Answer: The ball hits the ground at 5 s
Step-by-step explanation:
The question seems incomplete and there is not enough data. However, we can work with the following function to understand this problem:
(1)
Where 
models the height of the ball in meters and 
the time.
Now, let's find the time when the ball Sara kicked hits the ground (this is when 
):
(2)
Rearranging the equation:
(3)
Dividing both sides of the equation by 
:
(4)
This quadratic equation can be written in the form 
, and can be solved with the following formula:
(5)
Where:
Substituting the known values:
(6)
Solving we have the following result:
This means the ball hit the ground 5 seconds after it was kicked by Sara.
0.05% of 40 is
0.02 Divide your decimal by 100:
Multiply your decimal with 40:
5 degrees. Since its a right triangle, one of the angles is a right angle meaning it measures 90 degrees and 90+85=175 degrees and because of the Triangle Sum Theorem, we know a triangle equals 180 degrees. So 180-175= 5 degrees.
Answer:
nope cant even think not meh
Step-by-step explanation:
sorry
Assuming that X represents the number of hours worked and f(x) the number of cars washed, the equation would be f(x)=11x+14x.
The 11x represents the number of cars washed by Arianna in x number of hours and the 14x represents the number of cars washed by Matthew in x number of hours. You add the two because they are each washing their own car at their own pace but working on one lot.
