Answer: 7(sin 50 degrees)
Step-by-step explanation:
Answer is 145.6cents. If 1 copy is 14.56cents, it implies 10 copies = 10(14.56)
Answer:
2.2%
Step-by-step explanation:
Given the following :
Population in year 2000 (A) = 4.2 million
Expected population every 32 years = 2 *A
The growth rate per year =?
The population figure after 32 years = (2 * 4.2 million) = 8.4 million
Using the exponential growth formula :
P(t) = A × (1 + r)^t
(1 + r) = g = Total growth percent
A = Initial population
t = time
P(t) = 8.4 million
8,400,000 = 4,200,000 × g^32
g^32 = (8400000/4200000)
g^32 = 2
Taking the root of 32 on both sides
g = 1.02189714865
g = (1 + r)
1.02189714865 = 1 + r
r = 1.02189714865 - 1
r = 0.02189714865
.rate = 0.02189714865 * 100
= 2.18971486541%
= 2.2% ( nearest tenth)
It would take Alexandria 8 months to earn the money.
125-20= 105 monthly earnings after personal expenses
800/105= 7.6 which rounds to 8.
8x105= 840
Answer:
11x + 20
Step-by-step explanation:
x2 + 9x + 20
2x + 9x + 20
11x + 20
Hope this helps!
