If tan (theta) =5/4 and cos (theta) &lt; 0 . Find the other trig. functions.
andrew-mc [135]
Tan(theta) = 5/4
sin(theta)/cos (theta)=5/4
cos(theta)=4sin(theta)/5
sin²(theta)+cos²(theta)=1
sin²(theta)+16sin²(iheta)/25=1  /*25
25 sin²(theta)+16 sin²(theta)=25
sin²(theta)=25/41    /√
sin(theta)=\frac{-5 \sqrt{41} }{41}
cos(theta)=\frac{-4 \sqrt{41} }{41}
cot(theta)=\frac{4}{5}
csc(theta)=1/sin(theta)=\frac{- \sqrt{41} }{5}
sec(theta)=1/cos(theta)=\frac{- \sqrt{41} }{4}

Harman [31]

Answer:

Donald needs 3 days to earn 3420 dollars

Step-by-step explanation:

Donald sells 760 marbles everyday. He sells each marble for 1.5 dollars

amount collected in one day= 760 \cdot 1.5=1140 dollars

In one day the amount earned is 1140 dollars

we need to find the number of days needs to earn 3420 dollars

Number of days needed is \frac{3420}{1140}=2.842

So its around 3 days

Donald needs 3 days to earn 3420 dollars

Juan will put fencing around the outside of the enclosure. How much fencing does he need for the enclosure?
adell [148]
If Juan intends to put fencing around the enclosure, that means that we are looking at the perimeter of the image (the outside). We can count the amount of lines between the dots to determine how much fencing he will need. After counting the perimeter of this figure, we see that the total is 22. We do not know what the units are, so for now we can just say that he will need 22 units of fencing to fully enclose this shape.
