Given f(x) =
2 cos(7x), for x < -1
2
for x > -1
COS (1x)
What is lim f(x)?
X - - 1
Answer:
A
Step-by-step explanation:
We are given the function:
[tex]\displaystyle f(x) = \left\{ \begin{array}{ll} 2\cos(\pi x) \text{ for } x \leq -1 \\ \\ \displaystyle \frac{2}{\cos(\pi x)}\text{ for } x > -1 \end{array} \right.[/tex]
And we want to find:
[tex]\displaystyle \lim_{x\to -1}f(x)[/tex]
So, we need to determine whether or not the limit exists. In other words, we will find the two one-sided limits.
Left-Hand Limit:
[tex]\displaystyle \lim_{x\to-1^-}f(x)[/tex]
Since we are approaching from the left, we will use the first equation:
[tex]\displaystyle =\lim_{x\to -1^-}2\cos(\pi x)[/tex]
By direct substitution:
[tex]=2\cos(\pi (-1))=2\cos(-\pi)=2(-1)=-2[/tex]
Right-Hand Limit:
[tex]\displaystyle \lim_{x\to -1^+}f(x)[/tex]
Since we are approaching from the right, we will use the second equation:
[tex]=\displaystyle \lim_{x\to -1^+}\frac{2}{\cos(\pi x)}[/tex]
Direct substitution:
[tex]\displaystyle =\frac{2}{\cos(\pi (-1))}=\frac{2}{\cos(-\pi)}=\frac{2}{(-1)}=-2[/tex]
So, we can see that:
[tex]\displaystyle \displaystyle \lim_{x\to-1^-}f(x)=\displaystyle \lim_{x\to -1^+}f(x) =-2[/tex]
Since both the left- and right-hand limits exist and equal the same thing, we can conclude that:
[tex]\displaystyle \lim_{x \to -1}f(x)=-2[/tex]
Our answer is A.

In a certain city, the average 20- to 29-year old man is 69.6 inches tall, with a standard deviation of 3.1 inches, while the average 20- to 29-year old woman is 64.1 inches tall, with a standard deviation of 3.9 inches. Who is relatively taller, a 75-inch man or a 70-inch woman?
Answer:
the 20-29 year old man are relatively taller.
Step-by-step explanation:
for the old man we have next z- score=75-69.6/3.1=1.74
for the old women we have next z-score=70-64.1/3.9=1.51

A restaurant sells soups and salads. Soup costs $5.50, and a salad costs $8. On a particular day, the restaurant sells 58 items and makes $371.50.
Which system of equations can be used to find the amount of soup, x, and salad, y, the restaurant sold?
OA
5.50x = 58
8y = 371.50
OB.
5.50x = Sy
58x = 371.50y
x + y = 58
Oc.
5.50x + 8y = 371.50
x+y = 371.50
OD.
5.50x + 8y = 58

Answer:
The number of non-positive integral values of [tex]k[/tex] are contained in the following set:
[tex]S_{k} = \{-1, 0\}[/tex]
Step-by-step explanation:
Let be the following second order polynomial:
[tex]x^{2}-(k + 1)\cdot x + (k^{2}+k -8) = 0[/tex], [tex]k \le 0[/tex] (1)
Whose roots can be found by the Quadratic Formula:
[tex]x_{1,2} =\frac{k + 1\pm \sqrt{k^{2}+2\cdot k +1 - 4\cdot k^{2}-4\cdot k +32 }}{2}[/tex]
[tex]x_{1,2} = \frac{k+1}{2} \pm \frac{\sqrt{33-2\cdot k -3\cdot k^{2}}}{2}[/tex]
Based on the statement, we have the following system of inequations:
[tex]\frac{k+1}{2} + \frac{\sqrt{33 - 2\cdot k -3\cdot k^{2}}}{2} > 2[/tex] (2)
[tex]\frac{k+1}{2} - \frac{\sqrt{33 - 2\cdot k -3\cdot k^{2}}}{2} < 2[/tex] (3)
By (2) we have:
[tex]k + 1 + \sqrt{33-2\cdot k -3\cdot k^{2}} > 4[/tex]
[tex]\sqrt{33 -2\cdot k - 3\cdot k^{2}} > 4 - (k + 1)[/tex]
[tex]33 - 2\cdot k -3\cdot k^{2} > [4 - (k+ 1)]^{2}[/tex]
[tex]33 - 2\cdot k -3\cdot k^{2} > 16 -8\cdot (k+1)+(k+1)^{2}[/tex]
[tex]33 - 2\cdot k - 3\cdot k^{2} > 16-8\cdot k -8 + k^{2}+2\cdot k + 1[/tex]
[tex]33 - 2\cdot k -3\cdot k^{2} > 9 -6\cdot k + k^{2}[/tex]
[tex]0 > 4\cdot k^{2}-4\cdot k -24[/tex]
[tex]4\cdot k^{2}-4\cdot k -24< 0[/tex]
[tex]4\cdot (k^{2}-k-6) < 0[/tex]
[tex]k^{2}-k - 6 < 0[/tex]
[tex](k -3)\cdot (k+2) < 0[/tex]
The solution is:
[tex]k \in (-2, 3)[/tex]
Likewise, we get the following expression from (3):
[tex]k^{2}-k - 6 > 0[/tex]
[tex](k -3)\cdot (k + 2) > 0[/tex]
The solution is:
[tex]k \in (-\infty, -2)\,\cup\,(3, +\infty)[/tex]
The number of non-positive integral values of [tex]k[/tex] are contained in the following set:
[tex]S_{k} = \{-1, 0\}[/tex]

18. If an apprentice can do a piece of work in 24 days, and the apprentice and
instructor together can do it in 6 days, how long would it take the instructor to do
the work alone?
Answer:
the number of days when instructor do the work alone is 8 days
Step-by-step explanation:
Given that
The apprentice can do the work in 24 days
And, the apprentice and instructor together can do it in 6 days
We need to find out the number of days when instructor do the work alone
So,
[tex]= \frac{1}{6} - \frac{1}{24} \\\\= \frac{4 - 1}{24} \\\\= \frac{3}{24} \\\\= \frac{1}{8} \\\\= 8[/tex]
hence, the number of days when instructor do the work alone is 8 days

Step-by-step explanation:
The common multiples less than 70 of 6 and 8 are: 24 and 48.
If there are 24 blue and green (12 each), there would be 46 yellow and red. Half of 46 is 23, which isn’t an answer choice.
If there are 48 blue and green (24 of each), there would be 22 yellow and red. Half of 22 is 11.
