Is this a function? {(2,2),(-1,5),(5,2),(2,-4)}
Answers
The given set of ordered pairs, {(2,2),(-1,5),(5,2),(2,-4)}, is not a function.
When is a Relation a Function?In a function, we have the domain values which are the set of x-values (input values), and the range values which are the set of y-values (output values). Each x-value of a function can only have one corresponding y-value. This implies that for a relation to be considered a function, no two y-values must be related or correspond to exactly one x-value.
Given, {(2,2),(-1,5),(5,2),(2,-4)}, the x-value, 2, is related to two different y-values, 2 and -4.
Therefore, the given set of ordered pairs is not a function.

Step-by-step explanation:
You invest $2,500 in each of two accounts. Account A earns simple interest at a rate of 2% over 4 years. Account B earns simple interest at a rate of 6% over 18 months. Find the interest earned by each account. How does the interest earned by the two accounts compare? Use paper and pencil. Give an example of two principal amounts and two simple interest rates that would earn equal amounts of interest in one year. Give an example of two principal amounts and two periods of time for which the simple interest earned at 2.42% would be equal
Answers
Answer: See explanation
Step-by-step explanation:
You invest $2,500 in each of two accounts. Account A earns simple interest at a rate of 2% over 4 years.
Interest = PRT / 100
= (2500 × 2 × 4) / 100
= 20000 / 100
= $200
Account B earns simple interest at a rate of 6% over 18 months.
Interest = PRT / 100
= (2500 × 6 × 1.5) / 100
= 22500 / 100
= $225
Interest for account B is more than that of account A at a shorter period of time.
An example of two principal amounts and two simple interest rates that would earn equal amounts of interest in one year will be:
A: Principal = $2000
Interest rate = 3%
Simple interest = (2000 × 3 × 1)/100 = $60
B. Principal = $3000
Interest rate = 2%
Simple interest = (3000 × 2 × 1) / 100
= 6000 / 100
= $60

Answers
Answer:
excuse me friend, for you to get the next pattern, you have to know what has been done from this number to the other number.
so from 3 to 6 it was a + 3 from 6 to 11 it was a+5 from 11 to 18 it was a + 7.
if you look carefully,2,3 and 7 are odd numbers meaning that the next pattern should be an odd number (9) which will be added to the numbers at the top.
you can still say that they were increasing by 2. (3 to 5 to 7)
so you can add 2 to 7 to get a nine. then,add 9 to 18 to get a 27.

Answers
Element and in which every element has a right inverse is a group?
Now, If both the identity and the inverse are of the same side, this is simple. For, instead of the above, say every element has a left inverse. For a∈G denote this left inverse by a−1.
Then(aa−1)(aa−1)=a(a−1a)a−1=aa−1
and we can use the fact that
cc=c
⟹c=1
to get that inverses are in fact two-sided: aa−1=1
From which it follows that
a=1⋅
a=(aa−1)a=a(a−1a)=a⋅

Function transformation involves changing the form of a function.
The equation of the translated function is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
The parent function is given as:
[tex]f(x) = \sqrt[3]{x}[/tex]
First, the function is shifted left by 6 units.
The rule of this translation is:
[tex](x,y) \to (x + 6,y)[/tex]
So, we have:
[tex]f(x) = \sqrt[3]{x + 6}[/tex]
Next, the function is shifted up by 1 unit.
The rule of this translation is:
[tex](x,y) \to (x,y+1)[/tex]
So, we have:
[tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]
Hence, the equation of the translated function is [tex]f(x) = \sqrt[3]{x + 6} + 1[/tex]

Jamie is training for race and runs a 9 minute mile. She has cut a total 39 seconds off her time over the past 6 months. The situation can represented by the expression- 39 divided by 6. On average, how much time she cut off of her mile each month? Find the solution and explain what it means in the context of the problem.
Answers
1) On average, the time Jamie cut off her mile each month is 6.5 seconds.
2) In this context, the 6.5 seconds that Jamie cut off her mile each month means that she can finish a 9-minute-mile race by less than 6.5 seconds.
How is the average cut-off time determined?The average cut-off time per month is determined by the mathematical operation of division.
Average refers to the mean of a data set divided by the number in the data set.
Data and Calculations:The race Jamie is training for = a 9-minute mile
Cut-off time achieved in 6 months = 39 seconds
Period of training = 6 months
Average cut-off time = 6.5 seconds (39/6)
Time Jamie can finish the race = 8 minutes and 53.5 seconds (9 minutes - 6.5 seconds)
Thus, Jamie can complete the race in 8 minutes and 53.5 seconds if she maintains the average.

Answers
Because a few extreme scores can create a deceptively large estimate of variation, the (B) range offers only a crude estimate of the variation in a data set.
What is a range?The range of a set of numbers is the difference between the highest and lowest values. Subtract the smallest number from the largest number in the set to calculate the range. To calculate the range, find the maximum observed value of a variable and subtract the minimum observed value (the minimum). The range only considers these two values and ignores the data points between the distribution's two extremes.Because a few extreme scores can produce an erroneously large estimate of variation, the range provides only a rough estimate of the variation in a data set.Therefore, because a few extreme scores can create a deceptively large estimate of variation, the (B) range offers only a crude estimate of the variation in a data set.

Step-by-step explanation:
To compute (f.g)(5.5) , first compute g(5.5) , then use that value in f(x) to compute the composite function value
g(5.5) = -12(5.5) - 6 = -66 - 6 = -72

f(g(5.5)) = f(-72) = -(-72) + 6 = 72 + 6 = 78
