(a) Coordinates:
A (0, 0)
B (3, 2)
C (9, 6)
Triangle A to B has a change of +3 in x values, but Triangle B to C has a change of +6 values so each triangle doesn’t have the same changes in x values.
Triangle A to B has a change of +2 in y values, Triangle B to C has a change of +4 values so each triangle doesn’t have same change in values.
Triangle A to B change in y over change in x = 2/3, Triangle B to C change in y over change in x = 4/6, both have decimal values of 0.66. Therefore, each triangles has the same ratio of change in y over change in x.
You would have to set the equation to the profit Jennifer got, which you know to be 63 dollars:
63=0.5e-5
To begin solving for e, which represents the number of erasers sold, add five to each side to get e alone.
68=0.5e
Multiply each side by two to get a whole x value on the right side
136=e
Jennifer sold 136 erasers
Answer:
$6.30
Step-by-step explanation:
So we are going to subtract what is owed by what is payed back to find out how much John owes his brother
$25.75 - $19.45 = $6.30
John owes his brother $6.30
Area = Base*Height so Base = Area/Height = 39.2/5.6 = 7 units.
The time taken by the object to fall from 15 m on the Mercury which has a gravity of 3.7 m/s² is 10.54 seconds.
<h3>What is kinematics?</h3>
It is the study of the motion of a body without considering mass. And the reason behind them is neglected.
The object is on Mercury and starts falling from rest.
As it is on Mercury there is no air resistance to account for.
Gravity on Mercury is 3.7 m/s².
Then the time taken by the object to fall from 15 m will be given as
