No because the last one is not correct and if you want to text me back if you won't me to do it for you for the first three you can
Answer:
vertex = (- 7, - 87)
Step-by-step explanation:
given a parabola in standard form : ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
p² + 14p - 38 is in standard form
with a = 1, b = 14, c = - 38, hence
= - 
= -7
substitute x = - 7 into the equation for corresponding value of y
y = (- 7)² + 14(- 7) - 38 = 49 - 98 - 38 - - 87
vertex = (- 7, - 87)
Answer:
2 hours
Step-by-step explanation:
The question is asking us to get the meeting point of the two and at what time would they arrive here given their individual speeds. Now what needs to be done here is first add their average speeds.
The total average speed = 325 + 25 = 350km/h
Now the distance the helicopter would have traveled would be ; 325/350 * 700 = 650km
The remaining distance left for the boat would be 700 - 650 = 50km
Now the time taken for this would be 650/325 or 50/25 = 2hours
Answer:199---3
Step-by-step explanation:
What you do is add up the coins in two piles
1. all the coins added up
2.coins that are more than 10 cents (or equal)
take number 2 and put that in the numerator (top spot on a fraction)
and take number 1 and put it on the denominator (bottom spot on a fraction)
then simplify it if needed.
50/224 is the raw data simplify it for the real answer
25/112 is the simplest you can do so there's your answer. hope this helped :)
