Let f(x) = 4x + 3 and g(x) = -2x + 5. Find.(f.g)(5)
a. 23
b. -17
c. -41
d. -5

Answers

Answer:

After solving we get (f.g)(5)=-115

But the correct option is not given in the question.

Step-by-step explanation:

We are given:

[tex]f(x) = 4x+3\\g(x)=-2x+5[/tex]

We need to find (f.g)(5)

First we will multiply f and g to find (f.g) i.e

[tex](f.g)(x)= f(x) \times g(x)\\(f.g)(x) = (4x + 3)(-2x + 5)\\(f.g)(x)=4x(-2x+5)+3(-2x+5)\\(f.g)(x)=-8x^2+20x-6x+15\\(f.g)(x)=-8x^2+14x+15\\[/tex]

Now putting x=5

[tex](f.g)(x)=-8x^2+14x+15\\Put \ x=5\\(f.g)(5)=-8(5)^2+14(5)+15\\(f.g)(5)=-8(25)+70+15\\(f.g)(5)=-200+70+15\\(f.g)(5)=-115[/tex]

So, after solving we get (f.g)(5)=-115

But the correct option is not given in the question.

3. Sum of digits of a two digit number is 14. When 18 is added to the original number, then the new number is obtained by exchanging the digits of the original number. Express the statements in equation.​

Answers

Answer:

let the numbers be xy

general form of the number =10x+y

sum of digits of a number =14

x+y=14………[1]

if 18 is added to the number, then digits are interchanged

10x+y+18=10y +x

9x-9y=-18

X-y=-2………[2]

the linear equations are 1) x+y=14

2) X-y=-2

adding [1],[2]

2x=12

x=6

x+y=14

y=14-x

y=14-6

y=8

there fore the number =10*6+8

=68

check:-

1)6+8=14

2)68+18=86

Answers

Answer:

1) Not a function 2) function 3) function

Step-by-step explanation:

Use the vertical line test. If you draw a line on every vertical line on the graph and you see two points, it is not a function.

The graph is shown in options B) and C) represents a function and this can be determined by carefully observing the given graph.

Check all the options in order to determine whether the graph represents a function or not.

A) The graph shows in this option that the two lines are intersecting at (x = 2). Therefore, this graph does not represent a function.

B) The graph shows in this option is in the shape of a parabola whose vertex is at  (-2,0). Therefore, this graph does represent a function.

C) The graph shows in this option is in the shape of a wave. This graph may represent a trigonometric function. Therefore, this graph does represent a function.

restricted lifestyle

Step-by-step explanation:

on ed

The option that is not an advantage of renting is;

D: Restricted lifestyle

When we rent a home, it means that we are paying the owner of the home some money periodically which could be yearly, monthly weekly e.t.c to make use the house.

Now, renting a home could be advantageous for different reasons and so let us look at each option given;

A) Ease of mobility; Sometimes we need to rent a home close to our place of work or business for ease of movement and as such this is an advantage.

B) Fewer responsibilities; Sometimes when we don't have too many responsibilities, renting a small home for a specific purpose could be very beneficial.

C) Lower Initial Costs; Renting a home is always cheaper initially than buying a home.

D) Restricted lifestyle; This is not an advantage of renting a home because renting a home is not meant to restrict your lifestyle but improve it.

Which of the following statements are true for this function? Select all that apply.
A. The function is discontinuous at x=-1
B.The function is discontinuous at x=1
C. The value of the function is never negative
D. x=1 is not the domain of the function
E. The value of the function at x=-1 is 0
F. The value of the function at x=1 is 0

Answers

Answer:

A, C, and E

Step-by-step explanation:

Given is a graph of   a function first a straight line, followed by a semi circle centred at the origin and another piece of straight line not connected to the other graph.

We can see that the funciton is discontinuous at x=1 since

right limit = 1 and left limit =0

x=1 is in the domain .

f(-1) =0 is right

But f(1) =0 is incorrect

Thus correct options are

The function is discontinuous at x = 1.

The value of the function is never negative.

The value of the function at x = -1 is 0

Captain America's circular shield has a diameter of 76.2 centimetres. What is the area of his shield?​

Answers

Answer:

4560.37

Step-by-step explanation:

A= 1 /4 x π x 76.2²

Brainliest?????

The area of the Captain America's circular shield is 4560.36 cm²

From the question,

We are to determine the area of Captain America's circular shield, which has a diameter of 76.2 cm.

To do this,

We will use the formula for finding the area of a circle.

The formula for the finding the area of a circle is

[tex]A = \pi r^{2}[/tex]

Where, A is the area

and r is the radius of the circle

From the question

Diameter of the circular shield = 76.2 cm

First, we will determine the radius of the circular shield

From

[tex]Radius = \frac{Diameter}{2}[/tex]

∴ Radius of the circular shield = [tex]\frac{76.2}{2}[/tex] cm

Radius of the circular shield = 38.1 cm

Now, for the area of the shield

r = 38.1cm

∴ Area of the shield = [tex]\pi \times 38.1^{2}[/tex]

Area of the shield = 1451.61π

(Take π = 3.14159)

∴ Area of the shield = 1451.61 × 3.14159

Area of the shield = 4560.36 cm²

Hence, the area of the circular shield is 4560.36 cm²
