Answer 1
A is the answer to your question
Answer 2

Displacement means the distance traveled on a straight line to get to a certain destination. The interpretation of the given equation is option (a):

Given that:

[tex]f(x) = (x + 1)(x - 2)(x - 3)[/tex]

First, we calculate how far the student traveled to arrive at the school.

This means that we calculate f(0).

So, we have:

[tex]f(0) = (0 + 1)(0 - 2)(0 - 3)[/tex]

[tex]f(0) = ( 1)( - 2)( - 3)[/tex]

[tex]f(0) = 6[/tex]

The student walked 6km to school

When x = 2, it means:

[tex]f(x) = (x + 1)(x - 2)(x - 3)[/tex]

[tex]f(2) = (2 + 1)(2-2)(2 -3) = 0[/tex]

This means that the student got to school after 2 minutes

When x = 3, it means

[tex]f(x) = (x + 1)(x - 2)(x - 3)[/tex]

[tex]f(3) = (3 + 1)(3-2)(3 -3) = 0[/tex]

This means that the student walked away, turned back and got to school after 3 minutes.

From the given options, option (a) fits the above description.

A. 21+7
B. -27 +10;
C. 14 +6;
D. 8 +41

Answers

The complex expression (i-3) +6i-3(8 - i) when simplified is -27 + 10i

How to simplify the complex expression

From the question, we have the following parameters that can be used in our computation:

(i-3) +6i-3(8 - i)

Express properly

So, we have

(i - 3) + 6i - 3(8 - i)

When the brackets are opened, we have

(i - 3) + 6i - 3(8 - i) = i - 3 + 6i - 24 + 3i

Collect the like terms

So, we have

(i - 3) + 6i - 3(8 - i) = - 3  - 24 + i + 6i + 3i

Evaluate the like terms

So, we have

(i - 3) + 6i - 3(8 - i) = -27 + 10i

Hence, the complex expression when simplified is -27 + 10i

Explain how to solve 5x^2-3x=25 by completing the square. What are the solutions?

Answers

Answer:

x1 = √(509) /100 + 3/10

x2  = -√(509) /100 + 3/10

Step-by-step explanation:

We do completing the square as follows:

1. Put all terms with variable on one side and the constants on the other side.

5x^2 - 3x = 25

2. Factor out the coefficient of the x^2 term.

5(x^2 - 3x/5) = 25

3. Inside the parentheses, we add a number that would complete the square and also add this to the other side of the equation. In this case we add 9/100 and on the other  side we add 9/20.

5(x^2 - 3x/5 + 9/100) = 25 + 9/20

4. We simplify as follows:

5(x^2 - 3x/5 + 9/100) = 25 + 9/20

5(x - 3/10)^2 = 509/20

(x - 3/10)^2 = 509/100

x1 = √(509) /100 + 3/10

x2  = -√(509) /100 + 3/10
