7000 + 224.16 = $7,224.16
This would the balance in her account.
I’d say the second one, the fourth one and the fifth one.
Hope it works :)

Answer:
Step-by-step explanation:
You can start by recognizing 19/12π = π +7/12π, so the desired sine is ...
sin(19/12π) = -sin(7/12π) = -(sin(3/12π +4/12π)) = -sin(π/4 +π/3)
-sin(π/4 +π/3) = -sin(π/4)cos(π/3) -cos(π/4)sin(π/3)
Of course, you know that ...
sin(π/4) = cos(π/4) = (√2)/2
cos(π/3) = 1/2
sin(π/3) = (√3)/2
So, the desired value is ...
sin(19π/12) = -(√2)/2×1/2 -(√2)/2×(√3/2) = -(√2)/4×(1 +√3)
Comparing this form to the desired answer form, we see ...
A = 2
B = 3
Step-by-step explanation:
Use the sine and cosine trig functions
21) cos(52)=13/x
x=13/cos(52)
x=21.1
22) sin(75)=6/x
x=6/sin(75)
x=6.2
