B=1260.
(according to your question on #11, stating a regular polygon with interior angles adding up to 1260)
Answer:
82.49 percent were at least high school graduates.
Step-by-step explanation:
We have been given that at 1950 x=0
and at 1960 x=10
And following this pattern at 2000 x=50
So, we have coordinates:
(0,34.7) and (50,87.8) for two point form we will find a function:
Using:
Substituting the values in the formula we get:
y=1.062 x+34.7 is the linear function
(b) Now, we need to find the value at x= 1995 which will be equal to 45 according to the pattern followed
Put x=1995 in the function above we get:
y =1.062(45)+34.7
y=82.49 percent were at least high school graduates.
The compound interest formula is:
F = P * (1+i) ^ (n*t)
where:
F = future value
P = present value
i = r/n ; r = interest rate, n = number of times interest is compounded per year
t = number of years
Substituting:
F = 800 * ( 1 + .032/1 ) ^ (1*15) ; n=1 since compounded annually
F = 800 * ( 1 + 0.032) ^ (15)
F = 800 * ( 1.032) ^ 15
F = 800 * ( 1.60396711263693 )
F = 1283.17369010954
So there will be $1283.174 in the account.
Answer:
D.
Step-by-step explanation:
The x-axis of the graph isn't constant with the years. It cannot be consistent if the first twenty years are scaled together and the last 10 are put in increments of 2 years.
