Use the quadratic formula to solve the equation X(-2x – 11) = -3.
Replace m, n, and p with the correct values.
Answers
Answer:
I got it correct and this is the right answer:
The roots of the given quadratic equation are (- 11 ± √145)/4. Therefore, m = - 11, n = 145, and p = 4.
What is a quadratic equation?"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0)."
The given quadratic equation is:
x(- 2x - 11) = - 3
⇒ - 2x² - 11x = - 3
⇒ 2x² + 11x = 3
⇒ 2x² + 11x - 3 = 0
⇒ x = [- 11 ± {√(11²) - 4×2×(- 3)}]/(2 × 2)
⇒ x = [- 11 ± {√121 + 24}]/4
⇒ x = (- 11 ± √145)/4
Therefore, for the given quadratic equation, m = - 11, n = 145, and p = 4.

What is the missing degree measure of the third angle of the triangle below?
46°
56°
68°
90°
Answers
Answer:
56 degrees
Step-by-step explanation:
Hello there!
Remember the sum of the angles in a triangle is equal to 180
so to find the missing angle we subtract the given angles from 180
180 - 34 - 90 = 56
so we can conclude that the measure of the missing angle is 56 degrees
Note: the little square at the bottom left of the triangle indicates that the angle is a right angle. The measure of a right angle is 90 degrees so thats where the 90 came from
Answer:
third angle Δ = 56°hope it help you

The cosine function is the trigonometric function, so it is known as the periodic function.
The period of the given function is π/5. The option 4 is the correct option.
What is the period of the cosine function?
The cosine function is the trigonometric function, hence it is known as the periodic function.
The period of a function is the total interval in which the function repeats itself over and over again the of the function for a complete cycle. If,
[tex]f(x)=A\cos(Bx+C)+D[/tex]
Then the period of the cosine function can be given as,
[tex]I=\dfrac{2\pi}{|B|}[/tex]
Given information-
The given function in the problem is,
[tex]f(x)=\cos(10x)[/tex]
The above function is the cosine function. Let a cosine function of in with values of [tex]x[/tex] 0 to 2π.
Now the period of the periodic function is the interval of [tex]x[/tex] values in which the the cycle of graph repeats itself in both directions.
Compare the given function with above equation we get,
[tex]B=10[/tex]
Thus the period of the [tex]\cos (10x)[/tex] is,
[tex]I=\dfrac{2\pi}{|10|}\\I=\dfrac{\pi}{|5|}\\I=\dfrac{\pi}{5}\\[/tex]
Hence the period of the given function is π/5. Thus the option 4 is the correct option.

Answers
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3Answer:
Let's solve your equation step-by-step.
4x + x + 5 − 9 + x = −3 − 7 + x
Step 1: Simplify both sides of the equation.
4x + x + 5 − 9 + x = −3 − 7 + x
4x + x + 5 + −9 + x = −3 + −7 + x
( 4x + x + x ) + ( 5 + −9 ) = ( x ) + ( −3 + −7 )
( Combine Like Terms )
6x + −4 = x + −10
6x − 4 = x − 10
Step 2: Subtract x from both sides.
6x − 4 − x = x − 10 − x
5x − 4 = −10
Step 3: Add 4 to both sides.
5x − 4 + 4 = −10 + 4
5x = −6
Step 4: Divide both sides by 5.
5x / 5 = −6 / 5
x= −6 / 5
Answer:
x= −6 / 5
