Answer:
- Bradley has an exponential depreciation of 10.67 thousand per year.
- Spencer had an exponential increase of 14000 per year.
Step-by-step explanation:
At the beginning of 2000:
Bradley, B = 220000
Spencer, S = 114000
At the beginning of 2003:
Bradley, B = 188000
Spencer, S = 156000
Variation for the 3 years:
Bradley, B = 188000 - 220000
= -32000
Spencer, S = 156000 - 114000
= 42000
For 1 year:
Bradley, B = 32000 ÷ 3
≈ An exponential depreciation of 10.67 thousand per year
Spencer, S = 42000 ÷ 3
= An exponential increase of 14000 per year.
Answer:
a) k
= 3.6 N/m ; b) 9.43 * 10¹²; c) 1.18 * 10¹¹; d) 75.08 N/m
Step-by-step explanation:
Length of iron bar = L = 2.7m;
side length of cross section = a = 0.07cm = 0.0007m;
x = 2.7 cm = 0.027m;
m = 100kg;
ρ = 7.87gm/cm³;
da = 2.28 * 10⁻¹⁰m;
a)
Fnet = F - mg
where Fnet = 0
So,
F = mg where F=kx
k = mg/x = 100*9.8/0.027
k = 3.6 N/m
b)
Nchain = Aw/Aa =a²/(da)²
= (o.ooo7)²/(2.28 * 10⁻¹⁰)²
= 9.43 * 10¹²
c)
Nbond = L/da = 2.7/2.28 * 10⁻¹⁰
= 1.18 * 10¹¹
d)
Spring stiffness of wire = ksi = (Nbondk)/Nchain
= [(1.18* 10¹¹)(6*10⁴)]/(9.43 * 10¹²)
= 75.08 N/m
Answer:
53.85%
Step-by-step explanation:
there are 24 prime cards in a deck
52-24=28
28 is the number of non prime cards in a deck of cards
then you do 28/52=53.85%
H(x)=4 because if you make the x next to 4 is 3 so then you solve from there to get 4
