I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?

Answers

Answer:

Step-by-step explanation:

Let “ab” represent the digits of the number.

a ≠ 0

Value of the number = 10a+b

a+b + ab = 10a + b

a + ab = 10a

ab = 9a

b = 9

“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99

Answer: 49

Step-by-step explanation:

4x9=36

4+9=13

36+13=49

Sam asked some other children which sport they like. They all choose swimming. Now the most children choose swimming. How many children did Sam ask?

Answers

Answer:

five or more than five

Step-by-step explanation:

From the chart, we know that,

Number of children who chose soccer = 7   (this was the highest)

Number of children who chose swimming = 3

So for swimming to be chosen the most, it should gave been chosen by more than 7 children, i.e. 8 children or more than 8.

So the difference between 8 children and 3 children is = 8 - 3

                                                                                            = 5

Thus, 5 is the least number of other children to chose swimming.

Therefore, Sam asked at least 5 number of children or more than 5.

Which equation below best describes the line on the graph below?
a 2x+6y=8
b 2x-6y=8
c 2x+6y= -8
d 2x-6y= -8
please give steps :)

Answers

Hi! So by looking at your graph, you want to find the slope. First you want to find to points and find the distance between the two. I’ll use the points (-8,4) and (-2,2). Starting at (-8, 4), move down 2 and right 6. This shows that your slope will be -2/6 (further simplified to -1/3)?

Now, looking at each equation given to you in standard form, which will have a slope of -1/3? Your first answer, 2x+6y = 8, has a slope of -1/3, with a y-intercept value of 4/3 (or 1.5). If you look back at your graph again, you can see that the y-intercept is 1.5, so your answer will be A. :)

Solutions 5x + 10 = 5x

Answers

Answer:

I think there is no solution to the equation. (I'm not sure what your asking)

Step-by-step explanation

The equation should equal 0, so you subtract 5x from both sides. Once you do that, it cancels out the 5x and leaves 10=0 which is a false statement.

Real life applications of chain rule

Answers

Answer:

The Chain Rule can also help us deduce rates of change in the real world. From the Chain Rule, we can see how variables like time, speed, distance, volume, and weight are interrelated. A horse is carrying a carriage on a dirt path.

One real-life application of the chain rule is the study of motion in a car that is traveling along a curved path.

What is the chain rule?

The chain rule is a fundamental concept in calculus that enables us to calculate the derivative of composite functions.

Composite functions are functions that are constructed by combining two or more functions. The chain rule tells us how to calculate the derivative of a composite function by breaking it down into simpler parts.

One real-life application of the chain rule is in physics, specifically in the study of motion.

For example, suppose we have a car that is traveling along a curved path. We want to know the rate at which the car is changing its speed at a particular point on the path. To do this, we need to find the derivative of the car's speed with respect to time.

Step-by-step explanation:

Sum of the weight of the boxes of the cart = 10n + 25

where n = number of boxes

10 would be the weight of each box.

total weight of the boxes = weight of each box x number of boxes

10 x n = 10n
