Answer:
When t=2.1753 & t=.5746 , h=27
Don't worry, I got you. Also, my calculator does too.
We set h equal to 27, because we want the height to be 27 when we solve for t.
That leaves us with:
27 = 7 + 44t - 16t^2
Simplify like terms,
20 = 44t - 16t^2
Move 20 onto the right side, so we can use quadratic equation
44t - 16t^2 - 20 = 0 --> -16t^2 + 44t - 20
Using quadratic, you get
t=2.1753 & t=.5746

Answer:
a no solution
b is all real numbers
c x=12
Step-by-step explanation:
a has no values of x that make it true
b any value of x makes it true
c simplify both sides of the equation then isolate x
A. -f(1)=1,f(2)=2,f(n)=2f(n-1)f(n-2);n>2
372 is the answer.
(9*6*3)+(10*7*3)=372
