Answer:
These 2 points on a graph are 17 units apart.
Step-by-step explanation:
Y Coordinate is the same for both points, all you need to know is the change in X coordinates.
Answer:
182 feet
Step-by-step explanation:
The equation that describes the motion of the hot air ballon is:
where:
is the initial altitude
v is the rate of descend of the balloon
t is the time
The balloon starts from a height of
and has a rate of descend of
Therefore, after time
t = 12 min
Its altitude will be
Remark
This may be a little confusing, but because they are travelling in opposite directions, the distances add when you want to get how far apart they are.
d1 + d2 = 1541
Equation
Let the time this happens = t
d1 = 323*t
d2 = 347*t
323*t + 347*t = 1541 Combine like terms on the left.
670t = 1541 Divide by 670
t = 1541/670
t = 2.3 hours pass before the distance of 1541 miles are between the two planes. You might need the answer to be 2 hours 18 minutes.
5s subshell represent that n is equal to 5 and l is equal to 0.
2p subshell represent that n is equal to 2 and l is equal to 1.
3d subshell represent that n is equal to 3 and l is equal to 2.
The numbers gives us the value of n and the letter gives us the value of l.
s means l = 0
p means l = 1
d means l = 2
f means l = 3
