Step-by-step explanation:

x = - 5

y = 2 . 5 ( - 5 ) - 8

= 2 . - 25 - 8

= - 50 - 8

y = - 58

x = 0

y = 2 . 5 ( 0 ) - 8

= 2 . 0 - 8

= 0 - 8

y = - 8

x = 5

y = 2 . 5 ( 5 ) - 8

= 2 . 25 - 8

= 50 - 8

y = 42

x = 10

y = 2 . 5x - 8

= 2 . 5 ( 10 ) - 8

= 2 . 50 - 8

= 100 - 8

y = 92

Answer:

-20.5

-8

4.5

17

Step-by-step explanation:

y = 2.5x - 8

x = -5

y = 2.5(-5) - 8

y = -12.5 - 8

y = -20.5

x = 0

y = 2.5(0) - 8

y = 0 - 8

y = -8

x = 5

y = 2.5(5) - 8

y = 12.5 - 8

y = 4.5

x = 10

y = 2.5(10) - 8

y = 25 - 8

y = 17

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6
vodka [1.7K]

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial -3x^4+2x^3-x^2+6 through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial -3x^4+2x^3-x^2+6 .

(x+1)(-3x^3)=-3x^4-3x^3

We subtract this from the original -3x^4-(-3x^4)+2x^3-(-3x^3)-x^2+6.

This leaves 5x^3-x^2+6. We repeat the step above.

(x+1)(5x^2)=5x^3+5x^2.

We subtract this from 5x^3-(5x^3)-x^2-(5x^2)+6=-6x^2+6. We repeat the step above.

(x+1)(-6x)=-6x^2-6x.

We subtract this from -6x^2-(-6x^2)+0x-(-6x)+6=6x+6. We repeat the step above.

(x+1)(6)=-6x+1.

We subtract this from 6x-(6x)+6-(6)=0. There is no remainder. This means (x+1) is a factor.

Please help I will give brainliest.
gogolik [260]

Answer:

Options: 1, 4 & 6

Step-by-step explanation:

Yes:

1. -1(x-1)^{2} +9=-1(x^{2} -2x+1)+9=-x^{2} +2x-1+9=-x^{2} +2x+8

4. -x^{2} +2x+8

6. (x+2)(4-x)=2x-x^{2} +8=-x^{2} +2x+8

No:

2. -(x-9)^{2} +1=-(x^{2} -18x+81)+1=-x^{2} +18x+81+1=-x^{2} +18x+82

3. x^{2} +2x-8

5. (x+2)(x-4)=x^{2} -2x-8

Hope this helps

A cylindrical tank holds 20,000 gallons of water, which can be drained from the bottom of the tank in 20 minutes. The function g
IgorLugansk [536]
You didn't include the function.

If the function is, V = 20,000 (1 - t/20)^2, as you can see, for t = 20, V = 0

Then I am going to show you the work with that function, and you can use the same procedure with your own fucntion.


The rate of change of the volume is the derivative of the function with respect to the time.

[dV/dt] = 20,000 *2 [1 -t/20] * [-1/20] = - 2000 [1 - t/20] = 2000[t/20 - 1]

At t = 3

dV/dt = 2000[3/20 - 1] = -1700 gallons / min

The negative sign mean decreasing.

The answer is - 1700 gallons / min

Now, for the same function, if the time is t = 2, you would obtain one of the results of the list of options.

dV/dt = 20,000 [2/20 - 1] = -1800 gallons/minute, which is the option D of the list.
