There are actually 2 variations in this case.
> First case: the number of sides is an odd number
<span> The number
of lines of symmetry is simply equal to number of sides</span>
> Second case: the number of sides is an even number
<span> The
number of lines of symmetry is equal to twice the number of sides</span>
D because using the y=mx+b the slope(mx) is 1/2 (rise over run) and it starts at point 0,-2(b) since y is always 0 and -2 is the x value
Answer:
6
Step-by-step explanation:
The rate can be calculated as follows
x + x -16
2x-16
(2x-16)×5
10x - 80= 800
10x = 300-80
10x, = 220
x = 220/10
= 22
22-16
= 6 mph
Hence the rate of the west bound tsin is 6mph
Complete question:
The growth of a city is described by the population function p(t) = P0e^kt where P0 is the initial population of the city, t is the time in years, and k is a constant. If the population of the city atis 19,000 and the population of the city atis 23,000, which is the nearest approximation to the population of the city at
Answer:
27,800
Step-by-step explanation:
We need to obtain the initial population(P0) and constant value (k)
Population function : p(t) = P0e^kt
At t = 0, population = 19,000
19,000 = P0e^(k*0)
19,000 = P0 * e^0
19000 = P0 * 1
19000 = P0
Hence, initial population = 19,000
At t = 3; population = 23,000
23,000 = 19000e^(k*3)
23000 = 19000 * e^3k
e^3k = 23000/ 19000
e^3k = 1.2105263
Take the ln
3k = ln(1.2105263)
k = 0.1910552 / 3
k = 0.0636850
At t = 6
p(t) = P0e^kt
p(6) = 19000 * e^(0.0636850 * 6)
P(6) = 19000 * e^0.3821104
P(6) = 19000 * 1.4653739
P(6) = 27842.104
27,800 ( nearest whole number)
17 because 4 x 1.5 = 6, 50 / 1.5 = 33.33
