A quadratic equation can be written as: ax² + b.x + c =0
But if you know the values of the 2 roots x' and x", you can write it:
a(x-x')(x-x"), Since the roots are given ( x' = -4 and x" = -5) and also a (=2)
then the equation becomes:
2(x + 4)(x +5) =0

A consulting company claims that if job seekers attend the company's career development course, their chance of obtaining a job

mafiozo [28]

Answer:

Kevin should attend the career development course because the expected value of attending the career development course is greater than the expected value of not attending the career development course.

Step-by-step explanation:

If the consulting company claims that if job seekers attend the company's career development course their chance of obtaining a job is greatly increased is true then Kevin's chance of getting a job over the next year which is 76% will greatly increase.

The average salary in Kevin's desired profession is $61,207.11 if he attends the company career development course then there would be an increase of $7, 295.00. To sum, Kevin is expected to receive an annual salary of $68, 502.11. The cost of the course is only $2,763.00. If we subtract the cost from his annual salary: $68,502.11 - 2763 = $65, 739.11, there would be an increase on his salary. So, Kevin should attend the career development course because the expected value of attending the career development course is greater than the expected value of not attending the career development course.

Find the slope of the line passing through (1,3) and (-2,5)

Alenkasestr [34]

Hi there! :)

Step-by-step explanation:

$Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\frac{5-3}{(-2)-1}=\frac{2}{-3}$

Slope is -2/3

Final answer is -2/3

Hope this helps!

Thanks!

Question number 41 only . thank you

docker41 [41]

Answer:

x^2 +y^2

Step-by-step explanation:

Dude this is Pythragorean Theorem =)).

You may have missed this part of your lesson. It's ok and also not ok at the same time beacause pythagorean theorem is a meme.

Ok I'll explain once =)).

Thousands of years ago, a mathematician named Pythagore found out that if we have 3 squares, with one square's area equals to the sum of two other squares, then when we put the sides of the squares together to form a triangle , it'll always be a right triangle ( a triangle with one of its angle is 90°). A square area is measured by the length of its side multipled by itself. So he came up with the statement : In a right triangle, the length of the hypotenuse( the side that does not connect to the right angle) is equalled to the sum of squared other sides.

EG.

In this triangle, the right angle is ^ACB. If length of BC is a, length of AB is c, length of BC is a

I We have a formula :

I \ a^2 + b^2 = c^2

I \

I b \ c

I \

I______\

C a B

So now you can use pythagorean theorem to show off =)).

HOPE YOU LEARN WITH JOY AND HIGH GRADES !!!
