Inverse proportion . Inverse proportion tshwm sim thaum ib tug nqi nce thiab lwm yam txo. Rau piv txwv , ntau tus neeg ua haujlwm ntawm txoj haujlwm yuav txo lub sijhawm los ua kom tiav cov haujlwm. Lawv yog inversely proportional.
Tsis tas li ntawd, dab tsi yog qhov sib piv ntawm qhov sib txawv?
Inverse proportion yog kev sib raug zoo ntawm ob qhov sib txawv thaum lawv cov khoom sib npaug rau tus nqi tas li. Thaum tus nqi ntawm ib qho kev sib txawv nce, qhov qis dua, yog li lawv cov khoom tsis hloov pauv. y yog inversely proportional rau x thaum qhov sib npaug siv daim ntawv: y = k/x. los yog.
Tsis tas li ntawd, dab tsi yog qhov ncaj los yog qhov sib npaug? Hauv ncaj qha variation , raws li ib tug lej nce, yog li tus lwm. Qhov no kuj hu ua ncaj qha proportions : lawv yog tib yam. Hauv inverse variation , nws yog qhov sib txawv: raws li ib tus lej nce, lwm qhov txo qis. Qhov no kuj hu ua inverse proportions.
Tsis tas li ntawd, qhov piv txwv ntawm kev faib ncaj qha yog dab tsi?
Yog tias koj tuaj yeem muab thawj qhov ntau los ntawm tib tus lej (hu ua qhov tsis tu ncua) kom tau txais qhov thib ob, lawv nyob hauv ncaj qha proportions . Rau piv txwv , yog 1 ice-cream nqi $2, ces 2 ice-cream yuav raug nqi $4, 3 ice-cream nqi $6, 4 ice-cream yog $8 thiab hais txog.
Dab tsi yog lej txhais ntawm inverse?
Hauv lej , lus thim rov qab hais txog qhov ntxeev ntawm lwm txoj haujlwm. Cia peb saib qee qhov piv txwv kom nkag siab txog qhov lub ntsiab lus ntawm inverse . Piv txwv 1: Li no, qhov sib ntxiv thiab rho tawm yog cov haujlwm sib txawv. Peb yuav hais tias, rho tawm yog tus thim rov qab kev ua haujlwm ntxiv.

Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
