Answer:
The first account earns an interest of $511.11
Step-by-step explanation:
a). Interest in the first account
The total amount of interest earned in 10 years can be expressed as;
Compound interest=(P(1+r/n)^nt)-P
Where;
P=Principal amount
r=Interest rate
n=number of times the interest is compounded annually
t=number of years the account is kept
In our case;
P=$900
r=4.6/100=0.046
n=1
t=10 years
Replacing;
Compound interest=900(1+0.046/1)^(1×10)-(900)
Compound interest=900(1.046)^10-(900)
Compound interest=1,411.105-900
Compound interest=$511.105
Nearest cent=1/100=0.01 two decimal places
511.105=511.11
The first account earns an interest of $511.11
Sin(pi/4) = 1/sqrt(2)
csc(pi/4) = sqrt(2)
csc^2(pi/4) = 2
-csc^2(pi/4) = -2
With the true and the right negative
If graph of the function y=f(x) was shifted to the right 1 unit, then you got new function y=f(x-1).
Reversly, if you have the function
that is obtained by shifting to the right 1 unit, then the initial function was
.
Answer: Correct choice is D.
