Write a recursive formula: 3, 5, 7, 9, 11, 13, 15, 17, 19, 21

Answers

Answer 1

Answer:

[tex]a_1=3[/tex]

[tex]a_n=a_n_-_1+2[/tex]

Step-by-step explanation:

Recursive formula : an = a(n-1) + d

where d = common difference , an = nth term, and n = number of terms

Because we are just writing the recursive formula rather than the explicit formula, the only defined term will be "d" or the common difference.

Here, the common difference is +2. This is evident as you must add 2 to get to 5 and then add 2 to get to 7 etc.

So d = 2

Plugging this into the recursive formula we get an = a(n-1) + 2

Also it's very important to state the first term which is 3 so a1 = 3

Amira had 3 - of a bag of cat food. The food lasted 7 4 How much cat food did Amira's cats eat per week? ​

Answers

The cat ate 3/7 of a bag per week when the food lasted for 7/4 week.

According to the question,

We have the following information:

Amira had 3/4 of a bag of cat food. The food lasted 7/4 weeks.

Now, we can easily find how much food Amira's cat ate in one week by dividing the total number of bags of food by the number of weeks the food lasted.

So, we have the following expression:

3/4 of a bag = 7/4 weeks

1 week = 3/4 ÷ 7/4

1 week = 3/4 * 4/7 of a bag

1 week = 3/7 of a bag

Hence, the cat ate 3/7 of a bag per week when the food lasted for 7/4 week.

The equation (D) y - 6 = 4(x+8) represents the line passing through the points (-8, 6) and (-11, -6).

What is the point-slope form of a line?

The point-slope form can be used to get the equation of a straight line that traverses a specified point and is inclined at a particular angle to the x-axis. A line exists if and only if each point on it fulfills the equation for the line. This suggests that a linear equation in two variables can represent a line.

The given points are

(x₁, y₁) = (-8, 6)

(x₂, y₂) = (-11, -6)

So, the slope is given by

m = (y₂- y₁)/ (x₂- x₁)

= (-6 -6)/ (-11 -(-8)

= -12/ -3

= 4

Put (x₁, y₁) = (-8, 6) in the equation (y - y₁) = m (x- x₁)

y - 6 = 4(x-(-8)

y - 6 = 4(x+8)

So, the correct option is (D).

The distance travelled by the car in 34 minutes is 22.667 miles.

We are given a car. The car is travelling at a steady speed. It travels 1.5 miles in 2.25 minutes. We need to find the distance travelled by the car in 34 minutes. First of all, we need to find the speed of the car. The speed of the car is the ratio of the distance travelled and the corresponding time taken.

v = s/t

v = 1.5/2.25

v = 0.667

Hence, the speed of the car is 0.667 miles per minute. The speed of the car remains constant throughout its journey. Let the distance travelled by the car be denoted by "d" . The distance travelled in 34 minutes is calculated below.

d = v*t

d = 0.667*34

d = 22.667

Hence, the distance travelled by the car in 34 minutes is 22.667 miles.

Answer: MARK  ME BRAINLIEST I WORK HARD Soda consumption among children and teens is a health concern for a number of reasons. Drinking soda contributes to childhood weight issues, can lead to tooth decay,1 and can contribute to sleep problems. Some studies also suggest that kids who consume soda may have an increased risk for behavioral issues and mental health problems.

This article discusses the potential connection between soft drinks and behavioral problems, the limitations of this research, and other reasons to limit soft drink consumption in kids. It also covers some of the steps you can take if you are dealing with behavior issues and aggression in children.

Health Problems Associated Soft Drinks

Americans have some of the highest consumption rates of soda per capita worldwide.2 And many of those people consuming soda are very young children.

Over the years, there has been a big push to eliminate soft drinks from school vending machines and to educate parents about the risks associated with sugary drinks. Physicians and nutritionists have made it clear that soda provides children with empty calories and contributes to childhood obesity.

Dentists advise parents not to let children drink soda as well. Sugary drinks aren't good for children's teeth and may cause cavities.3

Most soft drinks also contain caffeine. Caffeine can cause headaches, upset stomach, jitteriness, and sleep problems. It’s also been associated with some behavioral problems and nervous system disorders in children.4

In children, it doesn’t take much caffeine to produce unwanted side effects. The American Academy of Pediatrics (AAP) discourages caffeine intake for kids of all ages.4

Recap

Soda and other sugary soft drinks pose a number of health risks including weight problems, dental cavities, headaches, and sleep problems.

Behavior Problems and Soft Drinks

If the health risks aren’t enough to dissuade parents from giving kids soda, the potential mental health concerns that might be associated with soft drink consumption might be a deterrent.

Research suggests that children who consume soda tend to have slightly higher scores on measures of aggression than do children who do not drink soda beverages. It's important to note, however, that the research only suggests that there is a correlation between soda consumption and aggressive behaviors; research has not proven a causal relationship, meaning that more research is needed to determine whether drinking soda causes this type of behavior.

In one 2013 study published in The Journal of Pediatrics found that aggression, withdrawal behavior, and attention problems are associated with soft drink consumption in young children.5

The researchers assessed 2,929 5-year-old children from 20 different U.S. cities. Even after adjusting for factors such as maternal depression, paternal incarceration, and domestic violence, soft drink consumption was still linked to aggressive behavior.

