Answer: C. (0,-9)

Step-by-step explanation: The y-intercept of the graphed function is (0,-9) because the y-intercept is where the point where the line meets with the y-axis, and the point where the line meets with the y axis is (0,-9)

Therefore the answer is

(0,-9)

Find an nth degree polynomial function with real coefficients satisfying the given conditions.
damaskus [11]

Step-by-step explanation:

Our roots are 3, and i so our roots form

will be

(x - 3)(x - i)

Since i is one root, it conjugate, must be the other.

so we have

(x - 3)(x - i)(x + i)

Simplify

( {x}^{2}  + 1)(x - 3)

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

So the function is

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

In the diagram of parallelogram HIJK below, the diagonals HJ and IK are perpendicular, as shown. If HJ is 10 inches long and IK
guapka [62]

Answer:

It is the hypotenuse of a right triangle with legs 5 and 12.

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. If the angle at which they meet is a right angle, then a right triangle is formed whose legs are half the length of each of the diagonals, and whose hypotenuse is the length of one side of the parallelogram (rhombus).

Here, the triangle's leg lengths are 5 and 12, so the Pythagorean theorem tells us the hypotenuse is ...

  √(5²+12²) = √(25+144) = √169 = 13

Since the perpendicular diagonals are 10 and 24 inches long, the side length of the rhombus must be 13 inches long.

HK must be 13 inches because the Pythagorean theorem applies and that's what it says.

When analyzing related data variables, how can one tell which one is the independent variable and which one is the dependent var
Hatshy [7]

Answer:

Dependent and independent Variable.

Step-by-step explanation:

Dependent and independent Variable.

  • The two variables in an experiment are independent and dependent variable.  
  • Usually, the dependent variable is denoted by y and the independent variable a re denoted by x_i
  • The dependent variable depends on independent variable in an experiment and thus cannot be controlled.
  • On the other hand we can change or control the independent variables to test effect on dependent variable.
  • As the independent variable are changed, we observe corresponding changes in the dependent variable.
  • Example: Let money spend be the dependent variable. It depends on an independent variable of shopping. We may control or change or shopping habits to see the changes in the money spent. Money spent totally depends in the amount f shopping done.

The table shows a linear function.
dem82 [27]

Answer:

see explanation

Step-by-step explanation:

A linear equation in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula using any 2 points from the table.

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (10, - 1) and (x₂, y₂ ) = (5,2)

m = \frac{2+1}{5-10} = \frac{3}{-5} = - \frac{3}{5}

Note the point (0, 5) is on the y- axis → c = 5

y = - \frac{3}{5} x + 5 ← equation representing the function
