Answer:
Step-by-step explanation:
Step 1: Write out limit
Step 2: Evaluate
(2 + 1)(3(2)² - 9)
3(3(4) - 9)
3(12 - 9)
3(3)
9
To solve this problem, we have to figure out a rule for the function. We are told that it is a two-step rule, so it is most likely the input multiplied by a coefficient plus a constant. Let’s let the input be represented by the variable x and the output be represented by the variable y. Using our knowledge, we can see that the outputs are close to triple the input, so we set up the preliminary equation:
y = 3x + b,
where b is a constant. If we want to solve for b, we must plug in one of our input/output pairs. If we plug in (5,16), we get the following:
16 = 3(5) + b
16 = 15 + b
1 = b
Then, we should substitute in this value into our equation and check our work.
y = 3x + 1
If we plug in the other points, this equation yields a true statement, so we know it is correct.
Hope this helps!
Answer:that would be 3 to the 4th power which is 81
Step-by-step explanation:
On seeing the place value of unit digits, we first multiply the unit digits.
If there is a carry over, we add it with the product of unit digit of the first number with the tenth digit of the second number. We accomplish this task by seeing the place values at the respective digits.
Then, we multiply the tenth digit of the first number with the unit digit of the second number by seeing their place values and repeat the process we did before.
By this way, place values are useful for multiplying two digit numbers.
