Tus s hauv Heron tus qauv qhia txog qhov ib puag ncig ntawm ib daim duab peb sab, uas nws cheeb tsam yuav tsum tau ntsuas. Semi-perimeter yog sib npaug rau tus lej ntawm tag nrho peb sab ntawm daim duab peb sab muab faib los ntawm 2.
Dab tsi yog qhov ib puag ncig ntawm Heron tus qauv?
Siv Semi perimeter ntawm daim duab peb sab
Nws muaj lo lus "s" uas sawv cev rau ib puag ncig ib puag ncig, uas tau los ntawm kev faib cov cheeb tsam ntawm daim duab peb sab los ntawm ob. Heron tus qauv qhia tau hais tias, √[s(s-a)(s-b)(s-c), qhov twg 's'=Semi Perimeter ntawm daim duab peb sab; thiab 'a', 'b', 'c' yog peb sab ntawm daim duab peb sab.
Vim li cas peb thiaj siv ib nrab ib puag ncig hauv cov qauv Herons?
Rationale for a convention: Vim li cas ho siv lub semiperimeter hauv Heron tus qauv? Heron tus qauv hais tias thaj tsam ntawm daim duab peb sab uas nws ob sab muaj qhov ntev a, b, c yog √s(s−a)(s−b)(s−c) qhov twg s=(a + b + c))/2 yog lub semiperimeter.
Dab tsi yog qhov ib puag ncig ntawm daim duab peb sab isosceles?
Perimeter ntawm Isosceles Daim duab peb sab: P=a + b + c=2a + b. Semiperimeter ntawm Isosceles daim duab peb sab: s=(a + b + c) / 2=a + (b / 2) Thaj tsam ntawm Isosceles daim duab peb sab: K=(b / 4)√(4a 2 - b2) Qhov siab a ntawm Isosceles Daim duab peb sab: ha=(b/2a)√(4a 2- b2)
Semi-perimeter yog dab tsi?
Nyob rau hauv geometry, lub semiperimeter ntawm ib tug polygon yog ib nrab ntawm nws perimeter. Txawm hais tias nws muaj xws li ib qho yooj yim derivation los ntawmlub perimeter, lub semiperimeter tshwm ntau txaus nyob rau hauv cov qauv rau daim duab peb sab thiab lwm cov duab uas nws muab ib tug cais lub npe.

Puas yog semi finalist?
suav tau. Ib tug semi-finalist yog ib tug player, kis las, lossis pab pawguas sib tw hauv semi-kawg. Semi-finalist txhais li cas? Lub ntsiab lus ntawm semi-finalist hauv lus Askiv ib tus neeg lossis pab pawg uas mus txog qhov semifinals (=ib qho ntawm ob qhov kev ua si uas tau ua si los txiav txim tias leej twg yuav koom nrog hauv qhov kev ua si zaum kawg los yog kev tshwm sim ntawm kev sib tw):
Vim li cas western blot semi quantitative?
Nws yog ib qho tseem ceeb heev uas yuav tsum paub tias cov ntaub ntawv tsim tawm nrog rau sab hnub poob blot feem ntau suav hais tias yog ib feem ntau. Qhov no yog vim nws muab kev sib piv ntawm cov protein ntau, tab sis tsis yog qhov ntsuas qhov muaj tseeb.
Lub tsev semi-detached txhais li cas?
Ib lub tsev semi-detached yog ib tsev neeg ob lub tsev nyob uas sib koom ib phab ntsa nrog lub tsev tom ntej. Lub npe txawv ntawm lub tsev no los ntawm cov tsev sib cais, tsis muaj phab ntsa sib koom, thiab cov tsev terraced, nrog cov phab ntsa sib koom ntawm ob sab.
Leej twg nrhiav tau semi kua?
Tom qab ntawd, xyoo 1846 Hugo von Mohl rov txhais lo lus (tseem hu ua Primordialschlauch, "primordial utricle") kom xa mus rau "tawv, slimy, granular, semi-kua. "cov khoom nyob rau hauv cov nroj tsuag hlwb, kom paub qhov txawv ntawm cov phab ntsa ntawm tes thiab cov cell sap (Zellsaft) nyob rau hauv lub vacuole.
Nyob rau hauv daim duab yog dab tsi yog qhov perimeter ntawm polygon?
Rau ib tug tsis tu ncua polygon, lub perimeter yog sib npaug rau cov khoom ntawm ib sab ntev thiab tus naj npawb ntawm sab ntawm lub polygon. Piv txwv li, lub perimeter ntawm ib txwm pentagon uas nws sab ntev 8 cm, yog muab los ntawm; luas=8 x 5=40 cm.
