Answer:
1120 Eagles
Step-by-step explanation:
If the population of Eagles decreases by 4% percent each year, then in 2030 (which is 15 years later), the population would decrease by (4 × 15)%
that is 60%
This indicates that the population of bald eagles in the year 2030 would be 60% less of what it was in the year 2015.
so we have, 
× 2800
which gives us 1680
this means that the number of bald eagles in the year 2030 would be 1680 less than the number of bald eagles in the year 2015
hence 2800 - 1680
then the answer is 1120 Bald Eagles
1/3 1/3 1/6= 1+1=2/6 1/6=3/6 simply it to 1/2
Answer:
The one that gives us the fastest y-intercept is "b". The coordinates are (0,15).
Step-by-step explanation:
In order to check which form gives us the fastest y-intercept value, let's apply x = 0 in all three of them and check how many operations we need to do to get our desired results.
a) f(x) = -3*(x - 2)² + 27
f(0) = -3*(0 - 2)² + 27
f(0) = -3*(4) + 27
f(0) = -12 + 27
f(0) = 15
b) f(x) = -3*x² + 12*x + 15
f(0) = -3*(0)² + 12*(0) + 15
f(0) = 15
c) f(x) = -3*(x + 1)*(x - 5)
f(0) = -3*(0+1)*(0-5)
f(0) = -3*(-5)
f(0) = 15
The fastest one is "b". Since it is in the standard second degree equation form "a*x² + b*x + c", we could have checked immediately by the value of "c".
The y-interecept is (0,15).
The discount price is $24 (20% of 30 is 6 ; 30-6=24)
