Step-by-step explanation:

since x is in quadrant three,tan theta and cot theta are positive

<h2>__________________________</h2>

tan theta= opposite/adjacent

sin theta = opposite /hypotenuese

from triangle ,we know 2 sides hypotenuese and opposite as 5 and 3 respectively,we get third side as 4 using pythagorous theorem

tanx°=3/4

Two pencils and a ruler cost 98 cents in total. One pencil and 2 rulers cost $1.24 in total. Find the cost of each item.
salantis [7]

Answer:

2.16

Step-by-step explanation:

r = cost of ruler

p = cost of pencil

 

r = 2p

6r + 15p = 2.16

 

Substitute 2p in place of r in 2nd equation and solve for p

 

6(2p) + 15p = 2.16

12p + 15p = 2.16

27p = 2.16

What is the 45th term of the sequence generated by the formula (-1) 2n+1 ?
Natalija [7]

Answer:

−0.989010989010

Step-by-step explanation:

what is the 45th term of a sequence generated by the formula tn=(-1)^n * (2n/2n+1)?

When n= 45

tn=(-1)^n*(2n/2n+1)

tn = (-1)^45 * ( 2(45) / 2(45) + 1

= -1 * 90 / (90+1)

= -90 / 91

= −0.989010989010

The 45th term of the sequence generated by the formula tn=(-1)^n*(2n/2n+1) is −0.989010989010
