Mathematics
1 answer:
sertanlavr [38]3 years ago
8 0

Answer:

20

Step-by-step explanation:

because a line is 180° so pfc when you look, q=(2x-3)

so you must make an equation like this

(7x+3)+ (2x-3)=180

and solve it algebracially to get x=20

(secx)dy/dx=e^(y+sinx), please help me solve the differential equation. Thanks :)

First, you must know these formula  d(e^f(x) = f'(x)e^x dx, e^a+b=e^a.e^b, and d(sinx) = cosxdx, secx = 1/ cosx

(secx)dy/dx=e^(y+sinx), implies  <span>dy/dx=cosx .e^(y+sinx), and then 
</span>dy=cosx .e^(y+sinx).dx, integdy=integ(cosx .e^(y+sinx).dx, equivalent of 
integdy=integ(cosx .e^y.e^sinx)dx, integdy=e^y.integ.(cosx e^sinx)dx, but we know that   d(e^sinx) =cosx e^sinx dx,
so integ.d(e^sinx) =integ.cosx e^sinx dx,
and e^sinx + C=integ.cosx e^sinxdx
 finally, integdy=e^y.integ.(cosx e^sinx)dx=e^2. (e^sinx) +C
the answer is 
y = e^2. (e^sinx) +C, you can check this answer to calculate dy/dx

Leon usually does very well on tests, but he failed his most recent math exam. His teacher was very upset by Leon's performance
kondor19780726 [428]

Answer:

situational

Step-by-step explanation:

Based on the information provided within the question it seems that Leon's teacher made a situational attribution about his test performance. This term refers to when certain people believe that an individual's actions or behaviors are caused by a specific or various situational factors. Which is what his teacher is thinking by believing that his performance was affected by some problem or sickness (situational factors).

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Resolve into factors. p4+7p2q2+16q4​
uranmaximum [27]

Step-by-step explanation:

p⁴+8p²q²+16q⁴

(p²)²+2×p²×4q²+(4q²)²

We know that,

  • (a+b)²=a²+2ab+b²

Therefore,

  • (p²)²+2×p²×4q²+(4q²)²
  • (p²+4q²)²
  • (p²+4q²)(p²+4q²)
