Answer:
631139.04 kilometers in 3 years
Step-by-step explanation:
Let x = how many kilometers she walk
y = time (minutes)
Since she walks 4km in 10 minutes.
x = 4, y = 10
(4,10)
But how many minutes if she walk only a kilometer? Divide x and y by 4.
(1,2.5)
She walks a kilometer under 2.5 minutes.
Now finding rate of changes.
Since m = 2.5
and of course, the function should be proportional so the equation should be y = mx.
Since time should be minutes instead of years.
Since 3 years = 1577847.6 minutes
Divide both sides by 2.5
Answer:
A) True
Step-by-step explanation:
The ordered pair for the first expression is ...
y = f(x)
-3 = f(1)
(x, y) = (1, -3)
The ordered pair for the second expression is ...
y = f^-1(x)
1 = f^-1(-3)
(x, y) = (-3, 1)
The second ordered pair is the reverse of the first, so represents a point described by the inverse function. The statement is True.
Relative frequency = event/sample space
50/14 = 0.28
Expected probability = relative frequency*event
0.28*7500 = 2100
About 2100 trout is expected to be in the lake.
Answer:
2720 feet
Step-by-step explanation:
u can draw a right triangle whose opposite side is 1700 feet, the adjacent side is the ground distance from Charlie to the plane (x), and the angle between theses sides is 32°.
Then, tan (32°) = 1700 feet / x => x = 1700 feet / tan(32°) = 1700 feet / 0.625 = 2720 feet.
Answer:
Step-by-step explanation:
Given that,
Central angle, 
Diameter,d = 5.8 m
Radius, r = 2.9 m
We need to find the area of sector. The formula for the area of sector is given by :
So, the area of a sector is equal to 
.
