Compute the area of triangle, if x equals 3 less than 6

The graph of the quadratic function is on the image at the end.

Here we have the quadratic function:

f(x) = (x + 1)*(x - 5)

To graph this, we need to find some points of the parabola and then connect them.

So let's evaluate the function.

if x = -1

f(-1) = (-1 + 1)*(-1 - 5) = 0

if x = 0

f(0) =  (0 + 1)*(0 - 5) = -5

if x = 1

f(1) =  (1 + 1)*(1 - 5) = 2*-4 = -8

if x = 5 then:

f(5) =   (5 + 1)*(5 - 5) = 0

So we have the points (-1, 0), (0, -5), (1, -8) and (5, 0).

With these we can graph the parabola (you can try to find more points to get a better graph).

probability 0.579 when X=0,

probability 0.347 when X =1

probability 0.069 for X = 2

probability 0.005 when X = 3.

The random variable X represents the number of times the number '2' is rolled when three dices are rolled.

X represents the values from 0 (when no '2' is rolled) to 3 (when all three dices show '2'.

Probabilities for each case, use the binomial probability formula, we, have,

P(X = a) =ⁿCₐ × pᵃ × (1-p)ⁿ⁻ᵃ

n = Number of trials (in this case, n = 3)

a = Number of successes (here, 'a' ranges from 0 to 3).

p = Probability of success (rolling a '2' on a single die)

p = 1/6

Required probabilities for each possibility is,

P(X = 0) = (³C₀) × (1/6)^0 × (5/6)^3

             = 125/216

             ≈ 0.579

This is how we simplify these expressions.

vector u can be written as a linear combination of the vectors in set S with the scalars a = 1 and b = 0.

To write vector u as a linear combination of the vectors in set S, we need to find scalars a and b such that:

u = a[1] + b[0]

Substituting the values of vector u and the vectors in set S into this equation, we get:

[1] = a[1] + b[0]

This equation can be simplified to:

[1] = [a] + [0]

Since the scalar b is being multiplied by the zero vector, it will always equal the zero vector, and can therefore be eliminated from the equation. This leaves us with:

[1] = [a]

We can see that the scalar a must equal 1 in order for this equation to be true. Therefore, vector u can be written as a linear combination of the vectors in set S as follows:

u = 1[1] + 0[0]

In conclusion, vector u can be written as a linear combination of the vectors in set S with the scalars a = 1 and b = 0.

There are no values of x that satisfy the equation -6-(4x)/(x+2)=(8)/(x+2).

To find the values of x for the equation -6-(4x)/(x+2)=(8)/(x+2), we need to follow the following steps:

Multiply both sides of the equation by (x+2) to eliminate the fractions:
(x+2)(-6-(4x)/(x+2))=(x+2)(8)/(x+2)

Simplify the equation:
-6(x+2)-4x=8

Distribute the -6:
-6x-12-4x=8

Combine like terms:
-10x-12=8

Add 12 to both sides:
-10x=20

Divide both sides by -10:
x=-2

However, we need to check our answer to make sure it does not result in a zero denominator in the original equation. If we plug in x=-2 into the original equation, we get a zero denominator, which is not allowed. Therefore, there are no values of x that satisfy the equation.

The estimate is that there were 30 million internet hosts in the year 1998.

Exponential growth is a function that shows an increase within a population that occurs at the same rate over time.

If the number of internet hosts increased by 100% per year, it means that it doubled every year. Therefore, we can use the formula for exponential growth to estimate the number of internet hosts in future years.

Let x be the number of years after 1993, and let H(x) be the number of internet hosts in year y. Then, we have:

H(x) = 1,313,000 * 2ˣ

To estimate the year when there were 30 million internet hosts, we need to solve the following equation for x:

H(x) = 30,000,000

Substituting the formula for H(y), we get:

1,313,000 * 2ˣ = 30,000,000

Dividing both sides by 1,313,000, we get:

2ˣ = 30,000,000 / 1,313,000

Taking the logarithm of both sides with base 2, we get:

x = log2(30,000,000 / 1,313,000)

Using a calculator, we get:

x ≈ 5.2

Therefore, the estimate for the year when there were 30 million internet hosts is: 1993 + 5.2 ≈ 1998.2

Hence, the estimate is that there were 30 million internet hosts in the year 1998.

The equation of the parallel line is y = -4x - 23.

To find the equation of the perpendicular line that passes through (-7, 5), we need to first find the slope of the given line y = -4x + 6. The slope of this line is -4. The slope of a perpendicular line is the negative reciprocal of the original slope, so the slope of the perpendicular line is 1/4.

Next, we can use the point-slope form of an equation to find the equation of the perpendicular line:

y - y1 = m(x - x1)

y - 5 = (1/4)(x - (-7))

y - 5 = (1/4)(x + 7)

y = (1/4)x + 9/4 + 5

y = (1/4)x + 29/4

The equation of the perpendicular line is y = (1/4)x + 29/4.

