Can you please help me?
garri49 [273]

Answer:

6.2

Step-by-step explanation:

\frac{10.3}{sin(90)} = \frac{x}{sin(37)}                 *Cross multiply*

10.3(sin(37)) = x(sin(90))   *Divide by sin(90) to isolate x*

x = \frac{10.3(sin(37))}{sin(90)}                  *Solve*

x = 6.19 ≈ 6.2

Answer:

1. add up all of the arcs.

2x+3x+4x-8+x-12

2. all of the arcs equal 360

2x+3x+4x-8+x-12=360

3. Find x

10x-20=360, x=38

4. angle LTE is equal to half of the sum of the intercepted arcs.

.5(arc LE +GF)

5. plug in LE +GF with x

.5(76+144)

LTE=110

Find the particular solution to y ' = 4sin(x) given the general solution is y = c - 4cos(x) and the initial condition y of pi ov
Lana71 [14]

The general solutions always have some additive/multiplicative constant, that you must fix in the particular solution.

In order to do so, you need to impose that the particular solution passes through a certain point. In your case, you have

y(x) = c-4\cos(x)

and you want

y\left(\dfrac{\pi}{2}\right) = 2

Put everything together, and you have

y\left(\dfrac{\pi}{2}\right) = c-4\cos\left(\dfrac{\pi}{2}\right) = c = 2

Since the cosine is zero in the chosen point. So, we've fixed the value of the constant, and the particular solution is found:

y(x) = 2-4\cos(x)

What is the area of 4 1/5 and 1 4/9 as a mixed number.
marusya05 [52]

Answer:

10 1/9

Step-by-step explanation:

To make it easier to answer, make both of them into an improper fraction

4 1/5 = 21/3

1 4/9 = 13/9

Now we can multiply them easier

21/3 x 13/9 = 273/27

27 goes into 273 10 times and the left over is 3 so the mixed fraction would be

10 3/27, to simplify

10 1/9
