-2x^2+5x-4=0 , find the discriminant
Answer:
The discriminant is -7
Step-by-step explanation:
The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:
[tex]b^2 -4ac[/tex]
Here
b is the co-efficient of x
a is the co-efficient of x^2
and c is the constant
Given equation is:
[tex]-2x^2+5x-4=0[/tex]
Here
a = -2
b = 5
c = -4
Putting the values in the formula for discriminant
[tex]= b^2 - 4ac\\= (5)^2 - 4(-2)(-4)\\= 25 - 32\\=-7[/tex]
As the discriminant is negative, the equation has no real solution.
Hence,
The discriminant is -7

Given the price of a DVD is $24.00 plus 8% sales tax.
we have to find the sales tax on this DVD in dollars and cents.
The sales tax is 8% can be calculated as
8/100 X $24
1.92
In cents
as one dollar equals 100 cents
∴ 1.92 dollar = $1.92 = 192 cents
Hence, sales tax is $1.92 or 192 cents.
So your answer is C!!

Imagine someone makes $30,000 a year and receives two paychecks per month. The employer withholds 13.9% of that in federal income tax. What is the amount of each paycheck after federal income tax has been taken out?
Answer:
Step-by-step explanation:
30,000/12= 2500
2500/2 checks per month= 1250 per check
1250*13.9%=173.75 per check in federal taxes
1250-173.75= $1076.25 per check after federal tax
The amount of each paycheck after federal income tax has been taken out is $1,076.25.
Calculation of the amount:The per month payment be like
[tex]= 30,000 \div 12[/tex]
= 2,500
Since there are two paycheck for each one it should be
[tex]= 2,500 \div 12[/tex]
= 1,250
Now there is 13.9% of federal income tax
So,
= 13.9% of 1,250
= 173,.75
Now the amount should be
= $1,250 - $173.75
= $1076.25
Hence, The amount of each paycheck after federal income tax has been taken out is $1,076.25.

Give evidence or explain your reasoning for your answer to example #4:
Answer:
I think it displays Newton's 3rd law.
Step-by-step explanation:
Newton's third law says: Every action has a reaction that is equal in force and opposite in direction.
the air from balloon exerts force opposite to the air's direction in the balloon, and the fore is equal, that's why the balloon moves upwards.

[tex]\sqrt{200\\[/tex]
Answer: 14.1421356237
Step-by-step explanation: We should know that 200 can be written in radical form (√200 = q × q = q2). To find the square root of 200, first you can ask yourself whether √200 is a perfect square, in which it isn’t because it doesn’t equal a whole number. Next, ask yourself if √200 is a rational or irrational number, in which it is an irrational number. After, determine whether √200 can be simplified, which in this case can be simplified to 200 = 10√2 which makes it easier to calculate the square root of 200. Lastly, the easiest and most boring way to calculate the square root of 200 is to use your calculator! Simply type in 200 followed by √x to get the answer. We did that with our calculator and got the following answer with 9 decimal numbers:
√200 ≈ 14.142135624

Answer: (-6,-9)
Step-by-step explanation: you probably don't wanna read this but in case someone asks you about it- first start by putting the first equation into graphing form, turning it into 2y=-3x+12.
then you can go ahead and multiply the second equation by two to get 2(y=1/2x-6), which is 2y=x-12.
next, just subtraction! 2y=-3x+12 minus 2y=x-12!
You get -4x=24, which leaves you to divide both sides by -4 to get x=-6!
now to put in x for the solution, you take a equation(either one) and put in x
[y=1/2(-6)-6]
[y=-3-6]
[y=-9]
so your points are (-6,-9)

what does t=
Answer:
t = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
10t - 19 = 7t - 14
Subtract 7t from both sides;
3t - 19 = -14
Add 19 to both sides;
3t = 5
Divide both sides by 3;
t = [tex]\frac{5}{3}[/tex]
