What are the solutions of 3x² 6x 2 0?

Answer:

see the picture attached

Step-by-step explanation:

To graph this, we will count to a negative five on the graph. This means that we will move to the left five spaces and plot a point at (-5,0). Now, we will create a vertical line at -5 to encapsulate all of the values found at x = -5. This is essentially an infinite line, but the picture I included shows it on a 10 x 10 plane. Hope this helps!

Answer:

What is X= -5 graphed

Step-by-step explanation:

Graph x=-5 x = −5 x = - 5 Since x = −5 x = - 5 is a vertical line, there is no y-intercept and the slope is undefined.

The equation x(2x+3) = x² + 1 is the quadratic equation and the remaining equation (x²)² + 1 = 2x³, (x +  1) + 8 = (x²)(x²), and (x²)³ = (x³)⁴ are not in quadratic equation.

The term quadratic equation in math is defined as an equation containing one term in which the unknown is squared and no term in which it is raised to a power higher than 2.

Here we have to find the equation that was not in the form of the quadratic equation.

As per the definition, we have know that the quadratic equation must be in the form of

=> ax² + bx + c = 0

So, here we have to look into the given expression, then w e have identified that only the equation x(2x+3) = x² + 1 is in the quadratic form.

Because the quadratic equation only have the highest power value of 2.

And the remaining are not the quadratic equation.

Therefore, option (a), (b) and (d) are the resulting options.

Answer:

Below in bold.

Step-by-step explanation:

R(x) = 8x/(x + 19)

When x = -19 the denominator = zero so there is a vertical asymptote which is

x = -19.

If we divide 8x by x + 19 we get  8 remainder -152.

So horizontal asymptote is R(x) = 8.

As the degree of the numerator and denominator are the same ( both 1) there is no oblique asymptote.

The required rate of change of the surface area of the cube is 66 sq,feet/second.

The momentum of a variable is represented by the rate of change, which is used to mathematically express the percentage change in value over a specified period of time. R = (D2 - D1)/T is a general formula for calculating the rate of change.

[tex]\frac{V}{dt}[/tex] = 1327 cubic feet per second

volume(V) = 528528 cubic feet

We know that

V = a^3

528528 = a^3

a = 80.85

Differentiate w, r, t

[tex]\frac{V}{dt}[/tex] = 3a^2[tex]\frac{da}{dt}[/tex]

1327 = 3(80.85)^2da/dt

da/dt = 0.068

Now,

Surface area(S) = 6a^2

Differentiate w, r, t

dS/dt = 12a(da/dt)

dS/dt = 12(80.85)(0.068)

dS/dt = 66 Sq.feet/second

Thus, required rate of change of the surface area of the cube is 66.

The interval of increase for the given function is (-1 , 0) (0 , infinity).

The real-valued functions that tend to rise and decrease with changes in the value of the function's dependant variable are increasing and decreasing intervals of real numbers. You must ascertain the function's first derivative in order to identify intervals of rise and decline.

This is done to determine whether the function's sign is positive or negative. If the value of the function f (x) rises as the value of x rises, the function interval is said to be positive. Instead, if the value of the function f (x) drops as the value of x increases, the function interval is said to be negative.

The given function is:

C(x) = x1/5(x + 6)

Answer:

In this problem, we need to add a point to this graph which creates a right triangle with the given points.

The easiest way to do this is to find a point that is perpendicular to both of the points; more simply put, it has to have the x-coordinate of one of the given points and the y-coordinate of the other given point.

For example, adding the point (50, -14) to the graph satisfies this criteria, using the x-coordinate of (50, 25) and the y-coordinate of (130, -14). However, you could also use the y-coord of the first point and the x-coord of the second to add the point (130, 25). Both points in bold satisfy the criteria.

See the attached image for a graph of these points and the right triangles they create.

The three comparisons are Beta had a higher percentage of listeners than group alpha, Beta had a higher mean number of hours listening than group alpha and Beta had a higher range of number of hours listening than group alpha.

The first comparison states that the Beta group had a higher percentage of listeners than the Alpha group. This means that out of all the people who listened to the radio station that day, a larger proportion of them belonged to the Beta group, compared to the Alpha group.

The second comparison is saying that the Beta group had a higher mean number of hours listening than the Alpha group. This means that on average, people in the Beta group listened to the radio station for more hours than people in the Alpha group.

The third comparison states that the Beta group had a higher range of number of hours listening than the Alpha group. This means that the difference between the minimum and maximum hours of listening in the Beta group is larger than the Alpha group. Which means that the listeners of Beta group have a greater variability in terms of hours of listening than the Alpha group.

Step-by-step explanation:

You want to know the area of the isosceles triangle with congruent sides 4 units and base 6 units.

The perimeter of the triangle is ...

  P = 4 + 4 + 6 = 14

so the semiperimeter is ...

  s = P/2 = 14/2 = 7

By Heron's formula, the area of the triangle is ...

  A = √(s(s -a)(s -b)(s -c))

  A = √(7(7 -4)(7 -4)(7 -6)) = 3√7

The area of the triangle is 3√7 ≈ 7.937 square units.

The total cost of the entertainment center after six years, if Zebina must pay it off, would be $9,203.19.

When a person purchases an item using a deferred payment plan with interest, the total cost of the item will be greater than the original purchase price due to the added interest.

To calculate the total cost of the entertainment center after six years, we need to use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the total cost, P is the original purchase price, r is the annual interest rate (expressed as a decimal), n is the number of times the interest is compounded per year, and t is the number of years.

In this case, P = $2,798, r = 0.2195 (21.95% expressed as a decimal), n = 1 (because the interest is compounded annually), and t = 6. Plugging these values into the formula gives:

A = 2798(1 + 0.2195)^6

So the shortest distance he must walk to return to his house is approximately 10.8 miles.

The man walks 6 miles south and 9 miles east from his house. To find the shortest distance he must walk to return to his house, we need to use the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the man's walk can be represented by a right triangle, where the length of one side is 6 miles (the distance he walked south), the length of the other side is 9 miles (the distance he walked east), and the length of the hypotenuse is the shortest distance he must walk to return to his house.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse as:

hypotenuse = √(6^2 + 9^2) = √(36 + 81) = √117

What is the sum of the three angles in a triangle?

A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle.

Given that 2 angle A = 3 angle B = 6 angle C, we can set up the following equations:

2A = 3B

3B = 6C

We know that in any triangle, the sum of the three angles is always 180 degrees. We can set up the equation:

A + B + C = 180

We can substitute the values of A and B from the first two equations into this third equation:

2A + 3B + C = 180

2(3B) + 3B + C = 180

6C + C = 180

7C = 180

We can solve for C:

C = 180/7 = 25.7143

We can use the value of C to find the value of B:

B = 3C = 3(25.7143) = 77.1429

We can use the value of B to find the value of A:

A = 2B = 2(77.1429) = 154.2857
