One-sided Limit
Given a piecewise function, we can find the limit when the variable approaches a specific value in the boundary of two pieces.
Special care must be taken to determine what function will be used to calculate the limit according to the conditions of the independent variable.
The given function p(t) has 3 pieces or subfunctions according to different conditions of t. We need to calculate:
[tex]\lim _{x\to 2^{-}}p(t)[/tex]
We must find the subfunction where a value of t is close to 2 but is less than 2.
The correct subfunction is
[tex]p(t)=t^3\qquad -2\le t\le 2[/tex]
Taking the limit:
[tex]\lim _{x\to 2^{-}}p(t)=\lim _{x\to 2}t^3=2^3=8[/tex]
Correct option: c. 8

Sam lives near a lagoon in the Caribbean that is populated by flamingos. Sam decides to figure out approximately how many flamingos live in the area. He catches 45 flamingos, put tags on them, and releases them. Later, he catches 280 flamingos, 30 of which are tagged. To the nearest whole number, what is the best estimate for the flamingo population?

Answer:
about 330
Step-by-step explanation:
280 rounded is 330 and 30 is already rounded so you would add 30 plus 330

Jasmine's cell phone company charges her $35 a month for phone service plus 0.50 for each text message. How many text messages does she send in a month if her bill was $52. explain how you did the math and let T= the # of text messages
Answers
Answer:
Step-by-step explanation:
you have to divid 52 by 0.50 i think
The equation is: y = 0.50x + 35
Now you’re going to plug 52 in y as the total.
52 = 0.50x + 35
-35 = 0.50x -35
(Then subtract both sides by 35)
It will equals to: 17 = 0.50x
17 = 0.50x
———= ———-
0.50 = 0.50
Now divide both sides by 0.50)

Answers
Answer:
x = 2/3
Step-by-step explanation:
To find x-intercept/zero, subtract y = 0
0 = 3x + 2
Move variable to the left-hand side and change its sign
-3 = 2
Divide both ides of the equation by - 3
x = - 2/3
Solution
x = - 2/3
Alternate form
x = - 0.6

(2y+14.6+3.8)-(34.8m+15.6+2y)
Answers
Answer:
5.6
Step-by-step explanation:
You most likely will end up putting it in slope form y=mx+b
(2y+14.6+3.8)-(34.8m+15.6+2y) collect like terms
(2y+18.4)-(34.8m + 15.6 + 2y) = 2.8 + 34.8m
2y-2y= 0
18.4 - 15.6= 2.8
34.8m -0 = 34.8m
2.8 + 34.8m ( I think we should further simplify)
so minus 2.8 on both sides
34.8m = -2.8(divide by 34.8 on both sides)
m = -7/87
Plug in
(2y+14.6+3.8)-(34.8(-7/87)+15.6+2y) collect like terms
(2y+18.4)-(-2.8 + 15.6 + 2y) collect like terms
(18.4)-(12.8)= 5.6
2y-2y = 0
34.8(-7/87)= -2.8
18.4 - 12.8 = 5.6
A product's demand per period follows a normal distribution with mean of 60 and standard deviation of 10. The lead time is 3 periods. What order-up-to level should be used to achieve at least a 90% in-stock probability?
Answers
Answer:
209
Step-by-step explanation:
Since the lead time is 2 periods at the time of order, the stocks should last for 3 periods with the 90% probability.
The z-value of 90$ in stock probability = 1.7
Mean of the demand over is (1 + 1 + 1 ) or (2+1 which is 3)
= 60 x 3 = 180
Now the standard deviation of demand over the three periods = 17.3
Therefore, the order up level would be = 180 + ( 1.7 x 17.3 )
= 209
Susan is buying supplies for a party. Spoons only come in bags of 12 and forks only come in bags of 22.
What is the least number of spoons and the least number of forks she can buy so that she has the same number of each?.
Answers
Answer:
The least number of spoons = 11 spoons
The least number of forks = 6 forks
Step-by-step explanation:
We are told in the question:
Spoons only come in bags of 12
Forks only come in bags of 22.
This is an LCM question, hence, we find the Multiples of 12 and 22
The first common multiple is found and this is the lowest common multiple.
Multiples of 12:
12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156
Multiples of 22:
22, 44, 66, 88, 110, 132, 154, 176
Therefore,
LCM(12, 22) = 132
The least number of supplies she can have is 132.
So therefore,
The least number of spoons = 132 ÷ 12 bags of spoons = 11 spoons
The least number of forks = 132 ÷ 22 bags of forks = 6 spoons.
9. A car is traveling in a straight line path at a maximum speed of 7.00 m/s. The
driver of the vehicle applies the brakes bringing the car to a stop after traveling
10.0 m. What is the magnitude of the car's acceleration to the nearest
hundredths place?
Answers
Answer:
30mph
Step-by-step explanation:
The magnitude of the car's acceleration is 2.45 m/[tex]\rm sec^2[/tex] and this can be determined by using the equation of kinematics.
Given :
A car is traveling in a straight-line path at a maximum speed of 7.00 m/s.The driver of the vehicle applies the brakes bringing the car to a stop after traveling 10.0 m.According to the kinematics:
[tex]\rm v = u + at[/tex] --- (1)
where v is the final speed, u is the initial speed, a is the acceleration and t is time.
Now, put the known terms in equation (1).
0 = 7 + at
at = -7
[tex]\rm t = -\dfrac{7}{a}[/tex] --- (2)
From the kinematics the displacement is given by the equation:
[tex]\rm S =ut+\dfrac{1}{2}at^2[/tex]
Now, put the values of u, S, and t in the above equation.
[tex]10=7\times \dfrac{-7}{a}+\dfrac{1}{2}\times a \times \dfrac{49}{a^2}[/tex]
Now, simplify the above equation.
[tex]10=-\dfrac{49}{a}+\dfrac{49}{2a}[/tex]
20a = -49
a = -2.45
So, the magnitude of the car's acceleration is 2.45 m/[tex]\rm sec^2[/tex].

In a certain chemical, the ratio of zinc to copper is 4 to 17 . A jar of the chemical contains 663 of copper. How many grams of zinc does it contain?
Answers
Answer:
The jar contains 156 grams of zinc
Step-by-step explanation:
Ratios
Let's call
Z=gr of zinc
C=gr of copper
We know the ratio between them in a certain chemical is:
[tex]\displaystyle \frac{Z}{C}=\frac{4}{17}[/tex]
The jar of the chemical contains C=663 gr of copper. Calculate the grams of zinc by solving the above relation for Z:
Multiplying by C:
[tex]\displaystyle Z=\frac{4}{17}\cdot C[/tex]
Substituting the value of C:
[tex]\displaystyle Z=\frac{4}{17}\cdot 663[/tex]
Z=156 gr
The jar contains 156 grams of zinc

Answer:

Step-by-step explanation:15% of 306=45.9
306-45.9=260.1
Answer:
351.9
Step-by-step explanation:
x/306=15/100. then I cross multiplied. And when I do I get 100x/100=4590/100.
I cross out the 100/100 and I leave with x, then I divide 4590 with 100 and get 45.9. So x=45.9.
Then I added the price it was sold..=306+45.9=351.9