To find the equation of the parallel line that passes through (-7, 5), we can use the same slope as the original line, -4, and the point-slope form of an equation:

y - y1 = m(x - x1)

y - 5 = -4(x - (-7))

y - 5 = -4(x + 7)

y = -4x - 28 + 5

The polynomial  3x³ - 4x² + 9x - 12 as a product of binomials is (3x - 4)(x² + 3).

To rewrite the polynomial 3x³ - 4x² + 9x - 12 as a product of binomials, we need to factor the polynomial. One method to do this is by grouping. Here are the steps:

1. Group the first two terms and the last two terms: (3x³ - 4x²) + (9x - 12)
2. Factor out the common factor from each group: x²(3x - 4) + 3(3x - 4)
3. Notice that (3x - 4) is a common factor in both groups, so we can factor it out: (3x - 4)(x² + 3)
4. Now we have the polynomial rewritten as a product of binomials: (3x - 4)(x² + 3)

Step-by-step explanation:

Assuming that the number of ingredients per pie is constant, we can write an expression for the total number of ingredients and pies baked in the two years as:

Total number of ingredients = (129 x ingredients per pie) + (b x ingredients per pie)

Total number of pies baked = 129 + b

So, if we let "i" represent the number of ingredients per pie, we can write the expression as:

Total number of ingredients = (129 x i) + (b x i)

Total number of pies baked = 129 + b

Note that without knowing the value of "i," we cannot simplify this expression any further.

The restriction on the variablex is that it must be greater than or equal to 1/3. If x is less than 1/3, the expression √6x-2 will not be a real number.

The restrictions on the variablex in the expression √6x-2 are determined by the fact that the square root of a negative number is not a real number. Therefore, the expression under the square root must be greater than or equal to zero. This gives us the following inequality:

6x-2 ≥ 0

Solving for x, we get:

6x ≥ 2

x ≥ 2/6

x ≥ 1/3

We must use the provided values in the table to determine the equation of the linear relationship between x and P in order to determine how much money Emma would be paid on a day when she sold 7 computers.

The first two data values can be used to determine the line's slope:

slope is equal to (145 - 105) / (3 - 1) / (P2 - P1) / (x2 - x1), or 20.

Next, we can determine the equation of the line using the point-slope form of the equation of a line:

P - P1 Equals m(x - x1) (x - x1)

P - 105 = 20(x - 1) (x - 1)

P = 20x + 85

To determine Emma's total pay, we can finally enter x = 7 into the equation:

Step-by-step explanation:

To solve this expression, we need to perform the division in the correct order, following the rules of mathematical operations. We can simplify the expression as follows:

(-168) ÷ (-14) ÷ (-3) = (-168) ÷ [(-14) x (-3)] [dividing by a negative number is the same as multiplying by its reciprocal]

= (-168) ÷ 42

= -4

Therefore, the quotient of (-168) ÷ (-14) ÷ (-3) is -4.

The expression can be explained as the trigonometric function of an angle as follows sin(15).

The given expression can be simplified using the trigonometric identity for the sine of the difference of two angles:

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

Substituting the given values for a and b, we get:

sin(9 - (-6)) = sin(9)cos(-6) - cos(9)sin(-6)

Simplifying further, we get:

sin(15) = sin(9)cos(6) - cos(9)sin(-6)

Therefore, the given expression can be expressed as a trigonometric function of one angle as follows:

sin(15) = sin(9)cos(6) - cos(9)sin(-6)

-sin(15) = cos(9)sin(-6) - sin(9)cos(6)

Tower B is 2.34 miles far from the point on the road closest to the fire.

The point on the road closest to the fire can be found by drawing a line perpendicular to the road that passes through the fire location. Let x be the distance from tower B to this point. Then, using trigonometry, we can find that the distance from tower A to the fire location is x/tan(22) and the distance from tower B to the fire location is (5 - x)/tan(37). Since the fire location is the same from both towers, these distances must be equal, so we can set up the equation x/tan(22) = (5 - x)/tan(37) and solve for x, which is approximately 2.34 miles.

To sketch the fire location, draw a straight road with two fire towers located 5 miles apart. From tower A, draw a line at an angle of 22 degrees towards the north side of the road to represent the direction of the fire location. From tower B, draw a line at an angle of 37 degrees towards the same side of the road. The point where these two lines intersect represents the location of the fire.

The linear speed of the circle is 2.125 cm/s and the angular speed of the circle is 0.1012 rad/s.

The linear speed of the circle can be found by calculating the length of the arc traveled in 25 seconds. The length of an arc is given by the formula L = rθ, where r is the radius of the circle and θ is the central angle in radians. Converting the given angle from degrees to radians, we have:

θ = 145 degrees * π/180 = 2.53 radians

Substituting the values into the formula, we get:

L = 21 cm * 2.53 = 53.13 cm

Therefore, the linear speed of the circle is:

v = L/t = 53.13 cm/25 s = 2.125 cm/s

The angular speed of the circle can be found by dividing the central angle by the time taken to travel that angle. Therefore, the angular speed of the circle is:

ω = θ/t = 2.53 radians/25 s = 0.1012 rad/s

Hence, the linear speed of the circle is 2.125 cm/s and the angular speed of the circle is 0.1012 rad/s.
