Answer:
D. 2019
Step-by-step explanation:
So I started by rewriting the function f(x)
1000 = 10^3 so
f(x)=10^3 times 1.03^x
1.03 = 103/100 so
f(x)= 10^3 times (103/100)^x
to raise a fraction to a power you just raise the numerator and denominator to that power so
f(x)= 10^3 times 103^x/100^x
change it to exponential form with a base of 10
f(x)=10^3 times 103^x/10^2x
then you can reduce it with the 10^3
f(x)=103^x/10^2x-3
so now that thats in more of a standard form you can find the intersection of the two functions
which is at (9.012,1305.244)
x is the number of years after 2010, so they will be equal ~9 years after 2010, which is 2019.
Answer:
$16
Step-by-step explanation:
Let $x be the amount of money Daniel spent.
Tracy spent $38 less than 3 times what Daniel spent.
Daniel spent = $x
3 times what Daniel spent = $3x
$38 less than 3 times what Daniel spent = $(3x-38)
So,
Tracy spent = $(3x-38)
If Tracy spent $10, then
Hence, Daniel spent $16
