Answer:
28
Step-by-step explanation:
Convert element to fraction:
2/3 x 42/1
Cross-cancel common factor:
2/1 x 14/1
Multiply Factors:
2 x 14
1 x 1
Multiply the numbers 14 x 2 = 28
And boom, the answer is 28!
Answer:

Step-by-step explanation:
we know that
In this problem we have a exponential function of the form

where
x ----> is the number of years since 2009
y ----> is the population of bears
a ----> is the initial value
b ---> is the base
step 1
Find the value of a
For x=0 (year 2009)
y=1,570 bears
substitute


so

step 2
Find the value of b
For x=1 (year 2010)
y=1,884 bears
substitute



The exponential function is equal to

step 3
How many bears will there be in 2018?
2018-2009=9 years
so
For x=9 years
substitute in the equation


2 x radius.
Description
In geometry, a diameter of a circle is any straight line segment that passes through the centre of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.
The best answer for the question of what illustrates the commutative property of addition is letter c which is 22 + 11 = 11 + 22. Because the commutative property of addition states that a + b = b + a, thus the chosen answer is the best answer.
