Answer:

[tex]x = 2, 4[/tex]

Step-by-step explanation:

Given :

[tex]\frac{4-x}{x^{2} -5x+4} + \frac{2}{x-1} =1[/tex]

=============================================================

Factorize the denominator of the first term :

⇒ x² - 5x + 4

⇒ x² - x - 4x + 4

⇒ x(x - 1) - 4(x - 1)

⇒ (x - 4)(x - 1)

============================================================

Hence, the equation now is :

[tex]\frac{4-x}{(x-1)(x-4)} + \frac{2}{x-1} =1[/tex]

============================================================

Multiply the second term by (x - 4) in the numerator and denominator :

[tex]\frac{4-x}{(x-1)(x-4)} + \frac{2(x-4)}{x-1(x-4)} =1[/tex]

============================================================

Combine the numerator of both terms and bring the denominator to the other side :

[tex]\frac{4-x+2(x-4)}{(x-1)(x-4)} = 1[/tex]

[tex]4 - x+2x-8 = x^{2} - 5x + 4[/tex]

[tex]x - 4 = x^{2} - 5x + 4[/tex]

[tex]x^{2} -5x-x+4+4=0[/tex]

[tex]x^{2} -6x+8=0[/tex]

[tex](x-4)(x-2)=0[/tex]

[tex]x = 2, 4[/tex]

Answer:

the triangle is not right-angled

Step-by-step explanation:

First of all, we are told that the perimeter of the triangle is 22 and the two sides are given, 8cm and 5cm respectively. This means that the third side is: 22-(8+5) = 9cm

From this as see that 9cm is the highest length we have and if it were a right-angled triangle, this could be the hypotenuse. Now, to be sure of the initial response we use the Pythagoras theorem. We know that the hypotenuse² = adjacent² + opposite²

let's use the measurements we are given in the question

8²+5²=AC²

64+25=89

AC=√89

AC=9.433981132

AC =9.43cm

and when we add 8+5+9.43 to calculate the perimeter we get 22.43 which is not the initial perimeter, this the triangle isn't right-angled

The amount of money Clint will plan to spend to replace the floors is $17404.09

The hardwood floor is rectangular.

Therefore,

area of hallway = 18 × 6 = 108 ft²

area of the kitchen = 20 × 30 = 600 ft²

area of the living room = 25 × 45 = 1125 ft²

area of each bedroom = 12 × 16 = 192 ft²

area of master bedroom = 14 × 20 = 280 ft²

Hence,

cost of flooring per square foot is $5.48

total cost for flooring = 108(5.48) + 600(5.48) + 1125(5.48) + 192(5.48) + 192(5.48) + 280(5.48) = $13683.56

Cost of installation is $1.49 per square.

total cost of installation = 108(1.49) + 600(1.49) + 1125(1.49) + 192(1.49) + 192(1.49) + 280(1.49) = $3720.53

Total  amount to replace the floor = 13683.56 + 3720.53 = $17404.09

The required sample size is equal to 273.

We have given that,

A political candidate has asked you to conduct a poll to determine what percentage of people support her.

We have to determine the If the candidate only wants an 8% margin of error at a 99% confidence level,

p=0.5 (default since no value is given)

q=1-0.5=0.5

margin of error=5%=0.05

z_c=1.65 at 90% confidence.

The margin of error:

[tex]e= sqrt(p(1-p)/n)*z_c[/tex]

Use the given value in the above formula we get,

0.05=sqrt(0.5*0.5/n)*1.65

n= (0.5*1.65/0.05)^2=272.25

Therefore, The required sample size is equal to 273.

Answer:

Yes, they are equivalent

Step-by-step explanation:

18 = 3x - 6 + x

+6 +6

24 = 3x + x

24 = 4x

24/4 = 4x/4

6 = x

18 = 4x - 6

+6 +6

24 = 4x

24/4 = 4x/4

6 = x

Both equations are equal to x = 6, therefore they are equivalent

Answer:

Yes

Step-by-step explanation:

18 = 3x - 6 + x

x = 1x

Combine like terms

3x + 1x = 4x

18 = 4x - 6 and 18 = 4x - 6

They are equivalent.

