Yes, it this somehow related to mathematics? Was this a question?
Step-by-step explanation:
11b)
(0;14), (1;10), (2;6), (3;2)
12a)
350-65=285
285÷19=15
m=15
(15;350)
Answer:
1)
2)
So then the model would be given by:
Step-by-step explanation:
For this case we have the following differential equation:
We can do this using algebra:
Part 1
And now we can integrate both sides like this:
We can use the u substituton for the left part
We can multiply both sides by 4 and we got:
, where
and after integrate the left part we got:
And if we apply exponential on both sides we got:
Now we can replace u and we got:
where
And then finally we have:
Part 2
For this case we have the initial condition y(0) =5 and if we use it we got:
So then the model would be given by:
Every triangle’s inner angles’ addition equals to 180°
So if we find the x:
38°+x+2°+x=180°
40°+2x=180°
2x=180°-40°=140°
x=140°/2
x=70°
Now if we find the I hope this helped :)
Answer:
x=5/2
Step-by-step explanation:
1. 13=6x-2 (add 2 to each side)
2.15=6x (divide each side by 6)
3.15/6=x (simplify the fraction by dividing by 3)
4.5/2=x (answer)
