Answer:
12. 1 second, 35 ft; 2 seconds, 32 ft
13. (t, y) = (1.4 seconds, 37.6 feet)
14. 37.6 ft; the vertex is the highest point
Step-by-step explanation:
12. You have properly answered question 12.
After 1 second, the height is 35 feet; after 2 seconds, it is 32 feet.
__
13. My method of choice is to plot the graph on a graphing calculator and let it show me the coordinates of the vertex when I highlight that point. (See attached.) The vertex is ...
(t, y) = (1.4, 37.6)
__
14. The graph is a graph of height when the object is launched with a vertical velocity of 45 ft/s. So, the maximum of the graph will correspond to the maximum height of the object. The vertex is that maximum point, and its y-coordinate is that maximum height.
The maximum height is 37.6 feet.
Consecutive numbers can be written as such:
n + (n + 1) = 73
Open the parentheses and simplify:
2n + 1 = 73
Subtract 1 from both sides:
2n = 72
Divide both sides by 2:
n = 36
The numbers are 36 and 37
Pi is seldom useful as an exponent, and is hardly ever used as one.
If you need to show somebody an example of an exponent, I think
that pi is one of the worst examples you can choose.
Answer:
320
Step-by-step explanation:
go backwards, 75 + 45 = 120
120 * 5/3 = 200
200+40 = 240
240 *4/3 = 320
The unit measurement of the a volume in mm is mm³(millimetres cube.)
<h3>How to find volume ?</h3>
Volume is is defined as the space occupied within the boundaries. The objects are usually solid objects.
The volume of a 3 dimensional figure is the product of the base area and the height.
Therefore, the units of volume is measured in cubic units.
The volume of a prism with side lengths measured in millimetres is 20.
Therefore, the measurement can be represented as follows:
20 mm³
