Answer:
x=(-2/3)
Step-by-step explanation:
(9x+13)^2=49
√(9x+13)^2=√49
9x+13=7
9x+13-13=7-13
9x=-6
9x÷9=-6/9
x=-6/9
-6/9=-2/3
Answer: Felipe= 106
Teresa=98
Pablo=464
Step-by-step explanation:
Since Pablo has 4 times you do $106x4=464 and Teresa has 8 less so $106-8= $98
Ah, thank you. your question truly made the most of sense.
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
I'd say A. 8000, because you'd get the most answers and the biggest variety in answers for a more accurate sample.
