Step-by-step explanation:

...Im not rlly that useful rn, sorry...!

I have a TI-84 graphing calculator that has a polynomial app solver on it, and i often use that since im not in algebra anymore. (i forgot how to do decomposition)--->

I do know you must use decomposition for this, or you can use the quadratic formula to substitute.

AD= 36 cm. Points C, B∈AD, such that AB:BC:CD=2:3:4. Find the distance of midpoints of the segments AB and CD.

Sav [38]

Answer:

The distance of the midpoint of AB = 4 cm

The distance of the midpoint of CD = 28 cm

Step-by-step explanation:

The given information are;

Segment AD = 36

Point C and point B are points on AD such that AB:BC:CD = 2:3:4

Which gives;

The proportion of AB in AD = 2/(2+3+4) = 2/9

The length of AB = 2/9×36 = 8 cm

The proportion of BC in AD = 3/(2+3+4) = 3/9

The length of AD = 3/9×36 = 12 cm

The proportion of CD in AD = 3/(2+3+4) = 4/9

The length of AD = 4/9×36 = 16 cm

The coordinate of the midpoint of AB = 8/2 = 4 cm from A

The distance of the midpoint of AB = 4 cm

The coordinate of the midpoint of CD = 8 + 12 + 16/2 = 28 cm from A

The distance of the midpoint of CD = 28 cm.

Does anyone know what the simplest form is? Will give brainiest

Ahat [919]

Hello from MrBillDoesMath!

Answer:

Choice B.

Discussion:

From the first step

324 x^6 y^ 8 =

2^2 * 3^4 * x^2 * x^4* y^8

so the fourth root of this is

2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =

2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =

(2x)^(1/2) * 3 * x * y^2 =

3 * x * y^2 * sqrt(2x) =

3 * x * y^2 * ( (2x)^2) ^ (1/4)) =

3 * x * y^2 * (4x^2) ^ (1/4)

which is choice B

Thank you,

MrB
