Given tanx=8/15 when pi &lt; x &lt; 3pi/2, find tan x/2.
S_A_V [24]

Answer:

tan(x/2)=-4

Step-by-step explanation:

we know that

The angle x belong to the III quadrant -----> given problem

step 1

Find the angle x

x=arctan(8/15)=28.07\°

Remember that the angle x belong to the III Quadrant

so

x=28.07\°+180\°=208.07\°

step 2

Find angle x/2

x/2=208.07\°/2=104.035\°

step 3

Find tan(x/2)

tan(104.035\°)=-4

The weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper. Explain wether you think the relationship is
katrin [286]

I think the relationship between the weight of a stack of standard 8.5x11 copier paper vs number of sheets of paper is proportional because :

Let us assume here, in this situation that each page has the same weight so if i want to find the weight of the complete stack, i will multiply the number of sheets of paper by the weight of a single sheet of paper.

Factor 18x 6y using the greatest common factor
elena55 [62]
18x and 6y, though i can't see the operation between, can be factored by dividing out a 6. 6 is the greatest common factor, as it's a multiple of 18.

for 18x + 6y: 6(3x + y) is the factored form. if your symbol is subtraction, it's basically the same, you just change the sign.
