Answer:
Permutation is used.
No. of arrangements = 1260
Step-by-step explanation:
Permutation is used for choosing & arrangement of 'r' out of 'n' objects, when sequence is important.
Total no. of alphabets in CORRECT = 7
C is repeated twice, R is repeated twice
So, Total No. of arrangements = <u>7 !</u>
(2!)(2!)
= 5040 / 4
= 1260
To make it easier just assume there is no decimal point then just work out the 32÷4 where we know that 4 goes into 32 8 times so you get 8 remember the decimal point and since it was one decimal place you will push the decimal over to the left of 8 and that is how you get 0.8
First. y=2x
second d is correct
third is a

Step-by-step explanation:
Answer:
Tacoma's population in 2014 will be 587,439 people
Step-by-step explanation:
we know that
The equation of a exponential growth function is given by the formula

where
y is Tacoma's population in thousand
x is the number of years since 2000
r is the rate of change
a is the initial value
we have

substitute


what will Tacoma's population be in 2014?
Find the value of x

substitute the value of x

therefore
Tacoma's population in 2014 will be 587,439 people
