3 meters per minute is the rate.
7.5/3 = how much minutes he walked.
7.5/3 = 2.5
Answer: It walked for 2.5 minutes.
So, dimensional analysis will help with this
Hope this helps!
Answer:
Step-by-step explanation:
|7-10|=3
absolute value of any number is always positive
<u>Solution</u><u>:</u><u>-</u>
Let's find roots of x² - 3x + 2
=> x² - 3x + 2 = 0.
=> x² - x - 2x + 2 = 0.
=> x ( x - 1 ) -2 ( x - 1) = 0.
=> ( x - 1 ) ( x - 2 ) = 0.
=> x = 2, 1.
Now
- ( a + ß )² = (2+1)²=3²=9
- ( a - ß )² = ( 2 - 1 )² = 1² = 1.
So , equⁿ would be ,
=> x² - ( 9 + 1)x + 9×1=0.
<u>=> x² - 10x + 9=0.</u>
Two divided by twenty-two is .090909 repeating
