"how long..." is asking for time (t). "The amount of time spent in the air" is the time from when the ball was kicked (0 seconds) to the time it landed on the ground. Need to find the x-intercepts (one will be negative which will be invalid). You can do this by factoring ... <em>or by using the quadratic formula.</em> With the equation you provided, it is not factorable, so you must use the quadratic formula.
h = -16t² + 60t + 3
a=-16 b=60 c=3





or 
or 
t = -0.05 or t = 3.8 <em>disregard the negative</em>

Answer:
Wilhem
Step-by-step explanation:
The given equation is

Step 1 : Add 32g and 8g.



Step 2: Subtract 10 from 40.


Step 3: Divide both sides by 30, find the value of g.


The value of g is 5.
Therefore, Wilhem is correct.
Answer:
16 miles
Step-by-step explanation:
The height is 26 miles. Multiply that by 2 which gets 52 and then subtract that from 84. That gives you 32 which means the sum of the lengths is 32/2 which is 16 miles
Answer:
No, it is not in scientific notation. The first factor is not greater than or equal to 1.
Step-by-step explanation:
Scientific notation is a method of writing numbers as the product of two factors where the first factor is a number whose absolute value is greater than or equal to 1 but less than 10.
