<u>Answer</u>:
The discriminant of 3 x squared minus 10 x = negative 2 is 76
<u>Explanation</u>:
<u>Given</u>:
..........(1)
We can find out the discriminant by using the formula
So from the equation (1)
We have b = -10
a= 3
c= 2
Now put all these values of a,b and c in the formula of discriminant to find out the value of D
So
D=76
So the discriminant of the given quadritic equation = 76
Answer: Third option.
Step-by-step explanation:
According to the data information given in the exercise, you know that "d" represents number of miles Mr. Dillion traveled and "h" represents the number of hours Mr. Dillion drove.
Given the following equation:
You must substitute into the equation and then you must evaluate, in order to calculate the number of miles Mr. Dillion will travel in 6 hours.
Then, you get this result:
We can write an algebra formula so let the number be Y
Y x 75% = 15
Y = 15/75% (aka 15/0.75)
therefore Y = 20
