Please help me with this math problem
Sergio [31]

Answer:

The table is a quadratic function

Step-by-step explanation:

Given

The attached table

Required

Tell if it is a quadratic function

The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.

(1) Subtract adjacent y values.

d_1=2 - 16 = -14

d_2=-2 - 2 = -4

d_3 = 4--2 = 6

d_4 = 20 - 4 = 16

(2) Subtract adjacent differences in (1) above

d_5 = d_2 - d_1 = -4 --14 = 10

d_6 = d_3 - d_2 = 6 --4 = 10

d_7 = d_4 - d_3 = 16 -6 = 10

Notice the calculated differences in (2) are the same.

<em>Hence, the table is a quadratic function</em>

A line goes through the points (7,8) and (3, 10). What is the slope of the line?
nekit [7.7K]

Answer:

slope = m = -\dfrac{1}{2}

Step-by-step explanation:

slope = m = \dfrac{y_2 - y_1}{x_2 - x_1}

slope = m = \dfrac{10 - 8}{3 - 7}

slope = m = \dfrac{2}{-4}

slope = m = -\dfrac{1}{2}

Sebastian simplified the expression -4,212 and got an answer of 4. Organize the
Butoxors [25]

The imaginary unit, i, which represents the square root of -1 raised to power 4 is 1

The organized steps are;

  • Choice E; Since i⁴ = 1
  • Choice B; Then -4·1 = -4
  • Choice F; Therefore, Sebastian is incorrect

Reason:

The given expression Sebastian simplified is; -4·i²¹²

The result Sebastian got = 4

The organized steps are presented as follows;

We have that 212 ÷ 4 = 3

Since i⁴ = 1

Then -4·1 = -4

Therefore, Sebastian is incorrect

The order of the steps are therefore;

Given  -4·i²¹²

Choice E; Since i⁴ = 1

Choice B; Then -4·1 = -4

Choice F; Therefore, Sebastian is incorrect
