Which is the graph of arctan(x)?

Answer:

4/5

Step-by-step explanation:

Given that:

Number of options = a, b, c, d, e

Number of correct answer choice = 1

Therefore, number of wrong answers = 4

Recall :

Probability = (number required outcome / number of total possible outcomes)

P(wrong answer) :

Number of Required outcome = number of wrong answer choices = 4

Total answers = 5

Hence,

P(wrong answer) = 4 / 5 = 0.8

Answer:

30

Step-by-step explanation:

First: f(3)=2(3) is 3F=6, divide by 3 on each side and F=2.

Second g(3)=5(3) is 3G=15, divide by 3 on each side and G=5.

Finally, f(g)(x) is (2)(5)(3) = 10x3 = 30.

The value of the function f ( g ( x ) ) when x = 3 is 30

What is Composition of functions?

Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that
h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.

Given data ,

Let the first function be f (x ) = 2x

Let the second function g ( x ) = 5x

Now ,

The composite function is of the form f ( g ( x ) ) ,

So assign the value of x in f ( x ) as x = g ( x )

And , g ( x ) = 5x

So , the composite function will be

f ( 5x ) = 2 ( 5x )

          = 10x

Now , when x = 3

f ( g ( 3 ) ) = 10 x 3

               = 30

Therefore , the value of f ( g ( 3 ) ) is 30

Hence , the value of the function f ( g ( x ) ) when x = 3 is 30

Answer:

78

Step-by-step explanation:

x+(x+2)+(x+4)=228

x+x+2+x+4=228

3x+6=228

Subtract 6 from both sides

3x=228-6

3x=222

Divide both sides by 3

x=74.The first number is 74

The second number (x+2)=74+2=76

Answer:

3y - 4x + 7 = 0

Step-by-step explanation

The equation of the line l in point slope form is expressed as;

y-y0 = m(x-x0)

Get the slope m of the known line

Given the line 3x+4y=8

4y = -3x+8

y = -3x/4 + 2

m = -3/4

The slope of the line m = -1/(-3/4) = 4/3

Substitute m = 4/3 and the point (2,-5) into the expression above;

y - (-5) = 4/3(x-2)

y+5 = 4/3 x + 8/3

Multiply through by 3;

3y + 15 = 4x + 8

3y-4x + 15 - 8 = 0

3y - 4x + 7 = 0

Hence the equation that can be used to find the equation of line m is 3y - 4x + 7 = 0

Equation that can be used to find the equation of line m is

[tex]y+5=\frac{-3}{4} (x-2)[/tex]

Given :

Lines l and M are parallel. Line l can be represented by the equation 3x+4y=8

Line m passes through the point (2, -5)

Equation of line L is [tex]3x+4y=8[/tex]

Lets find out the slope of the given equation by writing it in y=mx+b form

where m is the slope

[tex]3x+4y=8\\4y=-3x+8\\y=\frac{-3}{4}x +2[/tex]

the slope of line L is [tex]\frac{-3}{4}[/tex]

Slope of parallel lines are equal

slope of parallel line M is also [tex]\frac{-3}{4}[/tex]

Line M passes through (2,-5)

We use point slope formula to find equation of line m

[tex]y-y_1=m(x-x_1)\\y+5=\frac{-3}{4} (x-2)\\[/tex]

Multiply both sides by 4

[tex]4(y+5)=-3 (x-2)\\4y+20=-3x+6\\3x+4y+20=6\\3x+4y=14[/tex]

equation can be used to find the equation of line  is

[tex]y+5=\frac{-3}{4} (x-2)[/tex]

Answer: x=4

Step-by-step explanation:

We know that line segment AC= AB + BC

we also know that AB= 3x+8 and BC= 2x-5

by substituting these, we get AC= (3x+8)+(2x-5)

AC is given as being 23, so we know that

23= (3x+8)+(2x-5)

by combining like terms, we get that

5x+3=23

simplify this to get that x=4

Answer:

Colour of coat

Step-by-step explanation:

We are told that the veterinarian wants to determine if a supplement with both glucosamine and chondroitin would be more beneficial than glucosamine alone for dogs’ joint health.

In randomized block design, blocking is the arrangement of experimental units in groups known as blocks which are similar to one another.

Looking at the options given, by blocking on size, age or dog breed, the source of variability which led to the inconclusiveness initially would be controlled which then leads to a greater accuracy in result. Since there can be big, medium and small size of dog: there can be older or younger dogs: there can be different type of dog breeds as well. All these can likely affect the results of the experiment.

Whereas, blocking on colour of coat is not an appropriate variable because it has no effect on the experiment.

Answer:

Step-by-step explanation:

to find the answer you need to multiply both numerators together and put that over the product of the denominators, this is going to leave you with a fraction smaller than the original fractions. that is normal, because you are multiplying terms smaller than one together. same applies to decimals less than one
