PLEASE HELP ME. Select Function or Not A Function.

Answer:

4 rows with 8 students in each

Step-by-step explanation:

4x8=32

The table that represents a function is 1:2, 2:4, 3:6, 4:2.

Option 2 is the correct answer.

Given,

Function table:

1. 1 → 4,  2 → 2, 3 → 4,  2 → 6

2. 1 → 2, 2 → 4, 3 → 6, 4 → 2

3. 2 → 6, 0 → 4, 1 → 6, 2 → 2

4. 2 → 2, 3 → 2, 4 → 6, 3 → 6

We need to find which one is a function.

A function has an input and an output.

We can have different inputs and the same output.

Example:

f(x) = x²

x = 1, -1 are the inputs

f(1) = 1

f(-1) = 1

- We see that we have the same output 1 with different inputs 1 and -1.

i.e Many to one

- But we can not have the same inputs and different outputs.

i.e One to many

- We can have one-to-one in a given function.

We have,

1. 1 → 4,  2 → 2, 3 → 4,  2 → 6

Here,

2 → 2 and  2 → 6 = one to many.

We have the same inputs but different outputs which is not possible.

It is not a function.

2. 1 → 2, 2 → 4, 3 → 6, 4 → 2

Here,

1 → 2 and 4 → 2 =  many to one

2 → 4 and 3 → 6 = one to one

It is a function.

3. 2 → 6, 0 → 4, 1 → 6, 2 → 2

2 → 6 and 2 → 2 = one to many

This is not possible.

It is not a function.

4. 2 → 2, 3 → 2, 4 → 6, 3 → 6

3 → 2 and  3 → 6 = one to many

This is not possible.

It is not a function.

Thus the table that represents a function is 1:2, 2:4, 3:6, 4:2.

Option 2 is the correct answer.

Answer:

12

Step-by-step explanation:

The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.

Using Transitive Property, it is found that b + 3 is equal to 12.

The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.

Given;

If a +5 = b + 3 and a + 5 = 12, then we need to find b +3=

So, a + 5 = 12

and a +5 = b + 3

Then b + 3 is also equal to 12. (Transitive Property )

Therefore, Using Transitive Property, it is found that b + 3 is equal to 12.

Answer:

Katherine will receive $23214 to the nearest dollar from both investments.

Step-by-step explanation:

Simple interest = Principal × Time × rate

Le's work out the interest Katherine earns from the two investments.

Money Market Account

Simple interest = 7770 × 5.8/100 × 6/12

= 7770 × 0.058 × 0.5 =  $225.33

So, the amount she gets at maturity is:

$7770 + $225.33= $7995.33

CD account

Simple interest = 12500 × 0.0725 × 3 = $2718.75

The amount she receives at the end of period is:

$12500 + $2718.75 = $15218.75

The total amount she receives from both investments at maturity is:

$15218.75 + $7995.33 = $23214.08

This to the nearest dollar is:

= $23214

Cost of the trip = $132.69

Step-by-step explanation:

Given:

Total distance = 750 mile

Fixed charge = $20.19

Variable charges = $0.15 per mile

Find:

Cost of the trip

Computation:

Y = $0.15x + $20.19

Y = $0.15(750) + $20.19

Y = $132.69

Cost of the trip = $132.69

Answer:

x is equal to 105

solved!, brainliest pls! would help a lot! ;)

Explanation:

This is easy! Forget about the other numbers only the 75° and the line it's on, only focus on that. Then a straight line is equal to 180° so...

180° - 75° = 105° haha woohoo

Answer:

1+3=4

4+5=9

9+7=16

as we can observe that the we have to add the odd numbers in sequence

16+9=25

25+11=36

Answer:

y - 4= -2(x - 2)

Step-by-step explanation:

(This answer is in point slope form, if you need the answer in a different form like slope intercept, you would have to distribute the negative 2 and bring the negative 4 to the right side.)

So, you know the line is parallel to the equation y= -2x + 10. We know that parallel lines must have the same slope, so the answer will have a slope of negative 2. Because they have given you a point that the line passes through, we are going to put the answer in point slope form. we know a point and we know the slope, hence it is called point-slope.

Point slope form is y - y₁ = m(x - x₁). The m stands for the slope, and the x₁ and y₁ is where you will plug in the x and y coordinates (2,4) .

So to plug in the numbers into point slope form it would be y - 4 = -2 (x - 2). hope this helped :)

Answer:

The answer is below

Step-by-step explanation:

The bottom of a river makes a V-shape that can be modeled with the absolute value function, d(h) = ⅕ ⎜h − 240⎟ − 48, where d is the depth of the river bottom (in feet) and h is the horizontal distance to the left-hand shore (in feet). A ship risks running aground if the bottom of its keel (its lowest point under the water) reaches down to the river bottom. Suppose you are the harbormaster and you want to place buoys where the river bottom is 20 feet below the surface. Complete the absolute value equation to find the horizontal distance from the left shore at which the buoys should be placed

Answer:

To solve the problem, the depth of the water would be equated to the position of the river bottom.

[tex]d(h)=river \ bottom\\\\The \ river \ bottom=-20\ feet(below)\\\\d(h) = -20\\\\\frac{1}{5}|h-240|-48=-20\\ \\\frac{1}{5}|h-240|=-20+48\\\\\frac{1}{5}|h-240|=28\\\\|h-240|=28*5\\\\|h-240|=140\\\\h-240=140\ or\ h-240=-140\\\\h=140+240\ or\ h=-140+240\\\\h=380\ or\ h=100\\\\The\ buoys\ should\ be\ placed\ at\ 100\ feet\ and\ 380\ feet\ from\ left-hand\ shore[/tex]
