Answer:the answer is $78.09
Step-by-step explanation:
Let’s make two equations. D being dimes and Q being quarters.
D+Q=100
0.1d+0.25q=14.05
Now, let’s multiply the first equation by -0.10 so that we can cancel out D.
-0.1D-0.1Q=-10
0.1d+0.25q=14.05
Let’s solve
0.15Q=4.05
Let’s divide.
Q=27
So there’s 27 Quarters. Since there are 100 in total, there must be 73 dimes.
Let’s make sure this adds up.
0.25(27)+0.1(73)
6.75+7.30
14.05
So there’s 27 Quarters.
Answer:
started off from maximum, so f(x) = acos(bx)
max(f(x))=a=4
f(x)=4cos(bx)
the period is T = 2π
b=2π/T=2π/2π
b=1
f(x)=4cos(x)
36+10=46 the answer you are looking for is 46.
