Answer:
3.2 miles
Step-by-step explanation:
Given that Mary drives 9 miles north and 6 miles east to get there, the resultant miles will be achieved by using pythagorean theorem
R = sqrt ( 9^2 + 6^2 )
R = sqrt ( 81 + 36 )
R = sqrt ( 117 )
R = 10.82 miles
while Ben drives 3 miles south and 7 miles west
Use the same pythagorean theorem to find the resultant displacement
R = sqrt ( 3^2 + 7^2 )
R = sqrt ( 9 + 49 )
R = sqrt ( 58 )
R = 7.62 miles
The difference in miles to where Mary and Benjamin live will be difference in the resultant displacement of the two
Difference = 10.82 - 7.62 = 3.2 miles.
Therefore, Mary live 3.2 miles from Benjamin.
"·" - product
"+" - sum
x² - square of x
Answer: x · (6 + 8 · x²) = x(6 + 8x²)
66 rounded to the nearest hundred is 100.
If the last two digit of the number are 50 or above round up.
But....
If the last two digit of the number are 49 or below round down.
But remember also.....
If the last two digit are zeros, do not round, it is already in the hundred.
Hope this helps u.
