We have that
<span>3x-y-1=0-------------------> y=3x-1
using a graph tool
see the attached figure
the x-intercept is the point (0.333,0)
the y-intercept is the point (0,-1)
the slope is m=3</span>
Answer:
The population in 1995
501170
Is the population increasing or decreasing?
The population is decreasing
The rate of population change
population in the year 2020
302439
Step-by-step explanation:
Since 1995 is the base year, the population in 1995 is simply found by setting x equal to 0 in the given function;
The population is clearly decreasing over time since the base of the exponent, 0.98, is less than 1.
The rate of population change is obtained by differentiating the function with respect to x using the rule;
The population in the year 2020 is obtained by setting x equal to 25 in the population function since 2020-1995 = 25;
Answer:
L = 38, W = 92
or W = 38, L = 92
Step-by-step explanation:
Perimeter = 2 (Width + Length) = 260
→ W = 130 - L
Area = Width × Length = 3496
substitute W into area equation:
→
Using quadratic formula to find L:
Ill explain if this doesnt already make sense, hope it helps
