Answer:
7
Step-by-step explanation:
I can get it into standard form of that certain conic section by completing the square
<span>
</span>
(x^2-2x)+(y^2-4y)-31=0
<span>
</span>
(x^2-2x+1-1)+(y^2-4y+4-4)-31=0
<span>
</span>
(x-1)^2-1+(y-2)^2-4-31=0
<span>
</span>
(x-1)^2+(y-2)^2-36=0
<span>
</span>
(x-1)^2+(y-2)^2=36
<span>
</span>
(x-1)^2+(y-2)^2=6^2
in form
(x-h)^2+(y-k)^2=r^2
r=radius
so how wide it is is the diameter which is 2 times of radius
6=radius
6 times 2=12
12 inches I assume if the units in equation is in inches
Answer: n=-5/3
Step-by-step explanation:
18n=-27-3
18n=-30
N=-30/18
N=-5/3
Hope this helps! :)
To solve for the problem, we list first all the given
Given:
Initial temperature, T1 = 100 degC
Final temperature, T2 = 19 degC
Time, t = 5 2/5 mins or 5.4 mins
Required: Change in temperature per minute
Solution:
Change in temperature per minute = (T1-T2)/t
Change in temperature per minute = (100 degC - 19 degC)/5.4 mins
Change in temperature per minute = 15 degC/min
<em>ANSWER: 15 degC per minute</em>
We want to determine x from the expression
b(5px - 3c) = a(qx - 4)
Expand each side.
5bpx - 3bc = aqx - 4a
Subtract aqx from each side.
5bpx - aqx - 3bc = - 4a
x(5bp - aq) - 3bc = - 4a
Add 3bc to each side.
x(5bp - aq) = 3bc - 4a
Divide each side by 5bp - aq
x = (3bc - 4a)/(5bp - aq)
