A daim duab (los yog puab ) uas tuaj yeem muab faib ua ntau tshaj ib qho ntawm qhov pib cov duab hais tias yog ib composite daim duab (los yog puab ). Piv txwv li, daim duab ABCD yog ib daim duab sib xyaw raws li nws muaj ob qho yooj yim cov duab . Qhov ntawd yog, fig yog tsim los ntawm ib daim duab plaub thiab daim duab peb sab raws li qhia hauv qab no.
Hais txog qhov no, puas yog ib qho trapezoid ib daim duab sib xyaw?
Nyob rau hauv ntau zaus, geometric daim duab yog tsim los ntawm ntau yam sib txawv cov duab , xws li daim duab peb sab, quadrilaterals, voj voog, thiab lwm yam. Xws li ib daim duab npe a composite daim duab . Cov daim duab yog ib tug trapezoid , tab sis xav txog lub sijhawm uas koj tsis nco qab cov qauv rau thaj tsam ntawm a trapezoid.
Ib yam li ntawd, tus qauv rau cheeb tsam yog dab tsi? Qhov yooj yim tshaj plaws cheeb tsam formula yog cov qauv rau cov cheeb tsam ntawm ib daim duab plaub. Muab ib daim duab plaub nrog ntev l thiab dav w, lub qauv rau cov cheeb tsam is: A = lw (rectangle). Ntawd yog, lub cheeb tsam ntawm daim duab plaub yog qhov ntev multiplied los ntawm qhov dav.
Tib neeg kuj nug, dab tsi yog qhov ib puag ncig ntawm daim duab sib xyaw?
A composite daim duab yog tsim los ntawm cov duab peb sab, squares, rectangles, semicircles, thiab lwm yam ob-dimensional cov duab . Nov yog ob qho piv txwv. Yuav nrhiav tau perimeter ntawm ib daim duab composite , nrhiav qhov deb nyob ib ncig ntawm daim duab . Cov ib puag ncig Luas = 20 + 12 = 32 cm.
Dab tsi yog thaj tsam ntawm lub trapezoid no?
Thaj chaw ntawm a Trapezoid Formula. Kev sib faib lub sij hawm 12 yog tib yam li kev faib los ntawm 2. Peb muab ib nrab ntawm qhov ntev ntawm ob lub hauv paus (lawv qhov nruab nrab) thiab tom qab ntawd muab faib los ntawm qhov siab, lossis qhov siab, txhawm rau nrhiav qhov siab. cheeb tsam nyob rau hauv square units.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Yuav ua li cas yog ib co piv txwv ntawm volcanoes composite?
Cov piv txwv nto moo ntawm cov pob zeb sib xyaw yog Mayon Volcano, Philippines, Mount Fuji hauv Nyij Pooj, thiab Mount Rainier, Washington, Asmeskas Qee qhov sib xyaw volcanoes ncav cuag ob txog peb txhiab meters hauv qhov siab tshaj lawv cov hauv paus. Feem ntau cov volcanoes sib xyaw tshwm sim nyob rau hauv chains thiab sib cais los ntawm ob peb kaum kilometers
Yuav ua li cas koj multiply composite functions?
Multiplication and Composition of Functions Yuav kom muab ntau txoj haujlwm los ntawm tus lej, muab txhua qhov tso tawm los ntawm qhov ntsuas ntawd. Thaum peb coj f (g(x)), peb muab g(x) raws li cov tswv yim ntawm kev ua f. Piv txwv li, yog f (x) = 10x thiab g(x) = x + 1, ces nrhiav f (g(4)), peb nrhiav g(4) = 4 + 1 + 5, thiab ces ntsuas f (5. ) = 10(5) = 50. Example: f(x) = 2x - 2, g(x) = x2 - 8
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
