou've already chosen the best response.3just replace a with 14 and b with 21

freckles

Best ResponseYou've already chosen the best response.3that is right but that could be simplified I would have left 294 as 21*14 and looked for perfect square factors for example I know 21=7*3 and 14=7*2 so 21*14=2*3*7^2 and you know the square root of 7^2 (aka 49) \[\sqrt{21 \cdot 14} \\ =\sqrt{7^2 \cdot 2(3)} \\ =\sqrt{7^2} \sqrt{2(3)}\]

Best ResponseYou've already chosen the best response.0Select one: a. 103√ or appx. 17.3 b. 17.5 c. 76√ or appx. 17.1 d. 637/35 or appx. 18.2 these are the answers

freckles

Best ResponseYou've already chosen the best response.3can't read those answers too well but if you are looking for an approximation instead of a simplified exact answer then plug in sqrt(14*21) into your calculator

Best ResponseYou've already chosen the best response.3just curious you don't know the sqrt(7^2)?
