simplify 3/x-1 + 1/x-2

Answer:

Answer: : g(x)=-sqrt(x+3)+8

Step-by-step explanation:

The function has the same range is the third one:

g(x)=-sqrt(x+3)+8

The range of this function is:

x+3>=0

sqrt(x+3)>=sqrt(0)

sqrt(x+3)>=0

Multiplying the equation by -1:

-1[ sqrt(x+3)>=0]

- sqrt(x+3)<=0

Adding 8 both sides of the equation:

- sqrt(x+3)+8<=0+8

- sqrt(x+3)+8<=8

g(x)<=8

Then Range g(x)= (-Infinite, 8]

Answer: Third option: g(x)=-sqrt(x+3)+8

Answer:

D. 140

Step-by-step explanation:

∠ 1 + ∠ 2 = 180

So:

(3x + 20) + x = 180

4x + 20 = 180

4x = 180 - 20

4x = 160

x = 160 / 4

x = 40

∠ 1 = ∠ 4

∠ 2 = ∠ 3

If ∠ 1 is equal to ∠ 4, just plug in for x and solve.

3x + 20 = 3(40) + 20 = 120 + 20 = 140

Answer:

It's 108

You add the sides 48 and 24 and then subtract it from 180. That how you get your answer.

Answer:

a. -4 + 8p = 68

         8p = 68 + 4 = 72

           p = 72/8 = 9

a. is not the answer as the solution is not 8

b. 4 + 8p = 68

        8p = 68 - 4 = 64

         p = 64/8 = 8

b. is the answer as the solution is 8

c. 4 + -8p = 68

         -8p = 68 - 4 = 64

            p = 64/-8 = -8

c. is not the answer as the solution is not 8

d. 4 + 8p = -68

        8p = -68 -4 = -72

          p = -72/8 = -9

d. is not the answer as the solution is not 8

b. is the answer

Answer:

Normal distributions are symmetric around their mean. The mean, median, and mode of a normal distribution are equal. The area under the normal curve is equal to 1.0. Normal distributions are denser in the center and less dense in the tails.

Step-by-step explanation:

Extra Answered question:

How do you determine if a distribution is normal?

Answer: In order to be considered a normal distribution, a data set (when graphed) must follow a bell-shaped symmetrical curve centered around the mean. It must also adhere to the empirical rule that indicates the percentage of the data set that falls within (plus or minus) 1, 2 and 3 standard deviations of the mean.

I hope this is what your looking for :)

Answer:

I don't the right answers but I know these answers are incorrect:

The sample mean must  equal the population mean.

The standard deviation of the population must be less than 30.

Answer:

7.5 * 10^-4

Step-by-step explanation:

To express this, we will have to multiply 750 by the conversion unit

we have this as;

750 * 10^-6

750 = 7.5 * 10^2

so we have;

7.5 * 10^2 * 10^-6

= 7.5 * 10^(-6+2)

= 7.5 * 10^-4

The diameter of the bacterium in meters using scientific notation is 7.50 × 10^-4

Diameter of the bacterium in scientific notation = 7.50 × 10²

Recall one micrometer = 10^-6

So

7.50 × 10² × 10^-6

= 7.50 × 10^(2-6)

= 7.50 × 10^-4

Answer:

n = 3

Step-by-step explanation:

Given

4n = 2n + 6 ( subtract 2n from both sides )

2n = 6 ( divide both sides by 2 )

n = 3

The solution is, n = 3.

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Answer:

Shaded region is 18.3 units²

Step-by-step explanation:

First find the area of the white triangle.  The base and height of this triangle are both 8.  Thus, the area of the triangle is (1/2)(base)(height), or 32 units.

Next, find the area of the whole circle.  It is πr², which in this case comes

out to π(8 units)² = 64π units².  Realize that (1/4) of this, or 16π units², is the area of the quarter circle that contains the triangle.

To find the shaded area, take the area of the quarter circle (16 π units²) and subtract the area of the triangle (32 units²).

16π units² - 32 units² = 18.3 units²

Shaded region is 18.3 units²

Answer:

x = 14

Step-by-step explanation:

Here's your solution

=> 8x - 22 = 230 - 10x

=> 8x + 10x = 230 + 22

=> 18x = 252

=> x = 252/18

=> x = 14

The quadratic function R that correctly represents the revenue model is given by R(x) = -40x² + 640x.

To find the quadratic function R that represents the revenue, we need to multiply the ticket price x by the number of tickets sold Q(x).

Given that the number of tickets sold Q(x) is given by the linear function Q(x) = -40x + 640, the revenue R can be calculated as:

R(x) = x * Q(x)

Substitute the expression for Q(x) into the revenue equation:

R(x) = x * (-40x + 640)

Now, we'll expand the expression:

R(x) = -40x² + 640x

Thus, the quadratic function R that correctly represents the revenue model is given by R(x) = -40x² + 640x.

Answer:

Obtuse angled triangle

Step-by-step explanation:

If a, b and c are the sides of a triangle with c the largest side

• If a² + b² = c² ⇒ right triangle

• If a² + b² > c² ⇒ acute angled

• If a² + b² < c² ⇒ obtuse angled

Here a = 8, b = 15, c = 23

a² + b² = 8² + 15² = 64 + 225 = 289

c² = 23² = 529

Since a² + b² < c² then obtuse angled triangle

Answer:

pen = 2    book = 3

Step-by-step explanation:

p= pens

b=books

4p +3b =17

5p+2b=16

Multiply the first by 5

Multiply the second by -4

Add both (p variable will ce cancelled)

20p +15b = 85

-20p  -8b = -64

           7b = 21

              b=3        (book =3)

Lets plug this in one of the equations

4p + 3x3 = 17

4p +9 0 19

4p = 8
