Answer:
The answer is approximately 5.09 seconds.
Step-by-step explanation:
The given equation is:
f(x) = -5x^2 + 250
To find the elapsed time, x, set the equation equal to 120 and solve for x:
-5x^2 + 250 = 120
-5x^2 = -130
x^2 = -130/-5 = 26
x = Sqrt(26) = 5.09 seconds.
Answer:
Recursive formulas give us two pieces of information:
The first term of the sequence
The pattern rule to get any term from the term that comes before it
So I think A.Pattern
Answer:
z = 70
Step-by-step explanation:
Multiply by 25 on both sides:
14/5 = z/25
25(14/5) = (z/25)
25(14/5) = z
Divide:
25(14/5) = z
25(2.8) = z
Multiply:
25(2.8) = z
70 = z
Answer:
x = 26.89352
Step-by-step explanation:
1. remove parenthesis
2. divide both sides by 14
