Given the following functions f(x) and g(x), solve (f + g)(3) and select the correct answer below:f(x) = 2x + 21

g(x) = x − 24

Answers

Answer:

Let f(x) and g(x) be the function then;

(f+g)(x) = f(x)+g(x)

Given the functions:

f(x) = 2x+21

g(x) = x-24

Solve for : (f+g)(3)

(f+g)(3) = f(3)+g(3)           .....[1]

Put x = 3 in f(x) and g(x) we have;

f(3) = 2(3)+21 = 6+21 = 27

and

g(3) = 3-24 = -21

Substitute these values in [1] we have;

(f+g)(3) =27 +(-21) = 27-21 = 6  

Therefore, the value of (f+g)(3)  is 6
(f+g)(x) = 2x+21 +x-24= 3x -3now put x=3 in order to find (f+g)(3)(f+g)(3) = 3(3) -3= 9-3= 6, i hope this helps 

To the nearest tenth, what is the length of the hypotenuse of an isosceles right triangle with a leg of 7 3 inches? A) 15.7inches
B) 16.2 inches
C) 17.1 inches
D) 18.5 inches

Answers

Answer:

the answer is the option C

17.1\ in

Step-by-step explanation:

we know that

An isosceles right triangle has two equal legs

Let

x------> the length side of the hypotenuse

y-----> the length side of the leg

Applying the Pythagoras theorem

x^(2) =y^(2)+y^(2)

x^(2) =2y^(2)

In this problem we have

y=7√(3)\ in

Substitute and solve for x

x^(2) =2(7√(3))^(2)

x=17.1\ in

What is the difference between a linear function and a nonlinear function? Explain what each looks like when represented as a table and as a graph.

Answers

The difference between the linear and nonlinear functions are their degrees. For linear functions, the highest order is only 1 while more than for those nonlinear functions. If these are presented in graphs, linear functions would generate straight lines while parabola or other curved lines will be generated for nonlinear functions. 

The correct answer is:

A linear function has a constant rate of change, while a non-linear function does not have a constant rate of change.

Explanation:

As the name implies, a linear function will graph as a straight line. Since it is a straight line, this means that the distance between any two consecutive points must be the same; it must go up or down the same amount between each pair of points, or it will not form a straight line.

This means that a table of a linear function will have consecutive values that either increase or decrease by the same amount.

A non-linear function, on the other hand, will not have these things. It will not graph as a straight line, and each pair of consecutive points will not increase or decrease by the same amount. Instead, they will increase or decrease by different amounts.

A certain book is for sale in both Belize and Brazil. In Belize, it sells for 80.39 Belize dollars. In Brazil, it sells for 63.65 Brazilian reals. The exchange rate of US dollars to Belize dollars is 1:1.9246, and the exchange rate of US dollars to Brazilian reals is 1:1.7880. When converted into US dollars, which country sells the book at a more expensive price, and how much more expensive is it? Round all currency values to two decimal places.

Answers

A book is sold in Belize for 80.39 Belize dollars.
In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of US Dollars to Belize Dollars is 1:1.9246
The exchange rate of US Dollars to Brazilian Real is 1:1.7880

If we convert the two into dollars,
Belize Dollars 
1 : 1.9246 = X : 80.39 
1.9246X = 80.39
X = $ 41.77 

Brazilian Real
1 : 1.7880 = X : 63.65  
1.7880X = 63.65 
X = $ 35.60

Difference = $ 41.77 - $ 35.60
Difference = $ 6.17

So, in Belize the book is more expensive by $ 6.17

Answer:

6.17

Step-by-step explanation:

Belize Dollars

1 : 1.9246 = X : 80.39

1.9246X = 80.39

X = $ 41.77

Brazilian Real

1 : 1.7880 = X : 63.65  

1.7880X = 63.65

X = $ 35.60

Difference = $ 41.77 - $ 35.60

Difference = $ 6.17
