First find Divisor

  • Two zeros are -3,-2

\\ \sf\longmapsto x^2-(-3-2)+(-3)(-2)

\\ \sf\longmapsto x^2+5x+6

Dividend given by

\\ \sf\longmapsto x^4-x^3-16x^2+4x+48

We know

\boxed{\sf Dividend=Divisor\times Quotient +Remainder}

  • Remainder is 0

\\ \sf\longmapsto Dividend=Divisor\times Quotient

\\ \sf\longmapsto Quotient=\dfrac{Dividend}{Divisor}

\\ \sf\longmapsto \dfrac{x^4-x^3-16x^2+4x+48}{x^2+5x+6}

\\ \sf\longmapsto x^2-6x+8

Now factor

\\ \sf\longmapsto x^2-6x+8=0

\\ \sf\longmapsto x^2-4x-2x+8=0

\\ \sf\longmapsto x(x-4)-2(x-4)=0

\\ \sf\longmapsto (x-4)(x-2)=0

\\ \sf\longmapsto x-4=0\:or\:x-2=0

\\ \sf\longmapsto x=4\:or\:x=2

Hence all zeros are

  • 2,-2,-3,4

Z varies jointly with x and y. when x=2 and y=3, z=60. what is the value of z when x=4 and y=9?
laiz [17]
<span>Z $ xy then Z = Kxy. When x = 2 and y = 3, and Z = 60, our constant of variation becomes 60 = K * 2 * 3 K = 10. Our constant of proportionality equals 10. We would need that in the second part of the equation. When x = 4 and y = 9, we have Z = 10 * 4 * 9 = 360</span>

Jordan has $275.00 in his bank account the bank will pay jordan 4% interest per year on the value of hois account if jordan does
Sunny_sXe [5.5K]

Answer:

\$286.00

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=1\ years\\ P=\$275.00\\r=4\%=4/100=0.04

substitute in the formula above

A=275.00(1+0.04*1)

A=275.00(1.04)

A=\$286.00

You roll a 6-sided die.<br> What is P(prime)?<br><br> Write your answer as a percentage.
sladkih [1.3K]

Answer:

50%

Step-by-step explanation:

Finding the probability of a single die roll requires little effort.

First, remember that by definition, a prime is an integer with precisely two factors: 1 and the number itself (which is why 1 does not qualify: it has only one factor). The numbers from 6 on down that fit the bill are 2,3,5. Since there are six sides, your answer is:

P(prime) = 3/6  = 1/2  = 50%

What are the zeros of A(x) = (x - 2)(x+ 7)? Select all that apply.
PtichkaEL [24]

Answer:

The zeros of the function are x=-7 and x=2

Step-by-step explanation:

we have

A(x)=(x-2)(x+7)

we know that

The zeros or roots of the function are the values of x when the value of the function is equal to zero (also is called the x-intercepts)

so

For A(x)=0

(x-2)(x+7)=0

Remember that

The <u><em>Zero Product Property</em></u> states that

if ab = 0, then either a = 0 or b = 0, or both a and b are 0

so

Let

(x-2)=0 ----> x=2

(x+7)=0 ----> x=-7

therefore

The zeros of the function are x=-7 and x=2
