Answer:
If x = time in seconds, the answer is 1 second.
Step-by-step explanation:
The question is asking for the maximum height and the time it was achieved, so in terms of a graph, it is the vertex coordinates. Luckily this equation is in vertex form, so it gives us those points. The -1 in the equation is the x, but you invert this sign, because even thought the value on the graph is positive, it tells you to subtract 1, therefore adding -1, so for this part (the x part of the equation) remember to invert the sign.
The other part (the height) comes from the equation adding 45 at the end. This is the highest y point, and therefore the answer is (1,45), 1 second for 45 meters high.
Answer:
<em>The ferry can travel of the distance between the two ports in one hour.</em>
Step-by-step explanation:
A ferry traveled of the distance between two ports in hour.
Suppose, the ferry traveled of the distance between the two ports in one hour.
So, the <u>equation according to the ratio of "distance" to "time"</u> will be.......
Thus, the ferry can travel of the distance between the two ports in one hour.
Answer:
The answer is 3.64m
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 30= 3/h. You divide cos 30 by 3 and you get the answer of 3.64m rounding to 2 decimal places.
