Answer: See below
<u>Step-by-step explanation:</u>
y = a(b)ˣ
- y: final population of zombies
- a: initial population of zombies
- b: rate of decrease
- x: number of hours
Given: a = 500,000 b = 50% (0.5)
y = 500,000(0.5)ˣ
Since we want to know the number assassinated (A), subtract the total from the final population of zombies
A = 500,000 - y
a) Equation: 500,000 - 500,000(0.5)ˣ
b)
(Graph attached)
c) The assassins will earn 100,000 + 2(499,985) = $1,099,970 after 15 hours.
The number of zombies needed to assassinate in order to earn $1,000,000:
100,000 + 2z = 1,000,000
2z = 900,000
z = 450,000
d) How long will it take to eliminate all of the zombies?
The population of zombies is zero when x = 20 hours
How much money did the assassinators earn?
100,000 + 2(500,000) = $1,100,000
Answer:
84 cm³
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
__
The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...
A = 1/2bh
A = 1/2(8 cm)(7 cm) = 28 cm²
Then the volume of the triangular pyramid is ...
V = 1/3(28 cm²)(9 cm) = 84 cm³
Answer:
the correct answer is A
6/5x^10
Step-by-step explanation:
The exact
value of the given equation is 45 degrees or pi/4. I am hoping
that this answer has satisfied your query about and it will be able to help
you, and if you’d like, feel free to ask another question.
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
