Best ResponseYou've already chosen the best response.1for the first part we need to find max in other words vertex point dw:1443039751009:dw

Best ResponseYou've already chosen the best response.1so use the formula to find ccoordinate of the vertex \[\huge\rm x=\frac{ b }{ 2a }\] b=middle term a=leading coefficient

Best ResponseYou've already chosen the best response.1don't forget the sign okay \[\frac{ 0.658 }{ 2(0.00407) }\] now solve

Best ResponseYou've already chosen the best response.1something wrong i didn't get that o.O

Best ResponseYou've already chosen the best response.0I typed it in my ti84 calculator, that's what I got..

Best ResponseYou've already chosen the best response.1try again put the parentheses

Best ResponseYou've already chosen the best response.1that's how you should type in ti 84 (.658)/(2(.000407))

Best ResponseYou've already chosen the best response.0\[(\frac{ .658 }{ 2(.000407) }= 808.3538084\]

Best ResponseYou've already chosen the best response.1yes right now that's x coordinate of vertex now substitute x for 808 to find ycoordinate into the original equation

Best ResponseYou've already chosen the best response.1hmm i mean \[y=.000407x^2+.658x\] in this equation replace x with 808

Best ResponseYou've already chosen the best response.1yes right we can round it so it would be 266 that would be the height

Best ResponseYou've already chosen the best response.1now for the 2nd part you need to find xintercept(zeros ) of that quadratic equation

Best ResponseYou've already chosen the best response.1i'll like to use quadratic formula bec there are negative numbers

shaleiah

Best ResponseYou've already chosen the best response.0I'm not good at quadratic formulas:(

Nnesha

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ b \pm \sqrt{b^24ac} }{ 2a }\] quadratic formula a= leading coefficient b=middle term c=constant so justplugin

Nnesha

Best ResponseYou've already chosen the best response.1\[\huge\rm Ax^2+Bx+C\] quadratic equation a= leading coefficient b=middle term c=constant

Best ResponseYou've already chosen the best response.0\[\frac{ .658 +\sqrt{.658^{2}4(.00407)}}{ 2(266) }\]

Nnesha

Best ResponseYou've already chosen the best response.1don't forget the C which is 0 so 4ac would be 4(.000407)(0) and why did you replace a with 266 ?

Nnesha

Best ResponseYou've already chosen the best response.1the denominator is 2a so 2(????)

Nnesha

Best ResponseYou've already chosen the best response.1yes right \[\frac{ .658 +\sqrt{(.658)^{2}4(.00407)(0)}}{ 2(.000407) }\] now oslve

Nnesha

Best ResponseYou've already chosen the best response.1please show you u got that that's not right you should get 2 solutions

shaleiah

Best ResponseYou've already chosen the best response.0I typed the equation directly in my ti84 calculator

shaleiah

Best ResponseYou've already chosen the best response.0Do i solve them seperately?

Nnesha

Best ResponseYou've already chosen the best response.1hmm that wouldn't work how would you right plus minus sign in the calculator yes right solve the numerator the square root part

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.1both are wrong first solve square root \[\frac{ .658 +\sqrt{\color{ReD}{(.658)^{2}4(.00407)(0)}}}{ 2(.000407) }\] now just type the red part into the calculator

Nnesha

Best ResponseYou've already chosen the best response.1i just realized i'm the one who typed incorrectly sorry it's plus/minus \[\frac{ .658 \pm \sqrt{\color{ReD}{(.43296)}}}{ 2(.000407) }\]

Nnesha
 one year ago
Best ResponseYou've already chosen the best response.1take the square root of .43296

Nnesha

Best ResponseYou've already chosen the best response.1right so \[\huge\rm \frac{ .658+6.58 }{ 2(.000407) } and \frac{ .658.658 }{ 2(.000407) }\] now we can seprate plus and minus sign and i found another typo a=negative .000407

Nnesha

Best ResponseYou've already chosen the best response.1that is same as .658 remember the number after 7 is greater than 5 so you can round it

Nnesha

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ .658+6.58 }{ 2(.000407) } and \frac{ .658.658 }{ 2(.000407) }\] alright work on this brb

Best ResponseYou've already chosen the best response.1there are two fraction what did you get for first one what did you get for 2nd one

Nnesha

Best ResponseYou've already chosen the best response.1that doesn't looks right

shaleiah

Best ResponseYou've already chosen the best response.0are you sure the equation is set up correctly?

Nnesha

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ .658+6.58 }{ 2(.000407) } and \frac{ .658.658 }{ 2(.000407) }\] yes this one is 100% correct

shaleiah

Best ResponseYou've already chosen the best response.0The first fraction is: 7275... The second fraction is: 807545

Nnesha

Best ResponseYou've already chosen the best response.1ugh first fraction is .658 .658 not (6.58) 2nd fraction is 100% right but no ur answer is not right for 2nd one

Nnesha

Best ResponseYou've already chosen the best response.1tell me what did you type into the calculator for first fraction

shaleiah

Best ResponseYou've already chosen the best response.0The 6.58 was the error :(

Best ResponseYou've already chosen the best response.1\[\huge\rm \frac{ .658+.658 }{ 2(.000407) } \] first one

Nnesha

Best ResponseYou've already chosen the best response.1right what about other one

Nnesha

Best ResponseYou've already chosen the best response.1hmm not correct what did you type into the caluclator ?

shaleiah

Best ResponseYou've already chosen the best response.0I'm sorry :/ I see the error. I re typed it and I got 1616.707617

Best ResponseYou've already chosen the best response.0Did we finish all the steps?

Nnesha

Best ResponseYou've already chosen the best response.1yep that's for 2nd part!

Nnesha

Best ResponseYou've already chosen the best response.12nd one is `how long` so it would be 1616.71 0 wouldn't be the answer
