5 dollar bill is the answer
Answer:
Step-by-step explanation:
In 
a is the initial value and b is the growth/decay rate. Our initial population was 25,000 so a = 25,000. Our rate of decay is 4% or, as a decimal, .04. BUT if the rate of decay is .04, then .96 remains. b = .96
Answer:
Equation is x^2/576+y^2/400=1
Vertical height is 19.84inches
Step-by-step explanation:
The equation of an ellipse with horizontal major axis with center at (0,0) is x^2/a^2+y^2/b^2=1
From the question, a=24 and b=20
Therefore the equation of the ellipse = x^2/24^2+y^2/20^2=1
= x^2/576+y^2/400=1
To calculate vertical height y:
y^2/400=1- x^2/576
y^2=(1- x^2/576)*400
y=20√(1- x^2/576)
At x=3 inches from the centre
y=20√1-0.0156
y=20*0.9922
y=19.84inches
Answer:
A
B
D
Step-by-step explanation:
A 230 divided by 4 is 57.5 which makes A a true statement.
B 296 divided by 5 is 59.2 which makes B a true statement .
D 296 - 230 =66
66 - 57.5 = 8.5
Which makes D a true statement by a margin of 8.5 words.
