Answer:

0 real solutions

Step-by-step explanation:

The discriminant (D) is given by the formula:

D=b^2-4ac

Where a,b, and c are gotten from the standard form of a quadratic equation, which is  ax^2+bx+c=0

The equation given is  3x^2-5x+4=0

<em>From this we can say that a = 3, b = -5, & c = 4. Plugging these into the discriminant formula we get:</em>

D=b^2-4ac\\D=(-5)^2-4(3)(4)\\D=-23

<u>There are 3 things that we can find from the value of discriminant:</u>

1. If D=0, there are 2 equal, real roots

2. if D>0, there are 2 distinct real roots

3. if D<0, there are no real roots, rather 2 imaginary roots

Since the value of the discriminant is negative (D<0), we can say that there are no real solutions for the equation given.

Answer:

<h2>0</h2>

Step-by-step explanation:

\text{Use the discriminant:}\\\\ax^2+bx+c=0\\\\\Delta=b^2-4ac\\\\\text{If}\ \Delta>0\ \text{then the equation has two real solutions:}\ x=\dfrac{-b\pm\sqrt\Delta}{2a}\\\text{If}\ \Delta=0\ \text{then the equation has one real solution:}\ x=\dfrac{-b}{2a}\\\text{If}\ \Delta

\text{We have the equation:}\\\\3x^2-5x+4=0\\\\a=3,\ b=-5,\ c=4\\\\\Delta=(-5)^2-4(3)(4)=25-48=-23

28 - 9m = 6 + 2m<br><br><br><br><br> —————————<br> M=?
Yuliya22 [10]

Answer:

m = 2

Step-by-step explanation:

first u move 9m to the other side of the equal side and add it to 2m to get 28 = 6+11m

then u subtract 6 on both sides to get 22 = 11m

then u divide both sides by 11 to get 2 = m

Sine, cosine, and tangent to calculate the height of the buildings in the diagram below.
DiKsa [7]

Answer: Around 68.0858 m

Step-by-step explanation:

  • Set the height of 37°-53°-90° triangle as x
  • Set the height of 50°-40°-90° triangle as y
  • The horizontal side both triangles share = 35

To find x                            To find y  

tan(37)=\frac{x}{35} \\\\35tan(37)=x\\\\x=26.37439...                     tan(50)=\frac{y}{35} \\\\35tan(50)=y\\\\y=41.7113757...

To find the height of the building, add the x-value and y-value:

x+y=26.3744+41.7114=68.0858  

<em>I hope this is correct o_o</em>

The_____ is an incremental development process that has less emphasis on team coding and more emphasis on limiting a project's s
denis-greek [22]

Answer:

D) Agile methodology

Step-by-step explanation:

Agile methodology can be described as a technique employed to to manage a project by a team whereby the project is divided into several stages and thereby necessitate the need for a constant collaboration among the stakeholders as well as continuous improvement and iteration at each of the stages of the project.

The description of the nature of the utilization of the end product and the definition of problem to be solved by the clients indicates the commencement of the agile methodology. The aim is to ensure the expectations of the clients are made clear to the project team.

After the commencement of the work, an incremental development process of planning, executing, and evaluating is constantly repeated by the teams with little emphasis on team coding and more emphasis one limiting the scope of the project so that the final deliverable of the project is altered with the sole aim of meeting the requirements of the customer better.

Therefore, the correct option is D, that is the <u>agile methodology</u> is an incremental development process that has less emphasis on team coding and more emphasis on limiting a project's scope. ​
