What is the discriminant of 3x² 2x 1 0?
Equation 3x2 + 2x + 1 = 0's discriminant is -8.
D = b2 - 4ac is the quadratic equation's discriminant.
where a, b, and c are the coefficients of the equation in the form ax² + bx + c = 0.
Therefore,
D = b² - 4ac
= 2² - 4(3)(1)
= -8
The discriminant of a quadratic equation is found by using the formula D = b² - 4ac, where a, b, and c are the coefficients of the equation in the form ax² + bx + c = 0. In this case, a = 3, b = 2, and c = 1, so the discriminant would be D = b² - 4ac = 2² - 4(3)(1) = -8.

The probability that it rains in London on any particular day is 0.5.
If it rains then the probability of it raining the following day decreases to 0.15.
Consider the next two days. What is the probability it rains on both days?
The probability it rains on both days is 0.175
How to determine the probability it rains on both days?From the question, we have the following parameters that can be used in our computation:
P(Rain) = 0.5
P(Rain next day) = P(Rain) - 0.15
The probability it rains on both days is then calculated as
P(Rain both days) = P(Rain next day) * P(Rain)
Substitute the known values in the above equation, so, we have the following representation
P(Rain both days) = 0.5 * (0.5 - 0.15)

Step-by-step explanation:
A company that makes chow mix and use 138 lb of peanuts for every 2/3 lb of reasons they make 245 lb of trail mix using only peanuts and raisins. How many pounds of peanuts do they use?
The number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.
To solve this problem, you can set up a system of equations to represent the given information. The first equation represents the fact that the company uses 138 pounds of peanuts for every 2/3 pound of raisins:
138 pounds peanuts / 2/3 pound raisins = x pounds peanuts
The second equation represents the fact that the company makes 245 pounds of trail mix using only peanuts and raisins:
x pounds peanuts + y pounds raisins = 245 pounds trail mix
To solve for the number of pounds of peanuts used, you can substitute the first equation into the second equation:
(138 pounds peanuts / 2/3 pound raisins) + y pounds raisins = 245 pounds trail mix
Multiplying both sides of the equation by 2/3 to eliminate the fraction, we get:
138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds trail mix)
Combining like terms, we get:
138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds)
Simplifying the right side of the equation, we get:
138 pounds peanuts + (2/3)y pounds raisins = 160 pounds
Subtracting 138 pounds from both sides of the equation, we get:
(2/3)y pounds raisins = 160 pounds - 138 pounds
Simplifying the right side of the equation, we get:
(2/3)y pounds raisins = 22 pounds
Dividing both sides of the equation by 2/3, we get:
y pounds raisins = (3/2)(22 pounds)
Simplifying the right side of the equation, we get:
y pounds raisins = 33 pounds
Substituting this value into the first equation, we get:
138 pounds peanuts / 2/3 pound raisins = 33 pounds raisins
Multiplying both sides of the equation by 2/3, we get:
138 pounds peanuts / (2/3)(33 pounds raisins) = 33 pounds raisins
Simplifying the right side of the equation, we get:
138 pounds peanuts / 22 pounds raisins = 33 pounds raisins
Dividing both sides of the equation by 22 pounds raisins, we get:
138 pounds peanuts / 22 pounds raisins / 33 pounds raisins = 33 pounds raisins / 22 pounds raisins
Simplifying the equation, we get:
6 pounds peanuts / 1 pound raisins = 33 pounds raisins / 22 pounds raisins
This equation shows that for every 1 pound of raisins the company uses, they use 6 pounds of peanuts.
Therefore, the number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

138 pounds peanuts / 2/3 pound raisins = x pounds peanuts
The second equation represents the fact that the company makes 245 pounds of trail mix using only peanuts and raisins:

(138 pounds peanuts / 2/3 pound raisins) + y pounds raisins = 245 pounds trail mix
138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds trail mix)
138 pounds peanuts + (2/3)y pounds raisins = (2/3)(245 pounds)
138 pounds peanuts + (2/3)y pounds raisins = 160 pounds
(2/3)y pounds raisins = 160 pounds - 138 pounds
(2/3)y pounds raisins = 22 pounds
y pounds raisins = (3/2)(22 pounds)
y pounds raisins = 33 pounds
138 pounds peanuts / 2/3 pound raisins = 33 pounds raisins
138 pounds peanuts / (2/3)(33 pounds raisins) = 33 pounds raisins
138 pounds peanuts / 22 pounds raisins = 33 pounds raisins
138 pounds peanuts / 22 pounds raisins / 33 pounds raisins = 33 pounds raisins / 22 pounds raisins
6 pounds peanuts / 1 pound raisins = 33 pounds raisins / 22 pounds raisins
This equation shows that for every 1 pound of raisins the company uses, they use 6 pounds of peanuts.
Therefore, the number of pounds of peanuts the company uses is 6 pounds peanuts/1 pound raisins * 33 pounds raisins = 198 pounds peanuts.

Given,
Point A (7, 1) is reflected over the point (4, 0)
We know that,
The reflected point will be equidistant from the point over which it is reflected as the original point and in the same line as the original point and the reflected point.
Find the difference between the x and y values of the given points
For x value = 4 - 7 = -3
For y value = 0 - 1 = -1
Now, add the value to the reflection point.
x - axis : 4 +(-3) = 1
y - axis : 0 + (-1) = -1
Hence, the coordinates of point B is (1, -1)
