Here, a = 2, d = 4 - 2 = 2
To find: [tex] a_n[/tex]
[tex]a_n = a + (n - 1)d \\ \\ \therefore \: a_n = 2 + (n - 1)2\\ \\\therefore \: a_n = 2 + 2n -2\\ \\\therefore \: a_n = 2n \\ \\[/tex]

two bicycle riders start from the same point and ride in opposite directions. one rider is moving twice as the other. in 3 hours, they are 72 miles apart. find the rate of each rider.24
Let the speed of one rider = x
The speed of the second rider would e 2x ( twice as fast)
The total speed of the two riders would be x + 2x = 3x
Speed = Distance / time
Using the numbers:
3x = 72/3
Simplify:
3x = 24
Divide both sides by 3:
x = 8
The speed of one rider is 8 miles per hour
The speed of the second rider is 2(8) = 16 miles per hour.

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

D. During the first half of 2015, the weight of Ava's puppy increased two times as fast
Answer:
i think B correct me if wrong pls
Step-by-step explanation:
Option (D) During the first half of 2015, the weight of Ava's puppy increased two times as fast is the correct answer.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. A graph is a diagram that represents the variation of a variable in comparison with that of one or more other variables.
For the given situation,
Sam and Ava compared the weights of their puppies each month during the first half of 2015.
The graph shows the comparison between Sam's and Ava's puppies.
From the graph,
At the beginning of the month both the puppies have same weight. After a month, Ava's puppies weight increased rapidly than Sam's puppy.
Hence we can conclude that option (D) During the first half of 2015, the weight of Ava's puppy increased two times as fast is the correct answer.

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]

Find an equation of the line that passes through the point (2, 4) and is perpendicular to the line 4x + 9y - 2 = 0 (let x be the independent variable and y be the dependent variable.
Answer:
y = 9/4x -1/2
Step-by-step explanation:
4x + 9y -2=0
solve for y: 4x-2=-9y
(4x-2)/-9 =
y =4/-9x-2/9
perpendicular means reciprocal of slope. So 4/-9 changesz to 9/4

Panchito needs to make 80 ml of a 39% alcohol solution. He is going to make it by mixing a 50% alcohol solution with a 6% alcohol solution. How much if each should he use?
Answer:
60ml of the 50% alcohol solution and 20ml of the 6% alcohol solution
Step-by-step explanation:
We can build a system of equation for solve this problem
x = first solution
y = second solution
x + y = 80
0.5x + 0.06y = 80 * 0.39
x + y = 80
0.5x + 0.06y = 31.2
x = 80 -y
0.5(80-y) + 0.06y = 31.2
40 - 0.5y + 0.06y = 31.2
-0.44y = -8.8
y = 20
x = 80 - 20 = 60
Solve the system of equations using substitution or graphing.
