Answer:
n=0
Step-by-step explanation:
because 0 would be the only number that would make both sides equal
( i know it not the best explanation )
F(5)+G(7) is equal to 1835
B.)
I can tell because the sin func starts from the top at 0 (if sin is positive)
The correct answer is C. Commutative Property
Answer: 1.4 seconds
<u>Step-by-step explanation:</u>
The equation is: h(t) = at² + v₀t + h₀ where
- a is the acceleration (in this case it is gravity)
- v₀ is the initial velocity
- h₀ is the initial height
Given:
- a = -9.81 (if it wasn't given in your textbook, you can look it up)
- v₀ = 12
- h₀ = 3
Since we are trying to find out when it lands on the ground, h(t) = 0
EQUATION: 0 = 9.81t² + 12t + 3
Use the quadratic equation to find the x-intercepts
a=-9.81, b=12, c=3

Note: Negative time (-0.2) is not valid
