Akohia hoki Ngā Tauira Pātai mō te Pokapū o te Āhuatanga Taumaha
Te Mārama ki te Pokapū o te Āhuatanga Taumaha
E kiia ana he mea hanga te mea pakari i ngā matūriki maha nā tēnei te kaha ā-papa e pā ana ki ia o ēnei matūriki. Arā, he taumaha motuhake tō ia matūriki. Ko te pokapū taumaha o tētahi mea he pūwāhi kei runga, kei tata rānei ki te mea kei reira te taumaha o ngā wāhanga katoa o te mea e kukū ana.
Mena he ōrite te matotoru o ētahi mea (he rite te matotoru o ētahi mea, he rite rānei ngā rauemi o te mea), ā, he ōrite te āhua o te mea (hei tauira, he tapawhā, he tapawhā rite, he porowhita), ka ōrite te pokapū taumaha o te mea ki pokapū papatipu te mea kei waenganui o te mea. Mō te tapatoru, ko te pokapū o te papatipu kei te 1/3 h, ko h = te teitei o te tapatoru.
Tātai Pokapū o te Taumaha
Mena he ōrite te āhua o te mea, ā, he ōrite te mea, ka ōrite te pokapū o te taumaha ki te pokapū o te papatipu o te mea, kei reira pokapū o te taumaha ā, kei waenganui o te mea te pokapū o te papatipu. I tetahi atu taha, ki te rite te āhua o te mea engari kāore i te ōrite, ka taea te whakatau i te tūranga o te pokapū o te taumaha o te mea mā te whakamahi i te tātai e whai ake nei:
Ngā Mōhiohio:
x = waenganui o te mea i runga i te tuaka-x, y = waenganui o te mea i runga i te tuaka-y, A = horahanga o te mea.

1. Pātai Whakamātautau ā-Motu 2011/2012 C61 Nama 12
Tirohia te ahua o tētahi papa ōrite! Ko te taunga o te pokapū o te taumaha o te pūnaha ahanoa i te ahunga tuaka-y mai i te pūwāhi Q ko…
A. 1,00 henemita
B. 1,75 henemita
C. 2,00 henimita
D. 3,00 henimita
E. 3,25 henimita
Kōrero
Wehea te mea kia rua ngā wāhanga, te wāhanga 1 = tapawhā rite, te wāhanga 2 = tapatoru.
A1 = (12,5)(2) = 25
A2 = ½ (12,5-2,5)(3) = ½ (10)(3) = (5)(3) = 15
y1 = ½ (2) = 1
y2 = 1/3 (3) + 2 = 1 + 2 = 3
Ngā taunga o te pokapū o te taumaha o te mea i runga i te tuaka-y:
Pūwāhi Q = pūwāhi pango kei te pūtake o te pokapū o te mea.
Ko te whakautu tika ko B.
2. Pātai Whakamātautau ā-Motu 2011/2012 A81 Nama 12
Ko te tūnga o te pokapū o te taumaha o tētahi āhua papatahi e whakaaturia ana i te ahua i te taha mai i te tuaka-x ko...
A. 4,5 henemita
B. 4 henemita
C. 3,5 henimita
D. 3 henimita
E. 2 henimita
Kōrero
Wehea te mea kia rua ngā wāhanga, te wāhanga 1 = tapawhā rite, te wāhanga 2 = tapatoru.
A1 = (6-0)(3-0) = (6)(3) = 18
A2 = ½ (6-3)(6-3) = ½ (3)(3) = 4,5
y1 = ½ (3) = 1,5
y2 = 1/3 (6-3) + 3 = 1/3 (3) + 3 = 1 + 3 = 4
Ngā taunga o te pokapū o te taumaha o te mea i runga i te tuaka-y:
Ko te whakautu tika ko E.
3. Ngā Pātai Whakamātautau ā-Motu 2018
Kia tupato ki ngā kōrero e whai ake nei:
(1) Whakahokia te tukanga o te whakatau i te rārangi i runga i te kāri mai i ngā pūwāhi iri rerekē, ā, tohua te hononga o ngā rārangi e rua hei pokapū taumaha o te kāri.
(2) Herea ngā pito o te miro ki te ngira, ka tāpirihia te taumaha, ka werohia te ngira ki roto i te kāta.
(3) Tuhia he rārangi i te taha o ngā ira i runga i te kāri.
(4) Tohua ngā pūwāhi i te taha o te miro i runga i te kātene.
(5) whakairihia te kātene mā te pupuri i te turanga o te ngira
Hei whakatau i te taunga o te pokapū taumaha o tētahi pepa kātene koretake, ko te raupapa tika o ngā mahi ko...
Kōrero
Ko te raupapa tika o ngā mahi ko 2, 5, 4, 3, 1.
