Answer: $2.90
Step-by-step explanation:
Each quarter is worth 25 cents so we do 8x25 which is 200 and we do 9x10 which is 90 and when we add them up we get 290 cents which is 2.90 dollars
(3 cos x-4 sin x)+(3sin x+4 cos x)=5
(3cos x+4cos x)+(-4sin x+3 sin x)=5
7 cos x-sin x=5
7cos x=5+sin x
(7 cos x)²=(5+sinx)²
49 cos²x=25+10 sinx+sin²x
49(1-sin²x)=25+10 sinx+sin²x
49-49sin²x=25+10sinx+sin²x
50 sin² x+10sinx-24=0
Sin x=[-10⁺₋√(100+4800)]/100=(-10⁺₋70)/100
We have two possible solutions:
sinx =(-10-70)/100=-0.8
x=sin⁻¹ (-0.8)=-53.13º (360º-53.13º=306.87)
sinx=(-10+70)/100=0.6
x=sin⁻¹ 0.6=36.87º
The solutions when 0≤x≤360º are: 36.87º and 306.87º.
K-mart is open from 8am to midnight on Monday to Saturday- there 16hrs from 8am to 12midnight
And on sunday it’s open from 10am to 8pm - so there is 10hrs from 10am till 8pm ....
So this is how you find your answer ...........✌️
*8am to 12midnight - 16hrs (Monday to Saturday)
*10am to 8pm - 10 hrs (Sunday)
*16hrs+10hrs=26
*26x7(days in a week )
*26x7=182
*therefore it’s opened for 182 hrs a week
....hrs means hours
