Answer:

{-3/2, 4}

Step-by-step explanation:

Use synthetic division here.  If the remainder is 0, then the divisor is a root or solution.

Here we have x = -4.  Perform the synthetic division as follows:

-4       4     -10    -24

                 -16     108

------------------------------

          4      -26     84              The remainder is 84, which tells us -4 is NOT

                                                a root/solution.

Try -3/2 as divisor this time:

-3/2    4     -10    -24

                   -6    24

------------------------------

          4      -16       0            Remainder is 0, so -3/2 is a solution

Show in the same manner that 4 is a solution also.  Or determine whether x - 4 satisfies 4x - 16 = 0 (it does).

irinina [24]

Answer:

Don't accept A-G

Accept only A-E

Step-by-step explanation:

The company would those projects with a return of return equal to or higher than its cost of capital of 10.45%

Project A with a 12% return is acceptable.

Project B with a 11.5% rate of return is also acceptable

Project C has a  rate of return of 11.2% , hence acceptable.

Project D has 11% rate of return and it is therefore acceptable.

Project E has 10.7% return rate and it is acceptable.

Project F has a lower rate of return of 10.3%, hence rejected, as well as projects G

In ΔRST, m &lt; R = 104°, r = 20, and t = 10. Find the m &lt; S, to nearest degree.
Mrrafil [7]

9514 1404 393

Answer:

  47°

Step-by-step explanation:

The law of sines helps you find angle T. From there, you can find angle S.

  sin(T)/t = sin(R)/r

  sin(T) = (t/r)sin(R) = (10/20)sin(104°)

  T = arcsin(sin(104°)/2) ≈ 29°

Then angle S is ...

  S = 180° -R -T = 180° -104° -29°

  ∠S = 47°

Is a + b rational or irrational
Crank

Answer and fdaStep-by-step explanation:::

The answer depends on the numbers that are inputted for a and b.

If the numbers that are inputted for both a and b are rational, then a + b would be rational.

If the numbers that are inputted for both a and b are irrational, then a + b would be irrational.

If one of the variables is rational and the other is irrational, then a + b would be irrational.

(PLEASE HELP 15 POINTS I HAVE 7 MINS) explain your awnser what are the x- and the y-interceptions of 3x - 2y = 18
S_A_V [24]

The given equation is

3x-2y=18

x intercept

To find the x intercept, we have to plug 0 for y and solve for x.That is

3x-2(0)=18&#10;\\&#10;3x=18&#10;\\&#10;x=6

So x intercept is (6,0) .

y intercept

To find the y intercept , we have to plug 0 for x and solve for y. That is

3(0)-2y=18&#10;\\&#10;-2y=18&#10;\\&#10;y=-9

So the y intercept is (0,-9) .
