What are the real zeroes of x3 + 6 x2 – 9x - 54?
o-na [289]

Answer:

Option B 3,-3,-6 is correct.

Step-by-step explanation:

We need to find real zeroes of x^3+6x^2-9x-54

Solving

x^3+6x^2-9x-54\\=(x^3+6x^2)+(-9x-54)

Taking x^2 common from first 2 terms and -9 from last two terms we get

=(x^3+6x^2)+(-9x-54)\\=x^2(x+6)-9(x+6)\\

Taking (x+6) common

(x+6)(x^2-9)\\

x^2-9 can be solved using formula a^2-b^2 = (a+b)(a-b)

=(x+6)((x)^2-(3)^2)\\=(x+6)(x+3)(x-3)

Putting it equal to zero,

(x+6)(x+3)(x-3) =0\\x+6 =0, x+3=0\,\, and\,\, x-3=0\\x=-6, x=-3\,\, and\,\,  x=3

So, Option B 3,-3,-6 is correct.

Three collinear points on the coordinate plane are r(x,y), s(x+8h, y+8k), and p (x+6h, y+6k)
Karo-lina-s [1.5K]

Answer:

A.\frac{RP}{SP}=3

B.\frac{RP}{RS}=\frac{3}{4}

Step-by-step explanation:

<u><em>The complete question is</em></u>

Three collinear points on the coordinate plane are R(x, y), S(x+8h, y+8k), and P(x+6h, y+6k).

<em>Part A: Determine the value of RP/SP</em>

<em>Part B: Determine the value of RP/RS</em>

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

R(x,y),S(x+8h,y+8k) and P(x+6h,y+6k)

Part A.We have to find the value of \frac{RP}{SP}

step 1

Find the distance RP

R(x,y),P(x+6h,y+6k)

substitute the values in the formula

RP=\sqrt{(x+6h-x)^2+(y+6k-y)^2}

RP=\sqrt{36h^2+36 k^2}

RP=6\sqrt{h^2+k^2}

step 2

Find the distance SP

S(x+8h,y+8k),P(x+6h,y+6k)

substitute the values in the formula

SP=\sqrt{(x+6h-x-8h)^2+(y+6k-y-8k)^2}

SP=\sqrt{4h^2+4k^2}

SP=\sqrt{4(h^2+k^2)}

SP=2\sqrt{h^2+k^2}

step 3

<em>Find the ratio  RP/SP</em>

\frac{RP}{SP}=\frac{6\sqrt{h^2+k^2}}{2\sqrt{h^2+k^2}}

\frac{RP}{SP}=3

Part B. We have to determine the value of \frac{RP}{RS}

step 1

Find the distance RS

R(x,y),S(x+8h,y+8k)

RS=\sqrt{(x+8h-x)^2+(y+8k-y)^2}

RS=\sqrt{64h^2+64k^2}

RS=\sqrt{64(h^2+k^2)}

RS=8\sqrt{h^2+k^2}

step 2

<em>Find the ratio RP/RS</em>

\frac{RP}{RS}=\frac{6\sqrt{h^2+k^2}}{8\sqrt{h^2+k^2}}

\frac{RP}{RS}=\frac{3}{4}

mrs. hamilton worked for a real estate agency. she sold a house for $175,000. the agency's fee for the sale was 4% of the sales
topjm [15]
Selling Price of the house = $175 000

Agency Commission = 4% of $175000
Agency Commission = 0.04 x 175000 = $7000

Percentage of Hamilton's commission = 4725/7000 x 100 = 67.5%

----------------------
Answer: 67.5%
