Is The Relation A Function?

Answers

Answer 1

Answer:

Yes, each x-value is paired with exactly one y-value (no more than that)

Domain: x = -2, x = 1, x = 4, x = 7

Range: y = -3, y = 5, y = 6

No, the inverse is not a function, the x value of 6 would be paired with two y values (-2 and 7)

1) Area of garden = side * side

                             = 10* 10

                             = 100 Sq.m

2) Area of each flowerbed = 1*1 = 1 sqm

3)  Area of 4 flowerbed = 1 * 4 = 4 sqm

 Area of the remaining garden = Area of garden - area of 4 flower bed

                                                    = 100 - 4

                                                    = 96 sq.m

4) Length of the fence = 4 *side

                                      = 4 * 10 = 40 m

5)  Cost of planting in the remaining garden = 96 * 20

Which number is the same distance away from zero as is the number 4?

Answers

Answer:

Step-by-step explanation:

hopw this helps

Answer: That would be called absolute value (how far a number is from zero) so that means that it could be any number as long as the negative AND POSITIVE version of the number has lines on each side of it. In this case since you're using 4( which is positive) the answer would be -4( which is negative).  

Shannon rolled a number cube 50 times. A "4" appeared 15 times. Find the ratio of the number of times four appeared to the total number of rolls.

Answers

Answer:

3 : 10

Step-by-step explanation:

Given that :

Total number of rolls = 50

Nunber of times '4' appeared = 15

Expressing the Number of times 4 appeared and the total number of rolls as a ratio:

Number of times 4 appear : total number of rolls

15 : 50

We reduce the the lowest term :

Divide both sides by 5

3 : 10

1.8y-9.3y-6.3y I don't get it

Answers

Answer:

-13.8y

Step-by-step explanation:

Since these all have the same variable you don't need to worry that much. Let's take away the y to make it easier. Now you just subtract normally.

1.8 - 9.3

A trick that I use is that I subtract 9.3 - 1.8, and then add a negative sign. So that is -7.5

Then, subtract -7.5-6.3. You add these because they have the same symbol. So it is -13.8

We can't forget about the variable!! So it is -13.8y

Hope this helps!!

There are 101 Year 13 pupils in a tennis club, out of a total of 146 pupils. Write this proportion as a percentage. Give your answer correct to 1 decimal place when appropriate.

Answers

Answer: 69.2%

Step-by-step explanation:

There are 101 Year 13 students out of a total number of 146 pupils.

To find this as a percentage, divide the total number of students by the year 13 students and then multiply by 100%:

= Year 13 students/ Total students * 100%

= 101 / 146 * 100%

= 0.692 * 100%

= 69.2%

a) $1.80 for a 6 pack
b) $6.00 for a 24 pack
c) $4.80 for a 12 pack
d) $10.00 for a 36 pack

Answers

Answer:

D) 10.00 for a 36 pack

Step-by-step explanation:

(I'm going up by the smallest pack to the highest because I noticed they are all multiples of 6)

1.80 for a 6 pack (double it to become a 12 pack)

3.60 for a 12 pack but the other 12 pack is more expensive making a 6 pack cheaper. (add another 6 pack)

5.40 for a 18 pack (add another 6pack)

7.20 for a 24 pack so this means the 6pack is more expensive and a 24pack is cheaper (in gonna keep adding till we get to 36 pack)

9 for a 30 pack

10.80 for a 36 pack

Write the sum using summation notation, assuming the suggested pattern continues. -3+6+15+24+...+132

Answers

Answer:

Option (4)

Step-by-step explanation:

Given sequence is,

-3 + 6 + 15 + 24 + ........+ 132

Difference in 1st and 2nd term = 6 - (-3)

                                                   = 9

Difference in 2nd and 3rd term = 15 - 6

                                                    = 9

There is a common difference of 9 in each successive term.

Therefore, it's an arithmetic sequence.

Let the nth term of this sequence is (a + bn).

For the first term → n = 0,

a = -3

For second term → n = 1

-3 + b(1) = 6

b = 6 + 3

b = 9

Therefore, nth term of the sequence will be,

[tex]T_n[/tex] = -3 + 9n

For nth term = 132

-3 + 9n = 132

9n = 135

n = [tex]\frac{135}{9}[/tex]

n = 15

Sum of 15 terms can be represented by the expression;

[tex]\sum_{n=0}^{15}(-3+9n)[/tex]

Option (4) is the answer.
