The angle would be the tangent.

Tangent ( angle) = opposite leg/ adjacent leg

Tangent angle = 28.4/100

Angle = tan^-1(28.4/100)

Answer:

The factorized form of 2x + 8 is 2(x+4).

Step-by-step explanation:

Given the expression

Let us factorize the expression

2x + 8

Rewrite 8 as 2·4

[tex]2x\:+\:8=2x+2\cdot \:\:4[/tex]

Factor out common term 2

           = 2(x+4)

Therefore, factorized form of 2x + 8 is 2(x+4).

Answer:

The population mean (μ) = 26.

Step-by-step explanation:

a) Data and Calculations:

The population characteristics = 20 and 36

Total population of interest = 56 (20 + 36)

Number of groups in the population = 2

Therefore, the population mean (μ) = 56/2 = 28

b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest.  The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.

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

Concept: Arithmetic Sequence & Series

The solution is, the correct formula for the following Arithmetic Sequence:  -4, -1, 2, 5, 8,…, is, an = -4 + 3(n – 1), the value of the n-th term.

We know that,

from Arithmetic Sequence & Series we get,

The nth term of AP : a_n = a + (n – 1) × d

where, a = first term

d = common difference,

Notice the change is +3 for the first iteration and then +3 for the second iteration and so on

i.e. here,

a = -4

d = +3

Hence it must work for any nth variable.

So we have -4+3(n-1)

Hence, we get, an = -4 + 3(n – 1).

Step-by-step explanation:

[tex]We\ are\ given\ that,\\A\ is\ the\ set\ of\ squares.\\x\ belongs\ to\ the\ Set\ A\\y\ belongs\ to\ the\ Set\ A,\ too.\\Hence,\\Lets\ consider\ that\ \sqrt{x} =a, \sqrt{y}=b\\Hence,\\a^2=x, b^2=y\\Before\ proceeding\ we\ may\ use\ the\ following\ Laws\ Of\ Exponents:\\* For\ any\ two\ real\ numbers,\ m\ and\ n, m^a*n^a=(mn)^a\\* For\ any\ two\ real\ numbers,\ m\ and\ n, \frac{m^a}{n^a}=[\frac{m}{n}]^a\\[/tex]

[tex]Now,\\When\ we\ intend\ to\ multiply\ x\ and\ y,\\x*y=a^2*b^2\\xy=a^2*b^2\\xy=(ab)^2\\As\ the\ new\ term\ xy\ is\ the\ square\ of\ product\ of\ a\ and\ b\,\ it\\ is\ a\ square\ too.\ Hence,\ it\ belongs\ in\ the\ set\ of\ squares(A).\\Similarly,\\When\ we\ intend\ to\ divide\ x\ by\ y,\\\frac{x}{y} =\frac{a^2}{b^2}\\Hence,\\\frac{x}{y} =[\frac{a}{b}]^2\\As\ the\ new\ term\ \frac{x}{y}\ is\ the\ square\ of\ the\ quotient\ of\ a\ and\ b\ i.e\ \frac{a}{b}, the\ term\\ \frac{x}{y}\ too\ belongs\ toA[/tex]

Answer:

The answers are:

Step-by-step explanation:

Given:

Distance of Hotel and car = 163 miles

Distance travelled by car per liter = 10.5 miles

The number of liters will be obtained by dividing the total distance by distance travelled in one liter.

So,

[tex]number\ of\ liters = \frac{163}{10.5} = 15.523\ liters[/tex]

2. Cost for petrol:

Cost of petrol per liter = 138.9 pence per liter

Then the total cost of petrol will be:

[tex]Total\ cost = 138.9*15.523 = 2156.1447 => 2156.2\ pences[/tex]

3. Time taken for journey

Distance travelled in an hour = speed = 50 miles per hour.

The speed is given by the formula:

[tex]speed = \frac{distance}{time}[/tex]

Putting the values

[tex]50 = \frac{163}{t}\\t = \frac{163}{50}\\t = 3.26\ hours[/tex]

It will take: 3 hours and 0.26*60 = 15.6 minutes => 3 hours 16 minutes

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
