Answer:
Step-by-step explanation:
<u>Given:</u>
- Initial population = 6.08 billion
- Increase rate = 1.5% or 0.015 times per year
Time passed = 2017 - 2000 = 17 years
<u>Population in 2017:</u>
- P = 6.08*(1 + 0.015)^17 = 7.8 billion
Answer:40.6cm

Answer:
Step 4
part a: no answer yet still having trouble showing my work
part b:
-0.125(x-24)^2+50
-0.125(x-24)(x-24)+50
-0.125(x^2-24x-24x+576)+50
-0.125(x^2-48x+576)+50
-0.125x^2+6x-75+50
-0.125x^2+6x-22
a=-0.125
b=6
c=-22
part c: yes he went through
part d:
plug in roots (4,0) and (44,0)
if x is 4 and y is 0
0=-0.125(4)^2+6(4)-22
0=-2+24-22
0=-2+2
0=0
if x=44 and y=0
0=-0.125(44)^2+6(44)-22
0=-242+264-22
0=-242+242
0=0
Answer:
x-int: (4, 0)
Step-by-step explanation:
First, we need to find the equation of the line.
The equation of a line is y = mx + b, where m is the slope and b is the y-intercept.
Thus, we need to find the slope first by using the slope formula:
or change in y / change in x
So we have: 
We must plug in the slope to find the y-intercept:
So the equation of the line is y = -x + 4
The x-intercept means that the y coordinate is 0 so we can use the equation:
