Answer:

-28

Step-by-step explanation:

It is -28 because you have two numbers with a (-) sign. Therefore you add the both of them together instead of subtracting.

19+9=28 then add the negative sign. -28

Answer:

-28

Step-by-step explanation:

If something good (+) happens to a good (+) person, that is good (+).

If something bad (-) happens to a bad (-) guy, that is good (+).

If something good (+) happens to a bad (-) guy, that is bad (-).

If something bad (-) happens to a good (+) guy, that is bad (-).

A positive and a positive = a positive

A negative and a negative = a positive

A positive and a negative = a negative

A negative and a positive = a negative

- - = +

- * - = +

+ + = +

+ * + = +

- + = -

- * + = -

+- = -

+ * - = -

+ -19 = - 19

-9 - 19

-9 - 19 = -28

Find all the zeroes of the polynomial function f(x)=x^3-5x^2+6x-30 using synthetic division.

WITCHER [35]

Write the coeeficientes of the polynomial in order:

| 1   - 5   6   - 30
|
|
|
------------------------

After some trials you probe with 5

   | 1   - 5    6     - 30
   |
   |
5 |        5      0       30
-----------------------------
   1    0      6        0 <---- residue

Given that the residue is 0, 5 is a root.

The quotient is x^2 + 6 = 0, which does not have a real root.

Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.

Suppose that you are headed toward a plataeu 70m high. If the angle of elevation to the top of the platau is 35 degree how far a

SIZIF [17.4K]

Answer:

The distance you are from the base of plateau = $99.97\ m\approx 100\ m$

Step-by-step explanation:

Given:

Height of plateau = 70 m

Angle of elevation to the top of plateau = 35°

To find the distance you are from the base of plateau.

We will construct a triangle ABC to model the given situation. The triangle would be a right triangle for which we know an angle and its opposite side. We need to find the adjacent side of the triangle.

We will apply trigonometric ratio to find the adjacent side.

$\tan\theta=\frac{Opposite\ Side}{Adjacent\ Side}$
