how to divide (x^2+5x-6)/(x-1)

Answer:

[tex]x=e^3+4[/tex] (exact)

x = 24.0855 (rounded)

Step-by-step explanation:

We need to remember 3 rules:

1. ln means log_e (ln is log base e)

2. [tex]a^b=x\\SameAS\\log_ax=b[/tex]

3. [tex]aLogx=Logx^a[/tex]

Now we can write the equation as:

[tex]3Ln(x-4)=9\\3Log_e(x-4)=9\\Log_e(x-4)^3=9[/tex]

Now, we can convert it to exponential and solve:

[tex]Log_e(x-4)^3=9\\(x-4)^3=e^9\\\sqrt[3]{(x-4)^3}=\sqrt[3]{e^9} \\ x-4=e^3\\x=e^3+4[/tex]

This is the exact value of x, in 4 decimal places (by using calculator), it would be

x = 24.0855

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition x = 2.5 when y = 100

k = yx = 100 × 2.5 = 250

y = [tex]\frac{250}{x}[/tex] ← equation of variation

The constant of variation (k) in the inverse relationship equation (y = k/x) can be determined by multiplying the x and y values provided. In this case, k = 250. Therefore, the equation of variation would be y = 250 / x.

Given the inverse relationship where y varies inversely with x, it follows the general equation of y = k/x. This relationship is provided by the constant of variation (k). It can be determined by multiplying the given x and y values.

In this case, x = 2.5 when y = 100. We substitute these into our inverse relationship equation, yielding 100 = k/2.5. By multiplying both sides by 2.5, we are able to find that k = 250. Therefore, the equation of variation would be y = 250/x.

just a quick note, that triangle is misleading some, since the HG side of 6 units, shows longer than GE which is 8, and of course 8 > 6.

Since GE is a perpendicular bisector, that means the angle at G is 90°.

Check the picture below.

To find the length of HE, we utilize the properties of a perpendicular bisector and trigonometry. Knowing that GE halves HF into two equal parts, we calculate HF using trigonometric concepts, then halve it to find HE.

In the question, it's mentioned that GE is a perpendicular bisector of HF. This means that GE bisects HF into two equal lengths. Therefore, the length of HE will be equivalent to half of the length of HF.

Since, HF can be calculated using trigonometry as mentioned. By definition, cose = x/h, so if we know the height 'h' and the angle, we can find 'x' which in this case would be HF, and subsequently HE would be HF/2.

Moreover, in trigonometry, the length of side opposite to the right angle in a right-angled triangle is calculated by the Pythagorean theorem, which states that in a right-angled 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. We use this to find out HF if other two sides are known.

The range of the function y=3/x+8 is all real numbers except 8, since the function approaches 8 but never reaches it due to the vertical asymptote at x=0.

The range of the function y=3/x+8 refers to all possible output values (y-values) that the function can produce. To find the range, it is essential to consider the values that x can take. Since x is in the denominator, x cannot be 0, as division by zero is undefined. Therefore, the function has a vertical asymptote at x=0.

As x approaches both positive and negative infinity, y approaches the constant 8, because the term 3/x approaches 0. Thus, the function can get close to, but never equal, the value of 8. Also, since 3/x can take any value except 0, the range of the function is all real numbers, excluding 8.

The final range of the function y=3/x+8 is therefore: {y | y ≠ 8}, meaning all real numbers that are not equal to 8.

Answer:

The translation is right 4 units and up 4 units

Step-by-step explanation:

we know that

The rule of the translation of the point V to V' is equal to

(x,y) ----> (x+4,y+4)

That means ----> The translation is right 4 units and up 4 units

Verify

V(-2,3) -----> V'(-2+4,3+4)

V(-2,3) -----> V'(2,7)

Is correct

The true statement is: The transformation is a vertical translation. (Statement 3)

Let's analyze each statement:

1. The point moves two units up and four units to the right.

  - This statement is incorrect. The point moves four units up, not two units up.

2. The transformation rule is (x, y) → (x + 0, y + 4).

  - This statement is incorrect. The transformation rule should be (x, y) → (x, y + 4) because the point moves vertically by adding 4 to the y-coordinate.

3. The transformation is a vertical translation.

  - This statement is correct. The point moves vertically, changing only the y-coordinate.

4. The image is four units to the right of the pre-image.

  - This statement is incorrect. The image is at the same x-coordinate as the pre-image (-2), so it's not four units to the right.

5. The translation can be described as (x, y) → (x - 2, y + 7).

  - This statement is incorrect. The translation rule should be (x, y) → (x, y + 4) because the point only moves vertically.

Answer:

Step-by-step explanation:

{z+1}/{z-1} = i.

z+1 = i (z-1)

z+1 =iz -i

z - iz  = -1 -i

z ( 1 -i) = - 1 -i

z = (- 1 - i ) /(1-i) = - (1+i)/(1-i)

z = - (1+i)(1+i)/(1-i)(1+i)

z = - (1+2i +i²)/ ( 1²-i²).........i² = -1

z =-2i/2

z = - i      (one solution)

All the complex numbers z satisfying the equation {z+1}/{z-1} = i is z = -i.

