I need help on 4, 5, and 6.
Ahat [919]

Answers and Explanations:

4. They do not have a proportional relationship. For the first 3 sets, you can multiply x by 2.5 to get y. But that does not work for 8 and 18, so there is no proportional relationship between x and y.

5. Yes. For equilateral triangles, the side length is equal to the perimeter divided by 3, the number of sides. Vise versa, the side length times 3 equals the perimeter. If the side length is 3 in, multiply by 3 to get 9 in, the diameter.

6. Yes. it is proportional. X times 80 equals Y. In this case, in 8 hours, 640 tickets were sold.

Which postulate proves that the triangles below are similar?
Molodets [167]

Answer:

AA~

Step-by-step explanation:

These triangles are similar but not congruent. One triangle is bigger than the other, meaning none of the side lengths are the same. On the triangles, two angles are given, a 53 degree and a 90 meaning that you would us the AA rule to determine if they are similar. Which they are.

(secx)dy/dx=e^(y+sinx), please help me solve the differential equation. Thanks :)
nalin [4]
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

5(-3x-2)-(x-3)=-4(4x+5)+13

-15x-10-x+3=-16x-20+13

-16x-7=-16x-7

-16x=-16x

-x=-x

x=x

Factor 1/3 out of 1/3p-2/3 please answer this! Easy 20 points!
Tju [1.3M]

Answer:

\frac{1}{3} (\frac{1}{p} - 2)

Step-by-step explanation:

Given the equation = \frac{1}{3p} - \frac{2}{3}

Required: To factor out 1/3;

\frac{1}{3p} - \frac{2}{3}

1/3 is common to both sides;

So, 1/3 is a common factor

\frac{1}{3} (\frac{1}{p} - 2)

To solve for the value of p;

\frac{1}{3} (\frac{1}{p} - 2) = 0

\frac{1}{p} - 2 = 0

\frac{1}{p} = 2

1 = 2p

p = \frac{1}{2}
