Let A be a non-empty set of rational numbers and B = {a+1 : a ∈ A} (sometimes denotes A + 1). Prove carefully that sup(B) = sup(

liraira [26]

Answer:

a is an element of A; a is a rational number

(a+1) is element of B

Step-by-step explanation:

(a+1) = sup(A), which are the elements of B.

(a+1) + 1 = sup(B)

Recall a+1 = sup(A),

Therefore,

sup(A )+ 1 = sup(B)

sup(B) = sup(A) + 1 ___proved

Sup(A) means supremum of set A. It means least element of another set (say set B), that is greater than every element in set A

Need to find the value of y

alexgriva [62]

Answer:

√55

Step-by-step explanation:

Notice that the small triangle in the bottom corner shares an angle with the overall triangle. Also, they are both right triangles. Therefore, they are similar triangles.

Notice that the large triangle at the top shares an angle with the overall triangle and is also a right triangle. Therefore it is also similar to the overall triangle and the smaller triangle.

Writing a proportion between the small and large triangles:

y / 11 = 5 / y

y² = 55

y = √55

Please help! Just with Part B...

BARSIC [14]

Answer:

a) Number of calories burned in $x$ hours of cycling $600x$ and Number of calories burned in $y$ hours of Swimming is $400y$ .

b)The equation in general form that relates number of hours of cycling and swimming carols needs to perform to loose 5 pounds is $6x+4y=160$ .

Step-by-step explanation:

Given:

5 pounds of body fat = 16000 calories

Number of calories burn in 1 hour of cycling = 600

Number of calories burn in 1 hour of swimming = 400

Part a:

We need to find number of calories will Carol burn in $x$ hours of cycling and number of calories will Carol burn in $y$ hours of swimming.

Solution:

Now we know that;

1 hr of cycling = 600 calories burned

$x$ hr of cycling = Number of calories burned in $x$ hours of cycling.

By using Unitary method we get;

Number of calories burned in $x$ hours of cycling = $600x$

Also we know that;

1 hr of swimming= 400 calories burned

$y$ hr of swimming = Number of calories burned in $y$ hours of swimming.

By using Unitary method we get;

Number of calories burned in $y$ hours of Swimming = $400y$

Hence Number of calories burned in $x$ hours of cycling $600x$ and Number of calories burned in $y$ hours of Swimming is $400y$

Part b:

We need to write equation in general form that relates number of hours of cycling and swimming carols needs to perform to loose 5 pounds.

Solution:

Now given;

5 pounds = 16000 calories.

So we can say that;

Total number of calories to be burn is equal to sum of Number of calories burned in $x$ hours of cycling and Number of calories burned in $y$ hours of Swimming.

framing in equation form we get;

$600x+400y=16000$

Now dividing both side by 100 we get;

$\frac{600x}{100}+\frac{400y}{100}=\frac{16000}{100}\\\\6x+4y=160$

Hence the equation in general form that relates number of hours of cycling and swimming carols needs to perform to loose 5 pounds is $6x+4y=160$ .
