Step-by-step explanation:

Step-by-step explanation:

step 1. f(0) = 0/(0^2 + 1) = 0/1 = 0

step 2. -f(x) = -x/(x^2 + 1)

step 3. f(9) = 9/(9^2 + 1) = 9/82.

A function is defined as a relation between a set of inputs having one output each. The values can be written as shown below.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given function is f(x) = [tex]\frac{x}{x^{2} +1}[/tex], therefore, the values can be found by as shown below. Therefore, we can write,

(a) f(0) = 0/0+1 = 0

(e) – f(x) = - [ x / (x²+1)]

(b) f(9) = 9/(81 + 1) = 9/82

(f) f(x + 1) = (x + 1)/(x² + 2x + 2)

(c) f(-9) = - 9/(81 + 1 ) = -9/82

(g) f(3x) = 3x/(9x² + 1)

(d) f(-x) = -x/(x² + 1)

(h) f(x + h) = (x + h) / [(x+h)²+1]

Step-by-step explanation:

Given that:

H0 : μ = 1

H1 : μ > 1

Sample size, n = 20 ; xbar = 1.05; Standard deviation, s = 0.13

Test statistic;

t because sample size is < 30

(xbar - μ) ÷ (s/sqrt(n))

(1.05 - 1) ÷ (0.13 / sqrt(20))

0.05 ÷ 0.0290688

Using a p value calculator :

With alpha = 0.05 ; df = n - 1 = 20 - 1 = 19

Answer:

A) length = 9cm, width = 4 cm

Step-by-step explanation:

The key word "times" refers to multiplication, so if you're trying to find dimensions at 1/4 times its original size, you need to multiply the original dimensions by 1/4.

l = 36

new l = 36 (1/4)

          = 36/4

          = 9 cm

w = 16

new w = 16 (1/4)

            = 16/4

            = 4 cm

Explanation:

Label the center point of the circle as point G.

Also, label the top and bottom tangent points as H and J respectively. This means that H is on line segment ED, while J is on line segment EF.

The given arc measure of 100 degrees directly leads to the central angle HGJ to be 100 degrees.

Focus on quadrilateral EHGJ. It has two right angles at points H and J since they are tangent points. Angle G of this quadrilateral was found to be 100. Let's find angle E

E+H+G+J = 360 ..... any four angles of a quadrilateral add to 360

E+90+100+90 = 360

E+280 = 360

E = 360-280

E = 80

Or as a shortcut, we can note that angles E and G must add to 180, since H+J = 90+90 = 180, making up half of 360.

So, E+G = 180 leads to E+100 = 180 which solves to E = 80.

Once we know that E = 80, this leads to angle DEF to be 80 degrees.

This is an inscribed angle that subtends arc DF. By the inscribed angle theorem, we double the inscribed angle value to get the arc measure

arc DF = 2*(inscribed angle DEF)

arc DF = 2*(80)

arc DF = 160 degrees

Answer:

The solution has infinitely many solutions.

Step-by-step explanation:

Correct option is - The solution has infinitely many solutions.

The expression is of the form -

ax + b = ax + b

In the expression , any value of x will satisfy

So, we get infinitely many solution

For example -

for x = 1

a(1) + b = a(1) + b

⇒ a + b = a + b

satisfied.

for x = 2

a(2) + b = a(2) + b

⇒ 2a + b = 2a + b

satisfied.

Hereon, for any value of x , it satisfies.

Answer:

0.7 ; 0.65 ; 0.115

Step-by-step explanation:

Step-by-step explanation:

P(A) = 0.5 ; P(B) = 0.3

P(not successful) = P(B') = 1 - 0.3 = 0.7 ; P(A') = 1 - 0.5 = 0.5

1.)

Both events are independent events, hence the outcome of one does not depend on the other. That is the failure of the Asian project has nothing to do with the European project.

Probability that European project isn't successful;

P(B') = 1 - P(B) = 1 - 0.3 = 0.7

2.)

Probability that atleast one of the 2 projects is successful :

P(AUB) = P(A) + P(B) - P(AnB)

P(AnB) = P(A) * P(B) = 0.5 * 0.3 = 0.15

P(AUB) = 0.5 + 0.3 - 0.15 = 0.65

3.)

Probability that only the Asian project is successful, given that atleast one of the two projects is successful :

[P(A) - P(AnB)] ÷ P(AuB)

[0.5 * 0.15] ÷ 0.65

= 0.075 ÷ 0.65

= 0.1153846

= 0.115

The measure of arc ILR is 223 degrees

The sum of angle on a straight line is 180 degrees

Given the following parameter

∠ICR = (3x + 5)°, and

∠RCL = (x – 1)°.

Taking the sum:

3x + 5 + x - 1 = 180

4x + 4 = 180

4x = 176

x = 176/4

x = 44

arc ILR = 180 + arcRL
arc ILR = 180 + 44 - 1

arc ILR = 223 degrees

Hence the measure of arc ILR is 223 degrees

Answer:

Step-by-step explanation:

In order to determine the value of x, the measure of angle BCA must be known. If we assume the figure is a kite, then ...

  ∠CDB = ∠CBD = 61°

  ∠CBD +∠BCA = 90°

So, the measure of angle BCA is ...

  ∠BCA = 90° -∠CBD = 90° -61°

  ∠BCA = 29°

__

Now we can find x from ...

  29° = (-6 +x)°

  29 +6 = x = 35

Answer:

A

Step-by-step explanation:

Given:

The equation of a line is

[tex]y=x-4[/tex]

To find:

The slope and y-intercept of the line.

Solution:

We have,

[tex]y=x-4[/tex]          ...(i)

The slope intercept form of a line is

[tex]y=mx+b[/tex]            ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

[tex]m=1,b=-4[/tex]

Slope of the line = 1

y-intercept of the line = -4

The coordinate form of y-intercept is (0,b). So, the y-intercept of the given line is (0,-4).

Therefore, the slope of the line is 1 and the y-intercept is (0,-4).
