Step-by-step explanation:
I would assume the answer would be a. 18 assuming your trying to find the entire value of a triangle but have a missing value
Answer:
1. f(0) = 501170
2. decreasing
3. 2% decrease
4. 302438
Step-by-step explanation:
In 1995 x=0
f(x) = 501170(0.98)^0
f(0) = 501170
The population is decreasing since we are multiplying by .98 ^x
.98 is less than 1 so it is getting smaller each time.
1 -.98 = .02
It is decreasing by 2 % each year
2020-1995 =25 years
f(25) = 501170(0.98)^25
=302438.41862
Rounding to the nearest whole number
302438
3+4d-14=15-5d-4d
4d-11=15-9d
13d=26
d=2
2x^2 because you do (-4x^2)-x=(-6x^2) and solve for x to get 2x^2.
(4x+5)(4x-5)
= 16x^2 - 25
