Step-by-step explanation:

Basically they are saying that after you ADDED on 4 people it became 28. So in order to get 28 you had to add on 4 to the original number of people. Therefore it is n + 24 = 28

How does one go about completing this?

natali 33 [55]

Answer:

100°

Step-by-step explanation:

∠AEC ≅ ∠BED as vertically opposite angles

m∠AEC = m∠BED = 1/2(mAC + mBD), angles between intersecting chords

Substitute values and solve for x:

4x = 1/2(120 + 2x)
4x = 60 + x
3x = 60
x = 20

Find the measure of AEC:

m∠AEC = 4*20 = 80°

AED and AEC form a linear pair hence supplementary:

m∠AED = 180° - m∠AEC

Find the measure of ∠AED:

m∠AED = 180° - 80° = 100°

How do you do question b?

notsponge [240]

Part (b)

We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

$\arcsin(4y) = x^2 + C\\\\\arcsin(4*0) = (0)^2 + C\\\\\arcsin(0) = C\\\\0 = C\\\\C = 0\\\\$

-----------------

This means,

$\arcsin(4y) = x^2 + C\\\\\arcsin(4y) = x^2 + 0\\\\\arcsin(4y) = x^2\\\\4y = \sin(x^2)\\\\y = \frac{1}{4}\sin(x^2)\\\\$

is the solution with the initial condition y(0) = 0.

How many time does 2 go into 19

BigorU [14]

Hello There @Diamondinthesky123 (Cute Username)

When you state the question, "How many times does 2 go into 19", I assume your talking about Long Division. (Not so long in this case)

In this case, we would divide 19 by 2, resulting in 9 with a remainder of 1.
Thats It! :)

I hope I helped, Have a great Day!

Thank you,
Darian D.
