Calculus Ch. 1.2 Classwork Problems Evaluating limits Graphically

NISA [10]

Answer:

16) 2

17) -5

18) doesn't exist

19) doesn't exist

20) doesn't exist

21) 3

22) 4

23) 6

Step-by-step explanation:

16) as you move towards -9, the function adopts the value 2

17) as one moves towards x = -6 , from both sides (right and left) the function goes to the value -5

18) As one moves towards x = -4 (from the right and from the left, the functions seems to diverge towards + ∞. So normally the convention for limits stipulates: Undefined or Doesn't exist

19) f(-4) doesn't exist (for same reasons as above (there is a singularity here)

20) As one moves towards 2 from the right, the function gets towards the value 3, while approaching from the left the function goes towards the value 5. So formally we say that the limit doesn't exist (from the left and from the right limits don't agree)

21) f(2) is the well defined value of 3

22) approaching x= 4 from the right and from the left both lead towards the value 4.

23) f(4) is 6

If Sam has 6/8 apples and he gives 4/6 away How much doe she have left?

Margaret [11]

Answer: 1/12 apples left

Step-by-step explanation:

Find the least common multiple (LCM)

8: 8, 16, 24, 32, and so on

6: 6, 12, 18, 24, and so on

Both denominators have a common multiple of 24, so let's use that as the LCM

Whatever you do the denominator, you must do to the numerator, and vice versa.

6*4=24, so you have to multiply 4 to the numerator

4*4=16, so the fraction is 16/24

Then do it for the next fraction

8*3=24, so do 6*3=18

18/24

Then subtract them

18/24 - 16/24= 2/24

Then simplify and you get 1/12

Find the percent of change round to the nearest percent original: 50 new: 70

kykrilka [37]

The percent change is 40%

Step-by-step explanation:

The percent change is given by the formula

$Percent\ change=\frac{New\ value-Original\ value}{Original} * 100$

Here

New value = 70

Original value = 50

Putting the values in the formula

$Percent\ change=\frac{70-50}{50}*100\\=\frac{20}{50}*100\\=0.4*100\\=40\%$

The percent change is 40%

The store bought a pair of shoes for $50, and sold it for $80. What percentage was the markup?

trasher [3.6K]

Answer:

The correct answer is 60%.

Step-by-step explanation:

We know that the store had a profit of $ 30 for the pair of shoes sold.

Now we must transform that $ 30 into a percentage.

And one of the ways in which we can calculate this percentage is with the following percentage formula:

$P= \frac{B}{A} . 100%$

P is the percentage we want to calculate.

The number B is the profit we have obtained, 30

And number A is the total of the product, 50

Thus:

$P= \frac{30}{50} . 100%\\$

$P= 0,6 . 100 %$

P= 60 %

Given this information, we can say that the percentage markup is 60%.
