Step-by-step explanation:
first we want to convert it to minutes so we multiply 60m/s by 60. 3600m/min or 3.6km/min
we just multiply 50 by 3.6.
therefore the car travels 180km south west
The correct equation is P(t) = Po*e^(kt). Please enclose "kt" inside parentheses and use the " ^ " symbol to indicate exponentiation.
"k" is the growth constant, which here is 0.017. "t" is the number of yeasrs. P(7) is the population after 7 years. Po is the initial population, which in this case is 91 million.
The initial value, when t = 0, is 91 million.
After 7 years, the population, P(7), was P(7) = (91 million)*e^(0.017*7). This evaluates to P(7) = (91 million)*(1.070) = 96 million
Answer:
x=1
Step-by-step explanation:
when both are graphed the lines intersect at (1,0) or x=1
Answer:
$400
OR 
Step-by-step explanation:
$400 stays the same, 72 cents is 72/100. Simplify and voila
Area of the square = (9 m)^2 = 81 m^2
The four circular sectors combine to form a circle with diameter 9 m, hence radius 4.5 m.
Area of the circle = π (4.5 m)^2 = 20.25π m^2
Then the area of the shaded region is
81 m^2 - 20.25π m^2 ≈ 17.4 m^2
