Lus txhais: Standard Form : cov txheem daim ntawv ntawm ib kab yog nyob rau hauv daim ntawv Ax + By = C qhov twg A yog tus lej zoo, thiab B , thiab C yog cov lej. Cov txheem daim ntawv ntawm ib kab yog lwm txoj hauv kev sau qhov sib npaug ntawm kab.
Tib neeg kuj nug, A thiab B sawv cev rau dab tsi hauv daim qauv?
Standard Form [edit] Txheem daim ntawv yog lwm txoj hauv kev los sau nqes hav-intercept daim ntawv (as opposed to y=mx+ b ). A, B C yog integers (tus lej zoo lossis tsis zoo tag nrho) Tsis muaj feem lossis cov lej hauv txheem daim ntawv . Lub sij hawm "Ax" yog qhov zoo.
Tsis tas li ntawd, dab tsi yog tus qauv hauv daim ntawv parabola? f (x) = a(x - h)2 + k, qhov twg (h, k) yog lub vertex ntawm tus parabola . FYI: Cov phau ntawv sib txawv muaj kev txhais lus sib txawv ntawm kev siv " txheem daim ntawv Ib txhia hais tias f (x) = ax2 + bx + c yog " txheem daim ntawv ", thaum lwm tus hais tias f (x) = a(x - h)2 +k yog " txheem daim ntawv ".
Ib yam li ntawd, tus A sawv cev li cas hauv daim qauv?
Txhua tsab ntawv nyob rau hauv txheem daim ntawv kab zauv qhia peb ib daim ntawm cov ntaub ntawv hais txog lub parabola, ib yam li cov ntawv ntawm lub vertex daim ntawv equation muaj. Hauv txheem daim ntawv tus nqi "a". sawv cev tib yam li nws ua hauv vertex daim ntawv . Ib yam li hais ua ntej, nws dictates cov kev taw qhia ntawm parabola qhib.
Ib qho piv txwv ntawm cov qauv qauv yog dab tsi?
Txheem daim ntawv yog ib txoj hauv kev sau cov lej loj lossis tsawg heev yooj yim. 103 Luas = 1000, 4 × 103 = 4000. Yog li 4000 tuaj yeem sau ua 4 × 10³. Cov lej me tuaj yeem sau rau hauv txheem daim ntawv.
Pom zoo:
C sawv cev rau dab tsi hauv daim qauv?
Standard Form: daim ntawv qauv ntawm ib kab yog nyob rau hauv daim ntawv Ax + By = C qhov twg A yog ib tug zoo integer, thiab B, thiab C yog integers
Cov duab ntxoov ntxoo sawv cev li cas hauv daim ntawv qhia pedigree?
Daim duab qhia txog kev sib raug zoo hauv tsev neeg, yog siv. Nyob rau hauv ib tug pedigree, lub voj voog sawv cev rau ib tug poj niam, thiab lub square sawv cev rau ib tug txiv neej. Ib lub voj voog lossis square qhia tau hais tias tus neeg muaj tus cwj pwm uas tau kawm. Kab rov tav uas txuas lub voj voog thiab ib lub xwmfab sawv cev rau kev sib yuav
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Vim li cas cov qauv hauv daim duab 1 homologous cov qauv?
Lub xub ntiag ntawm homologous qauv qhia tau hais tias cov kab mob hloov zuj zus los ntawm cov poj koob yawm txwv. 1. Xa mus rau daim duab 1. Siv cov ntaub ntawv Table 1, Qhia qhov tseeb ntawm lub cev qhia rau txhua yam kab mob uas tau teev tseg
