Two numbers have a sum of - 6 and a product of 9.
Use the quadratic equation n^2 - 6n + 9 = 0 to determine the two numbers.
n2 - 6n + 9 = 0
Answer:
3, 3
Step-by-step explanation:
[tex]n^2 - 6n + 9 = 0 \\ n^2 - 3n - 3n+ 9 = 0 \\ n(n - 3) - 3(n - 3) = 0 \\ (n - 3)(n - 3) = 0 \\ n - 3 = 0, \: \: n - 3 = 0 \\ n = 3, \: \: n = 3[/tex]
Thus, the two numbers are 3, 3

Answer:
x= 4 and y=1
Step-by-step explanation:
to solve this you could either use substitution or elimination. elimination would be best her because both 'x's have the same number. subtract the equations from eahh other and solve for y, then substitute the y and solve for x
The system of equations are solved and x = -4 and y = 1
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
To solve the system of equations:
5x + y = -19 (Equation 1)
5x - 4y = -24 (Equation 2)
Let's use the elimination method in this case.
Step 1: Multiply Equation 1 by 4 and Equation 2 by 1 to eliminate y.
4(5x + y) = 4(-19)
5x - 4y = -24
20x + 4y = -76 (Equation 1 multiplied by 4)
5x - 4y = -24 (Equation 2 multiplied by 1)
Step 2: Add the equations together to eliminate y.
20x + 4y + 5x - 4y = -76 - 24
25x = -100
x = -100 / 25
x = -4
Step 3: Substitute the value of x into either Equation 1 or Equation 2 to solve for y.
5(-4) + y = -19 (Using Equation 1)
-20 + y = -19
y = -19 + 20
y = 1
Hence , the solution to the system of equations is x = -4 and y = 1

Simon wants to earn as many points as possible in one turn in a game. Two number cubes whose sides are numbered 1 through 6 are rolled. He is given two options for the manner in which points are awarded in the turn.
OPTION A: If the sum of the rolls is a prime number, Simon receives 15 points.
OPTION B: If the sum of the rolls is a multiple of 3, Simon receives 12 points.
Which statement best explains the option he should choose?
A. Simon should choose Option B. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
C. Simon should choose Option B. The mathematical expectation of this option is 4 and is the greater mathematical expectation of the two options.
D. Simon should choose Option A. The mathematical expectation of this option is 4 and is the greater mathematical expectation of the two options.
Answer: b. Simon should chose option a. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
Statement B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The probability that the sum of the rolls is a prime number:
P(sum is prime) = 15/36 =0.416
Expected number of points = 0.416×15 =6.25
Probability that f the sum of the rolls is a multiple of 3,
P(sum of rolls is multiple of 3) = 12/36 = 0.33
Expected number of points = 0.33×12 = 3.96
Thus, statement B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options is correct.

Find cosx and tanx
Answer:
Cos(x) = sqrt(55) / 8; tan(x) = 3/sqrt(55)
Step-by-step explanation:
Sine is opposite over hypotenuse. So we get that the opposite is 3 and the hypotenuse is 8. To find the adjacent (which we'll need for cosine and tangent), we can use pythagoras' theorem. Therefore, 8^2 = 3^2 + A^2, where A is the adjacent. A then must equal sqrt(64-9) = sqrt(55).
Cosine is adjacent over hypotenuse, which is then sqrt(55) / 8. Tangent is opposite over adjacent, which is then 3 / sqrt(55) or (sqrt55)*3/55
