Answer:
Step-by-step explanation:
AB = 8x + 5
BC = 5x² - 16
5x² - 16 = 8x + 5
5x² - 8x - 21 = 0
Quadratic formula
x = [8 ± √(8² – 4·5(-21))] / [2·5]
= [8 ± √484] / 10
= [8 ± 22] /10
= -1.4, 3
-1.4 is an extraneous solution.
x = 3
AB = 8x+5 = 29
AC = 58
10000 because a number smaller than its is 9999 (4 digits)
Y=1/3x-3/4. I believe is the right equation of the line
Step one- find a perfect square as close as possible to the number
step 2-divide the number by the square root
step 3- calculate the average of your result of step 2 and the root
step 4
Use the result of step 3 to repeat steps 2 and 3 until you have a number that you think is accurate enough for you.
Hello from MrBillDoesMath!
Answer:
10.2
Discussion:
Let the length of the missing side = "s" Applying the Pythagorean theorem to this right triangle gives:
4^2 + s^2 = 11^2 =>
16 + s^2 = 121 => ( 4*4 = 16, 11*11 = 121)
16 - 16 + s^2 = 121 - 16 => (subtract 16 from both sides)
s^2 = 105 =>
x = sqrt (105)
which is approximately 10.2
