Hope I helped and have a great day!
P.S. brainliest would really help im one away from virtuoso
<u>3x + 2y = 4</u>
Here are a few different ways
to represent the same line:
2y = 4 - 3x
y = -1.5x + 2
5y = -7.5x + 10
3x = 4 - 2y
x = -2/3y + 4/3
11 and 12 that’s the answer
Answer:
69.92°F
Step-by-step explanation:
Given:
Initial temperature ( i.e at time, t = 0) = 40°F
Temperature of the room = 70°F
Temperature after 10 minutes ( i.e at time t = 10 ) = 48°F
Now, from Newton's law of cooling
T'(t) = k(A - T(t))
T(t) temperature after time t
T'(t) =
here, A is the room temperature
thus,
= k(70 - T)
or
= kdt
on solving the differential equation, we get
T =
............(1)
Now from the boundary conditions,
i.e at time, t = 0; T = 40°F
we get,
40 = 
or
C = 30
and,
at time, t = 10; T = 48°F
thus,
48 = 
or
k =
or
k = 0.03
Therefore,
for t = 25
from 1 we have
T = 
or
T = 70 - 0.0780
or
T = 69.92°F
For the answer to the question above, the answer is 16.
You would divide 12 by 3 since that's the number of red dots per blue. Then multiply by four and there's the answer!
I hope my answer helped you. Feel free to ask more questions. Have a nice day!
