Adding a negative interference is the same as subtracting a positive integer
This is a tough one. What we are looking for is how long (how much time) was spent in the mountains. So we are looking for t, time. 3 hours 48 minutes is 3.8 hours. Both have to be in terms of one or the other, you cant have unknown mountain time and plain time, so let's say that mountain time is t. That means that plain time is 3.8-t. Multiply the rates times the times for each and add them together and set them equal to the total distance. 90(3.8-t)+37.5t=300. Solve for t. The time spent in the mountains was 48 minutes
Probably 2500 or less because they dont need that much hawks.
Answer:
You can find the answer by using the formula t=-b/2a
Step-by-step explanation:
Remember the maximum height will be at the vertex. The x value of the vertex is your time, so use x=-b/2a except that t is your x. Then if it had also asked what the height was, you would plug that answer into your equation to find the y value of the vertex. Pretty sure your teacher is just asking you to find the x though:)
, where <em>a</em> is the initial amount, <em>b</em> = 1 + <em>r</em> (the growth rate as a decimal number) and <em>x</em> is the number of time periods (in this case, minutes). Substituting the information we have:
. To the nearest tenth of a gram, this would be 1.0 grams.
