Answer:
3. i think 15.5
4. 140*
Step-by-step explanation:
in number 4, d is a vertical angle to the angle measured at 140.
in number 3, QV=SV, so 17=4x-1 18=4x 18/4=x x=4.5
and TS=TQ, so 3(x) + 2 = 3(4.5) + 2 = 13.5 + 2 = 15.5 =TQ
2852.1 rounded to the nearest tenth of a mile is still 2852.1
Answer:
y=40
Step-by-step explanation:
The formula for Direct Variation is y=kx or k=y/x. In this case I would use k=y/x. If you're y is 8 and x is 3, this means that K=8/3. Using this, we know that X=15. We have to find a Y value so that the fraction with an x of 15 simplified is 8/3. To do this you would write 8/3 and y/15. Now cross multiply to get 3y=120. Divide by 3 to get y=40.

Answer:
The required constant of variation is 4 and the equation is y=4xz over w (over meaning a fraction)
I don't know if you need a explanation on how to do this, just let me know if so.

Answer:
![a(t) =n(0.25t^2)](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%280.25t%5E2%29)
Step-by-step explanation:
Given
Required
Determine the area in terms of time
From the question, we have:
-> radius per time
and
--> area from radius
The interpretation of the question is to find the composite function: a(t)
If
, and
, the
Substitute 0.5t for r
![a(t) =n(0.5t)^2](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%280.5t%29%5E2)
![a(t) =n*0.25t^2](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%2A0.25t%5E2)
![a(t) =n(0.25t^2)](https://tex.z-dn.net/?f=a%28t%29%20%3Dn%280.25t%5E2%29)
