As it is a straight line all the angles add up to 180 so 5s+18+48-a+8a-30= 180 so simplified 12a+36=180 then solve to get a=12.17 so then when u put 12.17 as a you get 5 * 12.17 +8 =78.85 then 48-12.17 which is clearly<78.85 then you do the final angle of 8*12.17-30 which is 67.36 so angle AOC is the biggest

(5a + 18) + (48 - a) + (8a - 30) = 180

5a + 18 + 48 - a + 8a - 30 = 180

5a - a + 8a + 18 + 48 - 30 = 180

12a + 36 = 180

12a = 180 - 36

12a = 144

a = 12

Which number should be added to both sides of the equation to complete the square x^2-10x=7
mixer [17]

Answer:

  25

Step-by-step explanation:

The number that needs to be added is the square of half the x-coefficient:

  (-10/2)^2 = 25

_____

Adding that gives ...

  (x -5)^2 = 32

  x = 5 ± 4√2

In a missile-testing program, one random variable of interest is the distance between the point at which the missile lands and t
Arisa [49]

Answer:

Step-by-step explanation:

From the given data

we observed that the missile testing program

Y1 and Y2 are variable, they are also independent

We are aware that

(Y_1)^2 and (Y_2)^2 have x^2 distribution with 1 degree of freedom

and V=(Y_1^2)+(Y_2)^2 has x^2 with 2 degree of freedom

F_v(v)=\frac{e^{-\frac{v}{2}}}2

Since we have to find the density formula

U=\sqrt{V}

We use method of transformation

h(V)=\sqrt{U}\\\\=U

There inverse function is h^-^1(U)=U^2

We derivate the fuction above with respect to u

\frac{d}{du} (h^-^1(u))=\frac{d}{du} (u^2)\\\\=2u^2^-^1\\\\=2u

Therefore,

F_v(u)=F_v(h-^1)(u)\frac{dh^-^1}{du} \\\\=\frac{e^-\frac{u^-^}{2} }{2} (2u)\\\\=e^-{\frac{u^2}{2} }U

Explain how you can approximate a cube root when the cube is not a perfect cube.
jenyasd209 [6]

Answer:

See below.

Step-by-step explanation:

It would take a long time to explain . There is a good method called Newton's method which involves graphs of the type

y = x^3 - n and applying calculus to produce cycles of approximation  until you'll get close to the required cubic root.

You'll find it on online videos.

Is the least number to be added to 5607 to get a perfect square. <br> pls add the steps.
daser333 [38]

Answer:

18

Step-by-step explanation:

70^2 = 4900 < 5607 < 6400 = 80^2

so sqrt(5607) is a two-digit number with tenth-digit 7

71^2 = 5041, 72^2 = 5184, 73^2 = 5329, 74^2 = 5476, 75^2 = 5625

so the smallest square bigger than 5607 is 75^2, which is 5625

so the number should ne 5625 - 5607 = 18

The work of a student to solve the equation 3(2x – 4) = 8 + 2x + 6 is shown below:
Blababa [14]
If you would like to know in which step did the student first make an error and what is the correct step, you can calculate this using the following steps:

3(2x - 4) = 8 + 2x + 6
6x - 12 = 8 + 2x + 6
6x - 12 = 14 + 2x ... Step 2
6x - 2x = 14 + 12
4x = 26
x = 26/4 = 13/2

The correct result would be Step 2; <span>6x - 12 = 14 + 2x.</span>
