Answer:cos( A + B ) = cosAcosB - sinAsinB ;
cos( A + B ) / ( cosAsinB ) = ( cosAcosB - sinAsinB ) / ( cosAsinB ) = ( cosAcosB ) / ( cosAsinB ) - ( sinAsinB ) / ( cosAsinB ) = cosB / sinB - sinA / cosA = cotB - tanA ;
tan²(x) - sin²(x) = sin²(x)/cos²(x) - sin²(x)
… = sin²(x) (1/cos²(x) - 1)
… = sin²(x) (sec²(x) - 1)
… = sin²(x) tan²(x)

Answer:
100x+120y = z
z= $ 63000
Step-by-step explanation:
Product Welding Assembly Painting Cont. to profit
X 2x hours 3x hours 1xhour = $100x
Y 3y hours 2y hours 1y hour = $120y
<u> </u>
Total hours 1500 hours 1500 hours 550 hours
available
Let X represent product X
Let Y represent Product Y
2x + 3y = 1500
x + y = 550
y= 550-x
2x + 3(550-x) = 1500
2x + 1650- 3x = 1500
150 = x
y = 550-150
y = 400
Objective Function Z = 100x + 120y
Z = 100(150) + 120( 400)
Z = 15000+48000
Z = $63000
Ok so you have to work backwards so lets say
x=50
work backwards does the answer you got make sense for it to be that answer
I’m not sure...but I think
x+y=5
If x =15
Then 15+y=5
Y= 10

Answer: It's in the step-by step explanation
Step-by-step explanation:
I just learned about this too. I'll use what I know to help you out.
According to whatever law of the circle, where you have two intersecting lines within the bounds of a circle(that'd be TQ and SW), the product of the divided segments will equal each other.
So to put that in terms, TU times QU = SU times WU.
So let's get the value of segment TU, which is 1.5
Then let's get the value of segment of QU, which is 4.
Now let's get the value of WU, which is 3. We don't know what SU is yet. So put it in algebraic form.
1.5(4)=3x
6=3x
2=x
