Step-by-step explanation:
f(x) = x + 3/ 2
For a
f(2) = 2 + 3 / 2
= ( 4 + 3 ) /2
= 7/2
For b
f(x) = x + 3/2
f^-1(x) = ?
Let y = f(x)
y = x + 3/2
Interchanging the roles of x and y we get,
x = y + 3 / 2
y = x - 3 / 2
Therefore f^-1(x) = x - 3 / 2
For c)
f ^ -1(12) = 12 - 3 / 2
= (24 - 3) / 2
= 21 / 2

why is it important for jews to understand the characteristics of God
Answer:
To conclude, the characteristics of God provide a foundation by which Jews can look up to and mimic behaviour and develop good morals. They can come to understand and appreciate God, particularly as he is unseen, and this allows for them to be able to believe without question e.g. God is all knowing. G-d is all knowing and has a purpose for the world. This gives people faith to believe in God and wait for the Messianic Age to come, and have patience in God’s plan. However, it can be argued that there is no real point in having being taught characteristics of a being which can not be seen. With characteristics, some may argue that the concept of God can still not be understood, and the idea is unclear, particularly as the descriptions are supposedly by God himself, in which many Jews do not believe, as they are culturally and ethnically Jewish, rather than religiously Jewish.
What is the rate of change? I will give u a crown if ur right just help ASAP
Answer:
-2 because rise over run is -2/1 or -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
The rate of change is the slope.
A slope that goes down to the right is negative. This line has a negative slope.
Now we will find the exact value of the slope.
slope = rise/run
rise = vertical distance (up is positive; down is negative)
run = horizontal distance (right is positive; left is negative)
Start at an easy-to-read point. Let's start at (0, 1) which is the y-intercept.
Now we need to go to another easy-to-read point. Let's use (1, -1) as our second point.
(By easy-to-read points, I mean points on grid line intersections whose coordinates can be read easily off the graph.)
We need to go from (0, 1) to (1, -1) by only moving vertically and horizontally. Start at (0, 1). We go vertically down 2 units and then horizontally right 1 unit to get to (1, -1). Going vertically down 2 units is a rise of -2. Going horizontally right 1 unit is a run of +1.
slope = rise/run = -2/1 = -2
slope = -2
The rate of change is the slope.
Answer: rate of change = -2

The six sides of a number cube are labled 1,2,3,4,5,6, . You flip a coin and roll the number cube what is the probability that you land on tails and get a number less than 3.
Answer:
1/6 or 16.67%
Step-by-step explanation:
The probablility for the coin is 50% and the probablility for the cube is 2/6 or 1/3 aka 33.3%. You need to multiply these together to figure out the percentage so 1/2 time 1/3 is 1/6.

Your friend says that the table represents an exponential function because y is multiplied by a constant factor. Is your friend correct? Explain.
A.Yes. Because y is multiplied by a constant factor, the function is exponential.
B.Yes. Because y increases by greater amounts as x increases, the function is exponential.
C.No; Because y is multiplied by a constant factor, the function is not exponential.
D. No; Because x increases by different amounts, the function is not exponential.
x: 0,1,3,6
y: 2,10,50,250
Answer:
C.No; Because y is multiplied by a constant factor, the function is not exponential.
Step-by-step explanation:
For a set of number to be exponential, there is need for it to show a logical increase of a given time frame when the set of number is multiplied by a constant factor. In the table given, though the Y function is multiplied by a constant factor, the increase of the function is irregular so therefore cannot be said to be exponential.

Cody increased the amount of money he saves each week from $40 to $75. By
what percentage did Cody increase the amount of money he saves?
Answer:
So Cody increase his savings by 87.5%
Step-by-step explanation:
We are given Cody's original savings = $40
We are given his new savings total = $75
Now, in order to find out the percentage we have to first find out by how much did he increase his savings:
Increase in savings = $75 - $40 = $35
So now we have the increase in savings we can find out the percentage:
[tex]increase(\%) \: = \frac{increase \: in \: savings}{original \: savings} \times 100[/tex]
Now we plug in our values that we found:
[tex]increase(\%) = \frac{35}{40} \times 100\\ increase(\%) = 87.5\%[/tex]
So Cody increase his savings by 87.5%

What is the mean of the data set?
47, 25, 43, 33
Answer:
The mean is 47
Step-by-step explanation:
First, you want to add up all of the numbers.
47 + 25 + 43 + 33 = 148
Now, you want to divide what you got by how many numbers there are.
148/4 = 37
The mean is 47
Mean of the terms given in the data set as {47, 25, 43, 33} (four terms) will be 37.
Calculations for the mean of a data set: Mean of the terms given in a data set is represented by the avarage of the terms.
Mean = [tex]\frac{\text{Total of the terms in a data set}}{\text{Numbers of the terms}}[/tex]
Total of the terms given in the the data set = 47 + 25 + 43 + 33
= 148
Number of terms in the data set = 4
Substitute these values in the expression of the mean,
Mean = [tex]\frac{148}{4}[/tex]
= 37
Therefore, mean of the data set given in the question is 37.
