Answer:
Step-by-step explanation:
As per definition of the function, every x- value (input) has exactly one corresponding y-value (output)
<u>We can see on the table:</u>
- x = 3.45 and y= 1.72
- x = 3.45 and y = 3.36
Two same input values with different outputs.
So this not a function

1: Jasmine
practices the piano for 30 minutes on Monday. Every day she increases her practice time by 5 minutes. If she continues this
pattern, how many minutes, on the 7th day she will practice Tn = a + (n - 1)d
T7 = 30 + 5(7 - 1) = 30 + 5(6) = 30 + 30
T7 = 60 minutes
Part 2: Anthony
goes to the gym for 10 minutes on Monday. Every day he multiplies his
gym time by 2. If he continues this pattern, on the 5th day she will spend 10(2)^(5 - 1) = 10(2)^4 = 10(16) = 160 minutes in the gym.

Answer 11/20
Step-by-step explanation:
It realistically could be any number based on the person but the most likely answer is 40 hours.
Answer:
4(20+12) / (5-3) = 64
Step-by-step explanation:
The way to solve this problem is simple. Using PEMDAS the obvious thing to do is start with the Parentheses.....
4(20+12) / (5-3)
The way this would look after I use PEMDAS is....
4(32) / (2)
Now there are no exponents so we will now move onto the multiplication section. So we will need to multiply 32 and 4 which will leave us with 128. This now leaves us with...
128/2
Now going on to the last step we will use division since it is our last step we do not need to worry about adding or subtracting. After dividing 128 by 2 it will leave us with the answer of 64. So the answer of the equation is....
4(20+12) / (5-3) = 64
