Answer:

-2x +4

Step-by-step explanation:

We can write the polynomial p(x) in terms of the factors (x+2) and (x-3) as ...

p(x) = (x+2)(x-3)q(x) +ax +b

Where ax+b is the remainder from division by x^2 -x -6 = (x+2)(x-3). The values of 'a' and 'b' can be found from ...

p(-2) = 8 = -2a +b

p(3) = -2 = 3a +b

Subtracting the first equation from the second gives ...

(3a +b) -(-2a +b) = (-2) -(8)

5a = -10

a = -2

Then the first equation tells us ...

8 = -2(-2) +b

4 = b

So, the remainder from division by (x^2 -x -6) is (-2x +4).

a rectangular patio has a perimeter of 60 feet. if the length of the patio is 3 feet less than twice the width, find the dimensi

Juli2301 [7.4K]

P = 2(L + W)
P = 60
L = 2W - 3

60 = 2(2W - 3 + W)
60 = 2(3W - 3)
60 = 6W - 6
60 + 6 = 6W
66 = 6W
66/6 = W
11 = W <=== the width is 11 ft

L = 2W - 3
L = 2(11) - 3
L = 22 - 3
L = 19 <=== the length is 19 ft

Answer:

P(x) = $-2x^{2}$ + 304x - 8510

x = 37 smallest B.E.P

Step-by-step explanation:

P = R - E

P = $-2x^{2}$ + 317 x

E = 13x + 8510

P = $-2x^{2}$ + 317 x - 13x - 8510

P(x) = $-2x^{2}$ + 304x - 8510

B.E.P.(X) where R=E

$-2x^{2}$ + 304 x - 8510 = 0

2(x-37)(x-115)

A ball is launched upward from a height 40 feet above ground level. The ball’s height at t seconds is given by -16t^2=128=40 .

Nesterboy [21]

Answer:

The ball will be at 100 feet at time x=0.5 sec and at time x=7.5 sec

Step-by-step explanation:

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

A ball is launched upward from a height 40 feet above ground level. the ball's height at t seconds is given by h(t)=-16t^2+128t+40 At what time(s) will the ball be at 100 feet?

we have

$h(t)=-16t^{2}+128t+40$
