Step-by-step explanation:
Adding/subtracting fractions requires equal denominators
4/10+40/100
(4/10)(4/4)+40/100
16/100+40/100
(16+40)/100
56/100 divide numerator and denominator by 4 to simplify the fraction
14/25
Answer:
Step-by-step explanation:
The end behavior of this function is the same as that of y = -x^2: the graph starts in Quadrant III and continues in Quadrant IV; the shape is roughly that of an upside-down parabola.
Answer:
annual growth rate m = 637.5 people / year
Step-by-step explanation:
Solution:-
- The scatter plot displaying the city's population was modeled by a linear equation of the form:
y = m*x + c
Where, m and c are constants.
- The scatter plot displayed the following relation of the city's population (p):
p = 637.5*t + 198,368.1
Where, p : The population in t years after after 1990
t : The number of years passed since 1990.
- The slope of the graph "m = 637.5" denotes the rate of change of dependent variable with respect ot independent variable:
dp / dt = m = 637.5
- So the rate of change of population per unit time t since 1990 has been constant with a an annual growth rate m = 637.5 people / year