The surface area of the cylinder is 1155.52 square ft if the radius and height of the cylinder are 8 ft and 15 ft.

In geometry, it is defined as the three-dimensional shape having two circular shapes at a distance called the height of the cylinder.

We know the volume of the cylinder is given by:

[tex]\rm V = \pi r^2 h[/tex]

The surface area of the cylinder:

[tex]\rm A =2\pi rh+2\pi r^2[/tex]

r = 8 ft

h = 15 ft

[tex]\rm A =2\pi (8)(15)+2\pi (8)^2[/tex]

A = 1155.52 square ft

Thus, the surface area of the cylinder is 1155.52 square ft if the radius and height of the cylinder are 8 ft and 15 ft.

Step-by-step explanation:

We will start by finding how much money she made before spending it. The amount of money she took home added to how much money she spent will give us this. ([tex]12 + 36 = 48[/tex]). This means she made $48 before spending it.

Now we can solve for her wage. Let [tex]x[/tex] be her hourly wage

(the 6 is the number of hours she worked, this multiplied by her wage should give us 48)

[tex]6x = 48\\x = 8[/tex]

The remainder of (h4 h2 – 2) ÷ (h 3). The remainder is 88.

Given:

(h⁴ + h² – 2) ÷ (h + 3)

Using reminder theorem

First step is to equate:

h + 3 =0

h = - 3

Second step is to determine the remainder

Substitute h = - 3 into (h⁴ + h² – 2)

Hence:

h⁴ + h² – 2 = (-3)⁴ + (-3)² - 2

h⁴ + h² – 2= 81 + 9 - 2

h⁴ + h² – 2=90-2

h⁴ + h² – 2= 88 remainder

The area of the triangle AOB is 9√3 square units

The triangle AOB is an equilateral triangle with the following parameters:

Side length, x = 6

Angle, y = 60

The area of the triangle is then calculated using:

So, we have:

Area = 0.5 * 6^2 * sin(60)

Evaluate

Area = 18 * 0.5√3

Evaluate the product

Calculate the first differences between the y-values:

[tex]\sf 3 \underset{+1}{\longrightarrow} 4 \underset{+3}{\longrightarrow} 7 \underset{+5}{\longrightarrow} 12 \underset{+7}{\longrightarrow} 19[/tex]

As the first differences are not the same, we need to calculate the second differences:

[tex]\sf 1 \underset{+2}{\longrightarrow} 3 \underset{+2}{\longrightarrow} 5 \underset{+2}{\longrightarrow} 7[/tex]

As the second differences are the same, the relationship between the variable is quadratic and will contain an [tex]x^2[/tex]  term.

--------------------------------------------------------------------------------------------------

To determine the quadratic equation

The coefficient of [tex]x^2[/tex]  is always half of the second difference.

As the second difference is 2, and half of 2 is 1, the coefficient of [tex]x^2[/tex] is 1.

The standard form of a quadratic equation is:  [tex]y=ax^2+bx+c[/tex]

(where a, b and c are constants to be found).

We have already determined that the coefficient of [tex]x^2[/tex] is 1.

Therefore, a = 1

From the given table, when [tex]x=0[/tex], [tex]y=12[/tex].

[tex]\implies a(0)^2+b(0)+c=12[/tex]

[tex]\implies c=12[/tex]

Finally, to find b, substitute the found values of a and c into the equation, then substitute one of the ordered pairs from the given table:

[tex]\begin{aligned}\implies x^2+bx+12 & = y\\ \textsf{at }(1,19) \implies (1)^2+b(1)+12 & = 19\\ 1+b+12 & = 19\\b+13 & =19\\b&=6\end{aligned}[/tex]

Therefore, the quadratic equation for the given ordered pairs is:

[tex]y=x^2+6x+12[/tex]

Multiplication is the process of multiplying. The products that have the same sign as the product of -2 3/7 and -6/11 are B and D.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The product of two positive numbers and the product of two negative numbers both are positive while the product of a negative number and a positive number is negative. Therefore, the product of -2 3/7 and -6/11 is positive, since both are negative.

A.) 3/8 × (-6/7) = Negative

B.) 1 2/9 × 2 6/17 = Positive

C.) -9/20 × 3 4/5 = Negative