Children who drank four or more soft drinks per day were more than twice as likely to destroy other people's belongings, get into fights, and physically attack people.

However, it is important to note some flaws in the study that make it difficult to make assumptions about the potential impact of drinking soda. The study did not consider serving size, the type of soda, or what beverages specifically count as soft drinks.

While the study suggests there may be a correlation between drinking soda and behavioral aggression, it isn't enough to conclude that there is a causal connection.

One concerning point that this study indicates is that it is quite common for young children to consume soda. Forty-three percent of five years olds were reported to drink one serving of soda per day, while 4% reported drinking four servings per day.

Why Soda Might Affect Mental Health and Behavior

It’s unclear why soda consumption might be connected to aggressive behavior and other mental health issues. Soft drinks are highly processed, and there is not much research on how certain ingredients impact children. Some studies have linked aspartame to irritability6 and sodium benzoate to ADHD-related symptoms.7

Caffeine has also been linked to some behavior problems in children, so researchers suspect the caffeine content may play a role.

An underlying physical condition, such as low blood glucose levels, could also explain the link. Low blood glucose may cause children to crave soda while also causing them to become withdrawn or aggressive.8

However, further research is needed to understand how soda and mental health issues might be connected.

Recap

Soda may contain sugar, aspartame, sodium benzoate, and caffeine, and these ingredients may play a role in triggering negative side effects in kids.

In isosceles triangle dac, ad is congruent to ac. Kiran knows that the base angles of an isosceles triangle are congruent. What additional information does kiran need to know in order to show that ab is a perpendicular bisector of segment cd?.

Answers

If DB and BC are congruent, then AB must be a perpendicular bisector. We conclude that AB is congruent to AB by the reflexive characteristic because DB and BC are congruent.

ADB is congruent to ACB according to the Side-Side-Side, or SSS, congruency rule because the sides AD, AB, and DB in triangle ADB are congruent to the equivalent sides AC, BC, and AB in triangle ACB.

As a result, CPCTC ABD = ABC according to the notion of congruency, where Congruent Parts of Congruent Triangles are Congruent.

Due to the fact that ABD and ABC are linear pair angles,

ABD + ABC = 180°,

ABD + ABD = 2, and ABD = 180°

by virtue of the substitution feature,

ABD = 180°/2 = 90°.

As AB is perpendicular to CD and AB is a perpendicular bisector of CD, ABD = 90° = ABC.

Therefore, the option; DB and BC are congruent is what Kiran needs to know in order to demonstrate that AB is a perpendicular bisector of segment CD.

An equation for the curve that passes through the point (1,0) and whose slope at (x,y) is xe^y is y = -1/x -1.

Define slope.

The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on the straight line, slope can be determined using a variety of approaches. The slope is nothing more than the tangent to the angle formed with the x-axis measured. As a result, it is simply an angle's measurement.

Given,

The curve that passes through the point (1,0) and whose slope at (x,y) is xe^y.

Since x-2 is equal to the slope of the function f(x), we can express that as

dy/dx = x^-2

dx multiplication and integration of both sides:

y = -1/x + C

Connecting the provided point:

0 = -1/1 + C

C = -1

Let X = the number of components that fail before 200 hours . The X has a binomial distribution n = 3 and p = 1 – e^-2.

probability p = 3/2[tex]p^{2} (1-p)[/tex] + 3/3 [tex]p^{3}[/tex].

= 3([tex]1-e^-2)^2[/tex][tex]e^-2[/tex] + ([tex]1-e^-2)^3[/tex]

= [tex](1-e^-^2)^2[3e^-^2 - e^-^2+1][/tex]

= [tex](1-e^{-2} )^2[2e^-2+1][/tex]

Therefore the probability that the equipment will operate for at least 200 hours without failure is [tex](1-e^{-2} )^2[2e^-2+1][/tex].

What is the shortest distance from the point (9, 1) to the line y = 2x + 3? Round to the
nearest tenth.

Answers

The shortest distance from the point (9, 1) to the line y = 2x + 3 is 10 units

The coordinates of the point = (9,1)

The equation of the line is

y = 2x + 3

Here the slope of the line is 2

The shortest distance between the point and the second line will be the perpendicular distance between the point and line

The perpendicular line slope will be -(1/m)

= -(1/2)

This perpendicular line will pass through the point (9, 1)

The point slope form is

y - 1 = -(1/2)(x - 9)

y - 1 = -(1/2x) + 9/2

y = -(1/2)x + 9/2 + 1

y = -(1/2)x + 11/2

Solve the equation

y = 2x + 3

y = -(1/2)x + 11/2

0 = (2 + 1/2)x -5/2

5/2 x = -5/2

x = -5/2 / 5/2

x = -1

Then

y = 2(-1) + 3

y = -2 + 3

y = 1

The distance between the point (9,1) and (-1, 1)

= [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

= [tex]\sqrt{(-1-9)^2+(1-1)^2}[/tex]

= [tex]\sqrt{100}[/tex]

= 10 units

Hence, the shortest distance from the point (9, 1) to the line y = 2x + 3 is 10 units
