Answer:
m∠QRS = 52°
Step-by-step explanation:
From the given figure,
In right triangles ΔRQT and ΔRST,
QT = TS = 7.5 units [Given]
RT ≅ RT [Reflexive property]
ΔRQT ≅ ΔRST [By HL theorem of congruence]
Therefore, m(∠QRT) = m(∠SRT) = 26° [CPCTC]
m(∠QRS) = 2m(∠QRT)
= 2×(26°)
= 52°
Answer:
Step-by-step explanation:
Tear this apart piece by piece
15 - 8 = 7
7 * 3 = 21
11 + 21 = 32
Now so far this much is correct. The problem is the next sign. Is it add or is it divide. The only way to resolve it is to do it both ways.
Add 4
32 + 4 = 36
Divide 4
32 / 4 = 8 1/4 = 8
Answer:
P1= -2/3
P2= -10/3
Step-by-step explanation:
take the sq rt of both sides and use both + and - roots
3P+6=4
3P+6=-4
subtract 6 from both sides for each one
3P=-2
P=-2/3
3P=-10
P= -10/3
Use these equations when converting polar equations to parametric equations:
![x=r\cos\theta](https://tex.z-dn.net/?f=x%3Dr%5Ccos%5Ctheta)
![y=r\sin\theta](https://tex.z-dn.net/?f=y%3Dr%5Csin%5Ctheta)
We know that
, so substitute that into both equations for x and y.
![x=5\theta\cos\theta](https://tex.z-dn.net/?f=x%3D5%5Ctheta%5Ccos%5Ctheta)
![y=5\theta\sin\theta](https://tex.z-dn.net/?f=y%3D5%5Ctheta%5Csin%5Ctheta)
Now, replace
with any variable that you want to represent the parametric equations in. I'll use the standard variable, ![t](https://tex.z-dn.net/?f=t)
![x=5t\cos t](https://tex.z-dn.net/?f=x%3D5t%5Ccos%20t)
![y=5t\sin t](https://tex.z-dn.net/?f=y%3D5t%5Csin%20t)
Thus,
represented in parametric form is:
![(x,y)=(5t\cos t, 5t \sin t)](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%285t%5Ccos%20t%2C%205t%20%5Csin%20t%29)
Let me know if you need any clarifications, thanks!

The 16 oz bottle costs less. One cent less, to be exact. I came up with this by dividing the total cost (2.40) by the size of the bottle (16). I came up with .15. I did the same with the other cost and size, coming up with .16.
