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.
Answer:
<em>48 drops of red food coloring</em>
Step-by-step explanation:
32/8 = 4
SO she uses 4x as much yellow food coloring meaning you need to use 4x as much red food coloring.
4 x 12 = 48 so she needs to add 48 drops of red food coloring
2500Y + 35,885 = 250,000
2500Y +35885 -35885= 250,000 - 35885
2500Y/2500 = 214115/2500
Y= 85.64
85 years is the answer
y=years
Answer:
11.33 or 34/3
Step-by-step explanation:
6x+23+9x−13=180
Step 1: Simplify both sides of the equation.
6x+23+9x−13=180
6x+23+9x+−13=180
(6x+9x)+(23+−13)=180
15x+10=180
15x+10=180
15x+10−10=180−10
15x=170
