Write the explicit formula for the arithmetic sequence.
3, -3, -9, -15, -21, ...
A) an = 7 - 4n
B) an = 6 - 3n
C) an = 9 - 6n
D) an = 18 - 15n
Option C
The explicit formula for the arithmetic sequence is [tex]a_n = 9 - 6n[/tex]
Solution:
Given that the arithmetic sequence is:
3, -3, -9, -15, -21, ...
To find: Explicit formula for the arithmetic sequence
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
Where [tex]a_n[/tex] is nth term of sequence
n is the term's location
[tex]a_1[/tex] is the first term of sequence
d is the common difference between terms
In an arithmetic sequence, the difference between successive terms is constant. This means that we can move from any term to the next one by adding a constant value.
In the given sequence:
3, -3, -9, -15, -21, ...
[tex]a_1 = \text{ first term } = 3[/tex]
d = difference between any two terms in sequence
[tex]d = a_2 - a_1[/tex]
d = -3 - (3) = -6
Substituting the values in above formula,
[tex]a_n = 3 + (n - 1)(-6)\\\\a_n = 3 -6n + 6\\\\a_n = 9 - 6n[/tex]
Thus the explicit formula to find any term in sequence is found
if a rectangular swimming pool is 10 meters wide and 15 meters long what is the perimeter
Answer:
50m
Step-by-step explanation:
Information from the question:
The length is 15m
The width is 10m
Length is represented by "l"
Width is represented by "w"
The perimeter is the total of its side lengths. A rectangle has four sides that are two lengths and two widths.
Use the formula for perimeter:
P = 2(l + w) Put in the length and width measurements
P = 2(15m + 10m) Add inside the brackets
P = 2(25m) Multiply
P = 50m Answer
Therefore the perimeter of the rectangular swimming pool is 50 meters.

a coach bought some baseball bats and 5 baseball gloves. Let b represent the number of bats. Write an expression that can be used to find the total cost of bats and gloves. Then find the total cost if he bought three bats.
The expression for the total cost of bats and gloves is b*x + 5*y. To find the total cost when three bats are bought, you need to know the costs of a bat (x) and a glove (y), and substitute those into the expression.
Explanation:Assume that the cost of a baseball bat is 'x' dollars and each glove costs 'y' dollars. The total cost can be calculated by making 'b' the number of bats and adding the cost of 5 gloves. Therefore, the expression representing the total cost is b*x + 5*y.
Now, if the coach bought 3 bats, and we're given the costs for a bat and a glove, we can substitute '3' for 'b', 'x' for the cost of a bat, and 'y' for the cost of a glove.
For example, if a bat is $50 (x=50) and a glove is $20 (y=20), the total cost would be: 3*50 + 5*20 = 250 dollars.

#SPJ2
Final answer:
The expression for total cost of baseball bats and gloves is 'b times the number of bats plus 5 times the cost of a glove', where 'b' represents the cost of a bat. In the bat and ball problem, if a bat costs $1 more than the ball and together they cost $1.10, the ball costs $0.05. For three bats, the total cost is $3.15.
Explanation:
The question posed is a classic algebra problem from mathematics often used to illustrate a common cognitive error. To write an expression for the total cost of the baseball bats and gloves, let the cost of each bat be represented by 'b' and assume each glove has a fixed cost 'g'. The expression is then b times the number of bats plus 5 times the cost of a glove. However, we require additional information regarding the cost of individual gloves to complete this expression.
Turning to the bat and ball problem, if a bat and ball together cost $1.10, and the bat costs $1 more than the ball, we can set up the following equations where 'x' is the cost of the ball:
x + (x + $1) = $1.10
2x + $1 = $1.10
2x = $1.10 - $1.00
2x = $0.10
x = $0.05
Thus, the ball costs $0.05 and the bat costs $1.05. Finding the cost of three bats, we simply multiply $1.05 by 3 to get $3.15.

What is the maximum value of 4(x + 7)(2 - x), over all real numbers x?
Answer:
The maximum value of function is 81 .
Step-by-step explanation:
Given function as :
y = 4 (x + 7) (2 - x)
Now, The function can be written as
y = 4 (2 x - x² + 14 - 7 x)
y = 4 ( - x² - 5 x + 14)
y = - 4 x² - 20 x + 56
Now, For maximum value of function , differentiation of y with respect to x
[tex]\frac{\partial y}{\partial x}[/tex] = 0
Or, [tex]\frac{\partial ( - 4x^{2} - 20 x +56)}{\partial x}[/tex] = 0
Or, - 8 x - 20 = 0
Or, - 8 x = 20
∴ x = [tex]\dfrac{-20}{8}[/tex]
i.e x = [tex]\dfrac{-5}{2}[/tex]
Now, Putting the value of x in the given equation
y = - 4 ( [tex]\dfrac{-5}{2}[/tex])² - 20 ( [tex]\dfrac{-5}{2}[/tex]) + 56
Or, y = - 4 ([tex]\dfrac{25}{4}[/tex]) + 50 + 56
Or, y = - 25 + 50 + 56
∴ y = 81
So, The maximum value of function is 81
Hence,The maximum value of function is 81 . Answer

Car A travels 120 miles in the same time that car B travels 150 miles. If car B averages 10 mph faster than car A, what is the speed of each car?
Answer:
Car A: 40 mph
Car B: 50 mph
Step-by-step explanation:
For the same travel time, the ratio of speeds is the same as the ratio of distances:
(speed B)/(speed A) = 150/120 = 5/4
The difference in the (reduced) ratio units is 1, so 1 ratio unit corresponds to 10 mph. Multiplying the reduced ratio by 10 mph, we get ...
Speed B is 50 mph; speed A is 40 mph.

Find the product for 2(2n + 3)
To find the product for 2(2n + 3), use the distributive property to multiply 2 with each term inside the parentheses, resulting in 4n + 6.
Explanation:The question asks to find the product for 2(2n + 3). To solve this, we need to use the distributive property of multiplication over addition, which states that a(b + c) = ab + ac. Applying this rule to the given expression, we multiply 2 with each term inside the parentheses.
First, multiply 2 by 2n to get 4n. Next, multiply 2 by 3 to get 6. Therefore, the expression simplifies to 4n + 6.
We have successfully used the distributive property to find that the product of 2(2n + 3) is 4n + 6.

The items are classified as M1, M2, or neither based on their liquidity and spendability. A line of credit and traveler's checks are neither M1 nor M2 as they are not actual money. Physical currency and money in a checking account are classified as M1, while money in a money market account is classified as M2.
Explanation:M1 refers to the narrowest definition of the money supply, which includes only the most liquid forms of money that can be easily spent. M2 is a broader measure of the money supply and includes M1 as well as other less liquid forms of money. Neither refers to items that do not fit into either M1 or M2.
a. Your $5,000 line of credit on your Bank of America card is neither in M1 nor M2 as it is not actual money but a credit limit.
b. $50 dollars' worth of traveler's checks you have not used yet is neither in M1 nor M2 as they need to be exchanged for cash before they can be spent.
c. $1 in quarters in your pocket is in M1 as it is physical currency that can be spent.
d. $1200 in your checking account is in M1 as it is a liquid form of money that can be spent.
e. $2000 you have in a money market account is in M2 as it is a less liquid form of money that can be accessed but may have restrictions or penalties for withdrawal.

1. f(2) = 6
2. Slope, m = [tex]$ \frac{7}{2} $[/tex]
Step-by-step explanation:
Problem 1:
Given f(x) = |3x|
To find f(2), substitute x = 2.
⇒ f(2) = |3(2)|
= |6|
= 6
Problem 2:
The given equation is: 2y = 7x + 8
The general equation of the line is: y = mx + c, where m is the slope of the line.
Therefore, we reduce the given equation to the general form of the line.
Dividing the given equation by 2, we get:
y = [tex]$ \frac{7}{2}x + \frac{8}{2} $[/tex]
[tex]$ \implies y = \frac{7}{2}x + 4 $[/tex]
Thus, slope, m = [tex]$ \frac{7}{2} $[/tex] which is the answer.
Problem 3:

= 28 miles/gallon of gas
Therefore, with 3.7 gallons of gas, we can travel 3.7 X 28 miles
= 103. 6 miles

In ordered pair a solution [tex]y\geq x-5?[/tex]
Answer:
The graph is plotted below.
One ordered pair as solution is (0, 0).
Step-by-step explanation:
Given:
The inequality is given as:
[tex]y\geq x-5[/tex]
In order to plot it, we first replace '≥' by '=' sign. This gives,
[tex]y = x-5[/tex]
Now, we plot the above line. For that, we need the x and y intercepts.
At x-intercept, y = 0. So,
[tex]0=x-5\\x=5[/tex]
The point is (5, 0)
At y-intercept, x = 0. So,
[tex]y=0-5\\y=-5[/tex]
The point is (0, -5)
Now, plot these two points and draw a line passing through these two points. The graph is shown below.
Now, replace '=' by '≥' sign. Since, 'y' is greater than equal to 'x - 5'. So, the solution region is above the given including the values on the line.
Therefore, any ordered pair in the solution region is a solution of the given inequality. From the graph, one such ordered pair is (0, 0).
This can be verified from the inequality also.
[tex]0\geq 0-5\\0\geq -5(True)[/tex]
So, one ordered pair is (0, 0).
Ivan buys candy that costs $7 per pound. He will buy at most 9 pounds of candy. What are the possible amounts he will spend on candy?
Use c for the amount (in dollars) Ivan will spend on candy.
Write your answer as an inequality solved for c.
Answer: 7c ≤ 63
Ivan will buy at most 9 pounds of candy, which means that multiplying 9 by 7, the cost of the candy, will get your answer: 63. Plug these values into an inequality with a less than or equal to sign (≤) facing away from 63 and you're done!
The possible amounts Ivan will spend on candy can be represented as c ≤ 7.
Explanation:Let's denote the amount Ivan will spend on candy as c. The cost of candy is $7 per pound, and Ivan will buy at most 9 pounds of candy. Therefore, the maximum amount he could spend on candy is 9 pounds multiplied by $7 per pound, which is 9c ≤ 63.
Since we are looking for possible amounts, we can rewrite this inequality as c ≤ 63/9, which simplifies to c ≤ 7.
So, the possible amounts Ivan will spend on candy are values less than or equal to $7.

Since probability of choosing a lemon lime doesn't effect probability of choosing orange drink, therefore, both events are mutually exclusive.
We know that probability of two mutually exclusive events is equal to the sum of both probabilities.
[tex]P(\text{Lemon-lime or orange})=P(\text{Lemon-lime})+P(\text{Orange})[/tex]
[tex]P(\text{Lemon-lime or orange})=\frac{1}{3}+\frac{1}{3}[/tex]
[tex]P(\text{Lemon-lime or orange})=\frac{1+1}{3}[/tex]
[tex]P(\text{Lemon-lime or orange})=\frac{2}{3}[/tex]
Therefore, the probability of choosing a lemon lime or orange is [tex]\frac{2}{3}[/tex].
