(-15x-3)+(7x-6)+(-2x+9)=-15x-3+7x-6+(-2x)+9=-15x-3+7x-6-2x+9=-10x
Answer:
Jayden's solution is incorrect.
Jayden divided 14 by 2 and then added 1.5
Jayden substituted the wrong value for a.
Answer: $2112.40
Step-by-step explanation:
r = 0.02 (2%)
n = 365 (daily for a year)
p = 1950
You wrote the formula wrong too:
B = P x (1+r/n)^nt
t = 4
B = 1950 x 1.08...
B = $2112.40
A bearing of 34° corresponds to corresponding angle of θ=90-34=56°
The (x,y) values for the position of the ship after completing its first heading are:
x=(10.4cos 56)
y=(10.4sin56)
The trigonometric angle for θ=90-90=0
The (x,y) values for the postion of the ship after completing the second bearing is:
x=(10.4 cos56)+(4.6cos0)≈10.4 mi
y=(10.4sin56)+(4.6sin0)≈8.6mi
the distance from the port will therefore be:
d=√(10.4²+8.6²)≈13.5 miles
It trigonometric angles is:
θ=arctan(y/x)
θ=arctan(8.6/10.4)
θ≈39.6°
Thus the bearing angle is:
90-39.6=50.4°
Answer:
If Andrew works for 30 for $4 he will have a total wage of 30×4=$120
And gets additional $5for every hr worked beyond 30hrs in that week
So he gets a total of 5(x-30)
So if he works for 40hrs he gets a total wage of
5(40-30)=50
120+50=$170
If he works for 50 hours he gets Total wage of
5(50-30)=100
120+100=$220
