Answer:
a) v=6
b) s= u^2 - v^2 : -2a
Step-by-step explanation:
v^2=u^2+2as
u=12, a=-6, s=9
a)
(12)^2= 12 * 12= 144
v^2=u^2+2as
v^2=(12)^2+ 2*(-6)*9
v^2=144+(-12)*9
v^2=144+(-108)
v^2=36
v=6
b)
v^2=u^2+2as
-2as=u^2 - v^2
s= u^2 - v^2 : -2a
check for s
s= 144 - 36 : -2(-6)
s= 108 : 12
s=9 (equal vs the given)
Answer:
Few animal combinations of 3 animals given income & prices :- Only one of cow, horse, or ship bought ; less than 100 , 200 , 200 respectively.
Step-by-step explanation:
Budget Set is the combination of goods, which can be afforded by a consumer, given money income & prices.
Given : Budget Income = 100
Cow Price (C) = 1 ; Sheep Cost (S) = 0.5 ; Horse Cost (H) = 0.5
Maximum number of either cow, or sheep, or horse only that Farmer can buy with given prices & budget income (not buying the other ones):-
- C = 100 / 1 = 100
- S = 100 / 0.5 = 200
- H = 100 / 0.5 = 200
So, some animal combination, that farmer can buy with available income budget & given prices :-
- ( C , 0 , 0 ) ; where C < 100
- ( 0 , S , 0 ) ; where S < 200
- ( 0 , 0, H ) ; where H < 200
Answer:
just take the whole number (1) times the denominator (18) plus the numerator (7)
therefore: 1*18 = 18
18+7 = 25/18
t/120 ft = 2 ft/(4/3)ft
-----
t = 120[6/4] = 180 ft (tower's height)
Answer:
<1 : 36 degrees
<2 : 90 degrees
<3 : 36 degrees
<4 : 54 degrees
Step-by-step explanation:
First off, rhombus's have right angles formed at the middle, meaning that <2 is 90 degrees. Then, it's given that angle is 54 degrees, and its alternate interior angle is the one that is adjacent to <3. To find <1, add 90 and 54, and subtract that from 180. So <1 is 36 degrees. So that automatically makes < 3, 36 degrees and < 4, 54 degrees.