Complex numbers are numbers which are of the form [tex]a + ib[/tex], where a and b are real numbers and i is the imaginary number called iota whose value is [tex]i^2[/tex]= -1.

Given equation is,

(z + 1) / (z - 1) = i

Multiplying both sides by (z - 1),

z + 1 = i (z - 1)

Let z = (a + bi)

Substituting,

(a + bi + 1) = i (a + bi - 1)

(a + bi + 1) - i (a + bi - 1) = 0

a + bi + 1 - (ai + b(i)² - i) = 0

a + bi + 1 - ai - b(i)² + i = 0

Now i² = -1

a + bi + 1 - ai + b + i = 0

Combining the like terms,

(bi - ai + i) + (a + 1 + b) = 0

i (b - a + 1) + (a + b + 1) = 0

Left hand side is a complex number.

A complex number is a + bi = 0, when a = 0 and b = 0.

So, we get,

(b - a + 1) = 0 and (a + b + 1) = 0

b - a = -1 and a + b = -1

So, combining,

a + b = b - a

a + a = b - b

2a = 0

a = 0

Substituting,

b = -1

So the complex number, z = a + bi = -i

Hence the complex number z = -i.

Answer:

Part 1) The price will decrease $5,548

Part 2) The price of the next model is $32,452

Step-by-step explanation:

Let

x ----> the price of the next model

we know that

The current model costs $38,000 -----> represent the 100%

step 1

To find the price decrease in dollars multiply the current model price by 14.6%

14.6%=14.6/100=0.146

so

0.146*($38,000)= $5,548

step 2

Find the price of the next model

To find the price of the next model subtract the price decrease from the price of the current model

so

x=$38,000-$5,548=$32,452

[tex]P=0.4125[/tex]

Step-by-step explanation:

In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).

To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.

The horizontal length between 4.71 and 7.4 is:

[tex]7.4-4.1 = 3.3[/tex].

Then notice that the vertical length in this interval is 0.125.

Then the area of a rectangle is:

[tex]A = lw[/tex]

Where l is the length and w is the width.

In this case we have to:

[tex]l = 3.3[/tex]

[tex]w = 0.125[/tex]

So

[tex]P = A = 3.3 * 0.125[/tex]

[tex]P=0.4125[/tex]

Answer:

a=1, b=-12

Step-by-step explanation:

This is a rational function with a hole at x=3 and a vertical asymptote at x=-4.

The denominator of this rational function must be:

[tex](x - 3)(x + 4)[/tex]

When we expand using the distributive property, we get:

[tex] {x}^{2} + 4x -3 x - 12[/tex]

This simplifies to

[tex] {x}^{2} + x - 12[/tex]

Therefore the graphed rational function is:

[tex]f(x) = \frac{ {x}^{2} - 4x + 3 }{ {x}^{2} + x - 12 } [/tex]

Comparing this to

[tex]f(x) = \frac{ {x}^{2} - 4x + 3 }{ {x}^{2} +a x + b} [/tex]

We have

[tex]a = 1[/tex]

and

[tex]b = - 12[/tex]

Answer:

[tex]y = \frac{1}{2}x+\frac{5}{2}[/tex]

Step-by-step explanation:

The perpendicular bisector of a line passes through the mid-point of the line and the product of slopes of the line and perpendicular bisector will be -1.

So,

[tex]Mid-point\ of\ BC = (\frac{6+8}{2},  \frac{8+4}{2})\\= (\frac{14}{2},  \frac{12}{2})\\= (7,6)[/tex]

The line will pass through (7,6)

Now,

[tex]Slope\ of\ BC = m_1 = \frac{y_2-y_1}{x_2-x_1} \\=\frac{4-8}{8-6}\\= \frac{-4}{2}\\= -2[/tex]

Let

m_2 be the slope of perpendicular bisector

So,

m_1*m_2 = -1

-2 * m_2 = -1

m_2 = -1/-2 = 1/2

The standard equation of line is:

y=mx+b

Where m is slope

So putting the value of slope and point to find the value of b

[tex]6 = \frac{1}{2}*7 +b\\ 6 = \frac{7}{2} + b\\b = 6 - \frac{7}{2}\\ b = \frac{12-7}{2}\\b = \frac{5}{2}\\So,\ the\ equation\ of\ perpendcular\ bisector\ of\ BC\ is:\\y = \frac{1}{2}x+\frac{5}{2}[/tex]

C. positively skewed

Step-by-step explanation:

If a data set has more extremely large data values, the distribution is said to be positively skewed.

Have a great day!

A data set with more extremely large data values is said to be skewed right or positively skewed. This describes a distribution where the tail on the right side is extended due to a few high extreme values.

If a data set has more extremely large data values, the distribution is said to be skewed right or positively skewed. This occurs because the tail of the distribution on the right-hand side is longer or more drawn out compared to the left-hand side.

In a right-skewed distribution, the mean is typically larger than the median, and the mode lies to the left of the median. This asymmetry indicates a larger number of lower values and a few extreme higher values in the data set. For example, if we have a data set with the histogram showing a longer tail on the right, it suggests there are some very large values stretching the scale, resulting in a skewed right distribution.
