The solution of x is x = 0, x =2 and x = -5

The equation is given as:

2x^3+6x^2-20x=0​

Factor out x

x(2x^2+6x-20)=0​

Split the equation

x = 0 or 2x^2+6x - 20=0​

Solve for x in 2x^2+6x - 20=0​

Expand the equation

2x^2 + 10x - 4x - 20 = 0

Factorize the equation

(2x - 4)(x +5) = 0

Split the equation

2x - 4 = 0 and x + 5 = 0

Solve for x

x =2 and x = -5

Hence, the solution of x is x = 0, x =2 and x = -5

Answer: The momentum of the truck before the collision is given by the formula:

p_i = m_i * v_i, where m_i is the mass of the object and v_i is its velocity.

The momentum of the truck before the collision is:

p_i (truck) = 3000 kg * 10 m/s = 30000 kg m/s

The momentum of the car before the collision is:

p_i (car) = 1000 kg * 0 m/s = 0 kg m/s

The total initial momentum of the system is the sum of the initial momenta of the truck and car:

p_i (total) = p_i (truck) + p_i (car) = 30000 kg m/s + 0 kg m/s = 30000 kg m/s

After the collision, the final momentum of the system is the sum of the final momenta of the truck and car:

p_f (total) = p_f (truck) + p_f (car)

Let's call the velocity of the truck after the collision v_f (truck). The final momentum of the truck is:

p_f (truck) = 3000 kg * v_f (truck)

The final momentum of the car is:

p_f (car) = 1000 kg * 15 m/s = 15000 kg m/s

Using the conservation of momentum, we can write an equation:

p_f (total) = p_i (total)

30000 kg m/s = p_f (truck) + p_f (car)

30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s

30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s

v_f (truck) = (30000 kg m/s - 15000 kg m/s) / 3000 kg = 7.5 m/s

So, the velocity of the truck immediately after the collision is 7.5 m/s.

Answer:

To prove that tan A = 12/5, we can use the identity that relates the sine and cosine of an angle to its tangent:

tan A = sin A / cos A

We are given that 0.5 * cos A = 13, so cos A = 26.

Substituting this value into the identity above, we get:

tan A = sin A / 26

We are also given that 12 sec A = 13, so sec A = 13/12 = 1.083333.

The reciprocal of sec A is cosec A, so cosec A = 1/1.083333 = 0.9230769.

The sine of an angle is the reciprocal of the cosecant of the angle, so sin A = 1/0.9230769 = 1.083333.

Substituting this value into the identity tan A = sin A / cos A, we get:

tan A = 1.083333 / 26 = 12/5

Therefore, tan A = 12/5.

i think it's 557/100, but i'm not sure that is its simplest form

Answer:557/100

Step-by-step explanation: 557 can be split into two parts: whole number(5) and decimal fraction(0.57). Therefore by expansion:

5.57=5 + 0.5 + 0.07 i.e five + five tenths + five hundredths

= 5 + 5/10 + 7/100 = 5 + (5/10 + 7/100) = 5 + 57/100 = 557/100

Answer:

a)  (-∞, -1) ∪ (-1, ∞)

b)  (-∞, -4) ∪ (-4, ∞)

c)  Vertical asymptote: x = -1

    Horizontal asymptote:  y = -4

Step-by-step explanation:

Given function:

\(f(x)=\dfrac{1}{x+1}-4\)

The domain of a function is the set of all possible input values (x-values).

When the denominator of a rational function is zero, the function is undefined.  

Rewrite the function as one fraction:

\(\implies f(x)=\dfrac{1}{x+1}-\dfrac{4(x+1)}{x+1}\)

\(\implies f(x)=\dfrac{1-4(x+1)}{x+1}\)

\(\implies f(x)=\dfrac{-4x-3}{x+1}\)

Set the denominator to zero and solve for x:

\(\implies x+1=0\)

\(\implies x=-1\)

Therefore, the given function is undefined when x = -1, so its domain in interval notation is:

The range of a function is the set of all possible output values (y-values).

As the domain is restricted to (-∞, -1) ∪ (-1, ∞), the range is also restricted.

To find the range of a rational function, first solve the equation for x:

\(\implies y=\dfrac{1}{x+1}-4\)

\(\implies y+4=\dfrac{1}{x+1}\)

\(\implies (y+4)(x+1)=1\)

\(\implies x+1=\dfrac{1}{y+4}\)

\(\implies x=\dfrac{1}{y+4}-1\)

\(\implies x=\dfrac{1-(y+4)}{y+4}\)

Set the denominator of the resultant equation ≠ 0 and solve for y:

\(\implies y+4 \neq 0\)

\(\implies y \neq -4\)

Therefore, the range is the set of all real numbers other than y = -4:

A vertical asymptote occurs at the x-value(s) that make the denominator of a rational function zero.

Therefore, there is a vertical asymptote at x = -1.

As the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is the result of dividing the highest degree term of the numerator by the highest degree term of the denominator.

\(\implies f(x)=\dfrac{-4x-3}{x+1}\)

Therefore, there is a horizontal asymptote at:

There are no slant asymptotes as there is a horizontal asymptote.

Answer: The description of that transformation is the triangle is rotated 90 degrees clockwise. Then, it's moved to the right TWICE. Finally, you go down 2 times.

Step-by-step explanation:

Hope this helps :)

triangle B is in dofferent orientation from triangle B so we know it was either mirrored or rotated. Triangle B isnt in the exact opposite orientation as A so we know it wasnt mirrored. So we now know that it was rotated and know we have to find the point of rotation. we can tell that the rotation was 270 degrees anti clockwise since it cant be clockwise because no points of rotation match. since we know triangle A was rotated 270 degrees anti clockwise to get triangle B we cant find the point of rotation by seeing which point works and if we test the points we will see that (0;-1) is the point of rotation. So triangle A was rotated 270 degrees anti clockwise on the point (0;-1) to make triangle B

What is linear regression ?

Linear regression is a statistical method that is used to establish the relationship between two variables, usually represented as a straight line. It is used to determine the extent to which one variable is dependent on the other variable, and to make predictions based on this relationship.

Using linear regression, we want to find the equation of the line of best fit in the form y = mx + b, where m is the slope and b is the y-intercept.

First, we need to calculate some sums:

∑x = 28

∑y = 45

∑xy = 224

∑x² = 140

∑y²= 275

Using these sums, we can calculate the slope m:

m = (n∑xy - ∑x∑y) / (n∑x² - (∑x)²)

m = (7(224) - (28)(45)) / (7(140) - (28)^2)

m = 1.19

Now we can use the slope to calculate the y-intercept b:

b = (∑y - m∑x) / n

b = (45 - (1.19)(28)) / 7

b = -0.37

Therefore, the equation of the line of best fit is y = 1.19x - 0.37.

Circles that overlap have some characteristics, but circles that do not overlap do not. Venn diagrams are useful for showing how two concepts are related and different graphically. They have long been acknowledged for their value as teaching resources. Venn diagrams have been used in elementary-level lesson plans and the introduction to logic curricula worldwide Venn diagrams are helpful for displaying the relationships between several ideas or elements. They can quickly demonstrate how objects are alike or unlike as well as where and how they overlap. A Venn diagram's center, which is where two or more circles meet, frequently indicates some nexus or central concept that may be broken down into the various other circles, with the labels on the outer sections representing more abstract and separate concepts than those near the center. The overlapped regions can also be utilized to highlight the similarities between two seemingly unrelated settings. The sample diagram below, for instance, shows that while the urban and rural environments are diverse and have their own range of activities, they do share athletic events.
