The third equation is correct. The easiest way to solve a problem like this is to plug the x-values from the chart into the equations and see which one equals the y-value in the chart.

Consider the polynomial P(x)=x³+kx²+x+6.Find the value of k so that x+1 is a factor of P.

sergiy2304 [10]

Answer:

The value of k will be -4

Step-by-step explanation:

We have given polynomial $P(X)=x^3+kx^2+x+6$

It is given that x+1 is factor of the polynomial

And we have to find the value of k

As x+1 is the factor of polynomial so x+1 = 0 that is x = -1 will be the root of polynomial

So if we put x = -1 in the polynomial then the p(-1) will be zero

So $0=(-1)^3+k(-1)^2-1+6$

$k=-4$

So the value of k will be -4

Please help me for the brainliest answer

Zinaida [17]

Answer:

$5n^2$

Step-by-step explanation:

This is a quadratic sequence.

The nth term must have $n^2$ .

The sequence has a factor of $5$ .

$5n^2$

$5(1)^2=5\\5(2)^2=20\\5(3)^2=45\\5(4)^2=80\\5(5)^2=125$

Few terms to this sequence are:

5, 20, 45, 80, 125, 180, 245, 320, 405, 500, 605, 720, 845, 980, 1125, 1280, 1445, 1620, 1805, 2000, 2205, 2420, 2645, 2880, 3125, 3380, 3645, 3920, 4205, 4500, 4805, 5120, 5445, 5780, ...

Based on the Census, state A has 17 fewer electoral votes for president then state B. If the total number of electoral votes for

makkiz [27]

X = B.......x - 17 = A

x + x - 17 = 87
2x - 17 = 87
2x = 87 + 17
2x = 104
x = 104/2
x = 52........so state B has 52 electoral votes

x - 17 = A
52 - 17 = A
35 = A.....so state A has 35 electoral votes

Margo borrows $500, agreeing to pay it back with 3% annual interest after 14

Akimi4 [234]

Answer:

$\$17.50$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Final Interest to pay

P is the amount of money borrowed

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=\frac{14}{12}\ years\\ P=\$500\\r=3\%=3/100=0.03$

substitute in the formula above

$I=500(0.03)(\frac{14}{12})$

$I=\$17.50$

The circle below is centered at the origin and has a radius of 4. What is its equation?

Alecsey [184]

Answer:

C) x^2 + y^2 = 16

Step-by-step explanation:

<h2><u>Find the equation </u></h2>

since the radius is 4 this means that anywhere from the center of the circle to the edge of the circle is 4. hence :

place the horizontal line of the radius where y = 0 .

this means that if y = 0 , then x = 4

therefore :

x^2 + y^2

4^2 + 0^2

= 16

<h3><u>hence the answer is C ) x^2 + y^2 = 16</u></h3>
