The area of a square is S^2 with S as one side. To find the length of the side, simply work the formula backwards. The square root of 400 is 20. Hope this helps! :)
Answer:
there are 3 roots at x=+-1, +3, +4
Step-by-step explanation:
U find multiples of both denominators and then us the least number that matches both as the new denominator then multiply your other two fractions to get the same denominator that u got in your multiples and then multiply whatever number you have with your number you multiply by to get the denominator on both fractions
not very good at explaining things but I really hope this helps
Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s
Answer:
It's a line parallel to the y-axis
Step-by-step explanation:
Note that the similar x value in both coordinates.
Then it's a line drawn parallel to the y-axis
Therefore, the slope is infinite as it makes a right angle with the x-axis.
