2. The sum of the reciprocals of two consecutive positive integers is 17/72. Write an equation that can be used to find the two
Lena [83]
To answer this item, we let x be the first positive integer. Then, the second would be x+1. Their reciprocals would be 1/x and 1/(x+1). Then, the equation that would best represent the scenario above is,
                            1/x + 1/(x+1) = 17/72
Solving the equation above,
                           ((x+1) + x) / (x)(x+1) = 17/72
If we take the numerators of both sides of the equation,
                              (x+1) + x = 17
The value of x from the equation is 8 and x+1 would be 9. Thus, the answer would be 8 and 9.

A student needs to make a circular cardboard piece with an area between 154 square inches and 616 square inches. The function f(
Nezavi [6.7K]
The area of the circle by definition is given by:
 f (r) =  \pi  * r ^ 2

 For f (r) = 154:
 154 =  \pi  * r ^ 2

 Clearing r we have:
 r ^ 2 = 154 / 3.14

 r =  \sqrt{154/3.14} 

 r = 7
 For f (r) = 616:
 616 = \pi * r ^ 2
 Clearing r we have:
 r ^ 2 = 616 / 3.14 r = \sqrt{616/3.14} r = 14
 Answer:
 
a reasonable domain for f (r) is:
 
7 <r <14

Please help I don’t want to give up it’s getting hard
Svetradugi [14.3K]

Answer:

144 goes with 12, 36 goes with 6, 9 goes with 3, and 121 goes with 11.

Step-by-step explanation:

The second number stated in each phrase is time itself to create the first number. For example, 144. If we take the second number in the number phrase (12) and time it by itself (12 * 12) it equals 144. This applies to each number phrase.
