Answer:
684in^2
Step-by-step explanation:
Company A: y=6x+12
Company B: y=5x+15
x is the variable for how many windows they clean.
A:
y=6(8)+12
y=48+12
y=60
B:
y=5(8)+15
y=40+15
y=55
Company B charges less for 8 windows.
A:
y=6(6)+12
y=36+12
y=48
B:
y=5(6)+15
y=30+15
y=45
Company B charges $3 less than Company a to clean 6 windows.
ANSWER: 5 17/23 hrs (5.7391...)
How?
T = 11 hrs
K = 12 hrs
Together = X
1/11x + 1/12x = 1/x
11x/132 + 12x/132 = 132/132
11x x 12x = 23x —> 23x = 132 (divide 132 by 23x)
= 5.73913043 (5 17/23)
This quesion comes with 4 answer choices.
The right answer choice is the option "<span>A. A type of growth that is exponential at first but slows as the amount reaches a certain maximum value".
This question refers to the models of exponential and logistic growths to explain how populations grow. </span>
In exponential growth the rate of growth per capita keeps constant and the population graph is a "J" shaped curve, which grows unlimited.
In logistic growth the rate of growth per capita becomes smaller and smaller ant then the population reaches a maximum. The graph is an "S" - shaped curve.
