y=-2x+2
Step-by-step explanation:
Answer:
Step-by-step explanation:
Assuming that you need to simplify the expression, below is the explanation to do it.
Given the following expression:
You need to decompose the radicand (The number inside the square root) into its prime factors:
Knowing that, you can rewrite the expression in this form:
Since , you must substitute it into the expression:
Now you need to remember the following property:
Then, applying that property, you get:i:
Finally, you must divide the numerator and the denominator by 3. So, you get:
No, it is not. This is because "%" refers to "percent" which means per hundred or over one hundred. Therefore, 0.6% = 0.6*0.01 = 0.006$.
Answer:
Height = 250km
Step-by-step explanation:
Given,
rate of rise of ballon 1 = 38 km/h
rate of rise of ballon 2 = 50 km/h
Let the time after which both the ballons will reach same height be 't'.
hence, after 't' hours,
⇒ height of ballon 1 = height of ballon 2
⇒ 38t + 60 = 50t
⇒ 12t = 60
⇒ t = 5 hours
so, the height at which both the ballons will be at the same height will be 250km.
