Answer: 5.5 seconds
Since the penny is dropped and not thrown, the initial velocity is 0 and the initial height is given as 150m. Plugging these into the given equation result in 
. To find how long it will take for the penny to hit the ground we set the equation equal to zero and solve for t. Since this doesn't factor, you'll need to use the quadratic formula:
. Since time cannot be negative, the answer will be the positive 5.5 seconds.
Answer: A line with a slope of 2
Step-by-step explanation: the slope of the line is -1/2 so the negative reciprcal of the slope is 2 (It would be perpendicular to it)
i used m=y2-y2/x2-x1 to figure ou the slope and -(x/y) as the negative reciprcal for the perpendicular line.
Answer:
6 and 8 minutes
Step-by-step explanation:
The graph shows her speed as being the highest and the table backes it up. 40mph is her top speed
Answer:
300ml
Step-by-step explanation:
Large Bottle = 500ml
Medium Bottle = 60/100 × 500ml
<u>60</u> × 500← <em>cancel the two zeroes.</em>
100←
60 × 5
= 300ml
A vertex is the common point that two lines or rays diverge from.
