If you take population data for each year for a number of years and find the average increase or decrease each year you can add or subtract that average from the latest year to get your answer
Answer:
-21
Step-by-step explanation:
Given:
h(x) = x − 1 - - - (1)
j(x) = −4x - - - - - (2)
h[j(5)]
j(5) = - 4(5) = - 20
g(-20) = - 20 - 1
Hence,
h[j(5)] = - 21
Answer:
exponential
Step-by-step explanation:
Answer:
45 boys
Step-by-step explanation:
55 + 45 = 100 so if 55% of the class is girls then the rest of the percentage of the class which is 45 should be boys
Answer: 800pi inches
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move
