Answer:
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute
Step-by-step explanation:
When x=0 (no minutes have elapsed), the value of the function is ...
f(0) = 75(2^0) = 75(1) = 75 . . . . the initial number of cells
As x increases by 1 (minute), the number of cells is multiplied by 2, so the 2 is the multiplier each minute. It indicates the number doubles. ("double" = "multiply by 2")
x is not defined, but for the function to make any sense, it must represent elapsed minutes.
Answer:
Interest Rate on 2-Year Loan...$435.6
Interest Rate on 5-Year Loan...$1,452
Step-by-step explanation:
The formula for calculating simple interest is as follows.
I = P x R x T,
where I = interest
P= Principal
R= interest rate
T= time
For the loan at 4.5 percent for 2 years, the interest will be
= $4,840 x 4.5/100 x 2
= $4,840 x 0.045 x 2
= $435.6
Total cost of the loan will principal plus interest
=$435.6 + $4,840
=$5,275.6
Monthly loan cost
= $5,275.6/24
=$219.81
Total loan cost..$5,275.6
Monthly loan cost ...$219.81
For the Loan at 6 percent for 5 years, the interest will be
= $4,840 x 6/100 x 5
= $4,840 x 0.06 x 5
=$1,452
Total cost of the loan will be principal plus interest
=$ 4,840 + $1,45
=$6,292
Monthly costs will be
=$6,292/60
=$104.87
Total loan cost... $6,292
Monthly loan costs... $104.87
Answer:
16 2/3 %
Step-by-step explanation:
Since the price went down, we are find the percent decrease.
Percent decrease = (original price - new price)/ original price
= (90 - 75)/90
=15/90
.1666666666666
Changing to percent form
16.6666666666666666666666%
16 2/3 %
Answer is A. -2x + 3z
Reason
2x + y = 3z
If you subtract 2x from both sides to isolate “y”
2x -2x +y = -2x + 3z
Now combine like terms
You get
y= -2x + 3z
Problem solved
Answer:
Option b. degrees Fahrenheit/(mililiters)
Step-by-step explanation:
we know that
The formula to calculate the average rate of change between two points is equal to
we have that
the units of the y-axis are 
the units of the x-axis are 
therefore
the units of the the average rate of change are
