In accordance with functional theory, definition of functions and kinds of functions, the function is not injective but surjective. (Correct choice: C)

In accordance with functional theory, functions are relations in which each element of the domain is related to only one element of the range. There are three kinds of functions: (i) Injective - Each domain element is related to one distinct element of the range, (ii) Surjective - There are at least two domain elements that are related to an element of the range, (iii) Bijective - The function is both injective and surjective.

Based on all these information, we conclude that the given function has at least two values of the x-axis (domain) related to one value of the y-axis (range). In a nutshell, the function is not injective but surjective. (Correct choice: C)

Answer:

[tex]10.7933\ \text{m/s}[/tex]

Step-by-step explanation:

d = Distance traveled by sprinter = 200 m

t = Time the sprinter ran for = 18.53 seconds

Average speed is given by

[tex]s=\dfrac{d}{t}[/tex]

[tex]\Rightarrow s=\dfrac{200}{18.53}[/tex]

[tex]\Rightarrow s=10.793308\approx 10.7933\ \text{m/s}[/tex]

The average speed of the sprinter rounded to 4 decimal places is [tex]10.7933\ \text{m/s}[/tex].

Answer:

There were 96 guests at the wedding.

Step-by-step explanation:

Let,

x be the total number of guests at the wedding.

People who chose pasta = 1/3 of the guests = [tex]\frac{1}{3}x[/tex]

People who chose chicken = [tex]\frac{5}{12}x[/tex]

People who chose beef = 24

Now,

[tex]\frac{1}{3}x+\frac{5}{12}x+24=x\\\\\frac{4x+5x+288}{12}=x\\9x+288 = 12x\\288=12x-9x\\288=3x\\3x=288[/tex]

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{288}{3}\\x=96[/tex]

Hence,

There were 96 guests at the wedding.

Answer:

Number of ducks = 37

Number of pigs = 18

Step-by-step explanation:

Let,

x be the number of ducks

y be the number of pigs

According to given statement;

x+y=55     Eqn 1

2x+4y=146     Eqn 2 (As ducks will have 2 legs and pigs will have 4)

Multiplying Eqn 1 by 2

2(x+y=55)

2x+2y=110    Eqn 3

Subtracting Eqn 3 from Eqn 2

(2x+4y)-(2x+2y)=146-110

2x+4y-2x-2y=36

2y=36

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{36}{2}\\y=18[/tex]

Putting y=18 in Eqn 1

x+18=55

x = 55-18

x = 37

Hence,

Number of ducks = 37

Number of pigs = 18

Answer:

34 degrees

Step-by-step explanation:

34 degrees

the angle is 90 degrees

90-56=34

======================================================

Explanation:

Refer to the diagram below. I've added the variable y as the base angles to the isosceles triangle on the left.

Recall that the angles opposite the congruent sides are the base angles. The base angles of any isosceles triangle are the same measure.

Let's solve for y

y+y+56 = 180 .... all angles in a triangle add to 180

2y+56 = 180

2y = 180-56

2y = 124

y = 124/2

y = 62

I've also added the variable z, which is adjacent to one of the y angles.

Since y and z combine to form a straight angle, this means the two angles add to 180

y+z = 180

z = 180-y

z = 180-62

z = 118

Now focus on the isosceles triangle on the right. It has angles x, x, and z = 118.

x+x+z = 180

x+x+118 = 180

2x+118 = 180

2x = 180-118

2x = 62

x = 62/2

x = 31

Answer:

P(-1) = -18

P(5) = 6540

Step-by-step explanation:

Given the polynomial function

P(x) = 9x⁴+9x³-11x²+12x+5

We are to find p(-1) and p(5)

P(-1) = 9(-1)⁴+9(-1)³-11(-1)²+12(-1)+5

P(-1) = 9(1)+9(-1)-11(1)-12+5

P(-1) = 9-9-11-12+5

P(-1) = -23+5

P(-1) = -18

Get p(5)

P(5) = 9(5)⁴+9(5)³-11(5)²+12(5)+5

P(5) = 9(625)+9(125)-11(25)+65

P(5) = 5625+1125-275+65

P(5) = 6540

Answer:

19 cars

13 buses

Step-by-step explanation:

We have a system of equations as follows

X + y = 32 -----1

3x + 27y = 408 ----2

x = car

y = bus

From equation 1

x + y = 32

x = 32 - y ---- 3

We put equation 3 into equation 2

3(32-y) + 27y = 408

96y -3y + 27y = 408

96 + 24y = 408

24y = 408 - 96

24y = 312

Divide through by 24 to get the value of y

Y = 312/24

Y = 13

We put the value of y in equation 3

x = 32 - 13

x = 19

So 19 cars would be needed for the trip and also 13 buses would also be needed
