Answer:

7.41717\times 10^4

Step-by-step explanation:

We are asked to write 74171.7 in scientific notation.

To write a number in scientific notation, we need to two factors such that one is between 0 and 10 and second is power of 10.

To find the first factor, we will move the decimal to 4 units to right as:

7.41717

The second factor would be 10^4 as 7.41717 times 10^4 equals 74171.7.

Therefore, our required number would be 7.41717\times 10^4.

one number is equal to the square of another. find the numbers if both are positive and their sum is 1122
statuscvo [17]

Answer:

One number is 561

The other number is 23.6854

Step-by-step explanation:

x = y^2                One number = the square of another

x + y^2 = 1122     The sum of the two numbers is 1122

Substitute y^2 in for x on the second equation.

y^2 + y^2 = 1122    Combine like terms on the left

2y^2 = 1122            Divide by 2

y^2 = 1122/2

y^2 = 561                Take the square root of both sides.

y = 23.6854            

x = y^2

x = 561

y^2 = 561

<u>According to intersecting chords theorem:</u>

  • 21(2x - 6) = 30(x + 1)
  • 42x - 126 = 30x + 30
  • 42x - 30x = 126 + 30
  • 12x = 156
  • x = 156/12
  • x = 13

<u>Find the value of YZ:</u>
