The explicit formula for the arithmetic sequence 12, 5, -2, -9,..is a(n) = -7n + 19.
To find the explicit formula for this arithmetic sequence, we first need to determine the common difference, which is the amount by which each term differs from the previous term.
d = 5 - 12 = -7
d = -2 - 5 = -7
d = -9 - (-2) = -7
Since the common difference is -7, we can use the formula for an arithmetic sequence:
a(n) = a (1) + (n - 1) d
where a(n) is the nth term of the sequence, a (1) is the first term, n is the term number, and d is the common difference.
Plugging in the given values, we get:
a(n) = 12 + (n - 1) (-7)
Simplifying, we get:
a(n) = -7n + 19

The explicit formula for the arithmetic sequence will be f(n) = 19 -7n.
f(n) = a + (n - 1) d,
where an is the first term and is the explicit formula for an arithmetic series.
d = Common Difference
n = number of terms
The provided arithmetic series is = 12, 5, -2, -9.
First term: a = 12.
Common variation: d= 5-12= 7

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 8 times out of 10 attempts. Tasha has hit the ball 9 times out of 12 attempts. Which player has a ratio that means they have a better batting average?
Tasha, because she has the lowest ratio since 0.75 < 0.8
Tasha, because she has the highest ratio since 48 over 60 is greater than 45 over 60
Jana, because she has the lowest ratio since 0.75 < 0.8
Jana, because she has the highest ratio since 48 over 60 is greater than 45 over 60
Jana, because she has the highest ratio since 8/10 is greater than 9/12.
What is ratio?A ratio is a comparison of two numbers or quantities expressed in relation to each other. It represents the relative size or magnitude of one quantity with respect to another. Ratios are typically written as a fraction, with the first number being the numerator and the second number being the denominator, and can also be expressed as a decimal or percentage.
What is batting average?Batting average is a statistical measure used in baseball to evaluate a player's performance at the plate. It is calculated as the ratio of a player's total number of hits to their total number of at-bats (the number of times they attempt to hit the ball).
In the given question,
A higher batting average indicates a better performance, since it means the player is successfully hitting the ball more often.
In this case, we are given the number of hits and attempts for two players, Jana and Tasha. To compare their batting averages, we need to calculate the ratio of their hits to their attempts.
Jana has hit the ball 8 times out of 10 attempts, so her batting average is 8/10 = 0.8.
Tasha has hit the ball 9 times out of 12 attempts, so her batting average is 9/12 = 0.75.
To determine which player has the better batting average, we compare their ratios. Since 0.8 is greater than 0.75, Jana has the higher ratio and therefore the better batting average.
So, the answer is Jana, because she has the highest ratio (8/10 = 0.8), which means she has the better batting average compared to Tasha (9/12 = 0.75).

To rewrite the quadratic equation 9 = -3x^2 -18x - 25 in the form y = a(x - p)^2 + q, we need to complete the square. First, we factor out the leading coefficient of -3:
-[tex]3(x^2 + 6x + 25/3) = -3(x^2 + 6x + 9 + 16/3)[/tex]
Next, we add and subtract 9 inside the parentheses to complete the square:
[tex]-3(x^2 + 6x + 9 - 9 + 16/3) = -3((x + 3)^2 - 1/3)[/tex]
Simplifying the expression further, we get:
[tex]-3(x + 3)^2 + 3 = y[/tex]
Comparing this to the standard form y = a(x - p)^2 + q, we can see that a = -3, p = -3, and q = 3. Therefore, the value of p is -3.
Please hit brainliest if this helped!
Answer:
[tex]p = - 3[/tex]Step-by-step explanation:
To find:-
The value of p .Answer:-
We are here given that a quadratic equation is written in the form of y = a(x-p)² + q and we are interested in finding out the value of "p" .
So , the given quadratic equation to us is ,
[tex]\longrightarrow y = -3x^2-18x-25\\[/tex]
Now complete the square on the RHS side of the equation as ,
Firstly make the coefficient of x² as 1 . This can be done by taking out -3 as common.
[tex]\longrightarrow y = -3\bigg(x^2+6x +\dfrac{25}{3}\bigg)\\[/tex]
we can rewrite it as ,
[tex]\longrightarrow y = -3\bigg( x^2+2(3)(x) +\dfrac{25}{3}\bigg) \\[/tex]
Add and subtract 3² , as ;
[tex]\longrightarrow y = -3\bigg( x^2+2(3)(x) + 3^2-3^2+\dfrac{25}{3}\bigg) \\[/tex]
Rearrange the terms as ,
[tex]\longrightarrow y = -3 \left\{ (x^2+2(3)(x) + 3^2) - 9 +\dfrac{25}{3}\right\} \\[/tex]
Notice the terms inside the small brackets are in the form of [tex]a^2+b^2+2ab[/tex] which is the whole square of [tex] (a+b)[/tex] . Hence , we can write it as ,
[tex]\longrightarrow y =-3\bigg\{ (x+3)^2 + \dfrac{-27+25}{3}\bigg\} \\[/tex]
Simplify,
[tex]\longrightarrow y = -3\bigg\{ (x+3)^2 -\dfrac{2}{3}\bigg\} \\[/tex]
Open the curly brackets by multiplying the terms inside the brackets by -3 as ,
[tex]\longrightarrow y = -3(x+3)^2 - 2 \\[/tex]

