Answer:
It hit the ground at t=2
It reaches its highest point at t=1
Its maximum height =16
Step-by-step explanation:
The graph of the function of the height will be a parapola opening downward where it's x intercepts = the time where the object hit the ground and its maximum point = the point with the maximum point
The x intercepts are 0 when the object was thrown and 2 when it landed
The x coordinate of the vertex is in the middle of the two x intercepts so it will be 1
Substituting the x coordinate of the vertex gives us the y coordinate of the vertex which is the maximum hight 16
$50.40 since 12% of 45 is $5.40
5.4+45=50.4
Answer:
I'm gonna go a little out of order.
To determine b, find where the line crosses the <em>y</em>-axis. If it's positive, put it as " + " and if it's negative, put it as " - ".
To determine m, find two points on the line that are directly on the number. Example, choose (4, 1) instead of (4.1, 5.2). Go up/down and left/right (while making sure to count) until you reach the second number. going up and right will be considered positive while down and left are considered negative.
Using rise/run, put your number for up/down as a numerator over your left/right, which will be a denominator.
Insert <em>m</em> and <em>b</em> and you're good to go!
Answer:
0.4
Step-by-step explanation:
Multiply without the decimal points, then put the decimal point in the answer
2 has 0 decimal places
0.2 has decimal place
Therefore the answer has 1 decimal places
Answer:
28 2/3
Step-by-step explanation:
1 1/4 + 1 2/3 + 25 3/4
5/4 + 5/3 + 103/4
15/12 + 20/12 + 309/12
344/12
172/6
86/3
= 28 2/3