when performing regression, why would you want to have a quadratic term? group of answer choices you never want to add a quadratic term when performing regression to better fit a scatterplot with too many outliers to better fit a scatterplot that shows a curve in the data to better fit linear data
So, the right response is that, in order to more accurately fit the scatterplot that depicts a curve in the data, you need add a quadratic component while performing regression.
What is the quadratic term count?As ax² +bx + c, a quadratic equation can be expressed. In a quadratic equation, the largest exponent is 2, which limits the number of terms to a maximum of 3. These terms are exponent 2 (ax²) and exponent 1 (bx) fixed term.
Regression can be improved by including a quadratic component to better match scatterplots of data that display curves. This is so that the independent and dependent variables can have a nonlinear connection, which is made possible by a quadratic term. A quadratic component can assist capture inherent curvature of a data and enhance the fit of a regression model in cases where the connection between both the variables isn't really strictly linear.
A quadratic term may not be appropriate or required, though. A quadratic factor would not increase the model's fit if the variables' relationships are strictly linear and might even result in overfitting. In addition, if the scatterplot contains too many anomalies or the data is not consistent, adding a quadratic factor might not be beneficial.

(Find the Smallest Value) Write an application that finds the smallest of several integers. Assume that the first value read specifies the number of values to input from the user.
To find the smallest of several integers, you will need to write a program that takes in a number of values specified by the user as input, and then outputs the smallest value. First, you will need to create a loop that reads in the number of values specified by the user. To do this, you can use a 'for' loop that reads in the values until it reaches the user-specified number of values. Inside the loop, you can create a variable to store the smallest value and compare each value to the smallest value to determine if it is smaller. If the value is smaller, then the smallest value should be updated.
Finally, once the loop has gone through all of the values, the smallest value should be outputted. In summary, to find the smallest value of several integers, you will need to use a 'for' loop to read in the specified number of values from the user, compare each value to the smallest value, and update the smallest value if it is smaller. Then, you can output the smallest value once the loop is complete.

To find the current that supplies the maximum wattage, we need to take the derivative of the power function with respect to I, set it equal to zero, and solve for I. The derivative of the power function is:
dW/dI = 120 - 24I
Setting this equal to zero and solving for I, we get:
120 - 24I = 024I = 120I = 5
Therefore, the current that supplies the maximum wattage is 5 amps. We can verify that this is a maximum by checking the second derivative of the power function with respect to I. The second derivative is:
d^2W/dI^2 = -24Since the second derivative is negative, the function has a maximum at I = 5.

Answer:
We can find the current that supplies the maximum wattage by finding the value of I that maximizes the power function W(I) = 120I - 12I^2.
To do this, we can take the derivative of W with respect to I and set it equal to zero:
dW/dI = 120 - 24I = 0

Solve for x in the triangle.
Answer:
D. 87
Step-by-step explanation:
You want to know the measure of the angle opposite the longest side in a triangle with side lengths 13, 16, and 20 inches.
Angle relationsThe angle x is opposite the side of length 20 inches in this triangle, which is the longest side. That tells you x is the largest angle.
The largest angle in any triangle is never less than 60°. This eliminates all answer choices except the last one:
x = 87
Law of CosinesIf you want to go to the trouble to solve the triangle, the law of cosines is helpful. For sides a, b, c and angle C, it tells you ...
c² = a² +b² -2ab·cos(C)
Solving for the angle, we have ...
C = arccos((a² +b² -c²)/(2ab))
C = arccos((13² +16² -20²)/(2·13·16)) = arccos(25/416) ≈ 86.55°

In Rosettenville, a suburb of Johannesburg, South Africa, Robert Brozin and Fernando Duarte acquired the Chicken Land restaurant in 1987, launching Nando's.
The eatery was renamed Nando's in honor of Fernando. The restaurant incorporated influences from former Mozambican Portuguese colonists, many of whom had relocated to Johannesburg's southeast after their country gained independence in 1975. Expansion was an essential component of their vision from the beginning. Nando's had already grown from one restaurant in 1987 to four by 1990. It became increasingly difficult to implement a common strategy and decision-making became inefficient as new outlets were maintained as separate businesses.
In 1995, Nando's International Holdings (NIH) was established as a new international holding because managing this growingly complex global structure had become extremely challenging. The South African branch of Nando's Group Holdings (NGH) was successfully listed on the Johannesburg Stock Exchange on April 27, 1997. NGH was 54% owned by NIH, with the remaining 26% available to the general public and former joint venture partners. The main goals of the share offer and listing were to broaden the group's capital base and enable group restructuring.

A rectangle measures 3 2/3 inches by 1/2 inches. What is its area?
the rectangle has a surface area of 11/6 square inches and perimeter is 23/3 inches.
How is area and perimeter determined?We must multiply the length by the width of the rectangle to determine its area. Applying the provided metrics, we have:
Area is equal to the product of length and width.
Area is equal to (11/3) x (1/2) inches.
11/6 square inches is the area.
As a result, the rectangle has a surface area of 11/6 square inches.
The lengths of all four sides must be added up in order to determine the rectangle's perimeter. Applying the provided metrics, we have:
Perimeter equals 2 (length plus width).
Perimeter equals 2 (3 2/3 inches plus 1 inch).
perimeter equals two (11/33 inch plus 1/2 inch).
P = 2 (or 23/6 inches)
Diameter is 23 3/8 inches.
As a result, the rectangle's perimeter is 23/3 inches.

Kate plans to save 5% of her income. She just earned 80.Howmuchmoneyshouldsheputintosavings?
$4
Multiply 80 by 0.05 to get the answer of $4
Answer:
